Abstract: A compression hip screw plate for a hip screw system used to compress a proximal femur having a shaft with a lateral aspect and a neck extending from the shaft at an anteverted angle, both of which follow the anatomical contours of the proximal femur. The compression hip screw plate may include a side plate having a face side attachable to the lateral aspect of the shaft of the proximal femur; and a barrel having a first end extendable through the lateral aspect of the shaft of the proximal femur and into the neck of the proximal femur, and having a second end attached to the side plate with the first end extending away from the face side of the barrel at an anteverted angle. The compression hip screw plate may include a side plate with an anterior bow to match the natural femur.

Abstract: A variable length fixation device for insertion into a hole formed in two or more bone fragments has a barrel portion and a fastener element. The barrel portion is secured to an inside surface of the hole in a proximal one of the bone fragments. The fastener element is telescopically mounted to the barrel portion and is extendable into a distal one of the bone fragments. The assembly prevents lateral movements of the distal fragment, relative to the proximal fragment, while allowing axial relative movements (i.e., linear movements along the longitudinal axis of the fastener element) to occur. In a preferred embodiment, the fastener element is a cannulated bone screw having a hex-shaped cross-section on one end which is telescopically received into a hex-shaped interior of the hollow barrel portion. The two components are preferably permanently joined to form a one-piece assembly having a variable overall length.

Abstract: Fins on a hip prosthesis implant for anchoring the implant in good bone. The fins may be integral with, or separately attachable to, the implant. The fins extend radially outwardly beyond the perimeter of the implant from the front face longitudinally rearward.

Abstract: A total hip joint prosthesis including an acetabular cup implant of a construction permitting an initial adjustable disposition for optimum articulation with a prosthetic femoral ball mounted on a femoral prosthesis within a usual cup implant, the implant is of a trapezoidal or truncated cone shape, and external fins and a porous surface are provided to facilitate an initial and long-term positional fixation in the user, and to compensate for physiological bone changes over an extended period of time. The porous surface is preferred but an option is to use a plain surface implant used as a "press-fitted" device.

Abstract: A fenestrated hollow hip screw adapted for introduction therethrough of bone cement into a bone region affected by osteoporosis for increase of overall fixation of hip fractures, such as comminuted intertrochanteric types, and similar types of femoral fractures, even in the opposite distal end of the femur where such a device may be appropriately utilized.
