Biomechanical evaluation of methods of internal fixation of the distal humerus.

abstract：OBJECTIVES:The stiffness of locking plates provide increased stability for early fracture healing but may limit late interfragmentary motion (IFM) necessary for secondary bone healing. An ideal plating construct would provide early rigidity and late flexibility to optimize bone healing. A novel screw plate construct ut...
