Background: Surgical fixation of distal radius fractures with Dorsal Bridge Plating (DBP) has been proposed to allow early weight bearing/mobilization of polytrauma patients. However, there is a lack of biomechanical studies supporting the use of DBP with crutches. We hypothesized that a 3.3 mm DBP is comparable to a Volar Locking Plate (VLP) for distal radius fractures and able to allow for immediate weight bearing.
Methods: VLPs and DBPs were applied to cadaver forearms with a dorsal wedge osteotomy in an axially loaded crutch bearing model. Displacement was measured as specimens were incrementally loaded. Failure was defined as 2 mm of fracture gap displacement. T-tests were used to compare the force at failure for each group and to the target thresholds of 200 N and 400 N. Linear regression analysis was used to determine the association .. View More»
