股骨头无菌性坏死中高保留骨量技术应用在初次人工全髋关节置换的临床疗效

目的：探讨高保留骨量技术在股骨头无菌性坏死的初次人工全髋关节置换术的临床疗效。方法2006年6月-2012年12月治疗的股骨头无菌性坏死患者全髋关节置换手术64例，根据治疗方法分为两组，观察组（高保留骨量的初次全髋关节置换术）32例，对照组（常规的初次全髋关节置换术）32例，均经6～36个月的随访，平均随访18.7个月，统计术后髋关节早期及末次随访时Harris评分及VAS评分，复查X线片观察股骨柄及髋臼松动情况并采用SPSS 15.0进行统计。结果两组在早期的Harris评分及VAS评分无明显差别，而在随访末期的评分中差异有统计学意义。结论高保留骨量技术在股骨头无菌性坏死的初次全髋关节置换中有明确的效果，临床疗效满意，其高保留骨量将逐渐成为今后关节置换的趋势。

To research the clinical efficacy impaction autogenous bone graft in the primary bio-total hip arthroplasty in the aseptic necrosis of head of femur

Objective To discuss the clinical efficacy of impaction autogenous bone graft in the primary bio -total hip arthro-plasty in aseptic necrosis of head of femur .Methods There were 64 cases aseptic necrosis of head of femur used total hip arthroplasty operation in our hospital during June 2006 to December 2012.Two groups are divided according to treatment methods ,the observation group （impaction autogenous bone graft in primary total hip arthroplasty ） 32 cases,and control group （simply primary total hip arthro-plasty） 32 cases,respectively.All cases were follow-up from 6 months to 36 months （an average of 18.7 months）.The hip Harris score and VAS score was analysed during the early and last follow-up,observing the femoral and acetabular loosening in the X-ray,and ana-lysed by SPSS 15.0.Results The observation group and the control group showed no significant difference in the early Harris score and VAS score ,there were statistically significant in the follow-up stage in the score .Conclusion Impaction autogenous bone graft in the aseptic necrosis of head of femur has a clear effect in primary total hip arthroplasty ,the clinical effect is satisfactory ,high retention bone will gradually become the future trend of joint replacement .
