Biomechanical investigation of a novel ratcheting arthrodesis nail
BACKGROUND Knee or tibiotalocalcaneal arthrodesis is a salvage procedure, often with unacceptable rates of nonunion. Basic science of fracture healing suggests that compression across a fusion site may decrease nonunion. A novel ratcheting arthrodesis nail designed to improve dynamic compression is mechanically tested in comparison to existing nails. METHODS A novel ratcheting nail was design...
متن کاملBiomechanical comparison of a novel castless arthrodesis plate with T-plate and cross pin techniques for canine partial carpal arthrodesis.
OBJECTIVES To describe a novel canine castless partial carpal arthrodesis plate (par-CA) and its ex vivo biomechanical comparison with T-plate and cross pinning techniques for canine partial carpal arthrodesis. METHODS The three implant systems were applied to three cohorts of six forelimbs from Greyhounds euthanatized for reasons unrelated to the study. Intercarpal and carpometacarpal palmar...
متن کاملA biomechanical comparison of micromotion after ankle fusion using 2 fixation techniques: intramedullary arthrodesis nail or Ilizarov external fixator.
BACKGROUND In difficult ankle arthrodesis situations, intramedullary (IM) arthrodesis nails and external fixation are often considered in lieu of standard fusion techniques. The purpose of this study was to compare the amount of micromotion measured across an ankle fusion site stabilized with either an IM nail or with the Ilizarov external fixator. MATERIALS AND METHODS The relative bone mine...
متن کاملIntramedullary rod fixation compared with blade-plate-and-screw fixation for tibiotalocalcaneal arthrodesis: a biomechanical investigation.
BACKGROUND Achieving stable fixation when performing tibiotalocalcaneal arthrodesis can be challenging, especially in osteopenic bone. The purpose of the current investigation was to compare the stiffness and fatigue endurance of blade-plate-and-screw fixation with intramedullary rod fixation in a cadaveric model. METHODS In ten matched pairs of fresh-frozen cadaveric legs, a tibiotalocalcane...
متن کاملTibio-talo-calcaneal arthrodesis by a retrograde intramedullary nail.
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...
