Abstract: The present invention is directed to a bone plate assembly including a bone plate, bone screws received in apertures in the assembly, and a screw retaining member fixed to the bone plate which covers at least a portion of the bone screws. When bone screws have been received by the bone plate and inserted into bone and/or tissue, the bone plate assembly can be used to fuse anatomical structures together, such as adjoining bones, or to heal a fracture in bone.

Abstract: A locking surgical tool handle system. The invention includes a surgical tool handle that has an elongated body portion with a pistol-type grip. The front end of the handle body has a tool retaining structure comprising a contoured engagement face and a movable tension bar with an engagement end. Projections on the engagement end of the tension bar fit within a receiving channel of a surgical tool, such as a broach or rasp. A locking mechanism is provided within the handle body, and is implemented with pivotable links attached to the tension bar. The locking mechanism has an unlocked position in which the engagement end of the tension bar is spaced away from the engagement face of the handle body, and an over-center locked position in which the engagement end of the tension bar is retracted toward the handle body. When the tool handle is placed in its locked position, the engagement end of the tension bar pulls an attached tool into tight contact with the engagement face of the handle body.

Abstract: A femoral stem prosthesis including a stem tapering from a proximal end to a distal end, and having a primary zone of taper and a secondary zone of taper. The secondary zone of taper, located at the distal end of the stem, has a larger angle of taper than that of the primary zone of taper, but substantially less than the taper in prior art stems. In the secondary zone of taper, the stem gradually tapers away from the femoral bone to avoid a sudden change in stress level in the bone at the distal stem tip, thus avoiding the incidence of thigh pain. The stem of the inventive prosthesis preferably includes longitudinal channels to increase its flexibility and preferably has a trapezoidal cross-sectional geometry to resist rotational forces and to provide multi-plane stability within the femur, thereby providing effective stress transfer to the femur.
