多孔钽棒治疗早中期股骨头坏死的临床研究

摘要

Objective To compare the clinical effect of the core decompression with transplantation bone and with implantation of tantalum rod for the treatment of avascula necrosis of the femoral head (AVN) at early-mid stage. Methods Forty seven AVN patients have been analyzed from March 2008 to July 2010. The control group (n=27) were treated with surgery of core decompression with transplantation bone, and experimental group (n=20) accept the surgery of core decompression with implantation of tantalum rod. Then the clinical effect of the two groups were observed. Results All the patients were followed up 24 months. After the operation, experimental group in VAS score was obviously decreased 1.39±0.44 VS 7.10±1.13) and in Harris hip score was significantly increased (89.73±9.03 VS 65.22±5.13) compared with pre-operation. Conclusion Implantation of AVN porous tantalum rod can prevent the necrosis femoral head from progressing to collapse, The early clinical evaluation function is better than the core decompression with transplantation bone.%　　目的比较单纯髓心减压加打压植骨与髓心减压加多孔钽棒植入治疗早中期股骨头坏死的临床疗效.方法2009年3月~2010年7月收治早中期股骨头坏死患者47例,其中,对照组27例,采用单纯髓心减压加打压植骨治疗.试验组20例,采用髓心减压加多孔钽棒移植治疗.比较两组治疗效果.结果术后随访24个月,试验组患者术后VAS评分明显降低(1.39±0.44)分VS(7.10±1.13)分,Harris评分明显升高(89.73±9.03)分VS (65.22±5.13)分.且在术后6、12、24个月时试验组的VAS及Harris评分均优于对照组(P<0.05).结论多孔钽棒植入治疗早期股骨头坏死可以有效防治坏死股骨头的进一步塌陷,早期临床功能评价优于单纯髓心减压加打压植骨治疗.
