Background and Aim: Hemiarthroplasty (HA) and total hip arthroplasty (THA) are the two alternate surgical interventions required for displaced femoral neck fractures in elderly patients. Though THA is superior in certain aspects such as hip pain, reoperation rate and function but had higher dislocation rate compared to HA. The present study aimed to compare the hemiarthroplasty and total hip arthroplasty in elderly patients with displaced femoral neck fractures. Patients and Methodology: This retrospective cohort study was conducted on 20 displaced femoral neck fractures patients in the Department of Orthopedic QAMC/ BVH Bahawalpur from January 2021 to August 2022. Prior to start of study, ethical approval was taken from the institute research and ethical committee. Written informed consent was obtained from each individual. Patients aged >60 years and had femoral neck fractures were enrolled. Rheumatoid arthritis in fracture hip patients, non-ambulatory patients, and pathological fracture patients were excluded. Patients were categorized into two groups; group-I patients undergoing hemiarthroplasty and group-II patients undergoing total hip arthroplasty. Post-operative complications such as fracture, medical issues, dislocation, surgical site infection, and mortality (1 year) were assessed in both groups. Harris Hip Score (HHS) was used for the assessment of function outcome at one month, three months, six months, and twelve months. SPSS version 25 was used for data analysis. Results: Of the total 20 femoral neck fractures patients, 10 patients underwent hemiarthroplasty and 10 underwent total hip arthroplasty. The overall mean age was 69.44±7.91 years. Demographic details or baseline features were almost similar in both groups. During follow-ups, patients who underwent total hip arthroplasty (group-II) had higher Harris hip score than group-I patients. The mean HHS score in group-I patients were 61.53, 68.24, 70.81, and 76.16 at follow-up visit after one month, three months, six months, and twelve months respectively while In group-II, the mean HHS score were 66.23, 69.82, 73.25, and 78.92 respectively. Conclusion: Our study concluded that total hip arthroplasty in elder patients with femoral neck fractures provided better hip functional outcome and lower morbidity and mortality as compared to hemiarthroplasty group. THA could be considered as priority based treatment modality for femoral neck fractures patients than HA due to higher Harris hip scores and lesser complications.

Objective: The aim of this study is to compare the effectiveness of retrograde femoral interlocking nail versus dynamic condylar screw in distal femoral shaft fractures. Study Design: Prospective/Randomized comprehensive Place and Duration: Department of Orthopaedic Surgery Bahawal Victoria Hospital (BVH) / QAMC, Bahawalpur for duration of eight months i.e July 2020 to February 2021. Methods: Total 65 patients of both genders were presented in this study with age ranges between 20-40 years. Patients detailed demographics age, sex and BMI were calculated after taking informed written consent. Patients were divided into 2- groups, I and II Group I had 32 patients and underwent for retrograde femoral interlocking nail and group II had 33 patients and received dynamic condylar screw. Mean operative time, mean union time of bones and complications were calculated. Effectiveness among both groups was calculated by HSS score. Complete data was analyzed by SPSS 22.0 version. Results: Most of the patients were males 40 (61.54%) and 25 (38.46%) were females. Mean age of the patients in group I was 26.46±4.28 years and in group II mean age was 30.78±8.22 years. Mean operative time in group I was 82.8±7.14 minutes while in group II it was 90.6±8.19 minutes. Mean union time in group I was 22.7±2.5 weeks and in group II was 26.21±5.3 weeks. According to HSS score in group I 16 (50%) results were excellent, 11 (34.38%) was good, 3 (9.8%) showed moderate and 2 (6.25%) was poor, while in group II excellent results were 15 (45.45%), 10 (30.30%) was good, 5 (15.15%) showed moderate and 3 (9.09%) showed poor results. Complications were observed joint stiffness, delayed union, non union and varus deformity were significantly lower in group I as compared to group II. Conclusion: We concluded in this comparison of study that bothretrograde femoral interlocking nail and dynamic condylar screw was useful and effective methods for trauma in distal femoral shaft fractures. But less union time and good outcomes were observed in interlocking nail as compared to dynamic condylar screw. Keywords: Distal femoral shaft fractures, Trauma, Dynamic condylar, Interlocking nail
