Open fractures of tibia have posed great difficulty in managing both the soft tissue and the skeletal components of the injured limb. Gustilo Anderson III B open tibial fractures are more difficult to manage than I, II, and III A fractures. Stable skeletal fixation with immediate soft tissue cover has been the key to the successful outcome in treating open tibial fractures, in particular, Gustilo Anderson III B types. If the length of the open wound is larger and if the exposed surface of tibial fracture and tibial shaft is greater, then the management becomes still more difficult.
Thirty six Gustilo Anderson III B open tibial fractures managed between June 2002 and December 2013 with "fix and shift" technique were retrospectively reviewed. All the 36 patients managed by this technique had open wounds measuring >5 cm (post debridement). Under fix and shift technique, stable fixation involved primary external fixator application or primary intramedullary nailing of the tibial fracture and immediate soft tissue cover involved septocutaneous shift, i.e., shifting of fasciocutaneous segments based on septocutaneous perforators.
Primary fracture union rate was 50% and reoperation rate (bone stimulating procedures) was 50%. Overall fracture union rate was 100%. The rate of malunion was 14% and deep infection was 16%. Failure of septocutaneous shift was 2.7%. There was no incidence of amputation.
Management of Gustilo Anderson III B open tibial fractures with "fix and shift" technique has resulted in better outcome in terms of skeletal factors (primary fracture union, overall union, and time for union and malunion) and soft tissue factors (wound healing, flap failure, access to secondary procedures, and esthetic appearance) when compared to standard methods adopted earlier. Hence, "fix and shift" could be recommended as one of the treatment modalities for open III B tibial fractures.
胫骨开放性骨折在处理受伤肢体的软组织和骨骼部分时都带来了巨大困难。与I型、II型和III A型骨折相比,Gustilo Anderson III B型胫骨开放性骨折更难处理。采用稳定的骨骼固定并立即覆盖软组织一直是治疗胫骨开放性骨折(尤其是Gustilo Anderson III B型骨折)取得成功结果的关键。如果开放性伤口长度更大,并且胫骨骨折和胫骨干的暴露面积更大,那么处理起来就更加困难。
回顾性分析了2002年6月至2013年12月间采用“固定并转移”技术治疗的36例Gustilo Anderson III B型胫骨开放性骨折。采用该技术治疗的所有36例患者的开放性伤口(清创后)均大于5 cm。在“固定并转移”技术下,稳定固定包括对胫骨骨折进行一期外固定架固定或一期髓内钉固定,立即覆盖软组织包括隔皮瓣转移,即基于隔皮穿支转移筋膜皮瓣。
一期骨折愈合率为50%,再次手术率(骨刺激手术)为50%。总体骨折愈合率为100%。畸形愈合率为14%,深部感染率为16%。隔皮瓣转移失败率为2.7%。无截肢病例。
与早期采用的标准方法相比,采用“固定并转移”技术治疗Gustilo Anderson III B型胫骨开放性骨折在骨骼因素(一期骨折愈合、总体愈合、愈合时间和畸形愈合)和软组织因素(伤口愈合、皮瓣失败、二次手术的可及性和美观外观)方面取得了更好的结果。因此,“固定并转移”可被推荐为开放性III B型胫骨骨折的治疗方式之一。
