摘　　要：目的探讨切开复位内固定治疗隐匿性跖跗关节损伤的临床疗效。方法 2002年7月-2009年7月,收治47例隐匿性跖跗关节损伤患者。男31例,女16例;年龄19～66岁,平均35.6岁。交通事故伤27例,高处坠落伤11例,运动伤6例,压砸伤3例。左足18例,右足29例。单纯内侧柱损伤6例,内侧柱伴中间柱损伤24例,中间柱伴外侧柱损伤13例,三柱损伤4例。患者均存在跖骨基底部骨折。受伤至手术时间为4～21 d,平均8.6 d。手术采用1～2个足背侧纵形切口,复位后用小钢板、螺钉、骑缝钉、克氏针固定内侧柱及中间柱,外侧柱均用克氏针固定。结果 1例术后切口感染,经封闭式负压引流2周后采用腓肠神经营养血管皮瓣移位修复创面;其余患者切口均Ⅰ期愈合。术后32例获随访,随访时间12～75个月,平均28.3个月。骨折于术后9～15周愈合,平均12.3周。末次随访时,15例出现中足骨关节炎表现,但无需行关节融合术。采用美国矫形足踝协会(AOFAS)的中足评分标准评价疗效,获优9例,良16例,一般4例,差3例,优良率为78.1%。随访期间均未出现跖跗关节再脱位。结论对跖骨基底部骨折应给予足够重视,术中探查有助于发现隐匿性跖跗关节损伤,应根据不同损伤类型及伴发损伤,采用合理的固定方式,尽量做到解剖复位、可靠固定,重建中足内在稳定是获得满意疗效的关键。Objective To evaluate the clinical effectiveness of open reduction and internal fixation in the treatment of occult Lisfranc injury. Methods Between July 2002 and July 2009, 47 patients with occult Lisfranc injuries underwent open reduction and internal fixation. There were 31 males and 16 females with an average age of 35.6 years （range, 19-66 years）. Injuries were casused by traffic accident in 27 cases, falling from height in 11 cases, sport in 16 cases, and crush in 3 cases. The locations were left foot in 18 cases and right foot in 29 cases. Simple medial column was involved in 6 cases, medial and middle columns in 24 cases, middle and lateral columns in 13 cases, and three columns in 4 cases. Base fractures of metatarsal bone were identified in all cases. The time from injury to operation was 4-21 days （mean, 8.6 days）. The unstable Lisfranc joints were reduced and fixed by plates, screws, staples, and Kirschner wire through 1 or 2 longitudinal dorsal incisions. Results One case had infection and wound was repaired with flap at 2 weeks after operation; the other wounds healed primarily. Thirty-two patients were followed up 28.3 months on average （range, 12-75 months）. The mean time of fracture healing was 12.3 weeks （range, 9-15 weeks）. Osteoarthritis at midfoot was found in 15 cases at last follow-up and arthrodesis was not needed. The results were excellent in 9 cases, good in 16 cases, fair in 4 case, and poor in 3 cases according to American Orthopaedic Foot and Ankle Society （AOFAS） midfoot score system; the excellent and good rate was 78.1%. No re-dislocation occurred during the follow- up. Conclusion More attention should be paid to base fractures of metatarsal bone, operative exploration is conducive to diagnosis of occult Lisfranc injury. Suitable internal fixation should be selected according to injury type and concomitant injury. Anatomical reduction and stable fixation are the keys to reconstruct the joint stabil ity in the initial treatment of occult Lisfranc injury.
