Abstract: Surgical clamping instruments include a distal portion having distal tips configured to be driven to provide clamping force to multiple tissue pieces; a proximal portion including a compression actuator configured for operation by a user to drive the distal tips to apply compression force to the tissue pieces, and a shear actuator configured for operation by the user to drive the distal tips to apply shear force to the tissue pieces; and an intermediate portion interconnecting the proximal and distal portions.

Abstract: A femoral stem type hip joint prosthesis system includes a series of shoulderless or collarless, anatomically contoured stems of differnt sizes for firm implantation into the intramedullary canal of the femur; and a series of head units having variable neck lengths so that anatomically correct positioning of the head of the prosthesis may be obtained with varying depths of implantation of the stem, and normal anatomical variations. The stem may be smoothly tapered, and may have a rectangular cross-sectional configuration with substantially greater width in the medial/lateral direction than in the anterior/posterior direction. The stem may have a medical curvature of approximately six inches and a lateral curvature of approximately three inches adjacent its proximal or upper end, and this curved upper portion blends smoothly into a tapered lower section, having a centerline which is straight, and with the implanted portion of the stem being in the order of four and one-half inches or more in length.

Abstract: An artificial hip joint includes a socket or acetabular portion and a femoral portion secured to the upper leg bone or femur. A continuous metal acetabular cup for an artificial hip joint is provided with a right cylindrical portion and chamfered dome which is of porous titanium or other suitable material, including a coating of either sintered fibers or sintered small particles such as spheres, to encourage early bone ingrowth, following force fit insertion of the cup into the acetabulum. A plastic insert having a central recess for receiving the femoral ball, is inserted into the cup and includes interlockng elements for holding the plastic insert firmly into the metal cup and against rotation, and a flange extending over the lip of the metal cup to preclude metal to metal contact.
