摘  要:目的探讨应用双平面截骨骨搬移治疗胫骨大段感染性骨缺损的临床疗效。方法回顾性分析2010年1月-2014年5月收治的胫骨大段感染性骨缺损患者12例,其中男8例,女4例;年龄16~65岁,平均40.9岁。致伤原因:交通伤8例,爆炸伤2例,砸伤2例。清创后皮肤缺损4.5cm×2.0cm~20.0cm×10.0cm,平均8.7cm×5.8cm。胫骨缺损6.0~20.0cm,平均11.0cm。所有患者应用Ilizarov技术进行双平面截骨骨搬移。3例骨缺损位于胫骨近端,在远端进行双平面截骨,向近端行同向逆行骨搬移;6例骨缺损位于胫骨中段,分别从胫骨近端和远端进行截骨,由两端向中央行相向骨搬移;3例骨缺损位于胫骨远端,在近端进行双平面截骨,向远端行同向顺行骨搬移。3例先行皮瓣转移术闭合伤口,1例胫骨部分短缩后伤口直接闭合,其余8例搬移过程中,伤口保持开放,直至断端对接。记录骨搬移时间、延长指数、创面愈合时间、延长区固化时间、缺损端对接后愈合时间、外固定时间和外固定指数。采用Ilizarov方法与应用学会(ASAMI)评分标准进行骨愈合和功能评价。结果外固定架拆除后随访(30.0±5.6)个月(12~36个月)。所有骨缺损和皮肤均顺利愈合,无感染复发或截肢。骨搬移时间(55.4±26.2)d(30~125d),延长指数(5.0±0.6)d/cm(3.9~6.3d/cm),创面愈合时间(3.6±1.4)个月(1.5—6个月),延长区固化时间(10.9±3.8)个月(4~18个月),缺损端对接后愈合时间(8.4±3.8)个月(3~16.5个月),外固定时间(12.5±4.1)个月(5~18个月),外固定指数(1.2±0.3)个月/cm(0.8~2个月/cm)。按ASAMI评分标准:骨愈合为优7例(58%),差5例(42%);功能结果为优9例(75%),良3例(25%)。结论双平面截骨骨搬移能明显缩短骨搬移时间�Objective To assess the efficacy of double-level bone transport for treatment of extensive post-infectious tibial bone defects. Methods From January 2010 to May 2014,12 consecutive patients suffering from massive postinfectious tibial bone defects were treated by the Ilizarov technique of double-level bone lengthening. The study population included 8 males and 4 females, with mean 40.9 years (range, 16-65 years). Mechanisms of initial injury included motor-vehicle injury in eight patients, explosive injury in two and crush-related injury in two. After bony resection for infection, skin defect was 8.7 cm ×5.8 cm (range, 4.5 cm ×2.0 cm-20.0 cm × 10.0 cm) and bone defect averaged 11.0 cm (range, 6.0-20.0 cm). All patients were treated with a double-level transport (three distal-to-proximal, six both-ends-to-center and three proximal-to-distal ). Three patients were candidates for flap coverage before bone transport because of large wounds, one patient had direct closure of the wound after tibial partly shortening, and the remaining patients kept the wound open during bone transport. Bone and functional results were evaluated according to the criteria given by Association for the Study and Application of the Method of Ilizarov (ASAMI). Results After removal of the apparatus, follow-up was (30.0 ± 5.6) months (range, 12-36 months). All patients aehieved complete union and successful eradieation of infeetion. Mean bone transport time was (55.4 ± 26.2)d (range, 30-125 d), with the lengthening index of ( 5.0 ± 0.6 ) d/cm ( range, 3.9-6.3 d/cm). Wound union time was ( 3.6 ± 1.4) months ( range, 1.5- 6.0 months). Mean consolidation time of the distraction gap was ( 10.9 ± 3.8) d ( range, 4.0-18.0 d). Mean union time of the docking site was (8.4± 3.8)months (range, 3-16.5 months). Mean external fixation time was (12.5 ± 4. 1 )months (range, 5-18 months), and mean external fixation index was ( 1.2 ± 0.3 ) months/cm( rang, 0.8-2 month
