目的探讨带旋髂深血管蒂骨膜瓣植入治疗未成年股骨颈骨折术后股骨头缺血性坏死（avascular necrosis of femoral head，ANFH）的疗效。 方法2006年12月－2011年8月，采用带旋髂深血管蒂骨膜瓣植入术治疗9例（9髋）未成年股骨颈骨折术后ANFH。其中男6例，女3例；年龄10～18岁，平均14.7岁。骨折原因：交通事故伤5例，高处坠落伤3例，摔伤1例。骨折后3～16 d行克氏针或空心螺钉内固定术，术后10个月内股骨颈骨折均愈合。术后10～42个月，平均24.4个月发生ANFH。骨坏死影像学评估按照Steinberg分期标准：Ⅲb期1例，Ⅲc期2例，Ⅳa期1例，Ⅳb期3例，Ⅳc期2例。根据手术前后髋关节功能Harris评分变化和Steinberg分期改变进行临床评价和影像学评估。 结果术后患者切口均Ⅰ期愈合，无感染、下肢深静脉血栓形成、供区麻木、疼痛及其他手术相关并发症发生。9例均获随访，随访时间38～76个月，平均52个月。患者患髋或膝内上疼痛缓解，肢体无明显短缩，行走步态改善，患髋关节活动度增加。末次随访时，髋关节功能Harris评分为（92.7±9.9）分，与术前（62.8±3.6）分比较差异有统计学意义（t=—12.244，P=0.000）；获优5例、良3例、差1例；治疗成功率为88.89%（8/9）。末次随访时，除1例术前Ⅲb期进展至Ⅳb期外，其余患者分期改善或稳定，影像学成功率为88.89%（8/9）。 结论带旋髂深血管蒂骨膜瓣植入治疗未成年股骨颈骨折术后ANFH，能为股骨头提供良好的成骨及血管重建
