Failed AgilityTM LP Total Ankle Replacement Salvaged with Tibio-Talo- Calcaneal Arthrodesis and Vascularized Pedicled Medial Malleolus and Fibula Onlay Bone Grafts

چکیده
Controversy exists regarding the most predictable salvage for failed total ankle replacement. Revision total ankle replacement with soft-tissue release/reconstruction or explantation with tibio-talo-calcaneal arthrodesis with bulk structural allograft are the most commonly performed approaches. Tibio-talo-calcaneal arthrodesis with bulk structural allograft has a high complication rate; however, augmentation with vascularized pedicled onlay bone grafts may improve osseous union and functional limb salvage. This manuscript presents the revision of a failed AgilityTM LP total ankle replacement system with severe >45° varus ankle deformity that was salvaged with tibio-talocalcaneal arthrodesis, bulk femoral head structural allograft and vascularized pedicled medial malleolus and fibula onlay bone grafts. At short-term 1.5-years follow-up the patient had a well-balanced and painless foot/ankle and return of a functional lower limb.

Arthrodesis Using Pedicled Fibular Flap After Failed Infected Knee Arthroplasty
OBJECTIVE Severe bone loss associated with failed revision total knee arthroplasty is a challenging scenario. The pedicled fibular flap is a method to obtain vascularized bone for use in knee arthrodesis after failure of a total knee arthroplasty, with substantial loss of bone. METHODS We report 2 successful knee arthrodeses using this method in patients with infected, failed multiply revised...

BACKGROUND The paper presents the results of tibio-talo-calcaneal fusions using Retrograde Nailing System and Bone Grafting. MATERIAL AND METHODS From May 2006 to January 2008, we performed 13 fusions in 11 consecutive patients with advanced ankle and hindfoot disease. Patients underwent 13 tibiotalocalcaneal fusions (2 patients had initial tibiotalocalcaneal fusion using screws and subsequen...
متن کاملATFL and ATiFL rupture have different mechanisms in ankle instability
INTRODUCTION: Anterior talofibular ligament (ATFL) was frequently injured by sports and recreational activities. On the other hand, anterior tibiofibular ligament (ATiFL) injury, which was less frequently than ATFL injury, was often overlooked or misdiagnosed for ATFL injury, by follow reasons; those two ligaments were nearly positioned each other, and observed increase of talar tilt angle (TTA...

1 Sir: D of the distal fibula can result in ankle instability.1 Ankle reconstruction for defects involving the distal fibula include arthrodesis, nonvascularized autografts, and free flaps.2 Pedicled flaps have some advantages over free flaps, including decreased operative time and decreased postoperative complications.3 Pedicled retrograde fibula flaps have been previously described for tibial...
