    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 locking device includes a locking sleeve and a handle. The locking sleeve defines a pin channel and a plurality of resilient locking catches. The distal end of the sleeve includes a tip having a cutting edge and a pin guide adapted to be located about a portion of the diameter of a fixation pin. The locking sleeve is used to stabilize the location and orientation of a fixation pin implanted in a bone.

    摘要： A dorsal fracture is treated from the volar side by using a T-shaped plate opposite the fracture. The plate is positioned against the volar side of the radial bone, a plurality of bone screws secure the plate along a non-fractured portion of the radial bone, and a plurality of bone pegs extend from the plate and into the bone fragments of the fracture. A support portion of the plate is provided distal of the bone pegs and supports comminuted bone fragments. One or more channels are optionally provided in the plate to receive wires which are adapted to anchor distal bone fragments to the plate. The plate is adapted in strength and materials to withstand the large bending forces thereon.

    摘要： A volar fixation system includes a T-shaped plate intended to be positioned against the volar side of the radial bone, a plurality of bone screws for securing the plate along an non-fractured portion of the radial bone, and a plurality of bone pegs which extend from the plate and into bone fragments of a Colles' fracture. The plate includes including a plurality of screw holes and a plurality of threaded peg holes. The bone pegs can be articulated through a range of angles within respective peg holes and fixed at a desired angle within the range. 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.
