    摘要: A fracture fixation plate system for use on a long bone having a metaphysis and a diaphysis, includes at least one end plate having a head portion for the metaphysis, and at least one fragment plate having a first end and a second end with a plurality of screw holes therebetween. The end plate includes mating structure adapted to mate with and securely couple to at least one end of the at least one fragment plate. The system preferably includes several end plates and fragment plates to accommodate anatomy of various sizes.

    摘要: A bone fixation system includes a plate and a set of fixation locking screws. The plate defines a set of locking screw holes each having an internal thread. Each respective locking screw has a head with an external structure that is adapted to self-tap into the internal thread of a given locking screw hole to secure the respective first-type fixation locking screw at an surgeon-directed angle relative to the plate. This angle is defined during forcible insertion and rotation of the respective locking screw into the given screw hole. The system may also include unidirectional locking screws. In a preferred embodiment the plate and first-type of screw are made of different metals, with the plate made of titanium alloy and the screw made of cobalt chrome alloy.

    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 polyaxial locking screw system includes a bone plate defining a plate hole with an inner spherical surface and a relatively harder split polyaxial bushing with a outer spherical surface provided within the plate hole for receiving a bone screw. In one embodiment, the plate is formed from titanium alloy, while the bushing is formed from a cobalt chrome alloy. The outer surface of the polyaxial bushing includes a plurality of spikes. When the screw is inserted into the bushing, since the bushing material is considerably harder than the plate material, the forceful expansion of the bushing during screw insertion causes the spikes to penetrate into the inner spherical surface of the hole, thereby increasing the frictional engagement of the bushing to the plate to lock the screw at a desired angle.
