Stabilization of distal femur fractures with intramedullary nails and locking plates: differences in callus formation.
OBJECTIVES This study compared callus formation in distal femur fractures stabilized with locking plates and intramedullary nails to test the hypothesis that locking plates induce less fracture callus than IM nails. DESIGN Retrospective case matched study. SETTING Two orthopaedic trauma centers. PATIENTS 174 distal femur fracture were reviewed to extract cases treated with retrograde IM n...
متن کاملComparison of 4 Methods for Dynamization of Locking Plates: Differences in the Amount and Type of Fracture Motion
BACKGROUND Decreasing the stiffness of locked plating constructs can promote natural fracture healing by controlled dynamization of the fracture. This biomechanical study compared the effect of 4 different stiffness reduction methods on interfragmentary motion by measuring axial motion and shear motion at the fracture site. METHODS Distal femur locking plates were applied to bridge a metadiap...
متن کاملAn internal locking plate to study intramembranous bone healing in a mouse femur fracture model.
In most murine fracture models, the femur is stabilized by an intramedullary implant and heals predominantly through endochondral ossification. The aim of the present study was to establish a mouse model in which fractures heal intra-membraneously. Femur fractures of 16 SKH-mice were stabilized by an internal locking plate. Femur fractures of another 16 animals were stabilized by an intramedull...
متن کاملFar Cortical Locking Enables Flexible Fixation While Maintaining Construct Strength
INTRODUCTION: The stiffness of a fixation construct affects the mechanism and progression by which a fracture heals. Locked plating constructs have improved fixation strength in weak bone, but their relatively high stiffness may suppress interfragmentary motion (IFM) to a level insufficient for optimal promotion of secondary bone healing.[1] This is especially of concern when locked plates are ...
متن کاملLocked plating of distal femur fractures leads to inconsistent and asymmetric callus formation.
OBJECTIVES Locked plating constructs may be too stiff to reliably promote secondary bone healing. This study used a novel imaging technique to quantify periosteal callus formation of distal femur fractures stabilized with locking plates. It investigated the effects of cortex-to-plate distance, bridging span, and implant material on periosteal callus formation. DESIGN Retrospective cohort stud...
