目的：探讨多孔生物陶瓷棒置入术治疗早期股骨头坏死的近期临床疗效。方法2011年10月至2013年6月对13例（14髋）早期股骨头缺血性坏死患者应用多孔生物陶瓷棒置入术治疗。按Steinberg分期标准：Ⅰ期5例6髋，Ⅱa期5例，Ⅱb期3例。采用Harris髋关节评分系统评估置入前后髋关节功能改善情况。根据Steinberg分期系统进行影像学评价。结果13例患者均进行随访，随访时间6～22个月，平均16.8个月。Harris评分由术前（69.23±7.90）分提高到术后（85.30±9.80）分，优良率92.9%，治疗前后比较差异有统计学意义（P＜0.05）。随访摄片髋关节影像学表现稳定，近期股骨头无明显坏死进展。结论采用生物陶瓷棒置入术治疗早期股骨头坏死，手术操作简便，手术时间短，可阻止影像学进展，缓解症状，近期疗效满意。

Objective To explore the curative effect of treatment in early-stage avascular necrosis with porous bioceramics rod. Methods There were 13 patients of early-stage ANFH (14 hips) who were treated with porous bioceramics rod from October 2011 to June 2013. According to the Steinberg assessment, the study included 5 patients in Ⅰ term, 5 patients in Ⅱa term and 3 patients in Ⅱb term. The curative effects were evaluated according to Harris scoring system as well as the radiography grading system of Steinberg. Results All the 13 patients were followed up for 6-22 months, average 16.8 months. Harris scoring was up to 85.30±9.80 from 69.23±7.90 after operation, excellent rate reached to 92.9%. There existed a significant difference between the two group (P<0.05). Conclusion Treating early-stage ANFH with porous bioceramics rod is easy to operate and the operation time is short. It can prevent the radiographic progression, alleviate the symptom, achieve curative effect satisfaction.
