伴第2跖骨基底部粉碎的Lisfranc损伤的手术治疗

目的 :探讨切开复位内固定治疗伴第2跖骨基底部粉碎的Lisfranc损伤的临床疗效。方法:选取2007年3月至2012年6月伴第2跖骨基底部粉碎的Lisfranc损伤患者7例,男5例,女2例;年龄22~51岁,平均42岁;扭伤4例,交通伤3例。Myerson分型:A型1足,B型3足,C型3足。在手术内固定同时,用克氏针从内侧楔骨至第2跖骨基底部固定Lisfranc韧带。术后采用美国足踝外科协会(AOFAS)足评分标准进行功能评估;术前、术后摄X线正位、侧位、斜位片及CT检查,进行影像学评估。结果:所有患者获得随访,时间12~20个月,平均16.8个月。末次随访AOFAS评分(86.1±5.5)分;优3例,良3例,一般1例。所有切口Ⅰ期愈合,未见皮肤坏死,感染,克氏针松动、断裂等并发症。结论:在手术内固定同时,用克氏针固定伴第2跖骨基底部粉碎的Lisfranc韧带损伤,有良好的临床疗效,可避免行关节融合术。

Surgical treatment for Lisfranc injuries accompanied by the base crashing of the second metatarsal bone

Objective:To discuss the clinical effects of open reduction and internal fixation (ORIF) for treatment of patients with Lisfranc injury combined the second metatarsal base comminuted fracture. Methods:From March 2007 to June 2012,7 patients with Lisfranc injury combined the second metatarsal base comminuted fracture were treated including 5 males and 2 female aged from 22 to 51 years old (means 42 years),4 of sprain and 3 of traffic injury. According Myerson classification,there was l case of type A,3 of type B and 3 of type C. Kirschner wire was used to fix Lisfranc ligament placing from the medial cuneiform bone to the second metatarsal base during the operation. After the operation American Orthopaedic Foot and Ankle Society (AOFAS) criteria system were applied to evaluate the foot and ankle function. Preoperative and postoperative AP,lateral and oblique X-ray and CT scan were collected for radiographic evaluation. Results:All patients were followed up from 12 to 20 months (16.8 months in average). According to AOFAS criteria system,3 cases were excellent result,3 good,1 fair. All the wounds were primary healing without skin necrosis,infection,Kirschner loose,broken,or other complications. Conclusion:Kirschner wire had good clinical efficacy for fixing Lisfranc ligament injury with the second metatarsal base comminuted fracture,and could avoid arthrodesis.
