Clinical outcomes of total joint arthroplasty in patients with bowel ostomies.

INTRODUCTION: The influence of prior colostomy or ileostomy on patients undergoing joint arthroplasty remains poorly understood. Our study aimed to assess whether patients with an ostomy undergoing hip and knee arthroplasties have worse postoperative outcomes and increased rates of revisions. METHOD: A single-center, retrospective review of patients with a history of bowel ostomy who underwent a primary total hip arthroplasty (THA), hemiarthroplasty (HA), and total knee arthroplasty (TKA) from 2012 to 2021. A total of 24 THAs, 11 HAs, and 25 TKAs in patients with open small or large bowel stoma were identified. A ten-to-one propensity score match was utilized to establish cohorts with comparable demographics but no prior ostomy procedure. RESULTS: Patients with stomas undergoing elective THA showed greater 90-day ED visits (20.0 vs. 5.0%, P = 0.009), 90-day all-cause readmissions (20.0 vs. 5.0%, P = 0.009), 90-day non-orthopedic readmissions (10.0 vs. 0.5%, P < 0.001), 90-day readmissions for infection (5.0 vs. 0.5%, P = 0.043), all-cause revisions (15.0 vs. 0.5%, P < 0.001), revisions for PJI (5.0 vs. 0%, P = 0.043), and revisions for peri-prosthetic fracture (10.0 vs. 0%, P < 0.001). Patients with stomas undergoing non-elective hip arthroplasties exhibited a longer mean LOS (12.1 vs. 7.0 days, P < 0.001) and increased 90-day all-cause readmissions (40.0 vs. 17.3%, P = 0.034), 90-day orthopedic readmissions (26.7 vs. 6.0%, P = 0.005), all-cause revisions (13.3 vs. 2.0%, P = 0.015), revisions for peri-prosthetic fracture (6.7 vs. 0%, P = 0.002), and revisions for aseptic loosening (6.7 vs. 0%, P = 0.002). There were no significant differences in readmission or revision rates between ostomy patients undergoing TKA and a matched control group. CONCLUSION: Patients undergoing hip arthroplasties with an open stoma are at an increased risk of hospital encounters and revisions, whereas TKA patients with stomas are not at increased risk of complications. These findings emphasize the importance of recognizing and addressing the unique challenges associated with this patient population.

Total elbow arthroplasty and hemiarthroplasty in the treatment of distal humerus fractures in the elderly: Experience from a tertiary referral centre.

BACKGROUND: There is no clear consensus on whether total elbow arthroplasty (TEA) or hemiarthroplasty (HA) is superior for treating distal humerus fractures in the elderly. This study analysed the functional outcomes and re-operation rates following TEA and HA for intra-articular distal humerus fractures in patients aged ≥65 years. METHODS: 19 patients (TEA = 12, HA = 7) treated between 2016 and 2022 were retrospectively reviewed. Mean age was 73 years and mean follow-up was 46 months. Functional outcomes and quality of life were assessed using the Mayo Elbow Performance Score (MEPS), Quick-DASH (Q-DASH), Oxford Elbow Score (OES), SF-12 Physical Component Score (PCS) and Mental Component Score (MCS), and EQ-5D. Complications requiring re-operation were recorded. RESULTS: HA showed superior outcomes in MEPS (93.6 vs 75.0, p = 0.0339), Q-DASH (13.3 vs 31.3, p = 0.0182), OES (41.7 vs 33.2, p = 0.0346), SF-12 PCS (55.5 vs 36.9, p = 0.0008) and EQ-5D (83 vs 67, p = 0.0023). One HA patient required revision to TEA for prosthetic joint infection. One TEA patient required revision for a periprosthetic ulna fracture. CONCLUSION: HA provides better functional outcomes compared to TEA in the treatment of distal humerus fractures in the elderly. Data is limited by selection bias and low patient numbers with a multicentre randomised controlled trial warranted.

Conversion of a Failed Hip Hemiarthroplasty to Total Hip Arthroplasty: A Systematic Review and Meta-Analysis.

Background: Hip hemiarthroplasty (HA) and total hip arthroplasty (THA) are common treatments for femoral neck fractures in elderly patients. Despite HA's advantages of shorter operative times, less blood loss, and lower initial costs compared to primary THA, it may lead to conversion THA (cTHA). Our objectives are to evaluate the impact of conversion from HA to THA on Harris hip scores (HHS), compare complication rates between cTHA, revision THA, and primary THA, and assess the rates and types of complications following cTHA. Methods: A systematic review and meta-analysis were performed, evaluating studies published until 2023, with inclusion criteria entailing studies that explored outcomes and complications following cTHA of failed HA. Data extraction focused on variables such as postoperative HHS and complication rates, including periprosthetic joint infection, periprosthetic fracture, dislocation, stem loosening, acetabular loosening, and overall revision. Results: This study included 28 retrospective studies (4699 hips), showing a mean increase in HHS by 39.1 points, indicating a significant improvement from preoperative levels. Complication rates were detailed, with a 6.4% rate of periprosthetic joint infection, 2.2% for periprosthetic fracture, 7.6% dislocation, 1.6% stem loosening, 1.9% acetabular loosening, and an overall re-revision rate of 8.7%. Conclusions: Conversion from HA to THA generally results in improved functional outcomes, as evidenced by HHS improvements. Despite the positive impact on HHS, cTHAs are associated with notable risks of complications and the need for further revision surgeries. Level of Evidence: IV.

Adoption of Reverse Total Shoulder Arthroplasty for Surgical Treatment of Proximal Humerus Fractures Differs by Patient Race.

BACKGROUND: Reverse total shoulder arthroplasty (rTSA) has gained popularity for the operative treatment of proximal humerus fractures (PHF). The purpose of this study was to compare racial differences in surgical management of PHF between open reduction and internal fixation (ORIF), hemiarthroplasty, and rTSA. Our hypothesis was that there would be no difference in fixation by race. METHODS: The National Surgical Quality Improvement Program (NSQIP) database was queried for ORIF, rTSA, and hemiarthroplasty between 2006 and 2020 for patients with a PHF. Race, ethnicity, age, sex, body mass index (BMI), and American Society of Anesthesiologists (ASA) class were recorded. Chi squared tests were performed to assess relationships between patient factors and operative intervention. Factors significant at the 0.10 level in univariable analyses were included in a multivariable multinomial model to predict operative intervention. RESULTS: 7,499 patients underwent surgical treatment for a PHF, including 526 (7%) undergoing hemiarthroplasty, 5,011 (67%) undergoing ORIF, and 1,962 (26%) undergoing rTSA. 27% of white patients with PHF underwent rTSA compared to 21% of Black patients, 16% of Asian patients, and 14% of Native American and Alaskan Native patients (p<0.001). In the multivariable analysis, utilization of rTSA increased over time (OR 1.2 per year since 2006, p < 0.001) and hemiarthroplasty decreased over time (OR 0.86 per year since 2006, p < 0.001). Non-white patients had significantly lower odds of undergoing rTSA versus ORIF (OR 0.75, 95% CI 0.58-0.97), as did male patients (OR 0.77, 95% CI 0.66-0.88). Patients over 65 (OR 3.86, 95% CI 3.39-4.38), patients with higher ASA classifications (ASA2: OR 3.24, 95% CI 1.86-5.66, ASA3: OR 4.77, 95% CI 2.74-8.32, ASA4: OR 5.25, 95% CI 2.89-9.54), and patients who were overweight (OR 1.33, 95% CI 1.14-1.55) or obese (OR 1.52, 95% CI 1.32-1.75) had higher odds of undergoing rTSA versus ORIF. DISCUSSION: As utilization of rTSA increases, understanding disparities in surgical treatment of PHF is crucial to improving outcomes and equitable access to emerging orthopedic technologies. While patient factors such as age, BMI, and comorbidities are known to directly impact outcomes and thus may be predictive of the type of surgical intervention, patient race should not dictate treatment.

Hemoglobin level, degree of mobilization, and pneumonia are associated with the development of postoperative delirium in cemented hemiarthroplasty after femoral neck fracture.

PURPOSE: The aim of this retrospective study was to identify independent prognostic factors for developing a postoperative delirium (POD) in patients suffering from a proximal femoral neck fracture and treated by implantation of a hemiprosthesis. METHODS: A retrospective study, including patients with hip hemiarthroplasty due to a femoral neck fracture between 2011 and 2020 was performed. Demographic data, preexisting conditions, intra-/postoperative complications, mobilization and laboratory results were extracted from the patients' charts. The different parameters were analyzed comparing patients with and without POD. RESULTS: 412 patients, mean age of 81 ± 9.58 years were included, 66.5% (n = 274) were female, 18.2% (n = 75) of them developed a POD. Significantly higher incidence of POD was associated with older age (p < 0.001), lower level of haemoglobin (p < 0.001), higher post-surgery interleukin 6 (IL 6) level (p = 0.008), higher postoperative level of leukocytes (p = 0.01). Patients with POD received more units of packed red blood cells (PRBC) (p = 0.007). Patients with no mobility limitations pre-operatively developed POD less frequently (p = 0.01), whereas suffering from pneumonia (p = 0.03) or limited mobility postoperatively increased the risk of POD (p < 0.001). CONCLUSION: This study could help to identify patients with a risk for developing POD after a hemiarthroplasty in femoral neck fractures. As a consequence, frequent controls of Hb, IL 6 and leucocytes levels to avoid anemia and infections, as well as the well surgical treatment to guarantee a good postoperative outcome.

Concerns with alumina bipolar hemiarthroplasties compared to metal bipolar hemiarthroplasties when performed for nontraumatic osteonecrosis of the femoral head.

PURPOSE: A nationwide multicenter follow-up cohort study of hip replacement arthroplasties performed for nontraumatic osteonecrosis of the femoral head (ONFH) aimed to answer the following questions: What factors were associated with need for reoperation? Although many modifications were made in bipolar hemiarthroplasties (BPs) to improve their durability, could we find any evidence of their efficacy? METHODS: Excluding 58 infected hips and 43 ABS THAs with very poor survivorship, we analyzed 7393 arthroplasties; 6284 total hip arthroplasties (THAs), 886 BPs, 188 total resurfacing arthroplasties, and 35 hemi-resurfacing arthroplasties (hRSs). In the 886 BPs, 440 hips had a smooth small-diameter prosthetic neck (nBPs), 667 hips had a smooth neck (sBPs), 116 hips had highly cross-linked polyethylene in the outer head (hBPs), and 238 hips had an outer head whose outer surface was alumina ceramic (aBPs) (648 hips had an outer head whose outer surface was metal [mBPs]). Multivariate analyses using a Cox proportional-hazard model analyzed risk factors. RESULTS: Follow-up ranged from 0.1 to 27 (average, 6.9) years, during which 265 hips (3.6%) needed reoperation. Combined systemic steroid use and excessive alcohol consumption and lateral approach were associated with higher risks, aBPs were less durable than THAs or mBPs, and hRSs were inferior to the others. Regarding BPs, the following divisions did not influence their survivorship; nBP or not, sBP or not, and hBP or not. CONCLUSIONS: Factors associated with reoperation risk were identified as described above. The modifications made in BPs did not improve their durability, but aBPs made it worse. LEVEL OF CLINICAL EVIDENCE: Level III, therapeutic cohort study.

Cemented Bipolar Hemiarthroplasty as a Treatment Modality for Pathological Fracture in the Proximal Femur Metastasis Without the Recurrence of Primary Breast Cancer: A Case Report.

Metastatic lesions in the proximal femur are well-known in the literature and are important since they can progress to pathological fractures and impair the patient's mobility. We present the case of a middle-aged female with a history of breast carcinoma 20 years ago, who experienced diffuse chronic hip pain for the past two months. Radiographs, MRI, and PET scans revealed a metastatic lesion in her proximal femur. After consulting with an oncologist, it was determined that adjuvant chemoradiotherapy was unnecessary. The treatment strategy was dependent on the preoperative general health condition, the life expectancy, amount of metastasis, bone quality, pathological fractures and factors affecting the union and capacity to ambulate the patient postoperatively. The patient underwent a cemented bipolar hemiarthroplasty to excise all metastatic tissue and provide a painless, functional, and mobile joint. Bipolar hemiarthroplasties articulate at two levels, and this dual-bearing design is believed to reduce acetabular wear. The bipolar hemiarthroplasty also eliminated the risk of complications associated with the acetabular component, which would necessitate early revision surgery. Modular bipolar hemiarthroplasty is a good modality of replacement associated with fewer complications and improves quality of life.

Enhanced Surgical Techniques in Orthopedics: A Comprehensive Guide for Surgeons Based on Modification of the McFarland and Osborne Approach to the Hip.

INTRODUCTION: The implementation of various approaches in hip arthroplasties introduces distinct advantages and complications. Notably, widely adopted methods such as the posterior approach have been linked to elevated rates of posterior hip dislocations and iatrogenic sciatic nerve injuries, while the lateral approach has been associated with superior gluteal nerve injuries. In this study, we propose a refined modification of the McFarland and Osborne approach, aiming to amalgamate the most favorable aspects of prior modifications of the lateral approach to the hip. Additionally, our contribution extends to providing a comprehensive stepwise guide for the exposure and closure processes in cases of bipolar hemiarthroplasty or total hip replacement. This modification not only offers potential advantages to seasoned orthopedic surgeons but also serves as a valuable resource for young Turks venturing into hip surgeries. MATERIAL AND METHODS: 14 patients with femoral neck fractures underwent surgery using the modified McFarland and Osborne approach and were followed up for a period of six months. The functional outcome was analyzed by the Modified Mobility and Aids Scoring Matrix. RESULTS: Seven of the 14 patients attained pre-injury status with respect to the Mobility and Aids scoring matrix. six patients had a fall of 1, and one patient had a fall of 2, as compared to pre-injury status. CONCLUSION: Our research suggests that this method serves as a superior alternative to conventional approaches, demonstrating notable advantages in terms of dissection difficulty, reduced risk to neurovascular structures, and minimized post-operative hip dislocations. Additionally, it exhibits a favorable outcome, enabling a return to pre-injury levels of activity.

Candida parapsilosis in Late Prosthetic Joint Infections Among Immunocompetent Patients: A Case Series.

Introduction: Fungal prosthetic joint infections (PJIs) are very rare in immunocompetent patients. PJI can present either early, delayed, or as late chronic infections. Diagnosis of fungal PJI presenting late is challenging due to the difficulty in isolation as well as the clinical presentation very similar to an aseptic loosening. There are no clear guidelines regarding the management of these patients. Case Report: We present five cases of Candida parapsilosis PJI presenting as late chronic infections. All five patients were culture-negative preoperatively, immunocompetent, and with good soft-tissue condition. There were three infected knee prostheses and two infected hip hemiarthroplasty. All of them were treated with extensive debridement, meticulous sampling, and extended culture. We treated all of them with long-term antifungals without any disease reactivation or recurrence till the last follow-up. Conclusion: Fungal infection should be suspected in immunocompetent patients presenting early with features of aseptic loosening but without typical signs of periprosthetic infection. Revision with long-term suppressive therapy can give good results in these patients.

A Rare Case of Periprosthetic Fracture with Fracture of Femoral Stem around a Bipolar Hemiarthroplasty.

Introduction: The incidence of periprosthetic fractures (PPF) around a total hip arthroplasty continues to increase with the rise in number of arthroplasties performed. However, fracture of the femoral stem has become very rare since the development of modern prosthetic designs. We present a rare case of an 80-year-old man who sustained a periprosthetic femur fracture with a fracture of the femoral stem component around a bipolar hemiarthroplasty. Case Report: This man sustained a Vancouver type B1 periprosthetic femur fracture with a fracture of the femoral stem component around a fully cemented bipolar hemiarthroplasty done 10 years back. This patient was treated with removal of the broken femoral stem and osteosynthesis with a plate and cerclage wire plus revision to a longer stem prosthesis. Conclusion: PPF with a fracture of the femoral stem around a hemiarthroplasty is a rare and uncommon occurrence. A combination of osteosynthesis with revision arthroplasty with a longer stem proved to be a suitable treatment with satisfactory results. However, regular follow-ups post-arthroplasties are advocated to identify complications at an earlier stage.

Hemodynamic Effects of Bone Cement Implantation in Hip Arthroplasty: Insights from a Prospective Study in Eastern India.

Introduction: Bone cementation has various effects on hemodynamics including potentially fatal bone cement implantation syndrome (BCIS). Most of the studies on BCIS are from developed countries. We have studied the effect of bone cement on hemodynamics in hip arthroplasty in the eastern Indian population and compared it with the available literature. Materials and Methods: This prospective study was done by a team of orthopedic surgeons and anesthesiologists in a tertiary center in eastern India between March 2020 and December 2022. Result: Seventy-two patients (Male 38: and Female 34) of age between 25 and 100 years fulfilling the inclusion criteria were included. In 43 patients (43/72, 59.72%) systolic and diastolic blood pressure fell in the range of 10 mmHg, in 22 patients (22/72, 30.56%) fall in blood pressure was in the range of 10-20 mmHg, and more than 20 mmHg fall in blood pressure were seen in seven patients (7/72, 9.72%). SPO2 decreased from 97-100% to 94-96% in 28 patients and 90-93% in six patients, which began to rise after 5 min of cementing and returned to normal after 10 min. Arrhythmias were seen in 16 patients with multiple comorbidity. Two patients had a cardiac arrest and one patient died after 6 h in the intensive care unit. Conclusion: Pre-operative evaluation, perioperative monitoring of hemodynamic parameters during cementing especially in high-risk patients with multiple comorbidities, and taking essential precautions during cemented arthroplasty are the key to preventing complications like BCIS.

No Differences in Major In-Hospital Outcome Metrics When Comparing the Direct Lateral Approach to the Posterior Approach for Hemiarthroplasties After Traumatic Displaced Femoral Neck Fractures.

Introduction: The surgical approach of hemiarthroplasty for displaced femoral neck fractures remains debated. The study objective was to compare in-hospital outcomes for geriatric displaced femoral neck fractures treated with hemiarthroplasty based on surgical approach (direct lateral vs. posterior approach). Materials and Methods: This retrospective cohort study included geriatric patients (≥60 y/o) admitted 7/1/2016-3/31/2020 treated with hemiarthroplasty. Outcomes included: operative time (incision to closure), length of stay (HLOS), and blood loss volume (mL). The Harding direct lateral approach was compared to the posterior approach; P < .05. Results: There were 164 patients (59% direct lateral, 41% posterior). Patients treated with the direct lateral approach had an advanced directive (P = .03), dementia, (P = .03), or were functionally dependent (P = .03) more often than patients treated with the posterior approach. Time to surgery was comparable between groups (P = .52). The direct lateral approach was associated with a shorter operative time (2.3 vs. 2.8 h, P = .03), a longer HLOS (5.0 vs. 4.0 days, P < .01), and a lower median volume of blood loss (50 vs. 100 mL, P = .01), than the posterior approach, respectively. In a stratified analysis, for those who were not functionally dependent, did not have dementia or an advanced directive, the direct lateral approach led to a longer HLOS (P = .03) and shorter operative time (P = .04) than the posterior approach. Whereas among those who were functionally dependent, had dementia or had an advanced directive, the direct lateral approach led to less blood loss (P = .02) than the posterior approach. Discussion: While those treated with the direct lateral approach lost significantly less blood, they had a significantly longer HLOS than those treated with the posterior approach. Comorbidities significantly modified outcomes, which may suggest their presence could assist with treatment decisions. Conclusions: This study found neither approach, the direct lateral nor posterior, to be superior. Surgical approach could remain physician preference.

Outcomes of Corrective, Concentric (C2) Glenoid Reaming combined with Pyrocarbon Hemiarthroplasty for B2, B3 Glenoid Arthritis.

BACKGROUND: Posterior humeral subluxation (PHS) in B2/B3 glenoid is a cause of asymmetric long-term stress on the glenoid and the potential reason for glenoid loosening in anatomic total shoulder arthroplasty (ATSA) and painful glenoid erosion in hemiarthroplasty with metallic heads (HA-Metal). We hypothesized that corrective and concentric reaming (CCR) of the glenoid associated with pyrocarbon hemiarthroplasty (HA-PYC) could improve the centering of the humeral head and decrease the risk of persistent painful glenoid erosion in young/active patients with B2/B3 glenoid. METHODS: Between 2014 and 2020, 41shoulders (in 35 patients, mean age of 57.9 years) underwent HA-PYC combined with CCR reaming for B2 (n=30) or B3 (n=11) osteoarthritis. Patients were prospectively followed with computed tomography (CT) scans performed preoperatively, immediate postoperatively and at last follow-up (> 2 years). The primary outcomes were 3D-corrected CT-scan measurements of glenoid version, PHS, progression of glenoid erosion. Secondary outcomes included functional outcome scores, return to activities, and revision rate and complications. RESULTS: At a mean follow-up of 4.5 years (2 to 9.5 years), the prosthesis survival was 95% (39/41). No patient has been reoperated for painful glenoid erosion. The mean glenoid retroversion decreased from 17.1° ± 7.5 preoperatively to 8.3° ± 8.2 at last follow-up (p=0.001), and the mean PHS from 74% to 56.5% (p=0.001) based on the scapular plane and from 59.9% to 50.3% based on the glenoid plane. The humeral head was recentered in 97% according to the glenoid surface and 71% according to the scapular plane. Correction of PHS in the scapular plane was highly correlated to correction of glenoid retroversion (p<0.001). CT-scan measurements showed that the average total medialization was 3.7 ± 3.2 mm (2.0 ± 1.8 mm due to reaming and only 1.7 ± 2.4 mm due to erosion). The Adjusted Constant score increased from 43% ± 13 to 97% ± 16 and the Subjective Shoulder Value from 38% ± 14 to 84 % ± 12 (p<0.001). Overall, 84% of active patients returned to work and all patients returned to sports. CONCLUSION: In B2/B3 glenoid arthritis, corrective, concentric glenoid reaming combined with HA-PYC improves centering of the humeral head and shows a low risk of painful glenoid erosion at mid-term follow-up. The combined procedure results in excellent functional outcomes and high prosthesis survivorship at mid-term follow-up. HA-PYC and CCR is offering an alternative shoulder arthroplasty for young/active patients with B2/B3 glenoid osteoarthritis who want to return to work or sports practice.

Patient Satisfaction Following Non-Operative Treatment of Geriatric Hip Fractures: A Case-Control Study.

Introduction: A minority of geriatric hip fracture patients pursue non-operative treatment. Compared with surgical patients, non-operative patients have higher mortality rates. However, patient satisfaction following non-operative vs operative treatment has not been investigated extensively. The purpose of this study was to compare satisfaction among non-operatively vs operatively treated hip fracture patients. Methods: We identified patients aged 60+ years with proximal femur fractures treated over a 10-year period. Excluded were patients with isolated greater/lesser trochanteric fractures. Patients or relatives were asked to complete a 6-question survey about their treatment satisfaction. Results: Survey responses from 56 operative and 28 non-operative patients were recorded. Overall, 91.1% of operative and 82.1% of non-operative patients were satisfied with their treatment course (P = 0.260). However, only 71.4% of non-operative patients were satisfied with treatment option explanations vs 83.9% of operative patients (P = 0.014). While only 64.3% of non-operative respondents were satisfied with the ultimate treatment outcome (vs 85.7% of operative patients, P = 0.025), 89.3% of patients in each cohort would choose the same treatment plan again. Discussion: Our findings highlight the complexity of defining patient satisfaction, particularly in a geriatric hip fracture population. Unlike previous studies, we chose a direct approach to quantifying patient satisfaction by asking participants specifically about satisfaction with treatment outcome and the overall treatment course. Additional survey questions were then included to assess factors considered important in treatment satisfaction, such as health care provider treatment explanations, post-treatment mobility, and palliative care service involvement. Conclusions: We identified significant differences between non-operatively and operatively treated geriatric hip fracture patients regarding satisfaction with the explanation of treatment options, and ultimate treatment outcomes. There was no significant difference in overall satisfaction with the treatment course or likelihood of choosing the same treatment again. Further research investigating patient satisfaction following geriatric hip fracture treatment is warranted.

Impact of Intraoperative Femoral Fractures During Cemented Hemiarthroplasty for Femoral Neck Fractures.

BACKGROUND: There have been several studies on intraoperative femoral fractures (IFFs) during primary total hip arthroplasty, but it is not well understood how this complication affects the patient population undergoing cemented hemiarthroplasty. This study aimed to analyze the impact of IFFs sustained during cemented hemiarthroplasty for the treatment of femoral neck fractures. METHODS: A retrospective review was conducted of all patients who were treated for Arbeitsgemeinschaft für Osteosynthesefragen/Orthopaedic Trauma Association (AO/OTA) 31B fractures with cemented hemiarthroplasty between January 1, 2000, and December 31, 2021, at a single academic Level 1 trauma center. An initial cohort was constructed of all patients who sustained an IFF during their surgery, yielding 31 patients after excluding those who sustained a pathologic fracture or had incomplete data. These patients were matched 1:2 on age, sex, and body mass index (BMI) to patients in a control cohort. The primary outcome measure was implant failure. Secondary outcome measures included complications, all-cause mortality, and radiographic outcomes (subsidence, femoral component loosening, acetabular wear, and heterotopic ossification) postoperatively. RESULTS: Subsequent implant revision was required in 3.2% (n = 1) of patients who sustained an IFF and 1.6% (n = 1) of patients who did not. After adjusting for comorbidities, there was no observed excess risk of implant failure in the fracture cohort when compared to the control cohort (hazard ratio [HR] = 0.30, P = 0.740). There was no observed excess risk of morbidity (HR = 0.69, P = 0.621) or all-cause mortality (HR = 0.23, P = 0.330). Radiographic outcomes also did not significantly differ between the two cohorts (P > 0.05). CONCLUSION: Intraoperative fractures during cemented hemiarthroplasty do not contribute to an increased risk of secondary surgery, morbidity, or mortality after surgery. They also do not adversely affect radiographic outcomes postoperatively.

The Copenhagen Classification System for Distal Humeral Fractures is useful to identify patients who may require treatment with hemi- or total elbow arthroplasty.

Background: Classification systems are only useful if there is agreement among observers. The purpose of this study is to introduce a simple and clinically applicable classification system - The Copenhagen Classification System for Distal Humeral Fractures (CCDHF) and to compare the interobserver and intraobserver agreement for this classification with the Arbeitsgemeinschaft für Osteosynthesefragen/Orthopedic Trauma Association (AO/OTA), and the Sheffield classification systems. The primary objective of the new classification system is to distinguish fractures that may not be suitable for open reduction and internal fixation, necessitating treatment options such as elbow hemiarthroplasty or total elbow arthroplasty (TEA). Methods: Five consultant elbow surgeons assessed a consecutive series of 105 sets X-rays of distal humeral fractures on 2 occasions with at least 10 weeks interval. All X-rays were classified according to AO/OTA, Sheffield, and the CCDHF systems. The CCDHF system has been developed collaboratively by a panel of five experienced elbow surgeons. Based on consensus, the surgeons identified specific fracture characteristics where elbow hemiarthroplasty or TEA might be needed. Results: The mean interobserver agreement was fair for AO/OTA and moderate for Sheffield and the CCDHF. The mean intraobserver agreement was moderate for AO/OTA and substantial for Sheffield and the CCDHF. The observers were uncertain about the classification in 29% of the cases with the AO/OTA classification, 15% with the Sheffield classification, and 12% with CCDHF. Conclusion: The CCDHF demonstrated validity and clinical applicability and can assist surgeons in identifying fractures that may require hemiarthroplasty or TEA treatment.

Role of Tranexamic Acid in Controlling Blood Loss in Hemiarthroplasty of the Hip: A Prospective and Observational Study.

INTRODUCTION: Tranexamic acid, an antifibrinolytic drug, is well-established for its efficacy in reducing intraoperative and postoperative blood loss in major orthopedic surgeries, particularly total knee replacement (TKR) and spine surgeries. However, there is limited research on the role of tranexamic acid in hemiarthroplasty of the hip. This study aims to investigate the efficacy of tranexamic acid in controlling blood loss in hemiarthroplasty of the hip. OBJECTIVES: The primary objective was to analyze the pre- and postoperative changes in hemoglobin levels among patients undergoing hemiarthroplasty of the hip with and without intravenous tranexamic acid administration. METHODS: A prospective observational study was conducted at the Department of Orthopedics of Government Medical College, Kannur, and St. Joseph's Hospital, Karuvanchal, Kannur. Patients undergoing hemiarthroplasty of the hip with 1 gm of intravenous tranexamic acid were compared with those without tranexamic acid. The sample size was calculated to be 33 in each group. Data were collected using a standardized proforma, entered into an Excel sheet (Redmond, USA), and analyzed using IBM Corp. Released 2017. IBM SPSS Statistics for Windows, Version 25.0. Armonk, NY: IBM Corp. RESULTS: The study comprised mainly elderly females with a mean age of 74.84 ± 8 years. There was a significant reduction in postoperative hemoglobin drop, requirement for postoperative blood transfusion, and total drain output for the initial three postoperative days among patients who received intravenous tranexamic acid. CONCLUSION: Preoperative administration of intravenous tranexamic acid significantly reduced postoperative hemoglobin drop and the need for postoperative blood transfusion in patients undergoing hemiarthroplasty of the hip. This highlights the efficacy and safety of tranexamic acid in controlling blood loss in this surgical setting.

[Elbow hemiarthroplasty for coronal shear fractures of the distal humerus]. / Ellenbogenhemiprothese bei koronaren Abscherfrakturen des distalen Humerus.

OBJECTIVE: The aim of the operation is to replace the articular surface of the distal humerus in cases of nonreconstructible fractures of the distal humerus. INDICATIONS: Active patients with high functional requirements, in whom weight limitation of total elbow arthroplasty should be avoided. CONTRAINDICATIONS: Contraindications include fractures with irreconstructible epicondyles and/or irreconstructible collateral ligaments, as well as ulnohumeral, or radiohumeral osteoarthritis. SURGICAL TECHNIQUE: Following subcutaneous anterior transposition of the ulnar nerve, surgical dislocation of the elbow joint is achieved through a paratricipital approach with release of the soft tissue structures from the humerus. After resection of the trochlea, the intramedullary canal of the humerus is prepared using rasps in order to implant the hemiprosthesis with retrograde cementing. Finally, the medial and lateral collateral ligaments as well as the flexors and extensors are repaired. POSTOPERATIVE MANAGEMENT: Early functional rehabilitation in a hinged elbow orthosis while avoiding varus/valgus stress after wound healing is completed. RESULTS: Between 2018 and 2022, 18 patients with coronal shear fractures were treated with elbow hemiarthroplasty. The mean Mayo Elbow Performance Score (MEPS) was 79 (70-95) after a mean follow-up of 12 months. The mean range of motion was 99° (70-130°) in extension-flexion and 162° (90-180°) in pronation-supination.

Postoperative outcomes of third-generation shoulder hemiarthroplasties for three-and four-part proximal humeral fractures: A systematic review of published studies from 2012 to 2022.

Background: The aim of this study was to provide up-to-date evidence on the outcomes for hemiarthroplasties (HAs) that were performed using modern third-generation prostheses (post-2004) for isolated (excluding head-splits and fracture-dislocations) three-and four-part proximal humerus fractures (PHFs). Methods: PubMed, Medline, Embase and the Cochrane register were searched from January 1, 2012, to November 15, 2022, conforming to the PRISMA guidelines. The outcome measures were the complication rates, revision rates, surgery-related postoperative mortality, post-operative clinical outcome scores and radiological outcomes. Results: 432 hemiarthroplasties in 432 patients were performed across the 11 eligible studies (two prospective and 9 retrospective). Three studies compared HA versus reverse shoulder replacement (RSR); one study compared HA with locking plate fixation (LPF) and RSR; one study compared HA with LPF. 61.1 % and 19.4 % of hemiarthroplasties were performed using cemented and uncemented techniques respectively, while cementing data was ill-defined in 19.4 % of shoulders. The results for the outcome measures have been derived directly from the included studies and no statistical pooling was performed, due to heterogeneity in the different study designs and outcomes. Descriptive data synthesis from the included studies showed that third generation HAs have higher overall postoperative complication rates, with similar revision and mortality rates when compared to RSR and LPF for three-and four-part PHFs. RSR and LPF showed better statistically significant improvements than HA for the Constant-Murley score, Quick DASH, forward flexion and abduction. Mixed results were observed for the DASH score, ASES score and internal rotation ROM between RSR/LPF versus HA. Conclusion: Low to moderate quality evidence from this review showed that even third-generation HA prostheses provided worse overall outcomes than RSR and LPF for three-and four-part PHFs.
