Summary
Lisfranc injuries, or tarsometatarsal dislocations, are severe midfoot injuries. Early diagnosis and anatomic reconstruction using screws for temporary fixation offer better outcomes than K-wires.
Area of Science:
- Orthopedic Surgery
- Foot and Ankle Trauma
- Radiology
Background:
- Tarsometatarsal (Lisfranc) injuries are severe midfoot injuries that can lead to chronic pain and arthritis if missed.
- Accurate diagnosis is crucial for effective treatment and preventing long-term disability.
Purpose of the Study:
- To outline the diagnostic and treatment principles for Lisfranc injuries.
- To compare the efficacy of screw fixation versus K-wire fixation for temporary stabilization.
Main Methods:
- Review of diagnostic imaging including X-rays, CT scans, and MRI.
- Surgical reconstruction principles focusing on anatomic reduction and alignment.
- Comparison of temporary fixation methods: small fragment positioning screws versus K-wire arthrodesis.
Main Results:
- Anatomic reduction and alignment are essential for functional outcomes.
- Reduction of the second metatarsal ray is the primary step in surgical reconstruction.
- Temporary fixation with screws demonstrates advantages over K-wire arthrodesis for stability until healing.
Conclusions:
- Prompt diagnosis and surgical intervention are vital for managing Lisfranc injuries.
- Anatomic reconstruction following established principles is key to successful outcomes.
- Screw fixation provides superior temporary stability compared to K-wire fixation in Lisfranc injury repair.
