    背景：多孔钽金属棒的研制与临床应用，为行保留股骨头手术提供了新的思路和方法。目前对于该术式的早期疗效比较肯定，尚缺乏中远期的随访。

    目的：探讨应用钽棒治疗早期股骨头坏死的中远期临床疗效。

    方法：2008年5月至2011年5月运用钽棒治疗早期股骨头坏死患者65例80髋，评估手术前、术后3个月及末次随访的Harris 评分，末次随访的股骨头生存率。

    结果 ：全部获 得随访，随访时间为 36～60 个月，平均 48 个月。股骨 头生存率可达 90%，其中 SteinbergⅠ期生存率 100%，Ⅱ期生存率95%，ⅢA期生存率73%。8例术后6～8个月出现股骨头塌陷，其余各髋未见进一步塌陷，末次随访X线片示假体位置良好。

    结论：钽棒植入术是治疗早期股骨头坏死的有效手段，其中远期疗效满意。

    股骨头坏死；钽棒；中远期疗效

    Background:Great development and clinical application of tantalum provides a new train of thought and method for reserved operations of femoral head.Early certain curative effects have been reported,but the surgical procedure still lacks of long-term follow-up.

    Objective:To explore the long-term curative effect of tantalum rod for the treatment of early avascular necrosis of femoral head.

    Methods:From May 2008 to May 2011,65 patients(80 hips)with early femoral head necrosis were treated by tantalum rod implantation.Harris score was recorded before operation,3 months after operation and at the last follow-up.The survival rate of femoral head was evaluated 36-60 months after surgery. ......
