Introduction: An intertrochanteric femur fracture is one of the most important health problems amongst the elder population. Aim: To evaluate the functional outcome and complications of cemented bipolar arthroplasty in unstable intertrochanteric femur fracture in Indian elderly patients. Methods: This study was conducted in the Department of Orthopedics, SMS medical college, and associated groups of hospitals, Jaipur between July 2017 to Dec 2019. 30 cases of unstable [four-part] Trochanter fracture have been included in this study. Results: The average age of the study patient was 75 years with the involvement of the left side in 55%. There was no case with the poor radiological result. There were two cases reported with limb lengthening less than 2 cm, and two patients with limb shortening one with < 2cm and one with > 2cm but these patients had good harris hip scores. At the final 1-year follow-up harris hip scoring system, 36-36% of patients had an excellent result, 46.66% had a good result, 10% of patients have fair results and 6.66% have a poor result. The patients who showed poor scores suffered from multiple medical problems and poor preoperative general physical health.
