Abstract: A multi-layer, fiber-reinforced composite orthopaedic fixation device having a design selected based on a desired characteristic of the orthopaedic fixation device. The design may be selected according to a model of the device, the model defining design constraints, and the design may comprise a pattern of the fiber angle for each layer. The selection of a design may be analyzed using finite element analysis to determine whether the design will comprise the desired characteristic.

Abstract: An instrument for reduction of a bone fracture is disclosed. The instrument includes an orthopaedic surgical implant (112), an implant member (190, 200, 270), and a driving member (180, 210, 260). The implant member (190, 200, 270) has a bone engagement portion (195, 203, 275) and a driven portion (197, 208, 278). The driving member (180, 210, 260) cooperates with the driven portion (197, 208, 278) to move the implant member (190, 200, 270) and reduce the fracture. Also disclosed is a sliding compression orthopaedic implant (300). The implant (300) comprises a first implant member (310), said first implant member (310) having a transverse hole (311); and a second implant member (312) connected to said transverse hole (311), said second implant member (312) having a shank (314), and said shank (314) having a bone engagement portion (316) at a first end portion (318) and a sliding compression member (320) at a second end portion (322).

Abstract: A drill guide and method for guiding placement of external fixation pins in the bone of a human limb to avoid an implanted intramedullary nail with the drill guide having a plurality of guide holes adapted to guide and receive a bone drill bit and bone pins. The drill guide also includes connecting for connecting the drill guide to one end of a drill guide handle connected to an intramedullary nail implanted in the bone and for aligning the guide holes in a fixed position relative to the nail so that the hole centerlines are oriented to avoid the nail.

Abstract: A device for treating and preventing injuries and contractures of the elbow joint, particularly supination-pronation contractures and proximal radial head fractures. The device includes bracing sections for fixing the device to the radius and the ulna, and for permitting movement of the attached radius continually along a path which is adapted and adjusted to be aligned with the kinematic axis of the proximal radial-ulnar joint.

Abstract: This invention relates to a device and method to externally fix bone fractures and bone deformities by moving an arc gear member, which is attached to a first bone segment, through an arc shaped path so as to place the first bone segment in the desired position relative to a second bone segment.

Abstract: A knee replacement prosthesis includes a tibial component and a femoral component with improved articular surface geometries. The improved geometries allow substantial internal rotation of the tibial component with respect to the femoral component during at least the first twenty degrees (20.degree.) of flexion. The tibial and femoral components are capable of flexing about an axis that reaches an inclination of from about ten degrees (10.degree.) to about fifty degrees (50.degree.) to the horizontal.
