[Arthrodesis of the lisfranc joint as salvage procedure after trauma injury].

Dislocations and fractures of the tarsometatarsal joints (Lisfranc joint) are rare, often non properly diagnosed and treated. Lack of proper diagnosis and postponed operative treatment causes painful deformity of the foot. There are presented results of operative treatment in 6 patients (6 feet) with fracture/dislocation of the Lisfranc joint. In all of them arthrodesis as salavage procedure was performed. Age at the fracture/dislocation ranged from 13 to 58 years. After trauma no one was treated operatively. Injury was overlooked in 2 patients. Indications for arthrodesis were pain causing limping as well flattening and abduction deformity fo the foot. Arthrodesis was performed from 1 to 39 years after trauma. It was closing wedge resection of the Lisfranc joint, stabilization with Kischner wires for 6 weeks and below knee plaster cast for 3 months. Follow-up ranged from 14 to 52 months. Functional results in AOFAS scale ranged from 6 do 90 points (mean 63 points) of 100. Subjective results ranged from 1 to 8 points (mean 5.6 points) of 10. Two females were not satisfied with the results of treament.
