[PMID: 38421413 DOI: 10.1007/s00402-024-05225-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/26/2023] [Accepted: 02/15/2024] [Indexed: 03/02/2024]
Abstract
BACKGROUND Comorbid cardiovascular diseases have been associated with poor outcomes in total knee arthroplasty (TKA); however, our understanding of TKA with prior cardiac treatment procedures has largely been undocumented. In this study, we examined TKA patients who had undergone different cardiac interventions that addressed their condition. The purpose was to characterize and compare outcomes for a growing patient population not yet analyzed. MATERIALS AND METHODS The 2016-2019 Nationwide Inpatient Sample database was queried for 558,256 patients who had TKA (ICD-10CM). Backgrounds significant for pacemaker [PM] (n = 8025), coronary artery bypass [CABG] (n = 12,683), heart valve surgery [HV] (n = 4125), or coronary stent [CS] (n = 19,483) were compared against those without, across demographics, admission information, and various complications. RESULTS Cardiac interventions were associated with increased age, male gender, length of stay, and cost of care. CABG, and Stent groups had more diabetics, but HV had significantly fewer (p = 0.008). PM and HV had significantly less tobacco use and, in addition to CABG, less obesity. Postoperatively, mortality was elevated in the PM [Odds ratio (OR) 2.89, p = 0.008], CABG (OR 2.53, p = 0.006) and CS group (OR 1.94, p = 0.018), but not HV. Myocardial infarctions were elevated in the CABG (OR 3.874) and CS group (OR 5.11) (p < 0.001). PM, HV, and CS had increased odds of periprosthetic fracture by 2.15-fold (p < 0.001), 2.09-fold (p < 0.001), 1.29-fold (p = 0.011) respectively. HV saw increased periprosthetic mechanical complications (OR 1.48, p = 0.006). CABG increased the odds of deep surgical site infection 14.23-fold and CS 9.22-fold (p < 0.001). Postoperative pneumonia was increased in PM, CABG, and CS groups (OR 2.15,), (OR 2.21,), (OR 1.64,) (p < 0.001). CONCLUSIONS Patients who have undergone cardiac intervention are generally at risk for adverse stays. Furthermore, risk factors and complications vary between the groups. Our analysis emphasizes the importance of individualized medical care and as a basis for electing and informing patients for TKA.

What are the predisposing factors for periprosthetic fractures following total hip arthroplasty? - a National Inpatient Sample-based study. Arch Orthop Trauma Surg 2024:10.1007/s00402-024-05343-0. [PMID: 38661998 DOI: 10.1007/s00402-024-05343-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/01/2024] [Accepted: 04/15/2024] [Indexed: 04/26/2024]
Abstract
INTRODUCTION With a progressive rise in the number of total hip arthroplasties (THA) over the past decades, the proportion of patients sustaining peri-prosthetic fractures (PPF) has been substantially increasing. In this context, the need for clearly understanding the factors predisposing patients to PPF following THA and the impact of these adverse complications on the overall healthcare burden cannot be understated. MATERIALS AND METHODS Based upon the Nationwide Inpatient Sample (NIS) database, the patients who underwent THA in the United States between 2016 and2019 (with ICD-10 CMP code) were identified. The patients were divided into 2 groups; group A - patients who sustained PPF and group B - those who did not. The information about the patients' demographic profile, medical comorbidities; and hospital admission (including length of stay and expenditure incurred) were analysed; and compared between the 2 groups. RESULTS Overall, 367,890 patients underwent THA, among whom 4,425 (1.2%) sustained PPF (group A). The remaining patients were classified under group B (363,465 patients). On the basis of multi-variate analysis (MVA), there was a significantly greater proportion of females, elderly patients, and emergent admissions (p < 0.001) in group A. The length of hospital stay, expenditure incurred and mortality were also significantly higher (p = 0.001) in group A. Based on MVA, Down's syndrome (odd's ratio 3.15, p = 0.01), H/O colostomy (odd's ratio 2.09, p = 0.008), liver cirrhosis (odd's ratio 2.01, p < 0.001), Parkinson's disease (odd's ratio 1.49, p = 0.004), morbid obesity (odd's ratio 1.44, p < 0.001), super obesity (odd's ratio 1.49, p = 0.03), and H/O CABG (coronary artery bypass graft; odd's ratio 1.21, p = 0.03) demonstrated significant association with PPF (group A). CONCLUSION Patients with PPF require higher rates of emergent admission, longer hospital stay and greater admission-related expenditure. Female sex, advanced age, morbid or super obesity, and presence of medical comorbidities (such as Down's syndrome, cirrhosis, Parkinson's disease, previous colostomy, and previous CABG) significantly enhance the risk of PPF after THA. These medical conditions must be kept in clinicians' minds and close follow-up needs to be implemented in such situations so as to mitigate these complications.

Patient disposition after discharge following primary total hip arthroplasty: home versus skilled nursing facility-a study based on national inpatient sample database. Arch Orthop Trauma Surg 2024; 144:937-945. [PMID: 37819436 DOI: 10.1007/s00402-023-05081-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/22/2023] [Accepted: 09/17/2023] [Indexed: 10/13/2023]
Abstract
INTRODUCTION In view of the shortened length of hospital stay following THA, an increasing proportion of patients have required transfer to "extended-care" (ECF) or "skilled nursing" facilities (SNF) over the past years. As a result, the expenditure related to postoperative care facility has been acknowledged as a crucial component of total economic burden associated with THA. In this context, the clinical and demographic factors leading to the need for transfer of patients to SNF following primary THA need to be clearly understood. METHODS The NIS database was utilised to identify the patients, who underwent primary THA between 2016 and 2019. The patients were then grouped under two categories: group A-patients who required post-THA transfer to SNF; and group B-those who were discharged home. The details regarding patients' demographic profile, medical comorbidities and complication profile during the perioperative period were recorded; and compared between groups A and B. RESULTS Based on the database, 368,431 patients underwent primary THA between 2016 and 2019; among whom, 67,498 (18.3%) were transferred to SNF (group A) following the surgery. Among the various comorbidities evaluated [on multivariate analysis (MVA)], uncomplicated DM (OR 1.45; p < 0.001), CKD (OR 1.47; p < 0.001), cirrhosis (OR 1.83; p < 0.001), Parkinson's disease (OR 3.94; p < 0.001), previous H/O dialysis (OR 2.84; p < 0.001), colostomy (OR 2.03; p < 0.001) or organ transplant (OR 1.42; p < 0.001); morbid obesity (OR 1.72; p < 0.001), cocaine abuse (OR 1.76; p < 0.001); and legal blindness (OR 2.58; p < 0.001) were associated with significantly greater need for post-THA transfer to SNF. Among the systemic complications reviewed (on MVA), pneumonia (odds ratio 3.2; p < 0.001), DVT (odds ratio 2.58; p < 0.001), higher need for blood transfusions (odds ratio 2.55; p < 0.001), ARF (odds ratio 2.32; p < 0.001), MI (odds ratio 2.2; p < 0.001), anaemia (odds ratio 1.65; p = 0.002) and PE (odds ratio 1.56; p < 0.001) significantly raised the probability of need for higher discharge destinations. In addition, prosthesis-related local complications such as prosthetic dislocation (OR 1.59; p < 0.001), fracture (OR 2.64; p < 0.001) or early peri-prosthetic infection (PPI; OR 1.71; p = 0.01) also necessitated specialised facilities of care following THA. CONCLUSION We could observe that 0.2% of patients required transfer to SNF following primary THA. Comorbidities such as Parkinson's disease, previous H/O dialysis, legal blindness and H/O colostomy had the highest odds of necessitating patient disposition to SNF. The occurrence of one or more systemic complications including pneumonia, DVT, ARF, MI, PE, and blood loss anaemia (or need for blood transfusion) or local prosthesis-related complications (dislocation, fracture or infections) substantially increased the chances of requiring transfer to a specialised care facility.

Factors that increase the rate of periprosthetic dislocation after reverse shoulder arthroplasty. ARTHROPLASTY 2023; 5:57. [PMID: 38041138 PMCID: PMC10693107 DOI: 10.1186/s42836-023-00214-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/14/2023] [Accepted: 09/15/2023] [Indexed: 12/03/2023] Open
Abstract
INTRODUCTION Reverse shoulder arthroplasty (RSA) is considered one of the greatest technological innovations in shoulder reconstruction surgery, as evidenced by the fact its growth rate of usage is greatest among all shoulder arthroplasties. However, like all arthroplasties, a post-surgical complication often arises. One of these complications, periprosthetic dislocation (PPD), requires revision and poses, therefore, a burden on both patients and healthcare providers. While PPD is understood to be a complication of RSA, it is unclear to what extent certain risk factors and co-morbidities predispose patients to post-RSA PPD. The purpose of this study was to identify and evaluate the impact of specific risk factors and co-morbidities that contribute to the development of PPD following RSA. METHODS In this retrospective study, we used the Nationwide Inpatient Sample (NIS) database from 2016-2019 to analyze the prevalence and impact of various risk factors and co-morbidities on the incidence of PPD following RSA. A univariate and subsequent multivariate logistic regression model was made to provide a descriptive association between variables that impact the rates of PPD after RSA. RESULTS The NIS database identified 59,925 patients, 1,000 of whom experienced a PPD while the remaining 58,825 were placed in the non-PPD group (controls). The PPD group consisted predominantly of females (53.10%) and Caucasians (86.30%). There was a higher incidence of tobacco-related disorders (P = 0.003), obesity (P < 0.001), morbid obesity (P < 0.001), liver cirrhosis (P < 0.001), and Parkinson's disease (PD) (P < 0.001) in PPD patients compared to controls. Young patients had a 1.89-fold increased odds (OR: 1.89, 95% CI [1.58, 2.26], P < 0.001), patients with tobacco-related disorders had decreased odds (OR: 0.80, 95% CI [0.67, 0.97], P = 0.02), morbidly obese patients had 1.50 times the odds (OR: 1.50, 95% CI [1.14, 1.97]), liver cirrhosis patients had 2.67-fold increased odds (OR: 2.67, 95% CI [1.55, 4.60], P < 0.001), and Parkinson's disease patients had 2.66 times the odds (OR: 2.66, 95% CI [1.78, 3.96], P < 0.001) to develop PPD following RSA compared to patients who did not have the corresponding condition. CONCLUSIONS Patients with specific risk factors and co-morbidities are predisposed to developing PPD after RSA. Risk factors that were found to be associated with a higher incidence of PPD are gender (female), race (Caucasian), and age (young patients). Analysis revealed the history of tobacco-related disorder, obesity, morbid obesity, liver cirrhosis, and Parkinson's disease increased the odds of developing PPD following RSA. These findings can inform both healthcare providers and patients to improve RSA surgical outcomes and tailor post-surgery recovery programs to fit the patient's needs.

Understanding factors that impact the length of stay after total hip arthroplasty - A national in-patient sample-based study. J Clin Orthop Trauma 2023; 46:102284. [PMID: 38046927 PMCID: PMC10687332 DOI: 10.1016/j.jcot.2023.102284] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/20/2022] [Revised: 07/15/2023] [Accepted: 11/15/2023] [Indexed: 12/05/2023] Open
Abstract
Background Total hip arthroplasty (THA) is increasingly used every year; however, there is currently limited information on factors that impact the length of stay (LOS) following the procedure. Longer LOS following THA is met with an increase in the cost of care, necessitating studies to identify factors that may impact LOS. Methods In this retrospective study, we used the Nationwide Inpatient Sample (NIS) database from 2016 to 2019 to analyze the preoperative comorbidities and postoperative complications that impact the LOS following THA. We divided our cohort into patients with a LOS greater than two days, and patients with a LOS less than two days. Results A total of 367,890 patients were identified in the NIS database who underwent THA during the study period. Of this cohort, 112,288 (30.52%) patients were identified as having a LOS greater than two days, while the remaining 255,602 (69.48%) patients were patients who had a LOS less than two days. Multivariate analysis demonstrated several pre-operative factors, such as diabetes, systemic lupus erythematosus, organ transplant, dialysis, the human immunodeficiency virus, chronic kidney disease, and Parkinson's disease, were independently associated with a higher risk of a LOS greater than two days. The subsequent multivariate analysis for post-operative variables demonstrated that acute renal failure, myocardial infarction, blood loss anemia, blood transfusion, pulmonary embolism, deep vein thrombosis, periprosthetic fracture, periprosthetic mechanical complications, periprosthetic infections, and wound dehiscence were all independently associated with a higher risk of a LOS greater than two days. Conclusions Several pre-operative comorbidities and postoperative complications were found to increase the likelihood of a LOS greater than two days. In addition, the group with a LOS greater than two days incurred a higher cost of care. This information is useful for providers to make informed decisions regarding patient care and resource utilization for patients undergoing THA, potentially reducing LOS.

Hospital characteristics and perioperative complications of Hispanic patients following reverse shoulder arthroplasty-a large database study. ARTHROPLASTY 2023; 5:50. [PMID: 37789382 PMCID: PMC10548760 DOI: 10.1186/s42836-023-00206-2] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2023] [Accepted: 08/22/2023] [Indexed: 10/05/2023] Open
Abstract
BACKGROUND Hispanic patients are the youngest and fastest-growing ethnic group in the USA. Many of these patients are increasingly met with orthopedic issues, often electing to undergo corrective procedures such as reverse shoulder arthroplasty (RSA). This patient population has unique medical needs and has been reported to have higher incidences of perioperative complications following major procedures. Unfortunately, there is a lack of information on the hospitalization data and perioperative complications in Hispanic patients following procedures such as RSA. This project aimed to query the Nationwide Inpatient Sample (NIS) database to assess patient hospitalization information, demographics, and the prevalence of perioperative complications among Hispanic patients who received RSA. METHODS Information from 2016-2019 was queried from the NIS database. Demographic information, incidences of perioperative complications, length of stay, and costs of care among Hispanic patients undergoing RSA were compared to non-Hispanic patients undergoing RSA. A subsequent propensity matching was conducted to consider preoperative comorbidities. RESULTS The query of NIS identified 59,916 patients who underwent RSA. Of this sample, 2,656 patients (4.4%) were identified to be Hispanic, while the remaining 57,260 patients (95.6%) were found to belong to other races (control). After propensity matching, Hispanic patients had a significantly longer LOS (median = 1.4 days) than the patients in the control group (median = 1.0, P < 0.001). The Hispanic patients (89,168.5 USD) had a significantly higher cost of care than those in the control group (67,396.1 USD, P < 0.001). In looking at postoperative complications, Hispanic patients had increased incidences of acute renal failure (Hispanics: 3.1%, control group: 1.1%, P = 0.03) and blood loss anemia (Hispanics: 12.7%, control group: 10.9%, P = 0.03). CONCLUSIONS Hispanic patients had significantly longer lengths of stay, higher costs of care, and higher rates of perioperative complications compared to the control group. For patients who are Hispanic and undergoing RSA, this information will aid doctors in making comprehensive decisions regarding patient care and resource allocation.

What enhances the in-hospital mortality following total hip arthroplasty? A national inpatient sample-based study. Arch Orthop Trauma Surg 2023; 143:6423-6430. [PMID: 36976373 DOI: 10.1007/s00402-023-04850-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/16/2022] [Accepted: 03/18/2023] [Indexed: 03/29/2023]
Abstract
PURPOSE With prolonged life expectancy and advancements in prosthetic designs, the proportion of patients belonging to diverse age groups undergoing total hip arthroplasty (THA) has progressively increased. In this context, the details regarding risk factors associated with mortality after THA, and its prevalence need to be clearly understood. This study sought to identify the possible co-morbidities associated with post-THA mortality. METHODS Based on Nationwide Inpatient Sample (NIS) database, patients undergoing THA from 2016 to 2019 (using ICD-10CMP) were identified. The included cohort was stratified into two groups: "early mortality" and "no mortality" groups. The data regarding patients' demographics, co-morbidities, and associated complications were compared between the groups. RESULTS Overall, 337,249 patients underwent THA, among whom, 332 (0.1%) died during their hospital admission ("early mortality" group). The remaining patients were included under "no mortality" group (336,917 patients). There was significantly higher mortality in the patients, who underwent emergent THA (as compared with elective THA: odd's ratio 0.075; p < 0.001). Based on multivariate analysis, presence of liver cirrhosis, chronic kidney disease (CKD) and previous history of organ transplant increased the odds of mortality {odds ratio [Exp (B)]} after THA by 4.66- (p < 0.001), 2.37-fold (p < 0.001) and 1.91-fold (p = 0.04), respectively. Among post-THA complications, acute renal failure (ARF), pulmonary embolism (PE), pneumonia, myocardial infarction (MI), and prosthetic dislocation increased the odds of post-THA mortality by 20.64-fold (p < 0.001), 19.35-fold (p < 0.001), 8.21-fold (p < 0.001), 2.71-fold (p = 0.05) and 2.54-fold (p < 0.001), respectively. CONCLUSION THA is a safe surgery with low mortality rate during early post-operative period. Cirrhosis, CKD, and previous history of organ transplant were the most common co-morbidities associated with post-THA mortality. Among post-operative complications, ARF, PE, pneumonia, MI, and prosthetic dislocation substantially enhanced the odds of post-THA mortality.

Postoperative complications of spinal vs general anesthesia in elderly patients undergoing hip hemiarthroplasty. Arch Orthop Trauma Surg 2023; 143:5615-5621. [PMID: 37061659 DOI: 10.1007/s00402-023-04876-0] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/08/2023] [Accepted: 04/03/2023] [Indexed: 04/17/2023]
Abstract
INTRODUCTION Elderly patients with hip fractures are at high risk for mortality due to postsurgical complications. Hip hemiarthroplasty is a routine procedure done in elderly patients for surgical repair of femoral neck fractures. Both general and spinal anesthesia can be used in elderly patients undergoing hemiarthroplasty. Rates of postoperative complications among the two anesthetic choices have not been directly compared. In this study, we compare the rates of postoperative complications in elderly patients (age greater than 70) undergoing hip hemiarthroplasty for femoral neck fractures using a national database. METHODS Data for the years 2015-2020 from the National Surgical Quality Improvement Program (NSQIP) were used for the study. Patients greater than 70 years of age who received a hip hemiarthroplasty with general anesthesia or spinal anesthesia were identified using CPT procedure codes. Pertinent preoperative variables and rates of postoperative complications were characterized and analyzed. RESULTS Our study found that elderly patients who received spinal anesthesia had, on average, longer length of stays but shorter operative times compared to patients who received general anesthesia. Furthermore, we found that patients who received spinal anesthesia had lower rates of systemic sepsis, cardiac arrests, and blood transfusions when compared to patients who received general anesthesia. Finally, we found that overall rates of mortality were significantly lower in the spinal anesthesia cohort compared to the general anesthesia cohort. CONCLUSION Our work suggests that patients who underwent spinal anesthesia for hip arthroplasty may have lower rates of postoperative complications. This work further highlights the role of anesthetic choice in preventing complications following hip hemiarthroplasty procedures.

Abstract
BACKGROUND Cocaine use has surged in the past decade, with 4.8 million Americans (1.7% of the population greater than 12) reporting use in 2021, leading to a healthcare burden of 1.3 billion dollars. Cocaine users experience prolonged hospital stays, higher costs, worse surgical outcomes, increased risk of medical conditions, and inflammation-related osteoarthritis. The study aims to identify factors influencing length of stay, costs, and perioperative complications in cocaine users undergoing total hip arthroplasty (THA) to reduce these risks. METHODS This study utilized the NIS database, providing comprehensive information on patient demographics, length of stay, hospital costs, and complications. Statistical analyses were conducted using SPSS software, including propensity matching and significance testing, to compare outcomes between cocaine users (CU) and non-cocaine users (NCU) undergoing total hip arthroplasty. RESULTS After propensity matching, cocaine users had a significantly longer LOS (4.8 days) in comparison to non-cocaine users (2.6 days) (p < 0.001). Similarly, the CU group had a larger of care (87984.9) than the NCU group (69149.2) (p < 0.001). Cocaine users had significantly higher rates of blood loss anemia (OR: 3.24, 95% CI: 2.21, 4.73), blood loss anemia (OR: 1.59, 95% CI: 1.12, 2.24), blood transfusion (OR: 2.23, 95% CI: 1.04, 4.78), periprosthetic dislocation (OR: 6.57, 95% CI: 1.47, 29.32), and periprosthetic infection (OR: 4.59, 95% CI: 1.54, 13.68) than patients in the non-cocaine user's group. CONCLUSION Cocaine users had a significantly longer length of stay, higher costs of care, and an increased number of post-operative complications compared to non-cocaine users. These data contribute to understanding the potential ramifications of cocaine users undergoing THA.

Total knee arthroplasty in dialysis patients: a national in-patient sample-based study of perioperative complications. Knee Surg Relat Res 2023; 35:22. [PMID: 37533126 PMCID: PMC10394770 DOI: 10.1186/s43019-023-00196-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/19/2022] [Accepted: 07/18/2023] [Indexed: 08/04/2023] Open
Abstract
BACKGROUND Chronic kidney disease (CKD) is a growing disease that affects millions of people in the USA every year. Many CKD patients progress to end-stage renal disease (ESRD), necessitating the use of hemodialysis to alleviate symptoms and manage kidney function. Furthermore, many of these patients have lower bone quality and experience more postoperative complications. However, there is currently limited information on hospitalization information and perioperative complications in this population following procedures such as total knee arthroplasty (TKA). The purpose of this study was to assess the patient characteristics, demographics, and prevalence of postoperative problems among dialysis patients who received TKA. METHODS In this retrospective study, we used the Nationwide Inpatient Sample (NIS) data from 2016 to 2019 to analyze the incidence of perioperative complications, length of stay (LOS), and the cost of care (COC) among patients undergoing TKA who were categorized as dialysis patients, compared with those who were not. Propensity matching was conducted to consider associated factors that may influence perioperative complications. RESULTS From 2016 to 2019, 558,371 patients underwent TKAs, according to the National In-Sample (NIS) database. Of those, 418 patients (0.1%) were in the dialysis group, while the remaining 557,953 patients were included in the control group. The mean age of the dialysis group was 65.4 ± 9.8 years, and the mean age in the control group was 66.7 ± 9.5 years (p = 0.006). After propensity matching, dialysis group patients had a higher risk of receiving blood transfusions [odds ratio (OR): 2; 95% confidence interval (CI): 1.2, 3.4] and a significantly larger COC in comparison to those in the control group (91,434.3 USD versus 71,943.6 USD, p < 0.001). In addition, dialysis patients had significantly higher discharges to another facility, as compared with the control group patients. CONCLUSIONS The dialysis group had a significantly higher cost of care, higher rates of requiring blood transfusion, and more cases of being discharged to another facility than non-dialysis patients. This data will help providers make informed decisions about patient care and resource allocation for dialysis patients undergoing TKA.

Purpose Our aim is to investigate the length of stay (LOS), cost of care (COC) and postoperative complications associated with reverse shoulder arthroplasty (RSA) in nonagenarians (people aged 90-99 years old). Methods We used the National Inpatient Sample (NIS) database to identify 59,925 patients who underwent RSA between 2016 and 2019, including 555 nonagenarians. We investigated the incidences of various medical and orthopedic postoperative complications in nonagenarians compared to their younger counterparts, as well as compared nonagenarians undergoing elective and non-elective surgery. Results Nonagenarians were less likely admitted for elective surgery (69.9% in nonagenarians vs 92.8% in controls, p < 0.001) and were subject to longer LOS (3.5 days in nonagenarians vs 1.89 days in controls, p < 0.001) and greater COC ($91,794.69 US in nonagenarians vs $79,574.12 US in controls, p < 0.001). Nonagenarians had increased incidences of hospital mortality (0.72% in nonagenarians vs 0.06% in controls, p < 0.001), pneumonia (1.44% in nonagenarians vs 0.37% in controls, p < 0.001), blood loss anemia (22.34% in nonagenarians vs 10.12% in controls, p < 0.001), and ARF (6.85% in nonagenarians vs 2.18% in controls, p < 0.001). Nonagenarians undergoing elective RSA had fewer complications than those requiring non-elective RSA. Conclusion Nonagenarians undergoing RSA are subject to increased LOS, COC, and postoperative complications. Despite this, we feel that the associated complications can be deemed acceptable and that with adequate preparation, the benefits of a successful RSA may outweigh the associated complications in elderly patients. This is important to aid clinicians and patients in making informed decisions for patient care and resource allocation, as well as highlights room for improvement in costs and hospital stay, as well as sheds light on persistent health disparities in orthopedic surgery. Level of evidence IV.

[PMID: 37274508 PMCID: PMC10232323 DOI: 10.4055/cios22180] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/08/2022] [Revised: 08/29/2022] [Accepted: 08/29/2022] [Indexed: 09/10/2023] Open
Abstract
BACKGROUND The purpose of this study was to compare postoperative complication rates in super-obese (SO) patients with a body mass index (BMI) ≥ 50 kg/m2 undergoing total hip arthroplasty (THA) versus non-super-obese (NSO) patients undergoing THA. METHODS In this retrospective study using the National Inpatient Sample (NIS) database, 1,646 cases of THA in SO (BMI ≥ 50 kg/m2) patients were reviewed. We used International Classification of Diseases (ICD)-10 codes to assess postoperative variables including length of stay, cost of care (cost of inpatient hospitalization), and medical and surgical complications among SO patients undergoing THA compared to NSO patients before being discharged. RESULTS A comparison of demographic variables showed there were more women in both groups and nearly 17.2% of SO patients were diabetic patients, 11.1% of SO patients were tobacco users, and 74.8% of the SO patients were whites (African American, 15.1%; Hispanic, 2.9%). The mean length of stay was 3.43 days in the SO group and 2.32 days in the NSO group, and this difference was statistically significant. The cost of care was $79,784.64 for the SO group, which was significantly higher than $66,821.75 for the NSO group. The SO group also showed higher odds of developing medical complications such as anemia (odds ratio [OR], 1.555; 95% confidence interval [CI], 1.395-1.734; p < 0.001), acute renal failure (OR, 3.375; 95% CI, 2.816-4.045; p < 0.001), pneumonia (OR, 2.319; 95% CI, 1.241-4.331; p = 0.014), and need for blood transfusion (OR, 1.596; 95% CI, 1.289-1.975; p < 0.001). The SO patients also showed a higher risk of several postoperative surgical complications such as periprosthetic fractures, infection, and wound dehiscence. CONCLUSIONS Postoperative complication rates in SO patients were higher than those in the NSO group. Length of stay and cost of care were higher, whereas the mean age was lower for the SO group. Therefore, THA in SO patients should be undertaken only after careful consideration and preferably in a tertiary facility capable of handling all medical and surgical in-hospital complications.

Perioperative complications of legally blind patients undergoing total hip arthroplasty - A national in-patient sample database study. J Orthop 2023; 40:47-51. [PMID: 37188145 PMCID: PMC10172850 DOI: 10.1016/j.jor.2023.04.019] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/13/2023] [Accepted: 04/21/2023] [Indexed: 05/17/2023] Open
Abstract
Background Legally blind patients are more prone to injury-related falls, which may lead to hip fractures, often necessitating total hip arthroplasty (THA), as a corrective procedure. Many of these patients have unique medical needs and have increased rates of perioperative complications following surgical procedures. However, there is limited information on the hospitalization data and perioperative complications in this population following guidelines such as THA. The purpose of this study was to evaluate the patient characteristics, demographics, and prevalence of perioperative issues among THA patients who were legally blind. Methods Using 2016-2019 data from the Nationwide Inpatient Sample (NIS), the incidence of perioperative complications, length of stay (LOS), and the cost of care (COC) among patients undergoing THA who were categorized as legally blind patients, compared to those who were not were analyzed. Propensity matching was conducted to consider associated factors that may influence perioperative complications. Results From 2016 to 2019, 367,856 patients underwent THA, according to the NIS. Of those, 322 (0.1%) patients were categorized as legally blind, and the remaining 367,534 (99.9%) patients were not identified as legally blind (control). Legally blind patients were significantly younger than the control group (65.4 years vs. 66.7 years, p < 0.001). After propensity matching, legally blind patients had longer LOS (3.9 days vs. 2.8, p = 0.04), increased discharges to another facility (45.9% vs. 29.3%, p < 0.001), and fewer discharges to home (21.4% vs. 32.2%, p = 0.02) than control patients. Conclusions The legally blind group had significantly longer LOS, higher rates of discharge to another facility, and lower rates of discharge to home compared to the control group. This data will help providers make informed decisions about patient care and resource allocation for legally blind patients undergoing THA.

Total Hip Arthroplasty in Nonagenarians - A National In-Patient Sample-Based Study of Perioperative Complications. Geriatr Orthop Surg Rehabil 2023; 14:21514593231178624. [PMID: 37250017 PMCID: PMC10214100 DOI: 10.1177/21514593231178624] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/28/2022] [Revised: 05/08/2023] [Accepted: 05/11/2023] [Indexed: 05/31/2023] Open
Abstract
Background Nonagenarians are a rapidly expanding population in the United States. These patients are met with increasing rates of hip arthritis, necessitating the need for total hip arthroplasty (THA). However, there is currently limited information on hospitalization information and perioperative complications in this population. Methods: In this retrospective study, we used the Nationwide Inpatient Sample (NIS) database from 2016-2019 to analyze the incidence of perioperative complications, length of stay (LOS), and the cost of care (COC) among patients undergoing THAs who were categorized as nonagenarians, and those who were not. Results The NIS database identified 309 100 patients who underwent THAs from 2016-2019. Of those, 1864 patients (.6%) were nonagenarian, while the remaining 307 236 patients were included under the non-nonagenarian category (control). The mean age in the nonagenarian group was 90 years compared to the control group which had a mean age of 65.8 years. There was an increased incidence of mortality rate (nonagenarian group .2%, control group .03%, P < .001), myocardial infarction (MI) (nonagenarian group .1%, control group .02%, P = .01), acute renal failure (ARF) (nonagenarian group 5.4%, control group 1.6%, P < .001), blood anemia post-operatively (nonagenarian group 28.9%, control group 17.2%, P < .001), and deep vein thrombosis (DVT) (nonagenarian group .48%, control group .07%, P < .001) in the nonagenarian group. The COC for the nonagenarian group was higher than that in the control group (P < .001). The mean LOS was longer in the nonagenarian group (3.1 days) in comparison to the control group (1.96 days) (P < .001). Conclusions Nonagenarians had significantly higher rates of both orthopedics and medical complications than the younger patients undergoing THAs. In addition, the nonagenarian group incurred higher COC. This information is useful for the providers to make informed decisions regarding patient care and resource utilization for nonagenarian patients undergoing THAs.

Analysis of inpatient complications in HIV/AIDS patients undergoing total hip arthroplasty - A propensity matched cohort study. J Clin Orthop Trauma 2023; 40:102168. [PMID: 37250618 PMCID: PMC10209670 DOI: 10.1016/j.jcot.2023.102168] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/04/2022] [Revised: 04/04/2023] [Accepted: 05/11/2023] [Indexed: 05/31/2023] Open
Abstract
Patients with human immunodeficiency virus (HIV) are at higher risk for orthopedic related diseases due to dysregulation in bone metabolism and metabolic effects related to their medication regimen. Furthermore, the rate of hip arthroplasty in HIV patients is increasing. With the recent changes in THA methodologies and improvements in HIV treatment, there is a need for updated research analyzing hip arthroplasty outcomes in this high-risk patient population. In this study, we used a national database to evaluate postoperative outcomes in HIV patients undergoing THA compared to THA patients without HIV. We use a propensity algorithm to create a cohort of 493 HIV negative patients for matched analysis. Among the 367,894 THA patients included in this study, 367,390 patients were HIV negative and 504 were HIV positive. The HIV cohort had a lower mean age (53.34 vs 65.88, p < 0.001), lower proportion of females (44% vs 76.4%, p < 0.001), lower incidence of diabetes without complications (5% vs 11.1%, p < 0.001) and a lower incidence of obesity (0.544 vs 0.875, p = 0.002). In the unmatched analysis, the incidence of acute kidney injury (4.8% vs 2.5%, p = 0.004), pneumonia (1.2% vs 0.2%, p = 0.002), periprosthetic infection (3.6% vs 1%, p < 0.001), and wound dehiscence (0.6% vs 0.1%, p = 0.009) were higher in HIV cohort, most likely due to inherent demographic variances present in the HIV population. In the matched analysis, the rates of blood transfusion (5.0% vs 8.3%, p = 0.041) were lower in the HIV cohort. Other post-operative variables, such as rates of pneumonia, wound dehiscence, and surgical site infections were not statistically significant between the HIV positive population and HIV negative matched cohort. Our study found similar rates of postoperative complications in HIV positive and HIV negative patients. The rate of blood transfusions in HIV positive patients was also noted to be lower. Our data suggests that THA is a safe procedure in patients infected with HIV.

Abstract
INTRODUCTION Patients with spinal cord injury (SCI) with degenerative joint disease of the knee may require total knee arthroplasty (TKA). This study examines the demographic and immediate postoperative outcomes of patients with SCI who undergo TKA. METHODS Admissions data for TKA and SCI were analyzed from the National Inpatient Sample database using International Classification of Diseases, 10th Revision, Clinical Modification diagnosis codes. An extensive array of preoperative and postoperative variables was compared among SCI TKA patients and non-SCI TKA patients. An unmatched and matched analysis using a 1:1 propensity match algorithm was conducted to compare the two groups. RESULTS Patients with SCI tend to be younger and have a 7.518 times greater risk of acute renal failure, 2.3 times greater risk of blood loss, and higher risk of local complications, including periprosthetic fracture and prosthetic infection. The average length of stay in the SCI cohort was 2.12 times greater, with a 1.58 times higher mean total incurred charge than the non-SCI group. CONCLUSION SCI is associated with an increased risk of acute renal failure, blood loss anemia, periprosthetic fractures and infections, a longer length of stay, and greater incurred charges in TKA patients.

How does systemic lupus erythematosus impact the peri-operative complication rates in primary hip arthroplasty? A national inpatient sample-based study. Arch Orthop Trauma Surg 2023; 143:2209-2216. [PMID: 35643817 DOI: 10.1007/s00402-022-04475-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/06/2022] [Accepted: 05/05/2022] [Indexed: 02/09/2023]
Abstract
INTRODUCTION With prolonged life expectancy, the number of patients with systemic lupus erythematosus (SLE) undergoing total hip arthroplasty (THA) has substantially increased over the past years. The post-operative outcome and complications in SLE are less clearly understood than other inflammatory diseases, due to limited availability of evidence within the literature. METHODS Using the National Inpatient Sample (NIS) database, patients who underwent THA between 2016 and 2019 were identified (ICD-10 CMP code). Patients were then classified into one of the two groups, namely those with SLE (ICD-10-CM; code710.0) or those without SLE (NSLE). Data regarding demographic details, co-morbidities, details regarding hospital stay, expenditure incurred, and complications encountered were analyzed, and compared between the groups. RESULTS Overall, among 367,894 patients undergoing THA, 1684 (0.5%) had SLE. Mean age of SLE (57.3 ± 14.5 years) patients undergoing THA was significantly lower than NSLE (65.9 ± 11.4 years) population (p = 0.001). There was a greater proportion of female patients in SLE group [89.6% (SLE) vs 55.8% (NSLE); p = 0.001]. SLE patients had a greater incidence of emergent hospital admissions (p = 0.04), longer hospital stay (p = 0.001), and higher hospital-related expenditure (p = 0.001). Among the peri-operative complications, SLE patients had significantly greater risk of developing post-operative anemia (p = 0.001), need for blood transfusion (p = 0.001), peri-prosthetic mechanical complications (p = 0.04), and prosthetic dislocations (p = 0.001). There was also a greater incidence of peri-prosthetic infections in the SLE group (p = 0.001). CONCLUSION The presence of SLE significantly lengthens hospital stay and augments healthcare-related costs in patients undergoing THA. The three main complications which may significantly affect the post-operative course of these patients include higher rates of post-operative anemia, peri-prosthetic infections, and early prosthetic dislocations.

Ankylosing spondylitis substantially increases health-care costs and length of hospital stay following total hip arthroplasty - National in-patient database study. J Clin Orthop Trauma 2023; 39:102151. [PMID: 37123430 PMCID: PMC10130334 DOI: 10.1016/j.jcot.2023.102151] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/01/2022] [Accepted: 03/31/2023] [Indexed: 05/02/2023] Open
Abstract
Introduction The outcome following major arthroplasty surgeries in patients with ankylosing spondylitis (AS) has tremendously improved over the past decades, due to substantial amelioration in the medical therapies and sophistication of available surgical modalities. Although various studies have already demonstrated the complication rates and challenges faced in AS patients undergoing THA, there is a substantial paucity of data on the actual healthcare burden associated with this disease, and the diverse factors which may affect it. Methods Using the National Inpatient Sample (NIS) database (on the basis of ICD-10 CMP codes), patients undergoing THA between the years 2016 and 2019 were identified. These patients were then classified into two categories: group A: patients with a known diagnosis of AS; and group N: those without. The details regarding demographical information, associated co-morbidities, data pertaining to patients' hospital admissions including expenditure incurred, length of stay and complications encountered, were compared. In addition, propensity-score matching was performed to identify a 1:1 matched sample of THA patients without AS. Results Overall, 367,890 patients underwent THA; among whom, 501 (0.14%) were known AS patients (group A). Group A included a substantially higher proportion of patients belonging to younger age group (58.6 ± 13.4 versus 65.9 ± 11.4 years; p < 0.001), male sex (67.1% in group A vs 44.1% in group N; p < 0.001), and Asian ethnicity (p < 0.001). Group A patients had a substantially higher risk for longer duration of hospital stay (p < 0.03) and higher overall healthcare expenditure incurred (p < 0.001). As compared to group N, AS patients had a significantly higher risk for developing post-operative anemia [21.8% (group A) vs 11.8% (group N); p < 0.02]; and higher rate of periprosthetic infections [2.4% (group A) vs 1.0% (group N); p < 0.007]. Conclusion Patients with AS require a significantly longer duration of hospital stay and higher admission-related expenditure following THA, as compared to the general population. These enhanced early health care-associated costs can be attributed to higher complication rates in AS patients. AS patients are prone to higher rates of anemia and peri-prosthetic infections during the early post-THA period.

Analysis of Baseline Characteristics, Length of Stay, Cost of Care, Complications and Subgroup Analysis of Patients Undergoing Total Ankle Arthroplasty-A Large Database Study. J Foot Ankle Surg 2023; 62:310-316. [PMID: 36163143 DOI: 10.1053/j.jfas.2022.08.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/04/2022] [Revised: 07/26/2022] [Accepted: 08/13/2022] [Indexed: 02/03/2023]
Abstract
Although total ankle arthroplasty (TAA) is becoming a progressively common procedure with a reported 10-fold increase in its prevalence over the past 2 decades; there is still limited large-scale data regarding its overall outcome. Using the National Inpatient Sample (NIS) database, patients who underwent TAA between 2016 and 2019 were identified (ICD-10 CMP code). Data regarding demographic details, co-morbidities, geographic locations of procedure, hospital stay, expenditure incurred, and complications encountered were analyzed. Additionally, a comprehensive subgroup analysis was performed to evaluate the impact of multiple preoperative variables (including gender, diabetes, obesity, CKD and tobacco abuse) on the patient outcome. Overall, 5087 patients (mean age: 65.1 years, 54% males, 85% Caucasians, 75% from large metropolitan regions) underwent TAA. Eighty eight percent of patients were discharged to home; and the mean length of hospital stay and hospital-related expenditure were 1.7 ± 1.41 days and $92,304.5 ± 50,794.1, respectively. The overall complication rate was 8.39% {commonest medical complications: anemia [131 (2.6%) patients) and acute renal failure [37 (0.7%) patients]; commonest local complication: periprosthetic mechanical adversities [90 (1.7%) patients]}. Female and CKD patients demonstrated significantly higher risks of medical (female: p = .003; CKD: p < .001) and surgical (female: p = .005; CKD: p < .019) complications; while obesity substantially enhanced the risk of medical adversities (p < .001). Based on our study, we could conclude that the rates of TAA in the United States are on the rise, especially in regions with population greater than 250,000. TAA is a safe procedure with relatively low complication rates. The complications and hospital-associated expenditure seem to vary between different patient subgroups.

Abstract
Background Parkinson's Disease is a well-known neuromuscular disorder, which affects the stability and gait of elderly patients. With the progressive increase in the life span of patients with PD, the problem of degenerative arthritis and the consequent need for total hip arthroplasty (THA) in this cohort are rising. There is paucity of data in the existing literature regarding the healthcare costs and overall outcome following THA in PD patients. The current study was planned to assess the hospital expenditure, details regarding hospital stay, and complication rates for patients with PD, who underwent THA. Methods We investigated the National Inpatient Sample data to identify PD patients, who underwent hip arthroplasty from 2016 to 2019. Using propensity score, PD patients were matched 1:1 to patients without PD by age, gender, non-elective admission, tobacco use, diabetes, and obesity. Chi-square and T-tests were used for analyzing categorical and non-categorical variables, respectively (Fischer-Exact test was employed for values<5). Results Overall, 367,890 (1927 patients with PD) THAs were performed between 2016 and 2019. Before matching, PD group had significantly greater proportion of older patients, males, and non-elective admissions for THA (P<0.001). After matching, PD group had higher total hospital costs, longer hospital stay, greater blood loss anemia, and prosthetic dislocation (P<0.001). The in-hospital mortality was similar between the two groups. Conclusion Patients with PD undergoing THA required greater proportion of emergent hospital admissions. Based on our study, the diagnosis of PD showed significant association with greater cost of care, longer hospital stay, and higher post-operative complications.

Dialysis Patients Undergoing Total Hip Arthroplasty have Higher Rates of Morbidity and Mortality and Incur Greater Healthcare Costs: A National Database Study from 367,894 Patients. Indian J Orthop 2023; 57:336-343. [PMID: 36777113 PMCID: PMC9880083 DOI: 10.1007/s43465-022-00799-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/24/2022] [Accepted: 12/08/2022] [Indexed: 12/24/2022]
Abstract
Purpose The incidence of a total hip arthroplasty (THA) is sevenfold higher in dialysed patients. Only a few have specifically studied the impact of chronic dialysis on outcomes of THA whilst comparing them with non-dialysed/controls. The present study questioned whether significant differences existed in morbidity and mortality rates after THA in dialysed and non-dialysed patients. Methods The National Inpatient Sample (NIS) database Healthcare Cost and Utilization Project using records for THAs performed during 2016-2019 was employed. This largest, nationwide, in-patient database in the US acquires data from > 7 million hospital stays annually from > 20% hospitals. Among 367,894 THAs performed during 2016-2019, 383 were regularly dialysed. The two groups (dialysis and controls) were compared for in-hospital mortality, demographic data, perioperative details and medical/surgical complications. Results Dialysed patients were younger (p < 0.001), had greater mortality (0.5% vs 0.09%, p = 0.005), lengths of stay (4.4 vs 2.3 days, p < 0.001), costs ($96,824 vs $66,848, p < 0.001) and male preponderance (p < 0.001). Postoperative dislocations (3.1% vs 1.4%, p = 0.013), mechanical complications (p = 0.032) and blood loss (p = 0.031) were greater in dialysed patients. Medical postoperative complications (myocardial infarction, pneumonia, thromboembolism, acute renal failure), periprosthetic fractures, wound dehiscence, superficial and deep surgical-site infection and periprosthetic joint infections were comparable between the 2 groups. Dialysed patients had elective THAs more often (25% vs 8.6%). Controls had higher (twofold) home discharges while ~ 50% of dialysed THAs needed discharge to another facility. Conclusions This large national data highlighted greater morbidity and mortality among dialysis patients following THA, something to consider preoperatively along with individual circumstances whilst making risk-benefit assessments for arthroplasty. Improvements in healthcare could bridge gaps between outcomes and expectations in dialysed patients.

Abstract
BACKGROUND Femoral intramedullary nailing is traditionally performed with the patient supine on a fracture table. We aimed to describe a case series of femoral intramedullary nailing for fracture in the lateral position, with discussion of the operative technique. METHODS A retrospective analysis identified 52 patients who underwent femoral intramedullary nailing performed in a lateral position without traction over a 5-year period at a single level 1 trauma center. Medical records were reviewed for demographics, blood loss including need for transfusion, operative duration, complications, length of stay, fracture union, re-operation and death. RESULTS There were 24 subtrochanteric, 16 peri-trochanteric and 12 diaphyseal femoral fractures. Mean operative time was 136.2 ± 101.4 min with a mean estimated blood loss of 372.5 ± 349.6 ml. Seventeen patients required blood transfusion. Mean length of stay was 10.3 ± 8.1 days. There were 3 (5.8%) surgical (compartment syndrome, infection and retained drain) and 12 (23.1%) medical complications, with a 30-day mortality rate of 3.8% (2). Mean follow-up was 9.9 ± 8.7 months. The union rate was 94.2% (49) and 3.8% (2) patients required revision fixation (hardware exchange for irritation and exchange nailing for non-union). Discharge destination was home, rehabilitation center and specialized nursing facility in 21 (40.4%), 16 (30.8%) and 15 (28.8%) patients, respectively. DISCUSSION AND CONCLUSION Femoral intramedullary nailing in the lateral decubitus position is a useful technique of managing peri-trochanteric, subtrochanteric and diaphyseal femoral fractures. We describe a known technique with technical tips, which has distinct advantages over traditional supine positioning especially in certain patient and fracture types. In addition, operative times, blood loss, length of stay, revision and outcomes were comparable to the literature.

How does sickle cell disease affect the peri-operative outcome in patients undergoing total knee arthroplasty? A large-scale, National Inpatient Sample-based study. Arch Orthop Trauma Surg 2023:10.1007/s00402-022-04762-1. [PMID: 36592196 DOI: 10.1007/s00402-022-04762-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/22/2022] [Accepted: 12/28/2022] [Indexed: 01/03/2023]
Abstract
INTRODUCTION In view of the vaso-occlusive pathophysiology affecting osseous micro-circulation, sickle cell disease (SCD) is well known to present with diverse skeletal and arthritic manifestations. With prolonged life-expectancy over the past decades, there has been a progressive increase in the proportion of SCD patients requiring joint reconstructions. Owing to the paucity of evidence in the literature, the post-operative complication rates and outcome in these patients following total knee arthroplasty (TKA) are still largely unknown. METHODS Based on the National Inpatient Sample (NIS) database (using ICD-10 CMP code), patients who underwent TKA between 2016 and 2019 were identified. The cohort were classified into two groups: A-those with SCD; and B-those without. The data on patients' demographics, co-morbidities, details regarding hospital stay including expenditure incurred, and complications were analyzed and compared. RESULTS Overall, 558,361 patients underwent unilateral, primary TKA; among whom, 493 (0.1%) were known cases of SCD (group A). Group A included a significantly greater proportion of younger (60.14 ± 10.87 vs 66.72 ± 9.50 years; p < 0.001), male (77.3 vs 61.5%; p < 0.001); and African-American (88.2 vs 8.3%B; p < 0.001) patients, in comparison with group B. Group A patients were also at a significantly higher risk for longer duration of peri-operative hospital stay (p < 0.001), greater health-care costs incurred (p < 0.001), and greater need for alternative step-down health-care facilities (p < 0.001) following discharge. Among the SCD patients, 24.7%, 20.9% and 24.9% developed acute chest syndrome, pain crisis and splenic sequestration crisis, respectively during the peri-operative period. Group A patients had a statistically greater incidence of acute renal failure (ARF; p = 0.014), need for blood transfusion (p < 0.001) and deep vein thrombosis (DVT; p = 0.03) during the early admission period. CONCLUSION The presence of SCD substantially lengthens the duration of hospital stay and enhances health care-associated expenditure in patients undergoing TKA. SCD patients are at significantly higher risk for systemic complications including acute chest syndrome, pain crisis, splenic sequestration crisis, acute renal failure, higher need for blood transfusions and deep venous thrombosis during the initial peri-operative period following TKA.

Uncemented Hemiarthroplasty in Displaced Femoral Neck Fractures is associated with Higher Perioperative Surgical Complications but Lower Medical Complications: Analysis from the National Inpatient Database. THE ARCHIVES OF BONE AND JOINT SURGERY 2023; 11:582-587. [PMID: 37868136 PMCID: PMC10585485 DOI: 10.22038/abjs.2023.70498.3307] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Received: 02/10/2023] [Accepted: 07/20/2023] [Indexed: 10/24/2023]
Abstract
Objectives This study aimed to analyze and compare the perioperative outcomes of cemented and uncemented hemiarthroplasty in elderly patients with displaced femoral neck fractures by utilizing the data from the National Inpatient Sample database. Methods Data from the National Inpatient Sample Database was analyzed to identify patients who underwent hemiarthroplasty following a displaced femoral neck fracture (cemented and uncemented. Demographic data, comorbidities, length of stay, total charges, and perioperative complications were analyzed. Results 27390 patients were identified in the cemented group and 29406 in the uncemented group. The patients who underwent uncemented hemiarthroplasty demonstrated a higher incidence of prosthetic dislocation (Odds Ratio (OR) 3.348, p < 0.001), periprosthetic mechanical complications (OR 2.597, p < 0.001), wound dehiscence (OR 2.883, p < 0.001), superficial surgical site infection (OR 2.396, p = 0.043), deep surgical site infection (OR 1.686, p < 0.001), and periprosthetic fractures (OR 2.292, p < 0.001) as compared with patients who underwent cemented hemiarthroplasty. However, patients with uncemented fixation demonstrated a lower incidence of death (OR 0.567, p < 0.001), pulmonary embolism (OR 0.565, p < 0.001), deep vein thrombosis (DVT) (OR 0.746, p < 0.001), myocardial infarction (OR 0.772, p = 0.025) and blood loss anemia (OR 0.869, p < 0.001) as compared with cemented fixation. Conclusion Our study on displaced femoral neck fractures utilizing the National Inpatient database found that uncemented hemiarthroplasty was associated with a higher incidence of perioperative surgical complications. Cemented hemiarthroplasty, however, was associated with a statistically significant higher rate of death, pulmonary embolism, deep vein thrombosis, and myocardial infarction.

HIV/AIDS patients undergoing total knee arthroplasty are at higher risk of acute renal failure and transfusion and incurred higher cost: a propensity-matched database study. Knee Surg Relat Res 2022; 34:28. [PMID: 35706063 PMCID: PMC9202157 DOI: 10.1186/s43019-022-00156-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/14/2022] [Accepted: 05/20/2022] [Indexed: 11/10/2022] Open
Abstract
Introduction Human immunodeficiency virus (HIV) is a retrovirus that can cause acquired immunodeficiency syndrome (AIDS). Total knee arthroplasty (TKA) in HIV-positive patients has not been well documented in the current literature. Thus, this study aimed to examine the early postoperative outcomes and complications of HIV-positive TKA patients as compared to TKA patients who are HIV-negative patients by utilizing the National Inpatient Sample (NIS) database. Methods Admissions data for TKA and HIV were analyzed from the NIS database using ICD-10-CM diagnosis codes. An extensive array of preoperative and postoperative variables was compared among HIV positive TKA patients and HIV negative TKA patients. An unmatched analysis and a matched analysis using a 1:1 propensity match algorithm were conducted to compare the two groups. Results The average age of the HIV-positive group was lower than the HIV-negative group (59.0 vs 66.7, p < 0.001). The HIV-positive group had a smaller percentage of females (38.4% vs 61.5%, p < 0.001) and a lower incidence of tobacco-related disorders than the HIV-negative group (10.3% vs 15.8%, p = 0.032). The HIV-positive group had a longer mean length of stay (3.0 days vs 2.4 days, p < 0.001) and a greater mean total charge incurred (90,780.25 vs 64,801.55, p < 0.001). In the unmatched analysis, the incidence of acute renal failure (6.4% vs 2%, p < 0.001), transfusions (3.9% vs 1.5%, p = 0.004), and periprosthetic joint infection (3% vs 1%, p = 0.007) was higher in HIV positive group. The matched analysis showed a higher incidence of acute renal failure group (6.4% vs 0.5%, p = 0.01) and transfusions (3.9% vs 5%, p = 0.01) in the HIV-positive but a statistically insignificant difference in the rate of periprosthetic joint infection (3% vs 1%, p = 0.153). Conclusion HIV/AIDS is associated with an increased incidence of acute renal failure and transfusions, as well as a longer length of stay and higher incurred costs in TKA patients.

Abstract
Background The purpose of this study was to analyze the post-operative complications following THA in organ transplant patients; and compare the outcome with general population undergoing THA. Methods and materials In this retrospective study using the National Inpatient Sample (NIS) database, 813 cases of THA (both primary and revision THA) in organ transplant patients (OT) were reviewed. ICD-10 codes were used to assess post-operative variables including the length of stay, cost of care, medical and surgical complications among OT patients undergoing THA. A comparison of all these variables was made with the non-OT (NOT) control population. Results Among 367,894 patients undergoing THR between 2016 and 2019 on NIS database, 813 were OT patients. There was significantly greater proportion of males in the OT group (p < 0.001). Patients in the OT group were also significantly younger (mean age: 61.08 ± 11.95 in OT versus 65.87 ± 11.39 years in NOT; p < 0.001). The OT group had significantly higher prevalence of anemia (p < 0.001), acute renal failure (ARF; p < 0.001), and transfusion rates (p < 0.001). The OT patients also had significantly greater dislocation rates (p = 0.010), wound dehiscence (p = 0.03) and deep surgical-site infections (SSI; p = 0.002). The mean length of hospital stay (3.55 ± 4.89 days in OT vs 2.32 ± 2.52 days in NOT; p < 0.001), cost of care ($82,567.89 ± 74,505.54 vs $66,845.18 ± 47,761.39 for OT and NOT groups, respectively; p < 0.001) and mortality (p = 0.04) were significantly greater in the OT population, as compared to controls. Conclusion Organ transplant patients have significantly greater risk for developing post-operative complications like anemia, ARF, need for higher transfusion rates, prosthetic dislocations, wound dehiscence, and deep SSI following THA. The length of stay, total expenditure incurred and mortality were also higher in OT patients undergoing THA.

Comparison of Differences in Complications and Revision After Conversion to Total Hip Arthroplasty from Plating vs. Nailing vs. Hemiarthroplasty. THE ARCHIVES OF BONE AND JOINT SURGERY 2022; 10:785-790. [PMID: 36246028 PMCID: PMC9527430 DOI: 10.22038/abjs.2021.60893.3000] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Received: 11/07/2021] [Accepted: 12/13/2021] [Indexed: 01/24/2023]
Abstract
BACKGROUND Total hip arthroplasty (THA)after previous hip surgery increases the procedure complexity and complication rate. We investigated the complication rates following conversion to total hip arthroplasty from three hip surgeries, namely plate fixation of the intertrochanteric fracture, nailing of the trochanteric fracture, and hemiarthroplasty of the hip. METHODS This retrospective study was conducted using the PearlDiver database (www.pearldiverinc.com, Colorado Springs) and identified all patients undergoing THA between 2010 and 2019. Among this group, we included all patients who had received one of the three procedures , hip hemiarthroplasty (CPT 27125), fixation of the intertrochanteric fracture with plates and screws (CPT 27444), or fixation of hip fracture with nail (CPT 27445) within two years of THA. We analyzed complications in these patients and compared it to the complication rate in primary THA patients. The complications analyzed were 30-day transfusion risk, 90-day surgical site infection (SSI) risk, 90-day periprosthetic fracture risk, 1-year dislocation risk, and 2-, 5-, and 10-year revision risk. RESULTS A total of 118,209 patients underwent THA between 2010 and 2019. A total of 9,173, 48,326, and 31,632 patients underwent fixation with plates and screws , nailing and hemiarthroplasty respectively. We identified 71, 42, and 160 patients with hemiarthroplasty, plates & screws, and nailing, respectively, within two years of THA. 117,936 primary THA patients were used as a comparison group. The nailing group had the highest rate of transfusion risk (OR=2.34, 95% CI=1.32, 4.13, P<0.05).Furthermore, the hemiarthroplasty group had highest rate of SSI risk (OR=9.25, 95% CI=4.86, 17.63, P<0.05) and highest revision risk at 2 years (OR=10.532, 95% CI= 6.09, 18.19, P<0.05). CONCLUSION Conversion of hemiarthroplasty to THA was associated with a higher risk of infection and revision. Hence, surgeons considering primary hip hemiarthroplasty for severely comminuted intertrochanteric fracture should exercise caution, especially for active elderly patients.

Conversion Total Knee Arthroplasty After Tibial Plateau Fixation Is Associated With Lower Reimbursement, Greater Complication Rates, and Similar Opioid Use. Cureus 2022; 14:e25171. [PMID: 35747060 PMCID: PMC9206867 DOI: 10.7759/cureus.25171] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 05/20/2022] [Indexed: 11/20/2022] Open
Abstract
Objective Total knee replacement after previous open reduction and internal fixation for tibial plateau fracture (conversion total knee) increases the complexity of the procedure and the complication rate. However, very little research exists to report on opioid use and cost associated with total knee arthroplasty (TKA) following tibial plateau fracture fixation as compared to primary TKA patients with no history of tibial plateau fracture. The aim of this study is to compare the differences in opioid use, reimbursements, and complication rates between patients with and without a history of tibial plateau fracture undergoing TKA. Methods and materials This is a retrospective large database review study. The study included patients across the country and in various clinical settings including, but not limited to, institutions, primary and tertiary care centers, and private practice. The PearlDiver database was reviewed for patients undergoing TKA between 2010 and 2019. Patients who underwent TKA following surgical repair of a tibial plateau fracture were identified using Common Procedural Terminology (CPT) codes and the appropriate International Classification of Diseases Ninth and Tenth Revision (ICD-9, ICD-10) codes. This group was then matched by age, gender, Charleston Comorbidity Index (CCI) score, Elixhauser Comorbidity Index (ECI) score, obesity, tobacco use, and diabetes to a group of similar patients who underwent TKA with no history of tibial plateau fracture. Opioid use over the episode of care, evaluated by morphine milligram equivalents (MME), and 30-day reimbursed cost were compared between groups using an unequal variance t-test. Complication rates at 30 days, 90 days, and one year postoperatively, and revision rates at one and two years postoperatively were compared using the odd’s ratio (OR) with 95% confidence intervals (95%CI). Results The episode of care cost for TKA was significantly lower for patients with a history of tibial plateau fracture ($11,615 ± $15,704) than it was for patients without a history of tibial plateau fracture ($16,088 ± $18,573) (p = 3.56E-14). At 30 days after knee arthroplasty, patients with a history of tibial plateau fracture had significantly more episodes of dehiscence (OR 2.665 [95% CI 1.327-5.351]; p = 0.006) and surgical site infection (SSI) (OR 1.698 [95% CI 1.058-2.724]; p = 0.028), which was significant at 90 days postop for both dehiscence (OR 1.358 [95% CI 0.723-2.551]; p = 0.001) and SSI (OR 1.634 [95% CI 1.100-1.802]; p = 0.015), as well as mechanical complications of the implant device (OR 2.420 [95% CI 1.154-5.076]; p = 0.019). There was no significant difference in the number of opioids prescribed postoperatively to patients with a history of tibial plateau fracture (2218 ± 3255 MME) compared to those without prior tibial plateau fracture (2400 ± 4843 MME) (p = 0.258). However, there was a small but statistically significant increase in the number of days postoperatively patients with a history of tibial plateau fracture were prescribed opioids (11.99 ± 7.73 days) compared to non-tibial plateau fracture patients (11.15 ± 7.18 days) (p = 0.004). Conclusion Patients with a history of tibial plateau fracture who then underwent conversion TKA have a lower reimbursed cost of TKA but a higher postoperative risk for dehiscence, mechanical complications, and surgical site infections. There is no significant difference in postoperative opioid use between the two groups.

Abstract
BACKGROUND As the prevalence of Total Knee Arthroplasty increases, there is still debate over the preferred method of treatment of supracondylar periprosthetic femoral fractures. The aim of this study was to compare two of the common methods of fixation: Locked Plating and Retrograde Intramedullary Nailing with respect to nonunion, delayed union and surgical revision rate. METHODS A comprehensive database search via Pubmed was conducted, yielding 16 eligible studies. Six of those studies were comparative and were used in the meta-analysis section. All 16 studies were used in the pooled sample analysis section. The primary outcome analyzed was nonunion and delayed union rate while the secondary outcome was the surgical revision rate. Odds ratios (ORs) and corresponding 95% confidence intervals (CIs) were calculated by comparing incidences of nonunion and delayed union, and surgical revision rates among the studies. RESULTS The meta-analysis showed that there is no statistically significant difference among the two groups in terms of nonunion and delayed union rate (OR = 1.43, CI = 0.74, 2.74, P=0.28), but there is a significant difference in the surgical revision rate favoring locked plating over retrograde intramedullary nailing (OR = 2.71, CI = 1.42, 5.17, P=0.003). The pooled sample analysis showed that there is no significant difference in the nonunion and delayed union rates (P=0.210) or the surgical revision rates (P=0.038). CONCLUSION Both locked plating and Retrograde Intramedullary Nailing are reliable options for treating supracondylar femoral fractures around Total Knee Arthroplasty. Locked plating demonstrated a trend towards decreased nonunion and delayed union rates and a significantly lower surgical revision rate in the meta-analysis.

Abstract
Background: Total knee arthroplasty (TKA) is a very common orthopedic procedure and with legalization of cannabis in many states, orthopedic surgeons are frequently encountering patients undergoing TKA with preoperative cannabis use disorder. There is conflicting and limited evidence on the impact of preoperative cannabis use and postoperative outcome. Methods and materials: In this study we retrospectively reviewed PearlDiver insurance database and analyzed the characteristics of the cannabis use in TKA patients and the impact of preoperative diagnosis of cannabis use disorder on postoperative risk of manipulation under anesthesia (MUA) within one year and revision risk within two years. We compared our results to a matched sample of opioid use patients and standard TKA patients. Result: Our study shows that cannabis use disorder was found in less than 1% of the patients undergoing total knee replacement. We identified 278 patients with cannabis use disorder undergoing TKA. More than 90% of the patients are between 40 to 69 years. There was no statistically significant gender difference noted with 130 males and 148 females. Matching sample analysis showed that the risk of MUA and risk of revision in these cannabis use patients are comparable to standard knee replacement patients and in TKA patients taking preoperative opioids. Conclusion: Retrospective database review failed to identify any increased risk of MUA or two-year revision in cannabis use TKA patients.

Intra-operative fractures in primary total knee arthroplasty - a systematic review. Knee Surg Relat Res 2020; 32:40. [PMID: 32778166 PMCID: PMC7419217 DOI: 10.1186/s43019-020-00054-3] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/23/2020] [Accepted: 06/23/2020] [Indexed: 02/08/2023] Open
Abstract
BACKGROUND One of the rare complications of primary total knee arthroplasty is intra-operative fracture. Intra-operative fracture during revision knee arthroplasty has been well-documented but there is limited literature on fractures occurring during primary knee arthroplasty. We conducted a systematic review of the literature to compare and contrast the various studies to clearly define the predisposing factors, incidence, and characteristics of the fracture itself and to arrive at a consensus on the management and prevention of intra-operative fractures during primary knee arthroplasty. METHODS The PubMed/Medline, Cochrane, Scopus and Embase databases were searched using keywords "intra-operative fracture", "distal femoral fracture", "tibial fracture", "patella fracture" and "primary total knee arthroplasty". A total of 158 articles were retrieved and after further filtration and exclusion processing, 10 articles that evaluated intra-operative fractures in primary total knee arthroplasty were included for the review. RESULTS The reported incidence of intra-operative fractures varied from 0.2% to 4.4%. A higher incidence in female patients with a male to female ratio of 0.4 was reported. Posterior stabilized (PS) total knee arthroplasty was associated with higher risk of intra-operative femoral fractures by many authors in this review. Timing of occurrence and location of the intra-operative fractures can vary widely, with femoral fractures occurring more commonly during bone preparation, trialing and impaction of the final implant and tibial fractures occurring during preparation for the tibial keel and impaction of the tibial component. CONCLUSIONS Intra-operative fractures during primary total knee arthroplasty are rare with higher risk associated with osteoporosis, rheumatoid arthritis, advanced age, female gender, chronic steroid use, metabolic bone disorders, PS type of femoral implant and difficult surgical exposure of the knee joint due to severe deformities. A plethora of management options have been utilized according to surgeon preference. Standard principles of fracture fixation and arthroplasty principles should be followed to achieve stable internal fixation and any unstable fracture site should be bypassed with the utilization of stemmed components. Satisfactory radiographic and functional outcome can be expected with appropriate treatment.

Abstract
Periprosthetic joint infection (PJI) is a catastrophic complication of total knee arthroplasty (TKA) adding significant costs to the health care system with increasing morbidity and mortality. The goal of this study was to develop a prognostic scoring system that could risk-stratify patients undergoing TKA for the risk of PJI. The study included 150 patients who underwent primary TKA from June 2012 to February2016. There were 60 patients in group I who were not risk stratified using the scoring system, while 90 patients were assigned to group II and were prospectively assigned scores based on the scoring system. Points were assigned for each pre-op variable and a scoring chart was developed. Group II patients scoring 4 or more were counseled to optimize their modifiable risk factors before proceeding with surgery. Retrospective chart review was done for patients in group I to find out their risk score for the study purpose. Nine out of 60 patients in group I were found to have score above 4 based on the chart review, of which 4 patients got infected (P<0.05). None of the group II patients got infected after TKA. In conclusion, our scoring system is an objective scoring system for preoperative risk stratification of patients undergoing TKA, thus helping identification and optimization of the risk factors preoperatively to decrease the risk of PJI.

Abstract
Calcifying Tendinitis (CT) shoulder a self limiting disorder characterized by deposition of calcium salts in rotator cuff muscles. The main symptom being pain followed by activity restriction resolving on its own in most cases. Symptomatic patients are initially managed by NSAIDs, Physiotherapy, Corticosteroid injections. ESWT involves acoustic waves causing fragmentation of deposits with pain releif. Ultrasound guided needling barbotage have shown promising results. Arthroscopic excision remains the definitive management for patients associated with complications as cuff tear and for uncomplicated patients. In calcifying tendinitis the initial evaluation, maintenance of function and appropriate choice of treatment modalities determines the prognosis.

Extra-articular deformities in arthritic knees-a grueling challenge for arthroplasty surgeons: An evidence-based update. Orthop Rev (Pavia) 2018; 9:7374. [PMID: 29564077 PMCID: PMC5850062 DOI: 10.4081/or.2017.7374] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/22/2017] [Revised: 12/09/2017] [Accepted: 12/10/2017] [Indexed: 12/21/2022] Open
Abstract
Critical to the success of a total knee arthroplasty (TKA) is the anatomical alignment. This may appear as a challenge in an extra-articular deformity (EAD) that may be inherent in certain people or result from fracture malunion, congenital disorders, nutritional, metabolic and infective causes. This appraisal aimed at providing the reader with an up-todate overview of the research carried out on, and existent evidence of EAD correction while planning a TKA. We reviewed the current English literature on TKA in extra-articular knee deformities. Among the published data, a common initial approach of mandatory clinical and radiological assessment emerges as an obligatory step while handling cases with EAD. While several methods of managing the deformity and arthritis have been described, a broad division into intra-articular and extra-articular means can be deciphered. The relatively old-school, yet reliable thought process of extra-articular correction allows an all-inclusive restoration of alignment with the inherent complications related to the necessary osteotomy. A cohort of younger and more venturesome surgeons seem inclined towards performing navigated, intra-articular correction for mild to moderate and sometimes, severe deformities. The crux of the matter lies is obtaining a well-balanced knee without violating the all-important cruciates. Restoring the patient’s ambulatory status seems sooner with the intra-articular methods which are also more precise in determining the axes and while removing minimum bone. Greatest satisfaction is accomplished in those with less grotesque, rotationallyaligned knees while meticulously balancing soft-tissues and encouraging earlier weightbearing.

Abstract
Tibial shaft fractures are one of the most common pediatric fractures. They require appropriate diagnosis and treatment to minimize complications and optimize outcomes. Diagnosis is clinical and radiological, which can be difficult in a young child or with minimal clinical findings. In addition to acute fracture, Toddler's and stress fractures are important entities. Child abuse must always be considered in a nonambulatory child presenting with an inconsistent history or suspicious concomitant injuries. Treatment is predominantly nonoperative with closed reduction and casting, requiring close clinical and radiological followup until union. Although there is potential for remodeling, this may not be adequate with more significant deformities, thus requiring remanipulation or rarely, operative intervention. This includes flexible intramedullary nailing, Kirschner wire fixation, external fixation, locked intramedullary nailing, and plating. Complications are uncommon but include deformity, growth arrest, nonunion, and compartment syndrome.

Total Knee Arthroplasty In Patients With Parkinson's Disease- A Critical Analysis of Available Evidence. Open Orthop J 2017; 11:1087-1093. [PMID: 29152001 PMCID: PMC5676002 DOI: 10.2174/1874325001711011087] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/20/2017] [Revised: 06/16/2017] [Accepted: 07/18/2017] [Indexed: 01/26/2023] Open
Abstract
Background: In this era of modern medicine, there is an increase in life expectancy and thereby an ageing population. Among this group one of the most common neurological disorder is Parkinson disease and one of the most common operation done in elderly population is a total joint arthroplasty. But total joint arthroplasty in Parkinson disease is a relatively uncommon entity. There is sparse literature available with regards to total knee arthroplasty (TKA) in Parkinson disease. This review focusses on the necessity, complications and previous experiences on TKA in PD based on the literature available. Method: The review was conducted after a series of advanced search in the following medical databases; Pub med, Biomed central, Cochrane and Google scholar for articles related to total knee replacement in patients with Parkinson’s disease. The following keywords were used; Total knee arthroplasty, Parkinson’s disease, Hoehn and Yahr, Flexion Contracture. Results: The review indicates that the functional outcome is comparable to that of controls in immediate post-operative phase, one year and three-year phase, but the long term functional outcome seems to deteriorate significantly. Conclusion: Total knee arthroplasty can serve as an effective tool in alleviating pain in short term as well as long term periods, whereas the functional outcome seems to deteriorate post operatively on a long-term basis. Nevertheless, TKA in PD is a challenging situation, thereby necessitating a holistic approach with the efforts from various specialists needed at each stage to ensure a successful operation.

Rationale of Cruciate Retaining Design in Rheumatoid Arthritis: A Review of Clinical Analysis and its Role in Rheumatoid Arthritis. Open Orthop J 2017; 11:1023-1027. [PMID: 29114338 PMCID: PMC5646171 DOI: 10.2174/1874325001711011023] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/27/2017] [Revised: 07/01/2017] [Accepted: 07/18/2017] [Indexed: 12/02/2022] Open
Abstract
Background: Over the years, proponents of total knee designs (cruciate retaining and posterior stabilised) have conducted several long-term
studies to claim the potential of these designs in several subsets of patients. Total knee arthroplasty (TKA)
in patients with rheumatoid arthritis has also been one such domain where numerous studies were conducted in the past.
A general perception among majority of arthroplasty surgeons is that, posterior stabilised (PS) is the implanted design
of choice among patients with Rheumatoid arthritis (RA). However, with the available literature there is a significant
disparity related to the selection of implants in patients with rheumatoid RA. In this review of literature, an attempt is made
to identify the clinical performance and role of one such implant design, the cruciate retaining (CR) prosthesis in rheumatoid arthritis. Method: The review was conducted after a series of advanced search in the following medical databases; Pub med, Biomed central, Cochrane
and Google scholar for articles related to long term follow up studies of cruciate retaining total knee arthroplasty in rheumatoid
arthritis using the keywords cruciate retaining prosthesis, total knee arthroplasty, rheumatoid arthritis. Results: The
available data demonstrate that the CR design is attributed with an excellent long term survivorship and functional outcome even in
follow up studies up to twenty-five years. Conclusion: The advantages of using a CR design are long term survivorship, controlled
femoral roll back and preservation of bone stock. Thus, the data gathered in this review lead to a consideration that the CR design is an implant
design on par with PS design in patients with RA.

Pre-discharge postoperative radiographs after primary total knee replacement : tradition or science? Acta Orthop Belg 2017; 83:132-139.

Abstract
Consistent evidence exists on the inutility of immediate postoperative radiographs after a total knee replacement (TKR). We hypothesized that eliminating the pre-discharge film would not have any effect on the postoperative patient outcomes. Retrospective analysis of prospectively collected data was performed on 220 knees. Patients undergoing a simple primary TKR operated by 2 surgeons (Surgeon A and B) from January 2013 to July 2015 were divided into 2 groups (Groups 1 and 2 having 112 and 108 knees respectively). While Surgeon A routinely asked for the second postoperative day pre-discharge radiograph, Surgeon B directly performed weight bearing radiographs 6 weeks postoperatively. Greater knee pain was seen in Group 1 (p = 0.01). No changes in rehabilitation protocols based on pre-discharge radiographs, complications, medico-legal issues or revision surgery could be identified in any patient. The quality of the pre-discharge radiographs was adequate in 65 of the 112 knees (58%). A cost reduction of approximately $220 per patient was observed with the exclusion of the pre-discharge film. Eliminating routine inpatient pre-discharge radio-graphs after simple primary TKR does not alter the rehabilitation protocol, identify any of the standard complication or have any medico-legal implications. On the contrary, these films seem to increase postoperative pain and costs.

Abstract
BACKGROUND Isolated tuberculous tenosynovitis and bursitis are rare among musculoske let al tuberculosis, but it is one of the major causes for chronic tendon sheath infection in developing countries. In hand, it is usually presented as a compound palmer ganglion (radio ulnar bursa), tenosynovitis of the flexer tendon sheaths and very few cases of tubercular tenosynovitis affecting the extensor tendons also are reported. CASE PRESENTATION We are reporting a rare case of tuberculous extensor tenosynovitis with rupture of the extensor digitorum tendon in an elderly Indian man. This case report and review meets the ethical standard of the journal. CONCLUSION Delayed diagnosis of tuberculous tenosynovitis is due to numerous differential diagnoses and slow progression. For all chronic synovitis around the wrist, consider Mycobacterial infection as an important differential diagnosis. Early diagnosis, radical excision combined with multidrug antituberculous therapy gives good functional results.

Abstract
Abscess formation following intramuscular injections is rare and they are most commonly seen in immunocompromised individuals. In this case series we present a cohort of three patients presented to us in a critically ill condition with an abscess due to intramuscular injection. Vancomycin resistant staphylococcus aureus was isolated from all three patients. These patients posed a major challenge to the healthcare system and the treating physician because of the: severity of illness, virulence and resistance of the organism, rarity of the situation, immune state of the patient, and lack of supporting evidence to properly guide management in the use of health resources. To the best of our knowledge, there is no report available in the English literature on vancomycin resistant staphylococcus aureus associated with intramuscular injection abscess.

A novel method of removal of a broken drill bit in the femoral medullary canal during internal fixation of a type C distal femoral fracture: a case report. Chin J Traumatol 2016; 15:315-6.

Abstract
Breakage of surgical instruments and implants during operative procedures is not uncommon in any surgical discipline. The need for removal and the outcome of leaving the broken instruments and implants in the surgical area have not been described in detail. Few studies have suggested removal if they are lying loosely in the tissues or joint, close to neurovascular structures. Challenges and the amount of time spent in the retrieval of broken instruments and implants are well known among surgeons, so most choose to leave them in situ. We reported a novel method of retrieval of a broken drill bit in the femoral medullary canal during internal fixation of a type C distal femoral fracture.

Rotator cuff tears: An evidence based approach. World J Orthop 2015; 6:902-918.

Abstract
Lesions of the rotator cuff (RC) are a common occurrence affecting millions of people across all parts of the globe. RC tears are also rampantly prevalent with an age-dependent increase in numbers. Other associated factors include a history of trauma, limb dominance, contralateral shoulder, smoking-status, hypercholesterolemia, posture and occupational dispositions. The challenge lies in early diagnosis since a high proportion of patients are asymptomatic. Pain and decreasing shoulder power and function should alert the heedful practitioner in recognizing promptly the onset or aggravation of existing RC tears. Partial-thickness tears (PTT) can be bursal-sided or articular-sided tears. Over the course of time, PTT enlarge and propagate into full-thickness tears (FTT) and develop distinct chronic pathological changes due to muscle retraction, fatty infiltration and muscle atrophy. These lead to a reduction in tendon elasticity and viability. Eventually, the glenohumeral joint experiences a series of degenerative alterations - cuff tear arthropathy. To avert this, a vigilant clinician must utilize and corroborate clinical skill and radiological findings to identify tear progression. Modern radio-diagnostic means of ultrasonography and magnetic resonance imaging provide excellent visualization of structural details and are crucial in determining further course of action for these patients. Physical therapy along with activity modifications, anti-inflammatory and analgesic medications form the pillars of nonoperative treatment. Elderly patients with minimal functional demands can be managed conservatively and reassessed at frequent intervals. Regular monitoring helps in isolating patients who require surgical interventions. Early surgery should be considered in younger, active and symptomatic, healthy patients. In addition to being cost-effective, this helps in providing a functional shoulder with a stable cuff. An easily reproducible technique of maximal strength and sturdiness should by chosen among the armamentarium of the shoulder surgeon. Grade 1 PTTs do well with debridement while more severe lesions mandate repair either by trans-tendon technique or repair following conversion into FTT. Early repair of repairable FTT can avoid appearance and progression of disability and weakness. The choice of surgery varies from surgeon-to-surgeon with arthroscopy taking the lead in the current scenario. The double-row repairs have an edge over the single-row technique in some patients especially those with massive tears. Stronger, cost-effective and improved functional scores can be obtained by the former. Both early and delayed postoperative rehabilitation programmes have led to comparable outcomes. Guarded results may be anticipated in patients in extremes of age, presence of comorbidities and severe tear patters. Overall, satisfactory results are obtained with timely diagnosis and execution of the appropriate treatment modality.

Subtrochanteric fractures after retrograde femoral nailing. World J Orthop 2015; 6:738-43.

Abstract
Secondary fractures around femoral nails placed for the management of hip fractures are well known. We report, two cases of a fracture of the femur at the interlocking screw site in the subtrochanteric area after retrograde femoral nailing of a femoral shaft fracture. Only a few reports in the existing literature have described these fractures. Two young men after sustaining a fall presented to us with pain, swelling and deformity in the upper thigh region. On enquiring, examining and radiographing them, peri-implant fractures of subtrochanteric nature through the distal interlocking screws were revealed in both patients who also had histories of previous falls for which retrograde intramedullary nailing was performed for their respective femora. Both patients were managed with similar surgical routines including removal of the existing hardware, open reduction and ace cephallomedullary antegrade nailing. The second case did show evidence of delayed healing and was additionally stabilized with cerclage wires. Both patients had uneventful postoperative outcomes and union was evident at the end of 6 mo postoperatively with a good range of motion at the hip and knee. Our report suggests that though seldom reported, peri-implant fractures around the subtrochanteric region can occur and pose a challenge to the treating orthopaedic surgeon. We suggest these be managed, after initial stabilization and resuscitation, by implant removal, open reduction and interlocking intramedullary antegrade nailing. Good results and progression to union can be expected in these patients by adhering to basic principles of osteosynthesis.

Abstract
BACKGROUND Retrograde femoral nailing is a common method to repair femoral shaft fractures in polytrauma patients. Studies have reported varying incidences of complications associated with retrograde femoral nailing such as knee pain, nonunion, and arthrofibrosis. The objective of this retrospective study was to describe healing and complication rates of 31 patients who underwent retrograde femoral nailing at our academic medical center. METHODS Clinical notes and radiographs were reviewed retrospectively. Data points such as demographics, fracture location on femur, time to union after surgery, presence or absence of comminution, associated injuries, and complications were assessed. RESULTS Average time to union was 4.69 months with no statistically significant relationship found between time to union and age, sex, comminution, or location of fracture. Knee pain was present in 23 % of patients, and distal screw removal was necessary in 19.4 % of patients. DISCUSSION Retrograde femoral nailing is an effective method of femoral shaft fracture fixation in polytrauma patients. The healing rate of femoral shaft fractures fixed with a retrograde nail is the same regardless of location of fracture, age, sex, or comminution. Prevention of tip of nail lying into the knee and early physical therapy are important to prevent arthrofibrosis knee.
