ABSTRACT
PURPOSE: The purpose of this study is to evaluate the results of bipolar hemiarthroplasty using calcar replacement stem for comminuted intertrochanteric fracture in elderly patients. MATERIALS AND METHODS: Between March 1998 and March 2008, the clinical records of 79 cases who were older than 75 years of age and underwent bipolar hemiarthroplaty, using calcar replacement stem with figure of eight and cerclage wiring, were reviewed. Their mean age was 82.4 years(75-92 years) and the mean follow-up period was 68 months(24-92 months). RESULTS: The mean postoperative Harris hip score was 82.1(62-92), and preoperative walking ability was recovered in 56 cases(71%). Bony ingrowth fixation was achieved in 70 cases(89%), and fibrous stable fixation was in 9 cases(11%). Stress shields were revealed in 21 cases(27%). Nonunion of trochanter was found in 3 cases(4%), and wire fixation breakages were in 3 cases after bony union. The mean duration of bony union was 16.3 weeks(12-38 weeks). Aseptic loosening was observed in 1 case and protrusio acetabuli were in 2 cases. CONCLUSION: The result of clinical and radiological evaluations of bipolar hemiarthroplasty, using calcar replacement stem with figure of eight and cerclage wiring, were satisfactory in elderly patients with comminuted intertrochanteric fracture.

PURPOSE: To evaluate the results of the treatment of femoral basicervical fractures aged 75 years or older. MATERIALS AND METHODS: We reviewed the clinical records of 60 patients who were older than 75 years and who underwent bipolar hemiarthroplasty for femoral basicervical fractures using calcar replacement stem between March 1999 and November 2005. The minimum follow up period was 2 years. We analyzed the results by conducting radiological and clinical evaluations such as assessing the patient's walking ability and modified Harris hip score, the activities of daily living, the associated medical conditions and arthritis, and postoperative disgnosis. RESULTS: The mean Harris hip score were 87.2 (74~92). Walking ability was recovered in 91% (55 cases) and activity of daily living was achived in 91% (55 cases). Press-fit fixations were 56 cases and bony ingrowth fixations were 57 cases. Stress shields were 28% (17 cases). Thigh pains were 5% (3 cases) and revision rate was 3% (2/60 cases). CONCLUSION: We consider bipolar hemiarthroplasty using calcar replacement stem in femoral basicervical fractures in the Elderly with severe osteoporosis is the useful treatment in view of the stable and rigid fixation of femoral stem, early ambulation, and the low rate of complications and death, even if the operation is technically very difficult.

PURPOSE: To evaluate the results of bipolar hemiarthroplasty using calcar replacement stem for hip fractures in elderly patients. MATERIALS AND METHODS: Between March 1995 and March 2005, the clinical records on 68 cases more than 75 years old who underwent the bipolar hemiarthroplasty using calcar replacement stem and followed minimum 2 years were reviewed. We evaluated the results by modified Harris hip score, walking ability, activity of daily living, complications, osteoporosis and radiologic findings. RESULTS: The mean postoperative modified Harris hip score was 88.3 (69~95) in femoral neck fractures and 83.5 (63~91) in femoral intertrochanteric fractures. Walking ability was recovered in 82.3% (56 cases) and activity of daily living was achived in 82.3% (56 cases). Complications were thigh pain, infection, femoral stem subsidence, stress shield, dislocation. CONCLUSION: We consider bipolar hemiarthroplasty using calcar replacement stem for unstable hip fractures in elderly patients with severe osteoporosis is the useful treatment in view of the stable and rigid fixation, early ambulation and the low rate of complications, even if the operation is technically very difficult.
