A bone plate includes first and second ends opposed along a longitudinal axis oriented along a longitudinal direction, first and second sides opposed along a lateral direction, and a bone-facing surface and an outer surface opposed along a transverse direction. The plate defines a first hole and a second hole arrangement extending from the outer to the bone-facing surface. The second hole arrangement is distal of the first hole, which is configured to receive a first fixation member, and the second hole arrangement is configured to receive at least one second fixation member for affixing with underlying bone. The plate is pivotable along an angulation range about the first hole. The second hole arrangement laterally crosses the longitudinal axis, defines the angulation range, and allows the at least one second fixation member to substantially secure the plate to the underlying bone at any angulation within the angulation range.

The improved endoprosthetic device surface treatment encourages soft tissue attachment thereto. A porous mesh surface treatment creates on an outer surface of the endoprosthetic device a three-dimensional surface structure similar to cancellous bone. Suture attachment features are provided at various locations around the treated surface structure to initially affix a vascularized soft tissue to the treated surface. As the patient heals the soft tissue grows and infiltrates the porous mesh surface to achieve an attachment strength substantially equal to the surrounding tissue.

The invention relates to a prosthesis for implantation into a long bone during joint arthroplasty, particularly Total Shoulder Arthoplasty and Total Hip Arthroplasty, and a method for use of the implant.

A system for implanting a prosthetic device with an opening into a bone includes a plug that is removably received within the opening of the prosthetic device. The system also includes a bone removal tool that advances into the bone from outside the bone and that removes a portion of the bone while advancing into the bone to reveal the plug. The bone removal tool includes a plug engaging portion that engages with the plug. The bone removal tool at least partially removes the plug from the opening of the prosthetic device while engaged with the plug. Moreover, the system includes an alignment system that detects whether the bone removal tool and the plug are substantially axially aligned.

A blade-like stem of a hip joint prosthesis for anchoring in the femur, including a prosthesis neck portion and a femur-anchoring portion extending therefrom and having a proximal end and a distal end, the femur-anchoring portion including a proximal arcuate portion extending from a location adjacent the proximal end and having a radius of curvature that changes in a distal-to-proximal direction, and the femur-anchoring portion further including a distal tapered portion extending from the proximal arcuate portion toward the distal end.

A method of assembling a mobile bearing acetabular component of a prosthetic hip joint is disclosed. The method includes mounting an acetabular cup insert to an acetabular cup. The method includes concurrently repositioning the acetabular cup insert deeper into an interior of the acetabular cup and repositioning the acetabular cup insert outside of an outline of the acetabular cup.

A medical implant system is described for inhibiting infection associated with a joint prosthesis implant. An inventive system includes an implant body made of a biocompatible material which has a metal component disposed on an external surface of the implant body. A current is allowed to flow to the metal component, stimulating release of metal ions toxic to microbes, such as bacteria, protozoa, fungi, and viruses. One detailed system is completely surgically implantable in the patient such that no part of the system is external to the patient while the system is in use. In addition, externally controlled devices are provided which allow for modulation of implanted components.

An orthopaedic prosthesis for use in a hip replacement surgery. The orthopaedic prosthesis includes an elongated stem component that has a proximal body, a neck extending superiorly and medially from the proximal body and a tapered stem extending inferiorly from the proximal body. An anchor is positioned on the neck and is configured to be engaged by a surgical instrument. A system for use in assembling the orthopaedic prosthesis and a method of assembly are also disclosed.

The invention relates to a hip joint prosthesis comprising a shaft-like section that can be inserted into a femur, and a proximally arranged end cap assembly which closes a hollow space of the hip joint prosthesis. According to the invention the end cap assembly carries a coil assembly that is connected to a first electrode with a first pole and to a second electrode with a second pole. The first and the second electrodes enclose surfaces of the hip joint prosthesis, and in a state in which the end cap assembly closes the hollow space of the hip joint prosthesis, the coil assembly is predominantly arranged in the hollow space.
