Abstract
Background Managing intertrochanteric fractures presents challenges for orthopedic surgeons, not only in fixing the fracture but also in preventing and managing associated complications, especially in the vulnerable geriatric population. Cephalomedullary nails are commonly used for surgical fixation due to their favorable functional profile, which preserves the hip's abductor lever arm and proximal femur anatomy. However, there's a lack of data comparing two major options: proximal femoral nail (PFN) and proximal femoral nail anti-rotation (PFNA). This study aimed to compare the radiological fracture reduction and fixation as well as functional outcomes of these two implants in treating intertrochanteric fractures. Methods The study, spanning 24 months, involved a prospective comparative design. Participants included patients diagnosed with intertrochanteric femur fractures classified as AO Type 31 A1, AO Type 31 A2, and AO Type 31 A3. Fifty patients were evenly distributed into PFN and PFNA groups. Preoperatively, clinical and radiological assessments were conducted, along with serum vitamin D level measurements. Surgeries, performed under anesthesia with image intensifier guidance, followed defined reduction and implant insertion protocols for each group. Postoperatively, evaluations were conducted up to six months, examining parameters such as tip-apex distance (TAD), Cleveland index, and modified Harris hip score, while documenting intraoperative duration and blood loss. Data analysis utilized the statistical software Statistical Package for Social Sciences (SPSS), version 22.0 (IBM Corp., Armonk, NY), employing descriptive statistics, chi-square tests, independent t-tests, and paired t-tests, with significance set at p < 0.05. Results In our study, 50 patients were enrolled, with equal gender distribution (64.0% male, 36.0% female, p=1.000). The mean ages in the PFN and PFNA groups were 66.2 ± 9.8 years and 66.4 ± 11.3 years, respectively (p=0.936). All fractures united by six months, with no implant-related complications reported. PFNA showed significantly lower blood loss and shorter surgery durations (p<0.001). TAD and neck shaft angle were similar between groups (p=0.826, p=0.555). Cleveland index placement and modified Harris hip score improvement were comparable (p=0.836, p<0.001). Predominant vitamin D deficiency was observed in both groups. Conclusion PFNA offers measurable intraoperative benefits over conventional PFN in terms of operative time, blood loss, and need for fluoroscopic imaging. However, no statistically observable benefits were noted in postoperative functional outcomes or complications between the two implants.

Abstract
BACKGROUND AND PURPOSE To date, the mid- and long-term outcomes of the Collum Femoris Preserving (CFP) stem compared with conventional straight stems are unknown. We aimed to compare physical function at a 5-year follow-up and implant survival at an average of 10-year follow-up in an randomized controlled trial (RCT). METHODS This is a secondary report of a double-blinded RCT in 2 hospitals. Patients aged 18-70 years with hip osteoarthritis undergoing an uncemented primary THA were randomized to a CFP or a Zweymüller stem. Patient-reported outcomes, clinical tests, and radiographs were collected at baseline, 2, 3, 4, and 5 years postoperatively. Primary outcome was the Hip disability and Osteoarthritis Outcome Score (HOOS) function in activities of daily living (ADL) subscale. Secondary outcomes were other patient-reported outcomes, clinical tests, adverse events, and implant survival. Kaplan-Meier and competing risk survival analyses were performed with data from the Dutch Arthroplasty Registry. RESULTS We included 150 patients. Mean difference between groups on the HOOS ADL subscale at 5 years was -0.07 (95% confidence interval -5.1 to 4.9). Overall survival was 92% for the CFP and 96% for the Zweymüller stem. No significant difference was found. CONCLUSION No significant differences were found in physical function at 5-year and implant survival at 10-year follow-up between the CFP and Zweymüller stems. When taking cup revisions into account, the CFP group showed clinically inferior survival.

Abstract
Background The purposes of this study were to determine the accuracy of our cup positioning method and to evaluate the dislocation rate after total hip arthroplasty (THA). Methods After positioning the patient in the lateral decubitus position on the operation table, an anteroposterior view of the hip was taken. The pelvic pitch was measured on the X-ray. A positive pitch was defined as the caudal rotation of the upper hemipelvis. Our target abduction of the cup was 43°. We used the cup holder to guesstimate the cup abduction. In a preliminary study, we found that the weight of the cup holder increased the pelvic pitch by 5°. Thus, the target abduction of the cup holder was calculated by a formula: 43° - pelvic pitch - 5°. During the cup insertion, the cup holder was anteverted to the calculated target according to the concept of combined anteversion. We evaluated 478 THAs (429 patients), which were done with the use of the method. Results The mean cup abduction was 43.9° (range, 32.0°-53.0°) and the mean error of cup abduction was 2.4° (standard deviation [SD], 2.0°; range, 0.0°-11.0°). The mean cup anteversion was 28.5° (range, 10.0°-42.0°) and the mean error of cup anteversion was 6.7° (SD, 5.2°; range, 0.0°-27.6°). Of all, 82.4% of the cups (394 / 478) were within the safe zone: 30°-50° abduction and 10°-35° anteversion. During 2- to 5-year follow-up, no hip dislocated. Conclusions Our adjusting method according to the pelvic pitch can be a reliable option for optimizing the cup abduction in THA.

Level of Disability after Total Hip Replacement in Patients with Some COMT Gene Polymorphism. J Clin Med 2023; 12:7652. [PMID: 38137720 PMCID: PMC10743937 DOI: 10.3390/jcm12247652] [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: 10/31/2023] [Revised: 12/05/2023] [Accepted: 12/11/2023] [Indexed: 12/24/2023] Open
Abstract
BACKGROUND The COMT gene encodes the enzyme catechol-O-methyltransferase, which is a key modulator of dopaminergic and adrenergic neurotransmission. Hip osteoarthritis is accompanied by reduced mobility and some level of disability. In our study, we analyzed the association between some COMT gene polymorphisms and reduced mobility in patients after total hip replacement (THR). METHODS The operative procedures were performed on 195 patients with symptomatic and radiologically advanced hip osteoarthritis. In the postoperative follow-up, we assessed hip function with the Harris Hip Score (HHS) and the degree of disability with the Oswestry Disability Index (ODI). These procedures were repeated three times at defined intervals (one week, six weeks, and six months) after the total hip replacement. Genomic DNA was extracted from peripheral blood. SNPs in the COMT genes rs4680:A>G, rs6269:A>G, rs4633:C>T, and rs4818:C>G were genotyped. RESULTS Our findings suggest an association between COMT gene variability and the level of disability measured by the Oswestry Disability Index (ODI) in patients after total hip replacement (THR). CONCLUSIONS A higher number of COMT G alleles (rs4818) is an independent factor in a significant reduction in disability degree at both one week and six months after total hip replacement (THR), regardless of age or gender.

Abstract
BACKGROUND Intertrochanteric fractures are a global health concern, especially in aging populations like the Republic of Korea. Surgical treatments like intramedullary nailing are preferred for their benefit. Various hip nails are used worldwide, each with unique features and challenges. This study aims to compare the GS hip nail with the Affixus hip fracture nail for the treatment of intertrochanteric fractures. MATERIAL AND METHODS This retrospective study, conducted at a single center, included 179 patients who underwent intramedullary nailing for intertrochanteric fractures using the GS hip nail or the Affixus hip fracture nail. Excluding specific cases, 43 patients in the GS group and 46 in the Affixus group met the minimum 6-month follow-up criteria. RESULT The GS group exhibited a significantly shorter mean operation time (43.26 min) compared to the Affixus group (51.11 min). Radiographically, both groups showed no significant differences in their reduction quality, tip, and apex distance (TAD), or Cleveland index in the immediate postoperative window. However, the GS group achieved a greater valgus reduction based on the contralateral femoral neck shaft angle (NSA). At 6 months post-operation, there were no significant differences in TAD or advancement and sliding distances. Complication rates were similar between the two groups, with no implant breakages. Clinical outcomes, as measured via mHHS and EQ-5D-5L, showed no significant differences. Despite a slightly higher implant cost, the GS group had a lower total hospital cost than the Affixus group, but this was not statistically significant. CONCLUSIONS This study highlights the efficiency of the GS hip nail in reducing the operation time compared to the Affixus hip fracture nail with comparable radiologic and clinical outcomes. Further research with long-term follow-up and larger patient studies are needed to fully assess its effectiveness in improving patient outcomes in hip fracture treatment.

Abstract
Total hip arthroplasty (THA) is a successful orthopaedic surgical procedure, and its longevity depends on bearing components and implant fixation. Optimizing polyethylene and ceramics has led to improved wear parameters and contributed to improved long-term outcomes. The present systematic review investigated whether time span from implantation, patient characteristics and performance status exert an influence on liner wear and head migration in THA. This study was conducted in conformity to the 2020 PRISMA guidelines. All the clinical investigations which reported quantitative data on the amount of liner wear and head migration in THA were considered. Only studies which reported quantitative data at least on one of the following patient characteristics were suitable: mean age, mean BMI (kg/m2), sex, side, time span between the index THA and the last follow-up (months) were eligible. A multiple linear model regression analysis was employed to verify the association between patient characteristics and the amount of liner wear and/or head migration. The Pearson Product-Moment Correlation Coefficient was used to assess the association between variables. Data from 12,629 patients were considered. The mean length of the follow-up was 90.5 ± 50.9 months. The mean age of patients at surgery was 58.4 ± 9.4 years, and the mean BMI was 27.2 ± 2.5 kg/m2. 57% (7199 of 12,629 patients) were women, and in 44% (5557 of 12,629 patients) THAs were performed on the left. The mean pre-operative Harris hip score was 46.5 ± 6.0 points. There was evidence of a moderate positive association between the amount of liner wear and the time elapsed between the index surgery to the follow-up (P = 0.02). There was evidence of a moderate positive association between the amount of head migration and the time elapsed between the index surgery to the follow-up (P = 0.01). No further statistically significant association was found. The time elapsed between the index surgery to the follow-up was the most important factor which influence the head migration and liner wear in THA. Patients' characteristics and preoperative physical activity did not influence the amount of head migration and liner wear.

Abstract
BACKGROUND Total hip arthroplasty (THA) decreases pain and improves function in patients with osteoarthritis. In some cases, both hips have been operated simultaneously. Our aim was to report patients' pain and physical function after one- and five-years post-operatively among patients who underwent unilateral THA and those who underwent bilateral THA at the same time in one orthopaedic hospital in Finland. METHODS The study group consisted of 488 patients retrospectively selected patients from a single centre; 421 of them underwent unilateral THA and 67 underwent simultaneous bilateral THA. The patients had two clinical examinations one and five years postoperatively. Systematic data about pain and physical function were collected using the scaled Orton Hip Score (sOHS). Register data on revisions and mortality events were from the Finnish Institute of Health and Welfare. RESULTS At the one-year follow-up, total sOHS was improved remarkably from the preoperative situation, both in the unilateral THA (age and gender adjusted mean improvement 42 points (95% CI: 40 to 44, p < 0.001) and in the bilateral THA groups (age and gender adjusted mean improvement 45 [95% CI: 41 to 49], p < 0.001), with no group differences after five-years of operation (age and gender adjusted p = 0.19). Total sOHS was statistically higher in the bilateral THA compared to the unilateral THA after one year (98 vs. 95, p < 0.001) and five years (97 vs. 95, p = 0.003) of operation. CONCLUSIONS Patients in unilateral THA and bilateral THA groups had increased their physical function, and pain had decreased after one-year follow-up of the primary THA operation, and condition remained after five years of operation. At follow-ups, patients who underwent bilateral THA had slightly better physical function compared to patients who underwent unilateral THA at follow-up; however, this difference had no clinical relevance.

Abstract
Aims This study reports mid-term outcomes after periacetabular osteotomy (PAO) exclusively in a borderline hip dysplasia (BHD) population to provide a contrast to published outcomes for arthroscopic surgery of the hip in BHD. Methods We identified 42 hips in 40 patients treated between January 2009 and January 2016 with BHD defined as a lateral centre-edge angle (LCEA) of ≥ 18° but < 25°. A minimum five-year follow-up was available. Patient-reported outcomes (PROMs) including Tegner score, subjective hip value (SHV), modified Harris Hip Score (mHHS), and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) were assessed. The following morphological parameters were evaluated: LCEA, acetabular index (AI), α angle, Tönnis staging, acetabular retroversion, femoral version, femoroepiphyseal acetabular roof index (FEAR), iliocapsularis to rectus femoris ratio (IC/RF), and labral and ligamentum teres (LT) pathology. Results The mean follow-up was 96 months (67 to 139). The SHV, mHHS, WOMAC, and Tegner scores significantly improved (p < 0.001) at last follow-up. According to SHV and mHHS, there were three hips (7%) with poor results (SHV < 70), three (7%) with a fair score (70 to 79), eight (19%) with good results (80 to 89), and 28 (67%) who scored excellent (> 90) at the last follow-up. There were 11 subsequent operations: nine implant removals due to local irritation, one resection of postoperative heterotopic ossification, and one hip arthroscopy for intra-articular adhesions. No hips were converted to total hip arthroplasty at last follow-up. The presence of preoperative labral lesions or LT lesions did not influence any PROMs at last follow-up. From the three hips that had poor PROMs, two have developed severe osteoarthritis (> Tönnis II), presumably due to surgical overcorrection (postoperative AI < -10°). Conclusion PAO is reliable in treating BHD with favourable mid-term outcomes. Concomitant LT and labral lesions did not negatively influence outcomes in our cohort. Technical accuracy with avoidance of overcorrection is essential in achieving successful outcomes.

[PMID: 37215279 PMCID: PMC10195983 DOI: 10.1016/j.jcot.2023.102163] [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: 03/04/2023] [Accepted: 04/27/2023] [Indexed: 05/24/2023] Open
Abstract
Background: the primary purpose of this study was to assess the ambulatory capacity 12 months after surgery in patients that underwent bipolar hemiarthroplasty (BH) due to unstable intertrochanteric fractures (UITF). Secondly, to identify which preoperative variables influenced these modifications. Methods We retrospectively analyzed a consecutive series of patients older than 80 years with UITF treated with BH between 2010 and 2019. Ambulatory capacity was assessed before surgery, at 3 and 12 months postoperatively, using Koval's classification and the modified Harris Hip Score (mHHS). The registered variables were: gender, age, osteoporosis, Charlson comorbidity index (CCI), ASA classification, body mass index (BMI), and dementia. The identification of variables that impaired postoperative functionality was performed by uni- and multivariate analysis. Results 158 patients were included with a median age of 87 (range 80-102) years and a follow-up of 29.2 (range 12-56) months. The 1-year overall ambulatory capacity impairment was 28.5% and significantly affected pre-fracture community walkers (p = 0.001). A CCI >4 (OR 2.72; p = 0.044), dementia (OR 14.13; p = 0.0001), and a Koval 2-3 (OR 12.84; p = 0.001) were identified as risk factors for this impairment. Conclusion Ambulation impairment at one year was 28.5%. The predictive characteristics found in this study help to identify patients with a greater risk of ambulation impairment and to focus rehabilitation plans to reduce this impact.

Tri-Lock Bone Preservation Stem Versus Conventional Corail Stem in Primary Total Hip Arthroplasty via Direct Anterior Approach: A Short-Term, Retrospective, Comparative Study. Med Sci Monit 2023; 29:e939635. [PMID: 37062914 PMCID: PMC10120384 DOI: 10.12659/msm.939635] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2023] [Accepted: 03/16/2023] [Indexed: 04/07/2023] Open
Abstract
BACKGROUND he present study was performed to evaluate the clinical efficacy of Tri-Lock bone preservation stems vs conventional Corail stems in primary total hip arthroplasty via direct anterior approach. MATERIAL AND METHODS In this retrospective analysis, patients receiving THA via DAA in a single-center hospital from January 2019 to March 2020 were assessed for eligibility and assigned to either a Tri-Lock BPS group or a Corail group based on the use of prostheses. Outcome measures for the efficiency evaluation of the 2 prostheses included perioperative outcomes, imaging results, Harris Hip Score, Western Ontario and McMaster University Osteoarthritis Index, and visual analog scale scores at 3, 6, 12, and 24 months postoperatively. RESULTS A total of 204 patients were included, including 98 patients (98 hips) in the Tri-Lock BPS group and 106 patients (106 hips) in the Corail group. Patients receiving Tri-Lock BPS exhibited better pain relief than those with Coral stems. Tri-Lock BPS had a higher safety profile vs Corail stems by significantly reducing the risk of complications (P=0.004). A markedly increased HHS score (84.42±16.27 vs 78.61±12.78, P=0.002) and a lower WOMAC score (25.08±15.39 vs 32.14±11.56, P=0.001) at 3 months postoperatively were observed in patients with Tri-Lock BPS vs those with Corail stems, indicating better restoration of hip function using Tri-Lock BPS. CONCLUSIONS During total hip arthroplasty via DAA, Tri-Lock BPS causes a smaller surgical wound, reduces the operative time and intraoperative bleeding, and produces less soft-tissue damage vs Corail stems, providing great benefits in femoral prosthesis placement.

Zoledronic Acid Does Not Retard Bone Union: A Randomized Controlled Trial in Fragility Intertrochanteric Femur Fractures. Cureus 2023; 15:e33948. [PMID: 36819363 PMCID: PMC9937685 DOI: 10.7759/cureus.33948] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 01/18/2023] [Indexed: 01/20/2023] Open
Abstract
BACKGROUND Fragility hip fracture is a leading cause of death in the elderly and is common in postmenopausal women and elderly people. In the treatment of osteoporosis, bisphosphonates (BPs) are often considered first-line medications. Zoledronic acid is the most potent and long-acting BP in clinical use and is administered as an intravenous infusion. In the context of acute fractures, the use of BPs has been controversial due to conflicting reports of their positive and negative effects on fracture healing. The purpose of this study was to determine the effect of zoledronic acid on fracture healing in intertrochanteric (IT) fragility fractures. METHODS The study was conducted in a tertiary healthcare center after receiving scientific and ethical approval. The study included 136 patients of either gender over the age of 50 who presented with an IT femur fracture after minor trauma between November 2020 and November 2022. The total number of patients had been classified into two groups, and grouping involved random sampling: Group T (test group, n = 68; zoledronic acid injections were given on postoperative day 3) and Group C (control group, n = 68; interventions were given after fracture healing). Patients were evaluated using the Radiographic Union Score for Hip (RUSH) and Singh Index for radiological outcomes and the Harris Hip Score (HHS) for functional outcomes. The patients were followed for six months. RESULTS The overall mean age was 73.25 years; in Group T, it was 72.5 ± 11.9 years, and in Group C, it was 73.7 ± 11.8 years. Of 136 patients, 69 (51%) were males and 67 (49%) were females. The average fracture healing time in Group T was 12.2 ± 3.6 weeks, while it was 13.0 ± 2.8 weeks in Group C. Functional outcomes, including HHS, were found to be better in Group T than in Group C (p < 0.005). No significant difference was observed between the two groups with respect to the radiological union, the RUSH score, or Singh Index, implying no negative effect of zoledronic acid. CONCLUSIONS This study demonstrates that postoperative intravenous zoledronic acid therapy does not retard fracture healing. Osteoporosis management is frequently neglected because of a surgeon's fear of ZOL retarding fracture healing and a lack of awareness among patients, resulting in low compliance. Thus, opportunistic administration of zoledronic acid postoperatively can be beneficial and will increase compliance for osteoporosis management and fracture prevention to 100%.

Abstract
BACKGROUND The purpose of the present study was to update and report clinical outcomes and survival of primary total hip arthroplasty using a cementless double-tapered titanium fully hydroxyapatite-coated stem at a follow-up > 30 years. METHODS The outcomes of this series of 347 primary total hip arthroplasties were already published at a follow-up > 25 years, during which only 12 stems were revised. Since then, there were two additional stem revisions, bringing the total to 14 stem revisions (all of which also required cup revision). Patients still living with the original stem were assessed using the modified Harris Hip Score and patient satisfaction (very satisfied, satisfied, dissatisfied, and very dissatisfied). Revision incidence was calculated using the Kaplan-Meier (KM) method and Cumulative Incidence Function (CIF) at 35 years. RESULTS At a mean follow-up of 33 years (range, 31 to 35 years), 32 patients (34 hips) were still living with the original stem. Their mean modified Harris Hip Score was 86 points (range, 46 to 100) and all patients (100%) were very satisfied or satisfied with surgery. The revision incidence at 35 years considering (a) stem revision for any reason was 9.5% using KM and 4.5% using CIF; (b) stem revision for aseptic loosening was 3.1% using KM and 2.1% using CIF; and (c) reoperation or revision of any component for any reason was 45.3% using KM and 26.3% using CIF. CONCLUSION The present study has demonstrated excellent survival at 35 years for a cementless double-tapered titanium fully hydroxyapatite-coated stem.

Validity and Reliability of the Thai Version of the Modified Harris Hip Score for Patients With Hip Abnormalities. Orthop J Sports Med 2022; 10:23259671221141095. [PMCID: PMC9743021 DOI: 10.1177/23259671221141095] [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: 08/29/2022] [Accepted: 09/15/2022] [Indexed: 12/13/2022] Open
Abstract
Background: The modified Harris Hip Score (mHHS) is one of the more commonly used patient-reported outcome measures to evaluate and monitor treatment in patients with hip abnormalities and has been translated into several languages. Purpose: To develop a Thai version of the mHHS (TH-mHHS) and evaluate the validity and reliability of the measure. Study Design: Cohort study (diagnosis); Level of evidence, 3. Methods: The TH-mHHS was developed using the forward-backward translation method. Patients who presented with hip pain during the first clinic visit completed the Thai version of questionnaires including the mHHS, 36-item Short Form Health Survey (TH-SF36), and Hip disability and Osteoarthritis Outcome Score (TH-HOOS). The validity between the measures was tested using the Spearman correlation coefficient. The test-retest reliability of the TH-mHHS was assessed using the intraclass correlation coefficient, and internal consistency was assessed using the Cronbach alpha. Results: A total of 64 patients were enrolled who had a mean age of 52.8 ± 16.6 years (range, 17-80 years). There were 64% female and 36% male participants. The TH-mHHS showed a moderate correlation with all subscales of the TH-HOOS and the total TH-HOOS ( r = 0.50-0.65; P < .01) and a high correlation with the physical functioning subscale and physical component summary of the TH-SF36 ( r = 0.73 and 0.75, respectively; P < .01). The test-retest reliability was excellent, with an intraclass correlation coefficient of 0.95 (95% CI, 0.92-0.97; P < .001). The internal consistency was acceptable, with a Cronbach alpha of .71. No floor or ceiling effects were observed. Conclusion: The TH-mHHS showed a moderate to high correlation with the TH-SF36 and TH-HOOS, excellent test-retest reliability, and acceptable internal consistency. This measure can be effectively used for evaluating Thai patients with hip disorders, especially an older and arthritic population.

Abstract
Introduction and aims There is paucity of prospective studies on conversion total hip arthroplasty (CTHA) for failed proximal femoral nailing. The objective of this study is to evaluate the functional outcome of CTHA using extensively porous coated distal loading stem for failed proximal femoral nailing. Patients and methods Fifteen consecutively operated patients for failed proximal femoral nail treated with single stage procedure of nail extraction and CTHA were included in this prospective observational study. All patients received metal-on-polyethylene bearing with uncemented press-fit acetabular cup (Pinnacle cup; DePuy, Warsaw [IN], USA) and extensively porous coated distally loading revision stem (Solution stem; DePuy, Warsaw [IN], USA). All patients were assessed preoperatively and postoperatively at one, three, six and more than twelve months using the Harris Hip Score (HHS). The responsiveness of HHS was assessed using Effect Size (ES) and Standardised Response Mean (SRM). ES and SRM >0.8 indicates adequate responsiveness. Results The mean duration of follow-up was 16.9 months for the overall cohort (SD: 7.9; range: 6-28 months). The mean preoperative HHS was 32 ± 6.1, the mean HHS at six months follow-up was 89.7 ± 4.0 and the mean HHS at final follow-up of atleast one year was 93.7 ± 3.0. There was a statistically and clinically significant improvement in the HHS from preoperatively to final follow-up postoperatively (p < 0.0001). At the final follow-up, twelve patients (80%) had an excellent outcome and three patients (20%) had a good outcome as per HHS grading. The ES was 9.87 and the SRM was 8.86 thereby suggesting adequate responsiveness. One patient developed surgical site infection and another patient developed dislocation. Both were successfully treated and subsequently the patients made uneventful recovery. None of the patients required revision surgery. Conclusion HHS has adequate responsiveness for assessing the functional outcome of CTHA. We recommend the use of an uncemented cup and uncemented extensively porous coated, distal loading stem for failed PFN fixation in intertrochanteric hip fractures.

Reducing Complications and Enhancing the Functional Outcome of Total Hip Arthroplasty without Increasing Operation Time by Repairing Posterolateral Soft Tissues. CONTRAST MEDIA & MOLECULAR IMAGING 2022; 2022:8364423. [PMID: 36176926 PMCID: PMC9499770 DOI: 10.1155/2022/8364423] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/08/2022] [Revised: 08/11/2022] [Accepted: 08/18/2022] [Indexed: 11/30/2022]
Abstract
Total hip arthroplasty (THA) surgeries are increasing annually. Despite continuous improvements in the surgical technique and prosthetic design, there is still no consensus on whether it is beneficial to reconstruct the posterolateral soft tissue. This paper systematically reviews randomized controlled trials (RCTs) addressing the efficacy and safety of posterolateral soft tissue during total hip replacement to provide evidence-based guidance for clinical practice. We searched PubMed, EMBASE, Cochrane Library, CNKI, and Wanfang databases for RCTs. Experimental results show that repair of the posterolateral soft tissue can reduce complications and improve the function of total hip arthroplasty without increasing operative time.

Abstract
PURPOSE We assessed acetabular erosion, hip function, quality of life (QoL), pain, deep infection, mortality, re-operation and dislocation rates in patients with displaced femoral neck fractures (dFNFs) treated with unipolar versus bipolar hemiarthroplasty at different postoperative time points. METHODS Relevant Randomized Controlled Trials (RCTs) were identified, following comprehensive literature research in Medline, Cochrane Central and Scopus databases, from conception until August 31th, 2021 and analyzed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. RESULTS Database research retrieved 120 studies; sixteen met eligibility criteria, providing 1813 (1814 hips) evaluable patients. Acetabular erosion was significantly higher for unipolar group at 6 and 12 months (p = 0.02 and p = 0.01 respectively). Patients in the bipolar group presented significantly better hip function at 12 and 24 months (p = 0.02 and p = 0.04 respectively). Postoperative pain was significantly less in the bipolar group at 12, 24 and 48 months (p = 0.01). No statistically significant differences were found regarding the postoperative rates of deep infection, mortality, re-operation and dislocation. CONCLUSION This study showed that patients with dFNFs treated with bipolar hemiarthroplasty have lower acetabular erosion rates at 6 and 12 months postoperatively, better hip function at 12 and 24 months, better QoL and less pain, when compared with unipolar. No statistically significant difference could be established regarding deep infection, mortality, re-operation and dislocation rates.

Abstract
Objective The aim of the present study was to compare functional results after Cemented Calcar replacement vis-a-vis Long stem Cemented hemiarthroplasty in patients aged more than 80 years with unstable intertrochanteric fractures. Methods The present prospective, randomized trial included 140 patients with AO/OTA type 31-A2, A3 intertrochanteric femur fracture, randomized into 2 treatment groups and followed-up for a minimum of 2 years. Sixty-seven patients in group A were treated with a cemented calcar replacing prosthesis, and 65 patients in group B were treated with a cemented long stem femoral stem prosthesis. The primary end points were hip functions at 2 years. The secondary end points were the complications encountered, mortality, surgical time, reoperation, blood loss, and activities of daily living. Results There were no major differences between the groups in terms of hip function, quality of life (health related), reoperation, mortality, and blood loss. However, the function in hip joint and activities of daily living deteriorated in both groups in comparison with prefracture levels. Conclusion In octogenarians with an unstable intertrochanteric fracture, cemented calcar replacing prosthesis has similar clinical results in comparison with long stem cemented hemiarthroplasty. Hemiarthroplasty with either implant is a good option in this subset of patients. Level of evidence: I.

Mismatch of short straight proximal femur nails with anterior bow of femur in Indian population- A radiological and functional analysis. J Orthop 2022; 29:65-70.

Abstract
INTRODUCTION Intra-medullary devices are the most common mode of fixation of inter-trochanteric fractures. Short proximal femur nails (PFN) used for fixing these fractures, unlike the long nails, are non-anatomic and are usually straight with no curvature in antero-posterior plane. As a result, there is always a chance of the nail tip impinging against the anterior cortex of femur. MATERIALS AND METHODS A total of 80 patients with trochanteric fractures (AO 31A2 and 31A3), operated with short PFN, were followed up retrospectively and prospectively from 2019 to 2021, for a period of 6 months. All fractures were fixed with PFNs, with nails ranging from 170 to 250 mm. Radiological analysis was done on hip lateral X-rays (taken at 6 months) using Angle at Distant Axis (ADA) and Nail Tip Position (NTP). Functional outcome analysis was done using Harris Hip Score. Patients were graded into 2 groups according to ADA (ADA>4° and ADA<4°). Incidence of anterior thigh pain was noted in patients on follow up and was statistically evaluated with nail size, nail diameter, ADA and NTP. RESULTS Mean ADA was 4.19° ± 1.45; mean NTP grade was 1.98 ± 1.11. Mean nail size was 201.87 mm with a mean nail diameter of 9.76 mm. Twenty patients complained of anterior thigh pain on follow-up. Twenty-five patients had NTP grade 3 or above of which 16 complained of anterior thigh pain (p < 0.001). Fifty-five patients had nail diameter of 10 mm or above of which 14 had anterior thigh pain (p < 0.01). Fifty-three patients had a nail length of 200 mm or above of which 16 patients complained of thigh pain on follow up (p < 0.01). CONCLUSION There is a mismatch of short PFNs with anterior bow of femur. Use of shorter nails with narrow diameters will avoid this mismatch to an extent.

Abstract
INTRODUCTION Inadequate stem version might lead to impingement and instability after cementless total hip arthroplasty (THA). We evaluated (1) the distribution of short-stem anteversion, (2) the proportion of stems with an anteversion less than 5° or larger than 25°, (3) combined cup and stem anteversion, and (4) dislocation rate. MATERIALS AND METHODS We evaluated the native femoral anteversion and stem anteversion in 340 patients (340 THAs): 144 men and 196 women. Their mean age was 56.2 (22-87) years and mean body mass index was 25.1 (15.2-40.7) kg/m2. The femoral neck anteversion was measured on pre-operative CT scan and the stem anteversion was obtained during the operation. The safe zone of the stem anteversion was defined as 5 to 25°. RESULTS The femoral neck anteversion ranged from -15 to 61° (mean, 15.0°; SD, ±10.6°). The stem anteversion ranged -7 to 50° (mean, 15.7°; SD, ±9.5°). It was optimal (5-25°) in 71.2% (242/340), insufficient (<5°) in 13.3% (45/340), and excessive (>25°) in 15.6% (53/340). The stem anteversion had a medium correlation with the femoral neck anteversion (correlation coefficient = 0.449). The combined anteversion was 42.0° (range, 35.2-52.3°; SD, ±2.8°). During two to four year follow-up, no hip dislocated. CONCLUSIONS Short-length stem had a great variability in the anteversion and considerable portion (28.9%, 98/340) of stems had an anteversion outside the safe zone. Surgeons should be aware of this variability of stem anteversion to compensate for abnormal stem anteversion, which might lead to impingement and instability after THA.

Fixation of intertrochanteric femur fractures using the SIGN intramedullary nail augmented by a lateral plate in a resource-limited setting without intraoperative fluoroscopy: assessment of functional outcomes at one-year follow-up at Juba Teaching Hospital. OTA Int 2021; 4:e133. [PMID: 34746666 PMCID: PMC8568479 DOI: 10.1097/oi9.0000000000000133] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2020] [Revised: 02/17/2021] [Accepted: 04/02/2021] [Indexed: 12/01/2022]
Abstract
Objectives: The incidence of hip fracture is high and increasing globally due to an aging population. Morbidity and mortality from these injuries are high at baseline and worse without prompt surgical treatment to facilitate early mobilization. Due to resource constraints, surgeons in low-income countries often must adapt available materials to meet these surgical needs. The objective of this study is to assess functional outcomes after surgical fixation of intertrochanteric femur fractures with the Surgical Implant Generation Network (SIGN) intramedullary nail augmented by a lateral SIGN plate. Design: Prospective case series Setting: Juba Teaching Hospital, Tertiary Referral Hospital for South Sudan Participants: Adult patients with intertrochanteric hip fractures Intervention: SIGN nail augmented by a lateral plate Main Outcome Measurements: Primary outcome was hip function as measured by a modified Harris Hip Score (mHHS) at 1-year after surgery. Secondary endpoints were the occurrence of reoperation or infection at 1-year after surgery. Results: Thirty patients were included, 16 (53%) men and 14 (47%) women, with a mean age of 62 years. Fractures were classified as AO/OTA Type 31A1 in 12 (40%) patients, 31A2 in 15 (50%) patients, and 31A3 in 3 (10%) patients. Mean mHHS at 1-year was 75.10 ± 21.2 with 76% categorized as excellent or good scores. There was 1 (3%) infection and 2 (7%) reoperations. Conclusions: The SIGN nail augmented by a lateral plate achieved good or excellent hip function in the majority of patients with intertrochanteric hip fractures. This may be a suitable alternative to conventional implants for hip fracture patients in low-resource settings to allow mobilization.

Outcome of unstable pertrochanteric fractures in high-risk geriatric treated with external fixators. EUROPEAN JOURNAL OF ORTHOPAEDIC SURGERY AND TRAUMATOLOGY 2021; 32:867-874. [PMID: 34155571 DOI: 10.1007/s00590-021-03066-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/15/2021] [Accepted: 06/17/2021] [Indexed: 11/27/2022]
Abstract
PURPOSE To review the outcome of high-risk geriatrics with unstable pertrochanteric fractures treated with external fixator. METHODS Eighteen consecutive patients with pertrochanteric fractures were operated with external fixator by using closed reduction technique. AO type, accompanying diseases, operating time, transfused blood units, duration of hospitalization, complications, healing time and mortality were recorded. Patients were followed clinically and radiologically for two years at least. The Harris Hip Score was used to document hip function at each regular follow-up. RESULTS Fifteen patients with average age of 71.5 years were available for final evaluation. The mean operating time was 41.1 min and union was achieved in all cases with an average time of 16 weeks. The mean Harris Hip Score at one, three, six, twelve and twenty-four months post-operatively was 42.07 ± 8.55; 55.07 ± 11.62; 70.07 ± 10.32; 86.27 ± 9.06 and 89.27 ± 8.81 respectively. Complications included all the patients undergoing loss of some motion in the knee and four of them had to experience revision surgery because of knee stiffness, ten cases of pin-tract infections, seven cases of deep venous thrombosis, two cases of migration of the screws and two cases limb shortening. CONCLUSIONS The use of external fixator in high-risk geriatric provided a satisfactory long-term efficacy, but the short-term functional results were quite unsatisfactory owing to high complication rate. Therefore, the advantages and disadvantages should be fully weighed when using external fixators, which was especially suitable for those patients who could not tolerate prolonged operative time and open surgery. LEVEL OF EVIDENCE IV Therapeutic study, level 4.

Abstract
Hip fractures in elderly are commonly associated with osteoporosis and surgical outcome is influenced by its concurrent management. The purpose of our study is to determine the association between timing of bisphosphonate administration in inter-trochanteric (IT) fractures and fracture healing. Patients with IT fractures (aged≥50 years) and T-score ≤ -1.5 [WHO defines osteopenia as T-score between -1 and -2.5, and osteoporosis as T-score ≤ -2.5 on DEXA scan (which was obtained post-operatively in our cohort)], who underwent proximal femoral nailing were included. Patients were divided into three groups: group 1a-intravenous bisphosphonate {ivBP [zoledronic acid (ZA)]} given within one week, group 1b-ZA at six weeks and group 2-control group. Post-operative radiographs were assessed for reduction parameters [neck-shaft angle, tip-apex distance, reduction variance]. Radiological union was determined using RUSH score and functional outcome (at one year) with Modified Harris Hip Scores. 41 (23 males), 40 (15 males) and 42 (15 males) patients were included in groups 1a, 1b and 2, respectively (no statistical difference in sex distribution among the groups; p = 0.12). Mean age in groups 1a, 1b and 2 was 71.8 ± 8.1, 75.9 ± 8.5 and 72.3 ± 10.6 years (p = 0.09). There was no significant difference in the pattern of injuries (AO classification) among the groups (p = 0.72). Mean time to union in groups 1a, 1b and 2 was 13.7,13.7 and 14.2 weeks, respectively (p = 0.69). Mean time to union in AO types A1, A2 and A3 fractures was 13.2 ± 2.1, 13.7 ± 2.8 and 16.1 ± 4.9 weeks (p = 0.01). We did not observe any association between T-scores and fracture union (hip:p = 0.52, spine:p = 0.93).The functional outcome was similar among groups (p = 0.96). Early administration of ZA did not negatively influence fracture healing in patients undergoing fixation of IT fractures. Among the various other factors analyzed, there was a statistically significant association between the fracture type (AO type A3) and longer time to fracture union.

Abstract
Background Interlocking intramedullary nail is used for almost all types of femoral shaft fractures worldwide because of its better mechanical stability. In countries like India with limited healthcare infrastructure, the use of Kuntscher nail (K-nail) in Winquist type I and type II isthmic fractures is still debated. Therefore, we conducted this study to compare the functional outcome, radiation exposure, and cost of the implant between closed reduction and internal fixation of Winquist type I and II fractures in the middle one-third shaft region by K-nail and intramedullary locked nails (IMILN), respectively. Methods This was a hospital-based non-blinded randomized trial which included 56 patients with closed Winquist type I and II femoral shaft fractures of the middle one-third femoral shaft (isthmic and paraisthmic zone). All the patients were either treated by K-nail or IMILN. The patients were followed up every three weeks for the initial six months and quarterly thereafter. Per operative duration of surgery and radiation exposure by C-arm was documented and assuming scattered radiation 20%, radiation exposure to the surgeon was calculated and patients were assessed clinically and radiologically for union. Results The patients were divided into two groups: group I (K-nail, n = 25) and group II (IMILN, n = 31). In groups I and II, the patients achieving radiological union were 88% (n = 22/25) and 84% (n = 27/31) at six months’ duration, respectively. The mean duration for the radiological union was 3.65 ± 0.55 months in group I (K-nail) and 3.76 ± 0.59 months in group II (IMILN), respectively. There was no statistically significant difference in the duration of the union (p = 0.4963). The average number of C- arm exposures was 16.36 ± 3.18 in group I as compared to 27.29 ± 4.01 in group II, and the mean scattered radiation was 5.0 ± 1.63 in group I and 6.61 ± 4.06 in group II. This difference was statistically significant. Conclusion Kuntscher intramedullary nailing can provide comparable rates of union as is achieved with interlocking intramedullary nailing with an advantage of less radiation exposure and duration of surgery, provided the patient selection is proper (isthmic and paraisthmic zone).

Abstract
BACKGROUND Objective of the study was to evaluate and compare psychometric properties such as validity, reliability, floor ceiling effects and interpretability of the modified Harris Hip Score (mHHS) and the Forgotten Joint Score (FJS) in patients undergoing bipolar hemiarthroplasty for femoral neck fracture in Indian patients, because this has not been done before. METHODS This observational study consisted of 40 consecutively operated patients. Construct validity and reliability were evaluated using correlation coefficient and Intraclass correlation coefficient (ICC), respectively. Interpretability was evaluated by describing mean and standard deviation of mHHS and FJS in five subgroups of patients based on their response to the global rating questions and assessment. RESULTS The mean follow-up duration was 15.7 months ± 10.4. There was very high correlation between mHHS and FJS (r = 0.92, p < 0.0001) suggesting convergent construct validity. The results of correlation coefficient were 100% and 66.7% in accordance with the pre-formulated hypotheses for mHHS and FJS, respectively. mHHS and FJS demonstrated adequate construct validity and inadequate construct validity, respectively. The ICC value for mHHS and FJS was 0.80 (p = 0.005) {adequate reliability} and 0.34 (p = 0.06) {inadequate reliability}, respectively. Both mHHS and FJS-12 demonstrated acceptable level of floor (0% for mHHS and 14.3% for FJS) and ceiling effects (12.5% for both mHHS and FJS). There was significant difference in the mHHS and FJS in the five subgroups of patients suggesting adequate interpretability. CONCLUSION We recommend the use of the modified Harris Hip Score over the Forgotten Joint Score for functional outcome evaluation of Indian patients from rural setting undergoing bipolar hemiarthroplasty for femoral neck fracture.

Abstract
Background and aim of the work: The worldwide incidence of fractures of the proximal end of the femur is increasing as the average age of the population rises. The current surgical gold treatment standard is intramedullary nail fixation. The Authors present their experience with the D-Nail system for intertrochanteric femur fractures. Methods: From January 1st to February 21st 2020 (breakout of COVID-19 pandemic) 34 patients were treated with the D-Nail system: 11 with basicervical fractures, 16 with intertrochanteric stable fractures and 7 with intertrochanteric unstable fractures. In 11 cases, a single cephalic screw was used; in 23 cases, two of them were used. Distal locking was executed in 7 patients. Follow-up time ranged from 2 to 3 months. Results: None of the reported intra- or post-operative complication was linked to the fixation device or the surgical technique. Patients were monitored with clinical and radiological checkups using modified Harris Hip Score to accurately evaluate the fluctuations in the rehabilitation period. Conclusion: The main advantages of this synthesis device are the proximal hole’s peculiar shape, which allows the possibility to position one or two cephalic screws on the same nail, and the silicon coating, which provides numerous biological advantages. Distal locking was executed in selected cases only, based on fracture type. Optimum treatment involves rapid execution of surgery, minimal trauma during surgery, maximum mechanical stability, and rapid weight-bearing. Although our case number is small and follow-up time brief, our results are encouraging. (www.actabiomedica.it)

The Results of Unstable Intertrochanteric Femur Fracture Treated with Proximal Femoral Nail Antirotation-2 with respect to Different Greater Trochanteric Entry Points. Adv Orthop 2020; 2020:2834816. [PMID: 32280544 PMCID: PMC7142344 DOI: 10.1155/2020/2834816] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/25/2019] [Accepted: 03/03/2020] [Indexed: 11/18/2022] Open
Abstract
Background Proximal femoral nail antirotation-2 (PFNA-2) has been widely used to treat intertrochanteric fractures with varied outcomes in the previous studies. The entry point of the nail plays an important role in achieving acceptable reduction, stable fixation, and avoiding implant related complications. This study was proposed to determine the optimal greater trochanteric entry point for PFNA-2 in unstable intertrochanteric femur fractures. Methods We conducted an observational study on 40 patients with unstable intertrochanteric fracture treated with PFNA-2 implant in a tertiary care hospital. The patients were grouped into two based on the entry point: group L for lateral and group M for medial entry. Randomization was carried out by assigning the patients to the group by alternate allocation. The quality of reduction, tip apex distance, Cleveland index, and all the complications were noted. The final follow-up was conducted at six months. The functional outcome was evaluated using modified Harris hip score. The data analysis was performed using Student's t-test, chi square test, and Mann–Whitney test. A P value below 0.05 was considered significant. Results Forty patients with 20 patients treated with medial entry point were included in group M and 20 patients in group L with lateral entry point. The group L had an average tip apex distance of 20.53 and group M had 20.02 (P=0.8). The complication of screw back out was seen in 3 out of 4 patients with poor reduction in group L. As per the Cleveland index, 6 patients in each group had suboptimal position and 4 out of 6 patients in group L with suboptimal position had screw back out. The lateral cortex impingement was seen in 14 patients of group L and 6 patients in group M with significant comparison (P=0.01). Three patients in group L had varus collapse with screw back out. Also, none in group M (0.05). The average modified Harris hip score in group L at six months follow-up was 71.94 and 76.8 in group M (P=0.84). Conclusion Overall, to achieve good quality of fixation and reducing damage to gluteus medius entry point for PFNA-2 should be 5 mm medial to the greater trochanter tip.

Abstract
OBJECTIVE To evaluate clinical and radiological outcomes of proximal femoral nail anti-rotation (PFNA-II) devices and demonstrate the effectiveness of PFNA-II for the treatment of basicervical fractures in elderly patients. METHODS A retrospective review of all patients treated with PFNA-II for a proximal femoral fracture between January 2013 and February 2017 at three different institutions (Shanghai General Hospital, Shanghai Punan Hospital and Shanghai Seventh People's Hospital) was conducted. The X-ray films were strictly reviewed by three trauma surgeons and a professional radiology doctor. Patients over 60 years of age who met the following criteria were included: (i) sustained low-energy trauma; (ii) a two-part fracture; (iii) fracture line located at the base of the femoral neck and that was medial to the intertrochanteric line and exited above the lesser trochanter but was more lateral than a classic transcervical fracture. Follow-up time should be longer than 6 months. A total of 52 patients who met the inclusion criteria were selected. The average age at diagnosis was 75.1 years (range, 63-91 years); 13 patients were men and 39 were women. The same proximal femoral nail anti-rotation devices and the same surgical procedures were applied to all patients. Postoperative radiographic union time and modified Harris hip scores were used as major indicators for evaluating the effectiveness of surgery. RESULTS The average follow-up period was 22.5 months (18.5, 23.9, and 21.2 months, respectively) and radiographic unions were observed at an average of 19.6 weeks (range, 12-28 weeks). The patients were evaluated immediately after surgery, as well as 6 weeks, 3 months, 6 months, 1 year, and 2 years postoperatively. Of the 49 patients, 38 had good reduction qualities (75.5%), 9 acceptable (18.3%), and 3 poor (6.1%). Radiographic union was confirmed in all fractures at an average of 19.6 weeks (range, 12-28 weeks). The mean Harris hip score was 84.9 (range, 65-99): excellent in 9 patients (18.36%), good in 30 (61.22%), medium in 8 (16.32%), and poor in 2 (4.08%). Slight persistent pain occurred in 3 patients, but these patients could still walk with the help of a cane. Two patients had symptoms of excessive telescoping. Eight patients experienced postoperative medical complications, mainly pneumonia and urinary tract infection. CONCLUSION Based on the clinical and radiological outcomes, the PFNA-II devices provide strong rotational stability and excellent clinical prognosis, and are an appropriate treatment option for basicervical proximal femoral fracture in elderly patients.

Abstract
Background The elderly population is prone to hip fractures, and treating such patients to achieve good outcomes can be challenging. Collection of outcomes data can support clinicians to modify their treatment protocols and improve outcomes over time. The aim of this study is to compare different surgical procedures in patients with neck of femur and intertrochanteric fractures in terms of clinical, functional and radiological outcomes using injury-specific outcome scores. Methods The study data was derived from the existing single-center, prospective orthopaedic trauma registry initiated from July 2015. Functional, clinical and radiological outcomes were assessed using Modified Harris Hip Score and The Radiographic Union Score for Hip. Mean radiological outcome scores was compared by Mann-Whitney U test and deaths by Chi-square and Odds ratio. Results Of the total 138 patients, 53 (38%) were neck of femur and 85 (62%) Intertrochanteric fractures with fall as leading cause of injury. At 12 months follow-up, modified Harris Hip Score showed 67% excellent-good results in both dynamic hip screw (N = 6) and total hip replacement (N = 3) followed by 50% in intramedullary nail (N = 2). Hemiarthroplasty has fair-poor outcomes with significantly higher deaths as compared to other procedure groups (p = 0.016). Radiological outcomes showed non-significant trend towards better outcomes in dynamic hip screw as compared to intramedullary nail (p = 0.08). Conclusion Our 12 months follow-up data suggest that dynamic hip screw and total hip replacement have better clinical, functional outcomes followed by intramedullary nail. Hemiarthroplasty has fair-poor clinical and functional outcomes with significantly higher deaths as compared to other procedure groups. To compare different surgical procedures in patients with neck of femur and intertrochanteric fractures in terms of outcomes. A Single center, prospective cohort study. Dynamic hip screw, total hip replacement, intramedullary nail, hemiarthroplasty. Functional, clinical and radiological outcomes assessment using Modified Harris Hip Score and The Radiographic Union Score. At 12 months, DHS and THR have better outcomes. Hemiarthroplasty has significantly higher deaths as compared to other groups.

Abstract
Introduction The implant of choice for two-part intertrochanteric femur fracture is still under debate. This study was done to compare the operative parameters and functional outcome of two-part intertrochanteric fractures treated by dynamic hip screw (DHS) and proximal femur nail (PFN). Methods Fifty-four operated cases of two-part intertrochanteric (AO 31A1) were analysed and divided into two groups based on implant used (PFN 30, DHS 24). Operative details, which include blood loss and duration of surgery, were obtained from hospital records. All patients were followed up for six months and assessed for radiographic and functional outcome. The functional outcome was calculated with modified Harris hip score and Parker mobility score. Results There was no significant difference in the operative parameters (p > 0.05) between DHS and PFN. The average blood loss for DHS and PFN was 202.5 ml and 198 ml respectively while operative duration was 136 min and 126 min, respectively. All patients had good functional outcome at the end of six months with average Harris hip score of 69.7 and Parker score of 8. No difference was found between the two surgeries in terms of functional outcome as well (p > 0.05). Conclusion There is no conclusive evidence to show that PFN is superior to DHS in the treatment of two-part intertrochanteric (31A1) fracture. Both DHS and PFN are equally effective in treatment of such fractures.

Comparison of radiological and functional outcome of unstable intertrochanteric femur fractures treated using PFN and PFNA-2 in patients with osteoporosis. EUROPEAN JOURNAL OF ORTHOPAEDIC SURGERY AND TRAUMATOLOGY 2019; 29:1035-1042. [PMID: 30778679 DOI: 10.1007/s00590-019-02401-x] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/19/2018] [Accepted: 02/12/2019] [Indexed: 12/27/2022]
Abstract
INTRODUCTION Presently, unstable intertrochanteric femur fractures are treated commonly with intramedullary nailing devices. Various designs of intramedullary nail are introduced. The conventional Proximal Femoral Nail has given diverse outcome. Complications have also been noted with this implant. Newer designs like Proximal Femoral Nail Antirotation-2 have been introduced for Asian population. The aim of our study was to compare the radiological and functional outcome of unstable intertrochanteric femur fracture treated with conventional Proximal Femoral Nail and Proximal Femoral Nail Antirotation-2 in osteoporotic patients. MATERIALS AND METHODS Patients presenting with unstable intertrochanteric femur fracture (AO classification) and Singh's index ≤ 3 were included. Patients were assigned to the groups based on the implant used for treatment (PFN and PFNA2 group). Post-operative radiographs were used to assess the quality of reduction, by calculating neck shaft angle. The quality of fixation was assessed, by calculating tip apex distance and Cleveland index. The duration of surgery, blood loss, number of fluoroscopic images taken and length of hospital stay were noted. Patients were followed up for 6 months, and complications were noted. The functional outcome was compared using modified Harris hip score. The data analysis was done using Student's unpaired t test/Mann-Whitney U test and Chi-square test/Fisher's exact test. A p value less than 0.05 was considered significant. RESULTS Seventy-eight patients with unstable intertrochanteric fractures and Singh's index < 3 were included. Thirty-seven were treated with PFNA2 and 41 with PFN. The average age in PFNA2 group was 69.51, and PFN group was 70.804. Nine patients in PFNA2 group and 10 patients in PFN group had tip apex distance more than 25 mm. Twelve patients in PFNA2 group and 14 Patients in PFN group had sub-optimal implant position as per Cleveland index. The difference in neck shaft angle between uninjured and operated side was more than 10° in four patients of PFNA2 group and seven patients of PFN group. The average Harris hip score was 74.55 for PFNA2 group and 69.88 for PFN group. Four complications were seen in PFNA2 group and 5 in PFN group. CONCLUSION The functional outcome (p = 0.102) achieved with both the implants was similar. Good functional outcome can be achieved, when the radiological parameters are restored, i.e. TAD < 25 mm, Cleveland index in centre-centre position and neck shaft angle difference < 5°. The overall complications, in the set-up of osteoporosis, seen with both the implants were similar (p = 0.44). PFNA2 group showed better results in terms of perioperative morbidity.
