Introduction: The management of comminuted inter trochanteric fractures of femur in elderly patients is tricky as there is challenge of difficult anatomical reduction in osteoporotic bones, need for prolonged immobilization after surgery and more chances of screw cut out in poor quality bone. Prolonged immobilization will leads into complications like bed sores, chest infections , deep vein thrombosis, dependency and psycho social side effects , increasing the both morbidity and mortality. The aim of our study was to evaluate the functional outcome of cemented bipolar hemiarthroplasty in comminuted inter trochanteric fractures of femur in elderly patients using Harris Hip Score. Materials and Methods: This is a Prospective study conducted from (March 2009 to June 2017) at Department of Orthopaedics, chalmeda Anand Rao Institute of Medical Sciences, Karimnagar Twenty elderly patients with age above sixty years having comminuted inter trochanteric fractures of femur treated by using cemented bipolar hemi arthroplasty were evaluated for functional outcome using Harris Hip Score. Results : There were 12 female and 8 male patients with mean age of 68.82 years(60 -82)years treated by cemented bipolar hemiarthroplaty. Patients were followed up at 6 weeks, 3months , 6 month and 1 year. At one year follow up with help of Harris Hip Score 8 patients(40%) were graded as excellent, 10 patients(50%) as good and 2 patients (10%) as fair. Conclusion: The procedure offered rapid mobilization , early return to pre injury level and gave a lasting solution to elderly patients with comminuted inter trochanteric fractures of femur.
