Primary cementless bipolar long stem hemiarthroplasty for unstable osteoporotic intertrochanteric fracture in the elderly patients

Abstract

Background: Intertrochanteric fracture (ITF) is a major part of fracture in femur. 95% of ITF are found in elderly patients. Osteosynthese is the preferred method of choice. However, elderly patients had osteoporotic, combined with many of chronic disease conditions that increase the rate of osteosynthese failure. Hemiarthroplasty bipolar long-stem is a surgical method that helps patients relieve pain, facilitate early rehabilitation, limit long-term complications, and improve quality of life for patients. Aim: The aim of our study is to evaluate the clinical of the result of primary cementless bipolar long stem hemiarthroplasty in treatment for unstable ITF in the elderly patients. Methods: We retrospectively analyzed 35 cases of primary hemiarthroplasty performed for osteoporotic unstable intertrochanteric fractures (AO/OTA type 31-A2.2 and 31-A2.3 and Evans type III or IV fractures). There were 26 females and 9 males with a mean age of 77.1 years (range, 62-89 years). Results: Mean age of studied subjects was 84.29 ± 6.17, the lowest was 71, the highest was 96; ratio of male/female was 1:288. Follow-up of 33 patients for at least 6 months showed 88.6% caused by a low-energy injury; Average rehabilitation time was 4.63 ± 1.7 days. The average Harris point at the end was 90.4 ± 4.72. Conclusion: Primary cementless bipolar long stem hemiarthroplasty is one of good choices in treatment of unstable ITF in elderly patients with severe osteoporosis, helped patients improve the quality of life.
