摘要:

背景:陈旧的踝关节外侧副韧带损伤常常采用Chrisman-Snook术式,但该术式需要牺牲部分自体腓骨短肌腱,使腓骨短肌腱外翻足的功能受到影响。
目的:在前人研究基础上,观察应用同种异体肌腱与锚钉修复重建陈旧踝关节外侧副韧带损伤的效果。
方法:选择踝关节外侧副韧带损伤患者17例,病程长3~6个月。所有患者均应用同种异体肌腱+锚钉修复踝关节外侧副韧带。术中应用4.5 mm直径的钻头在外踝处打孔,在距腓韧带的距骨止点处拧入锚钉一枚,在跟骨跟腓韧带止点处拧入锚钉一枚,然后将异体肌腱在外踝骨孔处穿过,维持踝关节于伸曲中立位和中度外翻位,将肌腱的两端分别用锚钉的尾线缝合固定,术后石膏托固定踝关节于伸曲中立位和轻度外翻位。术后观察伤口愈合情况、AOFAS评分及应力X射线平片结果。
结果与结论:17例患者均未出现排斥反应,创面均一期愈合。术后6,12,24个月复查,患者AOFAS评分显示踝关节功能明显改善,无踝关节不稳,应力位置的距骨倾斜角度平均值及距骨的移动距离平均值明显减小,踝关节功能较好,外形满意。可见,应用同种异体肌腱与锚钉重建踝关节外侧副韧带陈旧损伤,手术剥离软组织范围小,不损伤正常自身结构,可维持踝关节正常形态,恢复踝关节功能。

Abstract:

BACKGROUND: Obsolete lateral ankle ligament injury is frequently treated by Chrisman-Snook operation. However, this operation destructs some peroneus brevis tendon, and affects the function of peroneus brevis tendon for foot valgus.
OBJECTIVE: Based on previous research, to investigate the effect of allogeneic tendon for reconstruction of ankle lateral ligaments.
METHODS: A total of 17 cases of ankle lateral ligament injured were selected, with a course of disease from 3 to 6 months. All lateral ligaments were reconstructed by allogeneic tendon & anchors. During the operation, a drill, 4.5 mm diameter, was used to drill a hole on the lateral ankle; one anchor was drilled into the talus at the end of anterior talofibular ligament, another one was threaded on the calcaneus; the allogeneic tendon was permeated through the hole on the lateral ankle, maintaining ankle neutral and moderate valgus position. The allogeneic tendon was sutured with the thread of the anchors. Following operation, the ankle was fixed in neutral position and slightly valgus position; wound healing, AOFAS score and stress radiograph were observed.
RESULTS AND CONCLUSION: All 17 patients showed no rejection, and the wound healing well at the primary stage. At 6, 12, 24 after operation, all patients were followed-up. According to AOFAS criteria, function of ankle in all patients was significantly improved. No patients complained of instability of the ankle, and stress radiograph confirmed this improvement. Reconstruction of lateral ligaments of the ankle with allogeneic tendon and anchors is a practical treatment, which restores stability and function of ankle without long incision or damaging normal tendons.
