Abstract:
BACKGROUND:Conventional dynamic hip screw or artificial joint replacement can be used to treat unstable intertrochanteric fracture in aged patients. It remains unclear whether we should select one-stage replacement or remedial joint replacement after failture, and there is no unified standard globaly. OBJECTIVE: To observe the outcomes and prognosis of one-stage artificial joint replacement for unstable intertrochanteric fracture in aged patients. METHODS:From April 2008 to October 2011, 21 patients with unstable intertrochanteric fracture in aged patients were repaired with one-stage artificial joint replacement at the Second Department of Orthopedics, Changji Prefecture People’s Hospital. Among 21 patients, 1 patient previously combined with avascular necrosis of the femoral head and traumatic arthritis received biological artificial total hip replacement. Three cases were subjected to standard bone cement bipolar artificial femoral head replacement. 17 cases underwent biological bipolar artificial femoral head prosthesis replacement. Al artificial joint, internal fixation material and accessory joint replacement surgical instruments were purchased outside China. Al patients were folowed up regularly. Hip joint function was assessed by Harris hip score. RESULTS AND CONCLUSION: Al operations were completed by the same group of physicians. Operation time was 30-60 minutes, averagely 42 minutes. Incision length was 8 to 15 cm, averagely 11 cm. Average intraoperative blood loss was 50-300 mL, averagely 150 mL. The number of transfusion cases was 13. 1.5 U blood was transfused averagely in each patient during hospital stay. One 76-year-old patient combined with hypertension, coronary heart disease and diabetes suffered from sudden death due to acute myocardial infarction at 9 days after replacement. B ultrasound revealed venous thrombosis of calf muscle of double lower extremities at 3 days after replacement. No complications such as prosthetic loosening, sinking, infections and thrombosis were detected. Except 1 case died, the other 20 cases received folow-up for 6-49 months. Harris hip score was 73±4 before discharge and 82±6 during last folow-up. These data confirm that effects of one-stage artificial joint replacement for unstable intertrochanteric fracture in aged patients are affirmative, but the number of case is stil less, and deserves further investigations. We suggest that in patients with conformed indication, one-stage artificial joint replacement can be the first choice.
