Mortality and Revision Surgery Are Increased in Patients With Parkinson's Disease and Fractures of the Femoral Neck

Higher Comorbidities are Correlated With Readmission Following Arthroplasty for Femoral Neck Fracture

Background

A desire to control cost and improve patient outcomes following arthroplasty led to the introduction of the Center for Medicare and Medicaid Service Comprehensive Care for Joint Replacement Program. Hemi and total hip arthroplasty for femoral neck fracture has been shown to have worse outcomes than those for osteoarthritis. However, little has been studied about the effect of comorbidities on costs associated with arthroplasty for femoral neck fracture. This study investigates how the number of comorbidities influence 90-day outcomes and cost following hemi or total hip arthroplasty for displaced femoral neck fracture in patients covered by the Comprehensive Care for Joint Replacement bundle.

Methods

We reviewed all Medicare hip fracture patients undergoing hemi or total hip arthroplasty at our institution between April 2016 and November 2020. Basic demographic and perioperative information was collected. The primary outcome was hospital readmission within 90 days. The data set captured 90-day readmission to any institution, not just within our system. Secondary outcomes included 90-day reoperation and outpatient complications. Multiple logistic regression was used to examine the influence of number of comorbidities on the primary and secondary outcomes while controlling for other variables.

Results

The cohort comprised 378 patients (72% female), mean age 82 (±9) years, mean body mass index 23.4 (±4.7) kg/m2. For every additional comorbidity, the odds of related readmission without reoperation increased by 1.261 (95% confidence interval [1.055-1.507], P = .011). Odds of reoperation and odds of outpatient complication did not show statistical significance with the available numbers.

Conclusions

Increasing preoperative comorbidities results in a higher odd of readmission within 90 days following arthroplasty for femoral neck fracture in this Medicare population.

Risk Factors for 30-Days Mortality After Proximal Femoral Fracture Surgery, a Cohort Study

Purpose

The primary objective of this study was to identify new risk factors and to confirm previously reported risk factors associated with 30-day mortality after hip fracture surgery.

Patients and methods

A prospective hip fracture database was used to obtain data. In total, 3523 patients who underwent hip fracture surgery between 2011 and 2021 were included. Univariable and multivariable logistic regression was used to screen and identify candidate risk factors. Twenty-seven baseline factors and 16 peri-operative factors were included in the univariable analysis and 28 of those factors were included in multivariable analysis.

Results

8.6% of the patients who underwent hip fracture surgery died within 30 days after surgery. Prognostic factors associated with 30-day mortality after hip fracture surgery were as follows: age 90-100 years (OR = 4.7, 95% CI: 1.07-19.98, p = 0.041) and above 100 years (OR = 11.3, 95% CI: 1.28-100.26, p = 0.029), male gender (OR = 2.6, 95% CI: 1.97-3.33, p < 0.001), American Society of Anesthesiologists (ASA) 3 and ASA 4 (OR = 2.1, 95% CI: 1.44-3.14, p < 0.001), medical history of dementia (OR = 1.7, 95% CI: 1.25-2.36, p = 0.001), decreased albumin level (OR = 0.94, 95% CI: 0.92-0.97, p < 0.001), decreased glomerular filtration rate (GFR) (OR = 0.98, 95% CI: 0.98-0.99, p < 0.001), residential status of nursing home (OR = 2.1, 95% CI: 1.44-2.87, p < 0.001), higher Katz Index of Independence in Activities of Daily Living (KATZ-ADL) score (OR = 1.1, 95% CI: 1.01-1.16, p=0.018) and postoperative pneumonia (OR = 2.4, 95% CI: 1.72-3.38, p < 0.001).

Conclusion

A high mortality rate in patients after acute hip fracture surgery is known. Factors that are associated with an increased mortality are age above 90 years, male gender, ASA 3 and ASA 4, medical history of dementia, decreased albumin, decreased GFR, residential status of nursing home, higher KATZ-ADL score and postoperative pneumonia.

Clinical outcomes in patients with neurological disorders following periacetabular tumor removal and endoprosthetic reconstruction of the hemipelvis

Background

Surgical treatment of musculoskeletal tumors in the periacetabular region present extremely difficult due to the complex anatomy and need for reconstruction. Orthopedic surgeons face more difficulties in patients with neurological conditions, which can cause increased muscle tone, an elevated risk of fractures, and compromised bone quality. There is limited evidence regarding endoprosthetic reconstruction for periacetabular tumors in individuals with neurological disorders.

Methods

We conducted a single-center retrospective study to examine the outcomes of patients with preexisting neurological conditions who underwent surgery to remove periacetabular tumors and who underwent endoprosthesis reconstruction. Clinical presentation, detailed neurological conditions, complications, and functional outcomes were studied.

Results

Sixteen out of the 838 patients were identified (1.91%), with a mean follow-up time of 33 months. The primary neurological conditions encompassed Parkinson's disease, Alzheimer's disease, dementia, and cerebral ischemic stroke. Every patient was diagnosed with periacetabular lesions that were either primary or oligometastatic. They underwent tumor resection and subsequently received endoprosthetic reconstruction of the hemipelvis. Three patients developed metastasis lesions later, and two patients experienced tumor recurrence. Five cases experienced hip dislocation-one with periprosthetic fracture and one with surgical site infection. The position of the prosthetic rotating center was not correlated with dislocation. The reoperation rate was 31.25%. The cohort of patients all presented with more extended hospital stays and rehabilitation. In 3 patients, the general functional score was good, while in 6 patients, it was fair; in 7 patients, it was regarded as poor. The average MSTS93 score was 49.71%.

Conclusion

Endoprosthetic reconstruction after periacetabular tumor resection is an effective way to eliminate tumors and salvage limbs. However, this group of patients has an increased likelihood of secondary surgery, complications, extended hospital stay, and no significant improvement in functional outcomes. Despite the diverse nature of the cohort, it is recommended to consider enhanced soft tissue reconstruction, supervised functional recovery and rehabilitation training.

Cold Welding of the Synthes Femoral Neck System Encountered at Conversion to Arthroplasty: A Case Report

CASE

The Synthes Femoral Neck System (FNS) is a relatively new device available to the market in 2019 designed to reduce complication and revision rates after femoral neck fracture stabilization. We present a 77-year-old man with Parkinson disease and avascular necrosis after femoral neck fracture initially managed with the FNS. Subsequent challenges in device removal occurred because of its propensity for bony integration, plate and locking screw welding, and screw head recess destruction.

CONCLUSION

Surgeons must recognize the need for additional available equipment (e.g., burr or broken screw removal set) for successful extraction when FNS removal is required.

Periprosthetic Tibial Plateau Fractures After Unicompartmental Knee Arthroplasty Are Successfully Treated With Open Reduction and Internal Fixation

Periprosthetic tibial fractures after unicompartmental knee arthroplasty (UKA) are rare but devastating events. Given the relative infrequency of these injuries, treatment strategies are not well defined. The goal of this retrospective case series is to report the findings for a series of patients who underwent open reduction and internal fixation (ORIF) of periprosthetic fracture after UKA, including radiographic alignment, Knee Society Score (KSS), and failure rate. Patients were identified by the International Classification of Diseases code for periprosthetic tibial plateau fractures. Electronic medical records and radiographs were retrospectively reviewed. Fracture patterns and coronal and sagittal alignment of UKA components were measured on radiographs. Clinical outcomes, including range of motion assessment, visual analog scale pain score, and KSS, were collected at final follow-up. Eight patients satisfied the inclusion criteria for this study. Fractures occurred at a median of 14 days (range, 5-52 days) after UKA, and all showed a vertical shear pattern that exited at the meta-diaphyseal junction. Of the 8 fractures, 7 (87.5%) healed to radiographic and clinical union after the initial ORIF. One patient required reoperation for hardware failure. Mean visual analog scale pain score and KSS at final follow-up were 3 and 85±14, respectively. Periprosthetic tibial plateau fractures after UKA commonly occur as a vertical shear fracture exiting at the metadiaphyseal junction. The use of ORIF with a 3.5-mm plate in buttress mode is a reliable method for treatment of these fractures. Restoration of alignment and motion is achievable, but residual pain may affect patient-reported outcome scores. [Orthopedics. 2022;45(5):287-292.].

Postoperative complications, mortality, and quality of in-hospital care among hip fracture patients with Parkinson's disease

AIM

The aim of this study was to investigate the association between Parkinson's disease (PD) and postoperative complications, mortality, and quality of in-hospital care in patients with hip fracture.

METHODS

We included patients aged 65+ years with an incident hip fracture from 2004-2017, registered in the Danish Multidisciplinary Hip Fracture Registry. Patients with PD were identified using diagnosis codes prior to hip fracture. Using log-binomial regression, we calculated both 30-day crude and adjusted risk ratios (aRR) with 95% confidence intervals (CIs) for the following outcomes: any hospital-treated infections, pneumonia, urinary tract infection, sepsis, community-treated infections, cardiovascular events, mortality, and fulfilment of quality indicators of in-hospital care. Analyses were adjusted for age, sex and Charlson comorbidity index score.

RESULTS

We identified 77,550 hip fracture patients of which 1,915 had PD. Compared to non-PD, patients with PD had higher risk of any hospital-treated - (aRR = 1.27 (CI: 1.10-1.45) and community-treated infection (aRR = 1.22 (CI: 1.13-1.32)), pneumonia (aRR = 1.38 (1.11-1.69)), urinary tract infection (aRR of 1.58 (CI: 1.28-1.92)) and sepsis (aRR = 1.18 (CI: 0.67-1.89)), but a reduced risk of cardiovascular events (aRR = 0.59 (CI: 0.41-0.82)). The aRR for 30-day mortality was 1.11 (CI: 0.97-1.27) for PD vs non-PD patients, and the aHR for 1-year mortality was 1.19 (CI: 1.09-1.30). The aRRs for fulfillment of all relevant quality indicators was about 1 for PD vs non-PD patients.

CONCLUSION

Hip fracture patients with PD have a higher risk of infections and mortality within 30 days after surgery after adjustment for sex, age, and comorbidity. They do, however, receive comparable quality of in-hospital care after hip fracture compared to non-PD patients.

Risk Factors for Aseptic Revision of Operatively Treated Ankle Fractures

BACKGROUND

Early revision rates within 12 months after ankle fracture open reduction internal fixation (AF-ORIF) are fairly low; however, they remain relevant given the volume of ankle fractures occurring annually. Understanding these rates is complex because reoperation due to technical or mechanical complications is typically reported alongside soft tissue-related problems such as symptomatic hardware, wound dehiscence, or infection. There are limited data identifying risk factors specifically for revision of ankle fracture fixation in the absence of soft tissue complications. Understanding variables that predispose to aseptic technical and mechanical failure without this confounder may provide insight and improve patient care.

METHODS

A retrospective cohort study was performed at 2 large academic medical centers. Research Patient Data Registry (RPDR) data available from 2002 to 2019 were used to identify patients who underwent aseptic revision of AF-ORIF within 12 months (n = 33). A control group (n = 100) was selected by identifying sequential patients who underwent AF-ORIF not requiring revision within 12 months. Multiple factors were recorded for all patients in both cohorts. Each fracture was also evaluated according to the Ankle Reduction Classification System (ARCS) of Chien et al,⁸ which categorizes biplanar talar displacement in relation to a central tibial plumb line into 1 of 3 grades: A (0-2 mm), B (3-10 mm), and C (>10 mm). Adapted from its original purpose of grading reduction quality, we applied ARCS to pre-reduction radiographs to assess initial fracture displacement. All variables collected were compared in univariate analysis. Variables that achieved significance in univariate comparisons were included as candidates for multivariable analysis.

RESULTS

Final multivariable logistic regression modeling demonstrated the following factors to independently predict the need for aseptic revision surgery: documented falls in the early postoperative period (aOR, 298; 95% CI, 15.4, 5759; P < .001), movement-altering disorders (aOR, 81.7; 95% CI, 4.12, 1620; P = .004), a nonanatomic mortise (medial clear space [MCS] > superior clear space [SCS]) on immediate postoperative imaging (aOR, 38.4; 95% CI, 5.53, 267; P < .001), initial coronal plane tibiotalar displacement >10 mm and sagittal plane tibiotalar dislocation (ARCS-C) (aOR vs ARCS-A, 25.8; 95% CI, 2.81, 237; P = .004), substance abuse (aOR, 15.7; 95% CI, 2.66, 92.8; P = .002), and polytrauma (aOR, 12.3; 95% CI, 2.02, 74.8; P = .006).

CONCLUSION

In this investigation we found a notable increase in risk for revision surgery after AF-ORIF for patients who had one of the following: (1) falls in the early postoperative period, (2) movement-altering disorders, (3) a nonanatomic mortise (MCS > SCS) on immediate postoperative imaging, (4) more severe initial fracture displacement, (5) substance abuse, or (6) polytrauma. Identifying these factors may allow surgeons to better understand risk and counsel patients, and may serve as future targets for intervention aimed at improving patient safety and outcomes after ankle fracture ORIF.

Understanding the influence of pain and fatigue on physical performance, fear of falling and falls in people with Parkinson's disease: a pilot study

Objective: Pain and fatigue are highly prevalent debilitating symptoms in Parkinson's disease (PD), however, their relationship with physical performance, fear of falling (FOF) and falls is not clear. We aim in this pilot study to investigate the relationship of pain and fatigue with physical performance, FOF and falls in people with Parkinson's disease (PwPD). Materials & methods: 53 PD patients were assessed for fall history, physical performance, FOF, pain and fatigue. Results: Pain and fatigue are significantly associated with physical performance and FOF (p ≤ 0.002). Pain and fatigue were different between fallers and non-fallers (p < 0.5), but only fatigue could distinguish fallers from non-fallers (area under the receiver operating characteristics curve = 0.81; p < 0.0001). Conclusion: This pilot study indicated that FOF in PwPD is significantly associated with pain and fatigue. Furthermore, fatigue level is related to fall history. By addressing pain and fatigue, we may ameliorate the deterioration of FOF and falls in PwPD.

A clinical nomogram predicting unplanned intensive care unit admission after hip fracture surgery

BACKGROUND

Despite the improvement of surgical procedures and perioperative management, a portion of patients were still at high risk for intensive care unit admission owing to severe morbidity after hip fracture surgeries. The purpose of this study was to analyze influencing factors and to construct a clinical nomogram to predict unscheduled intensive care unit admission among inpatients after hip fracture surgeries.

METHODS

We enrolled a total of 1,234 hip fracture patients, with 40 unplanned intensive care unit admissions, from January 2011 to December 2018. Demographics, chronic coexisting conditions at admission, laboratory tests, and surgical variables were collected and compared between intensive care unit admission and nonadmission groups using univariate analysis. The optimal lasso model was refined to the whole data set, and multivariate logistic regression was used to assign relative weights. A nomogram incorporating these predictors was constructed to visualize these predictors and their corresponding points of the risk for unplanned intensive care unit admission. The model was validated temporally using an independent data set from January 2019 to December 2019 by receiver operating characteristic area under the curve analysis.

RESULTS

In the development group, we identified age, chronic heart failure, coronary heart disease, chronic obstructive pulmonary disease, Parkinson disease, and serum albumin and creatinine concentration were associated with unscheduled intensive care unit admission using multivariate analysis. The final model had an area under the curve of 0.854 (95% confidence interval, 0.742-0.966). The median calculated odds ratio of intensive care unit admission based on the nomogram was significantly higher for patients in the intensive care unit admission group than in the non-intensive care unit admission group (65.93% vs 0.02%, P < .01). The validation group proved its high predictive power with an area under the curve of 0.96 (95% confidence interval, 0.91-0.99).

CONCLUSION

In this study, we identified several independent factors that may increase the risk for unexpected intensive care unit admission after hip fracture surgery and developed a clinical nomogram based on these variables. Preoperative evaluation using this nomogram might facilitate advanced intensive care unit resource management for high-risk patients whose conditions might easily deteriorate if not closely monitored in general wards after surgeries.

Clinical outcomes in elective total hip arthroplasty in Parkinson's disease: a systematic review of the literature

Parkinson’s disease (PD) poses a significant challenge for the arthroplasty surgeon, owing to excessive muscle tone, higher fracture risk and poor bone quality. Several studies have reported high mortality, early failure and perioperative complications associated with hip fracture surgery in PD; however, no higher-level evidence exists regarding elective hip arthroplasty.

The aim of our study was to perform a systematic review to evaluate the evidence basis and clinical outcomes pertaining to patients with underlying Parkinson’s disease undergoing elective total hip arthroplasty (THA).

We searched MEDLINE, EMBASE and The Cochrane Central Register of Controlled Trials to identify studies evaluating the safety and clinical outcomes of THA in patients suffering from Parkinson’s. Our review conforms to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.

Ten studies encompassing 49,730 patients were included in our systematic review. Qualitative synthesis demonstrated comparable results between PD patients and controls with respect to one-year mortality and surgical site infections. PD patients experienced more medical complications, had a longer hospital stay and worse long-term implant survival. Some studies also reported a higher rate of dislocation, periprosthetic fractures and aseptic loosening.

Decisions about the optimal articulation, the utilization of cemented components, dual-mobility cups or constrained liners were not uniform among included studies.

THA in patients with Parkinson’s disease can offer significant functional gains and pain relief. Surgical considerations pertain to the approach and ways to address instability, whereas emphasis should be placed on appropriate counselling and exploring whether potential improvement of life quality outweighs the risks.

Surgical outcome of upper extremity fractures in patients with Parkinson's disease

Patients with Idiopathic Parkinson’s Disease (PD) have an increased risk for fractures. Currently, many studies have reported inferior outcomes in PD patients after orthopedic procedures. However, there are very few studies assessing the outcome of upper extremity fractures (UEF) in PD patients. In this study, we reviewed 40 patients with PD that received surgical intervention for an UEF. We retrospectively reviewed patients with PD that received surgical fixation for an UEF at a tertiary trauma center. The primary objective was to determine the treatment failure rate after surgical fixation. The secondary outcomes include mode of failure, time to treatment failure, length of hospital stay, readmission rate, reoperation rate, and postoperative complications. A total of 40 patients with PD (42 fractures) underwent surgery. The most common fracture type was radius fracture (n = 19), followed by humerus fracture (n = 15), metacarpal/phalangeal fracture (n = 5), clavicle fracture (n = 2) and olecranon fracture (n = 1). The overall treatment failure rate was 40.5% (n = 17). The time to treatment failure was 1.24 ± 3.1 months and length of hospital stay was 6 ± 3.9 days, the readmission rate within 30 days was 14% (n = 6), and reoperation rate was 14% (n = 6). The complication rate was 16.6% (n = 7) and patients with humeral fractures appeared to have the longest hospital stays (6.6 days) and increased complication rates (13%, n = 2). Patients with PD have high treatment failure rates despite surgical fixation of an UEF. These patients often have a frail status with multiple comorbidities which may complicate their postoperative course.

Factors Associated With Mortality After Surgical Management of Femoral Neck Fractures

BACKGROUND

Hip fractures are recognized as one of the most devastating injuries impacting older adults because of the complications that follow. Mortality rates postsurgery can range from 14% to 58% within one year of fracture. We aimed to identify factors associated with increased risk of mortality within 24 months of a femoral neck fracture in patients aged ≥50 years enrolled in the FAITH and HEALTH trials.

METHODS

Two multivariable Cox proportional hazards regressions were used to investigate potential prognostic factors that may be associated with mortality within 90 days and 24 months of hip fracture.

RESULTS

Ninety-one (4.1%) and 304 (13.5%) of 2247 participants died within 90 days and 24 months of suffering a femoral neck fracture, respectively. Older age (P < 0.001), lower body mass index (P = 0.002), American Society of Anesthesiologists (ASA) class III/IV/V (P = 0.004), use of an ambulatory aid before femoral neck fracture (P < 0.001), and kidney disease (P < 0.001) were associated with a higher risk of mortality within 24 months of femoral neck fracture. Older age (P = 0.03), lower body mass index (P = 0.02), use of an ambulatory aid before femoral neck fracture (P < 0.001), and having a comorbidity (P = 0.04) were associated with a higher risk of mortality within 90 days of femoral neck fracture.

CONCLUSIONS

Our analysis found that factors that are indicative of a poorer health status were associated with a higher risk of mortality within 24 months of femoral neck fracture. We did not find a difference in treatment methods (internal fixation vs. joint arthroplasty) on the risk of mortality.

Parkinson's disease and hip fractures: Are complications and mortality rates increased?

PURPOSE

The aim of this study was to assess patients with Parkinson's disease (PD) in comparison with patients without PD for the treatment of hip fractures. Therefore, we performed a mono-centre study including 145 patients with PD and 2135 consecutive patients without PD as a concurrent group (C).

METHODS

For analysis, we used our database, in which any type of hip fracture was enrolled. The study period ranged from 2007 to 2017, and the patient age was ≥ 60 years. Overall, 10 variables were included. The primary measures were operations for any reason, infection, dislocation, failure, and mortality. The secondary outcome was any de novo fracture based on a new fall. The follow-up period for every living patient was 2 years after the operation. Any missing data were retrospectively evaluated via telephone. The hypothesis was no effect between the two groups.

RESULTS

No significant differences were observed regarding revision (p = 0.348), infection (p = 0.207), dislocation (p = 0.785), failure of internal fixation (p = 0.368), failure of replacement (p = 0.174), and de novo fractures (p = 0.287). However, patients with PD sustained a contralateral hip fracture significantly more often (p < 0.001). Kaplan-Meier survival analysis demonstrated no effects up to 2 years after the operation (log rank 0.259).

CONCLUSION

Compared to a concurrent group, patients with PD demonstrated no more complications and similar mortality rates within 2 years after surgery. The rate of dislocation after hip replacement was also not increased. A contralateral hip fracture was the most common de novo fracture in PD. Further studies should investigate measures reducing the risk for any new falls in PD.

The outcome for surgical fixation of distal radial fractures in patients with idiopathic Parkinson's disease: a cohort study

Introduction

Idiopathic Parkinson’s disease (PD) is a progressive neurologic disorder causing postural instability and unsteady gait. These patients are at increased risk for fractures and have inferior outcomes after treatment. Several studies have evaluated the incidence and outcome of PD patients after hip fractures. However, there are limited studies assessing the outcome of upper extremity fractures in these patients. In this study, we evaluated the outcome of PD patients that received surgical intervention for distal radial fractures (DRF). We hypothesize that these patients have an inferior outcome after surgery in comparison with non-PD patients.

Methods

Between May 2005 and May 2017, we retrospectively reviewed all of the patients with DRF and subsequently underwent open reduction and internal fixation (ORIF) at a level 1 trauma center. All of the surgeries were performed by fellowship-trained orthopedic surgeons. The inclusion criteria include patients with a definitive diagnosis of PD, non-pathological DRF, and a minimum follow-up of 1 year or up until the time of treatment failure was noted. Each PD patient was matched for age and gender to 3 non-PD patients. The primary objective was to determine the failure rate after surgical fixation for DRF. The secondary outcomes include time to treatment failure, reoperation rate, readmission rate, length of hospital stay, and postoperative complications.

Results

A total of 88 patients were included in this study (23 PD, 65 non-PD patients). All underwent ORIF and received standard postoperative follow-ups. The overall treatment failure rate in PD was 39.1% vs. 4.6% in the non-PD group (p < 0.05). The time to treatment failure were 9.11 ± 3.86 weeks and 14.67 ± 5.8 weeks for PD and non-PD, respectively (p < 0.05). PD patients had a significantly higher rate of failure when k-wires and ESF were used (p < 0.05%), while loss of reduction was the most common mode of failure in PD (44.4%). The length of hospital stay for PD was 5.3 ± 4.69 days compared with 3.78 ± 0.96 days for non-PD (p = 0.01). There were 3 PD patients readmitted within 30 days after surgery, and 1 patient had pneumonia after the surgery.

Conclusion

This study revealed that patients with PD have a high treatment failure rate despite surgical intervention for DRF. PD patients had a longer hospital stay and had a shorter time to treatment failure. In treating PD patients complicated with DRF, the surgeon must take into consideration the complex disease course of PD and the associated comorbidities such as osteoporosis, frail status, and frequent falls. Rehabilitation and disposition plans should be discussed in advance and longer hospital stays should be expected.

Effect of Parkinson's Disease on Hemiarthroplasty Outcomes After Femoral Neck Fractures

BACKGROUND

The purpose of this study was to evaluate the outcomes following hemiarthroplasty (HA) for femoral neck fractures (FNFs) in patients with Parkinson's disease (PD) compared with patients without PD.

METHODS

This was a retrospective review utilizing the Nationwide Readmissions Database, a national database incorporating inpatient hospitalization information. Using the Nationwide Readmissions Database, patients who underwent HA for FNF between 2010-2014 were identified. International Classification of Diseases, 9th Revision, codes were used to find a subset of patients with PD. Primary outcomes of interest included death, hospital readmission, periprosthetic fracture, postoperative dislocation, any revision surgery, and revision surgery for instability, fracture, or infection.

RESULTS

There were a total of 7721 (4%) patients with PD. There was no difference in the risk of death or any postoperative complications during index hospitalization for these patients. However, PD patients had an increased risk of hospital readmission (odds ratio [OR] = 1.13, 95% confidence interval [CI]: 1.02-1.26) and postoperative dislocation (OR = 2.10, 95% CI: 1.58-2.80) within 90 days of surgery. PD patients also had an increased risk of revision surgery for instability (OR = 2.20, 95% CI: 1.48-3.28), despite no difference in the risk of any revision surgery, revision surgery for fracture, or revision surgery for infection.

CONCLUSION

In this retrospective cohort study, PD patients who underwent a HA for FNF had a greater risk of postoperative dislocation and revision surgery for instability within 90 days. These findings are not only important to consider when managing these at-risk patients but also stress the need to allocate operative and postoperative resources to prevent and treat instability.

[Perioperative treatment progress of Parkinson's disease with hip fracture]

Objective

To review the progress of perioperative treatments for patients of Parkinson's disease and hip fractures.

Methods

The related literature of treatments for patients of Parkinson's disease and hip fractures were reviewed and analyzed from the aspects such as the perioperative management, selection of operation ways, and prognosis.

Results

The patients of Parkinson's disease are more likely to sustain hip fractures because of postural instability and osteoporosis. The perioperative treatments for patients of Parkinson's disease and hip fractures should be determined by orthopedists, neurologist, anesthesiologist, and physical therapist. There is still controversy about the selection of operation and surgical approach. And the prognosis of patients of Parkinson's disease and hip fractures are associated with the severity of Parkinson's disease.

Conclusion

There are few clinical studies about the patients of Parkinson's disease and hip fractures. The mid-term and long-term functional outcomes of patients of Parkinson's disease and hip fractures are unsufficient. And the best treatments of patients of Parkinson's disease and hip fractures need to be further explored.

Hip fractures and Parkinson's disease: A case series

There are no specific guidelines for treating Parkinson's disease patients who present with a hip fracture. Here we present a large cohort of patients with Parkinson's disease who suffered hip fractures. Our aim was to assess for differences between a Parkinson's disease population and a non-Parkinson's disease population with hip fractures and make recommendations on management guidelines. We performed a comprehensive analysis of prospectively collected data on all patients with hip fracture who were admitted into our department over a period of 29 years. In total 9225 patients with hip fractures were included in this study, 452 (4.9%) patients had Parkinson's disease. The mobility scores were worse pre- and post-operatively in the Parkinson's group as were mini-mental scores and ASA grade. Post-operative complications were similar between the two groups, with no difference in dislocation rate or wound complications. However, other outcomes including mobility and mortality rate at 1year were worse in the Parkinson's group. These patients also had a longer hospital stay and were more likely to be immobile and discharged to an institution. We recommend that Parkinson's disease patients should be assessed more thoroughly in the peri-operative period and arrangement for rehab and discharge planning should commence as soon as possible following admission. The consent process should reflect longer hospital stays, worse mobility, higher mortality and increased likelihood of discharge to institution but concern over increased complications, specifically dislocation was not evident in our data.

Outcomes After Non-neurological Surgery in Patients With Parkinson's Disease: A Nationwide Matched Cohort Study

Patients with Parkinson disease (PD) were known to have increased risk of complications during hospitalization. The purpose of this study is to validate the global features of postoperative adverse outcomes for patients with PD.Using reimbursement claims from Taiwan's National Health Insurance Research Database, we conducted a nationwide retrospective cohort study of 6455 patients with preoperative PD receiving major surgery during 2008 to 2012. With a propensity score matching procedure, 12,910 surgical patients without PD were selected for comparison. The adjusted odds ratios (ORs) and 95% confidence intervals (CIs) for 9 major postoperative complications and 30-day postoperative mortality associated with preoperative PD were calculated in the multivariate logistic regressions.Patients with PD had increased risk of postoperative pulmonary embolism (OR 2.72, 95% CI 1.45-5.10), stroke (OR 1.77, 95% CI 1.53-2.05), pneumonia (OR 1.98, 95% CI 1.70-2.31), urinary tract infection (OR 1.52, 95% CI 1.35-1.70), septicemia (OR 1.54, 95% CI 1.37-1.73), acute renal failure (OR 1.36, 95% CI 1.07-1.73), and mortality (OR 1.45, 95% CI 1.06-1.98). The association between preoperative PD and postoperative adverse events was significant in both sexes and every age group. Low income, ≥65 years of age, surgery not in medical center, highest quartile of PD medication users, and more medical conditions worsen the risk of postoperative adverse events in patients with PD.This study showed increased postoperative complications and mortality in patients with PD. Our findings suggest that revision of postoperative care protocols for this population is urgently needed.
