目的 探讨微型双边外固定支架结合有限内固定治疗严重中足骨折脱位的临床疗效.方法 对2009年5月至2012年8月收治的8例严重中足骨折脱位患者资料进行回顾性分析,男6例,女2例;年龄28 ～57岁,平均35.4岁.开放性损伤按Gustilo分型：Ⅱ型1例,Ⅲ型7例;中足骨折合并跗横关节脱位2例,跖跗关节脱位4例,跗横关节与跖跗关节均脱位2例.对骨折与脱位进行复位后,以微型双边外固定支架进行固定,恢复并保持足的内、外侧柱长度及正常足弓形态,必要时可结合有限内固定.术后12 ～16周拆除外固定支架,采用美国足踝外科协会（AOFAS）中足评分和疼痛视觉模拟评分（VAS）评估临床疗效. 结果 所有患者术后获10 ～24个月（平均13.4个月）随访.术后X线片示骨折脱位均获得良好复位,内、外固定拆除后无复位丢失.患者均能自主行走,随访期间未出现创伤性关节炎及足部畸形.术后3、6、12个月AOFAS中足评分平均分别为65.8、71.3、80.6分,术后3、6、12个月VAS评分平均分别为7.5、4.3、1.2分. 结论 对于严重中足骨折脱位,微型双边外固定支架结合有限内固定能很好地恢复内、外侧柱的长度及足弓的正常形态,维持复位稳定性,避免了足部畸形导致的功能障碍.
Objective To evaluate the clinical efficacy of external biplanar mini-fixator and limited internal fixation in treatment of severe midfoot fracture-dislocation.Methods Eight patients with severe midfoot fracture-dislocation were admitted from May 2009 to August 2012.They were 6 men and 2 women,28 to 57 years of age （average,35.4 years）.According to the Gustilo classification,there were one type Ⅱand 7 cases of type Ⅲ.Two cases of midfoot fracture were complicated with dislocation of the transverse tarsal joint,4 with dislocation of the tarsometatarsal joint,and 2 with dislocation of both the transverse tarsal joint and the tarsometatarsal joint.The external biplanar mini-fixator was applied to stabilize and maintain lengths of the medial and lateral columns and normal geometry of the foot arch after reduction of the fracture-dislocation.K-wires were used if limited internal fixation was necessary.The external fixator was removed at 12 to 16 weeks postoperatively.The clinical treatment efficacy was assessed by the American Orthopaedic Foot and Ankle Society （AOFAS） midfoot scale and the visual analogue scale （VAS）.Results The patients were followed up for an average of 13.4 months （from 10 to 24 months）.Postoperative radiological films showed fine reduction of the fractures and dislocations.No reduction was lost after removal of external and internal fixations.They were able to walk independently and had good functional recovery of the injured feet without traumatic arthritis during the follow-up period.Their average AOFAS scores were 65.8 at 3 months after operation,71.3 at 6 months and 80.6 at 12 months; the average VAS scores were 7.5 at 3 months,4.3 at 6 months,and 1.2 at 12 months,respectively.Conclusion In treatment of severe midfoot fracture-dislocation,external biplanar mini-fixator combined with limited internal fixation can perfectly reconstruct and maintain the medial and lateral columns and normal geometry of the foot arch,preventing functional disability caused by foot malformation.
