摘要
[目的]探讨无柄人工髋关节置换术的治疗效果。[方法]取患髋后外侧切口显露髋关节,使股骨头脱位,清除关节内病变组织,用中心定位器定位打入中心针,用塑骨器塑骨,安装罩体,用中心钉和大、小粗隆松质骨螺钉固定。以有柄人工髋关节置换术同样方法安装髋臼假体。[结果]本组9例,平均随访时间1 a 8个月。按Harris关节功能评价标准评估,优5例,良2例,可1例,差无,优良率为7/9。[结论]无柄人工髋关节置换术,由于保留了全部的股骨颈和部分股骨头,力学传导与分布更接近于人体的自然生物力学状态,近期疗效满意,远期疗效仍有待进一步观察。
[Objective]To explore the clinical effect of the new stem- less total hip arthroplasty. [Method]Exposed the hip joint through posterior - exterior incision, dislocate the femoral head, clear away sick tissues inside joint, throw into the centric pin by guide of the centric localizer, repaired bone by machine of modeling bone, set the cup and fixed by centric screw and the screw of substantia spongiosa bone on trochanter major and trochanter minor of the femoral. The acetabulum prosthesis according to the traditional total hip arthroplasty were fixed. [Result]Nine cases were followed up for average 20 months, evaluated by Harris Score standard, excellent 5 cases, good 2 cases, fair 1 cases, poor 0 case, the rates of excellent and good is 88.89%. [ Conclusion] Because of keeping entire neck and part head of the femur, biomechanics conduction and distribute of the stemless hip of prosthesis achieves natural biomechanics state of the human body, the treatment effect of short -term is satisfying, the treatment effect of long - term will go on get observation in future.
