Functional outcomes of Total Hip Replacement using modified Harris Hip Score

Background: Total hip replacement (THR) is a common surgery for relieving pain and improving the quality of life in patients with moderate to severe hip arthritis. The primary reason for THR is severe hip osteoarthritis, when conservative measures fail to relieve pain. The objective of the study was to examine functional outcomes, indications, and complications of THR using mHHS at different stages. Methods: A prospective observational study was carried out at the Department of Orthopedics, National Trauma Center, NAMS, from September 2019 to December 2020. The study included first 35 hips of 35 patients who underwent Total Hip Replacement at our hospital and met the inclusion criteria. Follow-up assessments were conducted at 6 weeks, 3 months, and 6 months after the surgery. Each visit involved thorough clinical and radiological examinations, as well as documentation of the mHHS chart. All continuous variables were expressed as mean ± standard deviation and two sample t test was used to compare means of two sub groups. Results: The study enrolled participants aged 26 to 66, with 60% male and 40% female. Right sided involvement was observed in 55% of cases, while the left side was affected in 45%. The most common reason for surgery was osteoarthritis caused by avascular necrosis of the femoral head. The average preoperative mHHS was 28, which increased to 64 at six weeks, 86 at three months, and 92 at six months. The study found that 80% of participants achieved excellent results. Complications, including a 2.85% dislocation rate, were reported. Conclusion: THR is a safe and effective procedure, providing excellent functional outcomes and minimal complications when performed carefully and precisely. Long-term studies are needed to investigate late complications and further establish the efficacy of the implants and the procedure

Outcome of intertrochanteric fracture managed with proximal femoral nail antirotation 2

Background: Intertrochanteric fracture is a common condition seen in elderly population which is managed with operative procedure in the department of orthopedics. The proximal femoral nail antirotation (PFNA) system was developed by the AO/ASIF in 2004 for this fracture that provides optimal anchoring and stability when the implant is inserted into the osteoporotic bone. The main characteristic of the implant is the use of a single blade with a large surface area and insertion of the blade compacts the cancellous bone. Aims and Objectives: The aim of the study was to study the functional outcome of intertrochanteric fracture managed with PFNA2. Materials and Methods: The prospective and observational study was conducted in patients diagnosed with intertrochanteric fracture admitted in orthopedic ward, Western Regional Hospital, Pokhara. Pre- and post-operative fracture alignment, Harris hip score (HHS), post-operative complications were taken into account. Results: Out of 55 cases taken into study, 36 (65.45%) were male and 19 (34.55%) were female. Maximum number of patients allocated in our study falls in 71–80 years group (29%) with least number in age group of 90 years or more (1.9%). Right-sided intertrochanteric fracture were 27 (49%) and left side involved were 28 (51%). Twenty-eight (51%) falls in Type II and 27 (49%) falls in Type III Boyd and Griffin intertrochanteric fractures. There was a marked improvement in fracture alignment after the operation with various parameters taken into consideration. Pre-operative HHS was 5.52±5.38 (Poor) and immediately after the procedure, it was 30.41±3.04 (Poor), 89.86±3.59 (Good) at 6 months, and 95.56±1.257 (Excellent) at 12 months. One case had blade cut out at immediate post-operative period, eight cases had surgical site infection, and five cases had GT fracture. Conclusion: This study showed that PFNA2 is an effective operative procedure in management of intertrochanteric fractures by achieving better fixation through bone impaction especially in osteoporotic bone.</jats:p
