Lisfranc 损伤手术治疗的原则是什么?

1. Rigid fixation for medial and middle columns; flexible and temporary fixation for lateral column
1. 内侧柱、中柱采用(跨关节螺钉或背侧桥接钢板)刚性固定,外侧柱采用柔性(克氏针)临时固定 。
2. If equinus contracture present, perform gastrocnemius recession when major contracture found
2. 如果有马蹄足挛缩,当发现较大的挛缩时,进行腓肠肌松解。
3. Exposure, reduction, and fixation generally proceed from proximal to distal and from medial to lateral
3. 显露、复位和固定一般从近端到远端、从内侧到外侧进行。
4. Dual incisions for 3-column injuries:
Dorsomedial – between 1st and 2nd
- Mobilize dorsalis pedis a. and deep peroneal n. lateral
- Interval between EHL and EHB
Dorsolateral – centered over 4th MT
- Common extensor tendons mobilized medial
- EDB split in line with fibers
4. 针对三柱损伤的双切口:
背内侧 - 在第一、二跖骨之间 ;
- 足背动脉和腓深神经拉向外侧 ;
- 间隙位于踇长伸肌(EHL )和 踇短伸肌(EHB )之间;
背外侧 - 以第四跖骨(MT )为中心 ;
- 伸肌总腱拉向内侧 ;
- 沿纤维方向劈开趾短伸肌(EDB) 。
5. Anatomic reduction under direct visualization
5. 直视下解剖复位 。
6. If cuboid is impacted restore the length of the lateral column
6. 如果骰骨有压缩,恢复外侧柱的长度 。
7. Postoperative nonWB for 8 weeks in cast, then walking boot, then supportive shoe wear and arch support by 3 months
7. 术后 8 周内石膏固定不得负重,然后穿行走靴,再穿支撑鞋、足弓支撑 3 个月。
