温哥华B型股骨假体周围骨折的治疗

目的:总结温哥华B型股骨假体周围骨折治疗的经验和体会。方法:自2004年2月～2009年8月收治人工髋关节置换术温哥华B型股骨假体周围骨折病人12例,均行手术治疗,包括:单纯钢丝环扎固定2例,普通接骨板固定1例,锁定加压接骨板固定4例,钢板结合钛缆固定1例,形状记忆合金环抱器内固定1例,生物型加长柄股骨假体置换2例,骨水泥型加长柄假体置换1例,术中植骨4例,术后结合石膏外固定1例。结果:术后随访4个月～18个月,平均15个月。11例病人骨折获得骨性愈合,1例股骨假体翻修术中出现骨水泥外溢,随访未出现假体松动临床症状。Harris评分单纯行骨折固定未行股骨假体翻修的病人Harris评分无明显影响,同时行翻修的病人Harris评分明显升高。结论:髋关节置换术中、术后股骨假体周围骨折以VancouverB型骨折多见,术前应根据此型骨折特点全面计划、准备,选择适合的内固定,术中仔细操作,可获满意疗效。
