Background: Elderly patients typically suffer from intertrochanteric femoral fractures1, which are the most frequently operated-on fractures and have the greatest rates of morbidity and mortality2. Because of urbanization's increased sedentary lifestyle and longer life expectancy, these fractures are occurring more frequently. Aim: To evaluate the efficacy of PROXIMAL FEMORAL NAIL in the surgical management of unstable Intertrochanteric fractures of hip. Material & Methods: Study Design: A prospective hospital based observational study. Study area: Department of Orthopaedics, KLES JGMMC Medical College, Hubli, Karnataka. Study Period: March 2022 – Feb. 2023. Study population: Patients admitted with intertrochanteric fracture in department of Orthopaedics who underwent surgical treatment with proximal femoral nail. Sample size: study consisted of 25 subjects. Sampling method: Purposive sampling technique. Study tools and Data collection procedure: After the patient with intertrochanteric fracture was admitted to our hospital, all the necessary clinical details were recorded in the proforma prepared for this study. After the completion of the hospital treatment patients were discharged and called for follow-up to outpatient department at regular intervals (6weeks,12weeks, 6months,12months) for clinical and radiological evaluation. The patients were followed up till fracture union & yearly once from then-on. Results: Most of the patients were able to do partial weight bearing by 1-3 weeks and by the end of 3 months total 21 patients could do partial weight bearing and 1 patient didn‟t follow the postop protocol and did full weight bearing immediately after surgery. Out of total 25 cases 2 cases expired and 1 case lost follow-up. Breakage of nail was seen in a case of subtrochanteric fracture where there is nonunion of the fracture for which we have done revision nailing. Conclusion: From our study it can be concluded that Intramedullary implants for internal fixation of the proximal femur withstand higher static and a several-fold higher cyclical loading than DHS types of implants.
