Lisfranc osteoarthritis

clinical evaluation of tarsometatarsal joint arthrodesis with Agraf implant

Abstract

Introduction: The arthrodesis has a high success rate for treatment of sintomatic arthritis of the TMTT, however it presents an incidence of 5% to 15% of non-union or malunion. The ideal method for fixation of arthrodesis of the Lisfranc joint complex should ideally provide stability, high compression capacity and minimum surgical aggression for soft tissues. Objective: To describe the clinical outcomes after stabilization of the tarsometatarsal arthrodesis with staples. Methods: Stabilization of the tarsometatarsal joints with staples seem to be a reproducible and stable osteosynthesis technique, which allows good clinical results, similar to other techniques, with low complication rates. Results: Eleven patients with diagnosed with posttraumatic tarsometatarsal arthritis, were underwent a Lisfranc arthrodesis and osteosynthesis with Agraf Staple. The follow-up period ranged Between 1 to 3 years, all patients returned to working with minimal functional activity limitation. None superficial nerve injury, dystrophy, or loosening of the implant was observed in our series. Conclusion: The fixation of tarsometatarsal joints with staples shown to be reproducible, allows stability and presents clinical outcomes with low rates of complications in consolidation, wounds and peripheral nerves.
