PRIMARY MODULAR BIPOLAR HEMIARTHROPLASTY FOR UNSTABLE OSTEOPOROTIC INTERTROCHANTERIC FRACTURES IN ELDERLY

BACKGROUND: The optimal treatment for unstable intertrochanteric fractures in elderly patients is challenging because of difficult anatomical reduction, poor bone quality and delayed weight bearing. Internal fixation in these cases usually involves prolonged bed rest or limited ambulation to prevent implant failure secondary to osteoporosis that may develop complications like deep vein thrombosis, pulmonary embolism, pneumonia and bed sores. MATERIAL & METHOD: In 20 patients > aged 75 years with diagnosis of unstable intertrochanteric fractures (Evans III/IV), primary modular bipolar hemiarthroplasty was done and follow up was done for 2 years. RESULTS: The average age of the study subjects was 82 years (range 75-90 years). There were 12 males and 8 females. 12 patients (63.2%) were graded excellent, 6(31.6%) as good and 1(5.3%) as poor according to Harris hip score. There were no dislocation, loosening or late infection. CONCLUSION: Modular Bipolar hemiarthroplasty for unstable osteoporotic intertrochanteric fractures in elderly results in early weight bearing and improved quality of life.
