Abstract
Objective To investigate the zirconium niobium alloy femoral head in young and middle-aged feasibility and the recent curative effect of total hip replacement.Methods Since May 2008 ～ Jan 2014 22 cases (22 hip) youth with femoral head avascular necrosis were treated with zirconium niobium alloy in our hospital.The Harris hip score and WOMAC osteoarthritis index scale to evaluate the hip joint function.According to the X ray film Gruen partition around the femoral prosthesis and the acetabulum prosthesis around each Deiee bone for recording and analysis of partition,judge whetherthereisbone dissolve and prosthesis loosening.Results All patients were followedup for38.3±5.3 months (range 25 ～ 63).The Harris score improved from 41.5±9.5 (range,11 ～ 67) preoperatively to 93.8±5.7 (83-99) at the time of final follow-up.There were significant differences in Harris score (t＝23.478,P＜0.01).The WOMAC index improved from 75.3±6.8 (range,58 ～ 91) preoperatively to 9.5±5.7 (range,1 ～ 12) at the time of final follow-up.There were significant differences in WOMAC Index (t＝19.163,P＜0.01).Infection,deep vein thrombosis,thigh pain,prosthesis dislocation,prosthesis crushing,sound,dissolution of bone and prosthesis loosening did not appear during the follow-up period.Conclusion The zirconium niobium alloy femoral head in young and middle-aged total hip replacement,short-term curative effect is satisfactory,can reduce the loose prosthesis and the surrounding bone resorption,but high risk for dislocation and difficult resetting patients should be careful to application.关键词
