Lisfranc Injuries
Conditions
Brief summary
The purpose of this study is to compare arthrodesis of the first TMT-joint to extraarticular bridge plate fixation of the same joint in acute Lisfranc injuries.
Detailed description
We want to compare arthrodesis of TMT 1 to temporary bridge plating of TMT 1 in acute Lisfranc injuries where at least tarsometatarsal joints 1-3 are involved. We preform arthrodesis of TMT 2 and 3 in both groups.
Interventions
