  • Patent number: 4895141
    Abstract: A unilateral external fixation device comprises a distal frame and a proximal frame interconnected by a hinge formed of mating, partially spherical-shaped surfaces which permits relative movement of the distal frame and proximal frame. Each of the frames includes one or more pin clamps which mount half pins inserted with the proximal or distal segments of a fractured bone to immobilize the bone segments and permit reduction of the fracture. The focal point of the partially spherical-shaped surfaces of the hinge is positioned in direct alignment with the fracture, preferably in a vertical plane passing through the fracture transverse to the longitudinal axis of the bone, so that manipulation of one or both of the distal and proximal frames permits a relatively slight and precise movement of the bone segments connected thereto by the half pins to ensure proper reduction of the fracture.

  • Patent number: 4895573
    Abstract: A femoral-side hip-joint prosthetic device for use in hip-joint replacement. The device includes an elongate stem whose surface defines maximally spaced infero-medial and supero-lateral surface curves, and which is characterized by a surface rotation which carries the supero-lateral surface curve about 15.degree.-30.degree. forward with respect to the infero-medial surface curve, on progressing upward along the upper surface portion of the stem, with the device in operative position. The rotation of the stem surface produces a close approximation to the cavity formed in the proximal femur by removal of the cancellous bone in the natural cavity formed by a wall of densified cancellous bone. A 3.degree.-15.degree. proximal anteversion of the neck is adapted to place a hip-joint ball carried on the stem at a position closely approximating that of the head in the natural femur.

  • Patent number: 4621629
    Abstract: A compression hip screw to aid in healing of a fracture between the neck and head of a femur includes a hollow lag screw having a threaded inner end adapted to be inserted through the neck and into the head of the femur to span the fracture therebetween, a spring assembly slidably disposed within the lag screw and attached thereto, a side plate having a barrel adapted to fit over the outer end of the lag screw and a shank section for mounting to the lateral aspect of the femur, and a compression screw insertable through the barrel and into threaded engagement with the spring assembly. The compression screw seats in a recess formed at one end of the barrel and is rotatable to move the spring assembly along its threaded shaft toward the side plate. In turn, the lag screw connected to the spring assembly is urged toward the side plate which forces the femoral head against the neck of the femur to apply a compression force at the fracture therebetween.

  • Patent number: 4231122
    Abstract: A prosthesis for knees and other joints comprises two portions which are disposed side by side and which are at least partially spaced apart from one another. Each portion of the prosthesis includes a pair of spaced apart, relatively inextensible primary components. Disposed between and spaced from the primary components in each portion of the prosthesis is a pivot member. Each pivot member is resiliently secured to the two corresponding primary components of its portion of the prosthesis so as to permit and accommodate relative rotation between the pivot member and the primary components. As a result, the two primary components of each portion of the joint prosthesis can rotate toward and away from one another about an axis that is disposed at least adjacent to and at least approximately parallel to a central axis of the corresponding pivot member. The pivot member and the primary components of each portion of the prosthesis are preferably secured together by one or more bodies of elastomer.

  • Patent number: 4204284
    Abstract: A joint prosthesis comprises two relatively inextensible primary components that are spaced apart from one another. Disposed between and spaced from each of the primary components is a pivot member that is also fabricated of relatively inextensible material. When viewed in section taken normal to its central longitudinal axis, the pivot member has two discrete arcuate surfaces that are spaced apart from one another about the circumference of the pivot member. One of the primary components of the prosthesis is resiliently secured to one of the arcuate surfaces of the pivot member, while the other primary component of the prosthesis is resiliently secured to the other arcuate surface of the pivot member. The resilient connections between the pivot member and the primary components permit relative rotation between the pivot member and each of the primary components.

  • Patent number: 4006892
    Abstract: A compression mounting comprises a body of elastomer and a pair of load-transmitting devices that engage and cover two opposed and spaced apart surfaces of the elastomeric body. The two load-transmitting devices are disposed and configured to expose a circumferential surface of the body of elastomer. At least a circumferential portion of the surfaces so exposed is completely covered and enclosed by a shell or housing. The shell includes a filamentary structure that provides a plurality of substantially parallel and juxtaposed filament portions oriented to circumscribe the surface of the elastomeric body. The filament portions are less extensible than the elastomer of the elastomeric body. A matrix material encases the filament portions and flexibly bonds adjacent filament portions to one another. The shell snugly fits the surface of the elastomeric body and is more resistant to circumferential expansion than the elastomeric body.
