Abstract: Implants and methods are presented for surgically repairing a hip joint with a proximal femoral prosthesis that comprises femoral head component and a femoral stem component. The femoral stem component comprising a neck portion, a flange portion, a transitional body region and an elongated stem. The femur is prepared for implantation of the femoral hip prosthesis by resecting the proximal femur and reaming a symmetric intramedullary cavity in the femur. The femoral hip prosthesis is then inserted the on the resected femur and in the intramedullary cavity. The femoral hip prosthesis elastically deforms when loaded during use to apply dynamic compressive loads and displacement to the calcar region of the resected proximal femur.

Abstract: A bone plating system invention is shown comprising a bone plate and bone fasteners. The bone plate has a top portion, a bottom portion, and an interior middle portion. The fastener-retaining passageway extends through the plate. The fastener-retaining passageway comprises an upper portion having an inwardly projecting capture lip. The capture lip has a first diameter. The fastener-retaining passageway also has a middle undercut portion that has a second diameter. The second diameter is larger than the first diameter. The plate also has at least one access channel extending through the capture lip so as to communicate with the interior middle portion of the plate. The fastener comprises a shaft, a fastener engager means extending from, disposed on or coupled with the shaft for engaging bone and a head mounted on the shaft having a radially elastic member.

Abstract: A line lock includes a body at least partially bounding a primary passageway, a secondary passageway, and a working passageway. In one embodiment at least a portion of the working passageway is disposed between the primary passageway and the secondary passageway such that a geometric line segment extending between the primary passageway and the secondary passageway intersects with working passageway. A line extends through the primary passageway, the secondary passageway and then through the working passageway such that a relative compression section of the line is formed between the primary passageway and the secondary passageway. The compression section of the line selectively biases against a portion of the line extending out of the working passageway so as to selectively lock the line to the body when the line is tensioned against the body.

Abstract: A prosthesis for the replacement of a diseased or traumatized facet of a mammalian vertebra includes a surface that articulates with another prosthetic facet or a natural facet, a portion that replaces at least a bony portion of the diseased or traumatized spine facet which is to be replaced, and an element to attach the prosthesis to the vertebra in a manner that does not require attachment to or abutment against the posterior arch. A method of installing the prosthesis includes the steps of resecting at least a portion of a facet and attaching the prosthesis in a manner that does not require attachment or abutment against the posterior arch.
