Biomechanical Benefits of the VariAx Distal Lateral Fibula Plate
نویسندگان
چکیده
Distal fibula fractures are the most common injury of weight bearing bones. Several studies have shown the benefit of locking plates especially in osteoporotic bone. The aim of this biomechanical study was to test the anatomically shaped VariAx Distal Lateral Fibula Plate in comparison to a commonly used 1/3 Tubular Plate. The implants were assembled to bone surrogates simulating a comminuted fracture. For determination of the implant strength a strong bone surrogate was chosen, while for determination of the cut-out behavior a weak surrogate simulated poor quality bone. The VariAx plate showed higher bending fatigue strength and also higher cut-out strength than the 1/3 Tubular Plate. Therefore, the VariAx plate provides potential biomechanical benefits.

Development of novel implants in orthopaedic trauma surgery is based on limited datasets of cadaver trials or artificial bone models. A method has been developed whereby implants can be constructed in an evidence based method founded on a large anatomic database consisting of more than 2.000 datasets of bones extracted from CT scans. The aim of this study was the development and clinical applic...

متن کاملA contoured locking plate: Biomechanical evaluation of an osteosynthesis for osteoporotic ankle fractures
Introduction Ankle fractures involving the distal fibula belong to the most common fractures. Operative treatment is indicated in unstable ankle fractures by open reduction and internal fixation with plate and screws. Especially in the elderly, the osteoporotic bone provides reduced stabilization of this fixation. Therefore, an implant providing improved mechanical stabilization could allow a m...
