    摘要： A bone plate includes at least one torsional modification feature (TMF). Each TMF is structured to decrease the torsional rigidity of the plate relative to longitudinally opposite portions, but may be modified to increase the torsional rigidity thereat. Each TMF is defined by beams contiguous with the lateral sides of the plate, and an opening extending laterally therebetween. In a preferred embodiment, opposed projections extend into the opening to define threaded discontinuous wall portions for receiving an insert, such as a set screw. In one embodiment, bioabsorbable and/or bioactive inserts may be used to temporarily increase the torsional rigidity of the plate during initial fixation and thereafter have reduced torsional rigidity to mimic normal callus. The plate is preferably used with fixed angle fasteners that may be subject to high torsional loads post-operatively.

    摘要： A fixation system includes a plate intended to be positioned against a bone, a plurality of bone screws for securing the plate along an non-fractured portion of the bone, and a plurality of bone pegs which extend from the plate and into bone fragments of the fracture to provide a supporting framework. The pegs can be oriented at various angles relative to an axis normal to the lower surface of the plate. For each peg, once the peg has been appropriately positioned within the peg hole, a set screw is threaded into the peg hole and tightened, thereby securing the peg in the selected orientation.

    摘要： A fixation device is provided which includes a proximal nail portion and a distal plate portion. The nail portion includes a flexible tapered section, and a rigid distal section larger in diameter and is adapted to be inserted into a medullary canal of a fractured bone. The plate portion has a low, narrow profile and includes three longitudinally displaced peg holes, each of which is adapted to orient a peg in a different orientation from the others. The plate portion is adapted to be positioned on the outside of a fractured bone when the nail portion is within the medullary canal. The device provides the benefits of both an intramedullary nail and a bone plate in a single device. The fixation device permits a minimally invasive treatment of the metaphyseal fractures that may otherwise be undertreated.
