摘要 目的探讨可吸收螺钉辅助重建髋臼粉碎性骨折的软骨与骨性关节面解剖结构及对损伤软骨愈合、关节功能的影响。方法髋臼复杂粉碎性骨折88例(90髋),均为关节内粉碎性骨折。选择髂腹股沟、后外侧或前后联合入路。术中粉碎严重的关节面(碎裂软骨下骨及未游离的关节软骨)采用可吸收螺钉(聚左旋乳酸可吸收骨固定系统)先予以固定、阻挡、拼接,完成骨折块与主体骨一体化后再应用骨盆重建接骨板固定。术后根据固定情况给予穿矫形鞋或皮牵引限制髋部活动4~6周,床上行关节屈伸、收展功能锻炼。随访11~22个月评价疗效。结果 88例X线片示骨折全部愈合,关节面平整,无明显塌陷及骨性游离体形成。临床功能评价优86髋,良3髋,差1髋。结论利用可吸收螺钉完成复杂粉碎性髋臼骨折折块间固定,可明显提高重建接骨板在严重髋臼骨折的复位质量、骨软骨折块愈合率,使髋关节获得满意功能,降低并发症的发生率。
