摘要:

背景:跖跗关节(Lisfranc关节)损伤为临床较为少见的疾病,发病率较低,误诊率也较高。目前多采用切开复位内固定方法治疗,但是该类型损伤术后长期随访观察较少,对于术后足部运动功能也没有深入的研究。
目的:评价Lisfranc损伤金属植入物内固定后患者足部功能的变化。
方法:对18例Lisfranc损伤的患者采取金属植入物内固定治疗,内固定物包括克氏针、螺钉及钢板,术后6-8周开始拄拐杖下地锻炼。术后1年进行随访,采用比利时Footscan系统测定患足足底压力分布,美国矫形足踝协会评分系统对患足术后的功能进行评价,以期评估术后1年患足的稳定性和运动功能。
结果与结论:Lisfranc损伤内固定修复后1年,骨折均获骨性愈合,患足在第4跖骨底(M4)和第5跖骨底(M5)峰值压力明显增高(P < 0.05),第5跖骨底(M5)及足中部底(MID)冲量高于健侧(P < 0.05)。患足美国矫形足踝协会评分平均为(87.26±21.13)分,优良率占到89%。提示Lisfranc损伤金属植入物内固定修复后患足的主要负重由前足内侧转移到外侧,其余压力变化不明显,患足的功能恢复满意。由此可见Lisfranc损伤内固定治疗力争达到解剖复位的同时积极进行康复训练,能够基本保证足部功能恢复,使重建得跖跗关节复合体在力学方面达到新的平衡。

Abstract:

BACKGROUND: Lisfranc injury is rarely seen in clinical practice, with a low incidence and a high misdiagnosis rate. At present, open reduction and internal fixation is the major treatment, but there is little evidence available on the long-term follow-up following injury and foot motor functions following surgery.
OBJECTIVE: To evaluate the change of foot functions after metal graft internal fixation in patients with Lisfranc injury.
METHODS: Eighteen patients with Lisfranc injury were treated with internal fixation of metal grafts, such as Kirschner wire, screws and steel plate. At 6-8 weeks postoperatively, patients began to walk with crutches. After 1 year follow-up, the Footscan balance system and AOFAS scores were applied to evaluate the foot stability and function of patients.
RESULTS AND CONCLUSION: After 1 year of internal fixation, all bone fractures were healed, the peak pressure of affected foot in the fourth metatarsal (M4) and the fifth metatarsal (M5) was significantly increased (P < 0.05), and the impulse in the fifth metatarsal (M5) and mid-foot bottom (MID) was higher than the contralateral side (P < 0.05). The AOFAS score of affected foot was 87.26 ± 21.13 points, the rate of excellent and good efficacy accounted for 88.9%. Internal fixation can rebuild Lisfranc complex stability, the body weight is transferred from the inside to the outside in the front foot, and the remaining pressure did not change significantly, thus the foot function is recovered satisfactorily.
