【摘要】:目的探讨采用肢体短缩延长术治疗胫骨感染性骨缺损及慢性骨髓炎的疗效。方法 2011年1月—2016年4月采用肢体短缩延长术治疗胫骨感染性骨缺损及慢性骨髓炎19例。男13例,女6例;年龄22~62岁,平均44岁。致伤原因:交通事故伤16例,压砸伤1例,高处坠落伤2例。18例为小腿开放性骨折(GustiloⅢB型)外固定支架固定后形成感染性骨缺损、骨髓炎,1例为闭合骨折内固定术后感染形成慢性骨髓炎。既往手术2~5次,平均3次。受伤至骨搬移术时间为3~11个月,平均6.5个月。清创后骨缺损长度为2.0~5.5 cm,平均4.3 cm。术中胫骨短缩后松开止血带检查肢体末梢血运,7例直接闭合创面,5例采用邻近皮瓣修复,5例采用腓肠神经营养血管皮瓣修复,1例采用腓肠肌内侧头肌皮瓣修复,1例单纯植皮修复。选用单臂外固定架或环式外固定架,并在胫骨近侧或远侧干骺端的两排外固定架钉之间完全锯断;1周后以1 mm/d速度进行肢体延长。结果术后19例患者均获随访,随访时间10~36个月,平均14个月。2例对合端创面延迟愈合,余均顺利愈合。18例对合骨端自然愈合,1例因病灶骨未完全切除致对合骨端发生骨不连。5例发生牵张骨痂生长缓慢,其中4例经"手风琴"技术和注射红骨髓后顺利愈合,1例植骨辅助内固定后对合骨端愈合。骨延长时间为1~3个月,延长指数为1.6~2.7 cm/月,平均2.2 cm/月;骨愈合时间为7~13个月,平均11.1个月。根据胫骨骨折疗效评定系统Johner-Wruhs评分评定疗效:优9例,良8例,中2例,优良率为89.5%。结论采用肢体短缩延长术治疗胫骨感染性骨缺损及慢性骨髓炎,可改善截骨端的直接对合,明显缩短骨对合端的愈合时间。

Methods from January 2011 to April 2016, 19 cases of tibial bone defect and chronic osteomyelitis were treated with limb shortening and lengthening. There were 13 males and 6 females, aged 22 to 62, with an average of 44 years old. The causes of injury were traffic accident injury (16 cases), crush injury (1 case) and high fall injury (2 cases). 18 cases were infected bone defect and osteomyelitis after external fixation of open leg fracture (Gustilo type 鈪,
