A prosthetic system that includes a prosthetic implant and a support structure secured to an inner surface of the cavity in the end of the bone is disclosed. The support structure defines a channel that extends through the length of the support structure. The prosthetic implant is received in the channel, and a portion of the prosthetic implant is secured to an inner surface of the channel by an adhesive. The stem of the prosthesis beyond the channel may be cemented or uncemented. The support structure may have an approximately funnel shape. The support structure may be a hollow porous cylindrical sleeve. The support structure may comprise a pair of partially hemispherical components arranged in spaced apart relationship thereby defining a channel between the pair of components. The support structure may comprise a plurality of pedestals secured to the inner surface of the cavity of the bone.

Tissue spacer implants, surgical distraction instruments, surgical insertion tools, coupling devices, surgical kits, surgical methods for distraction, and methods for coupling bodies are disclosed. The tissue spacer implants include a first end member, a second end member, and an intermediate spacer member having a coupling mechanism adapted to couple the first end member with the intermediate spacer member and to couple the second end member with the intermediate spacer member. The surgical instruments may be used for inserting these implants and include a first elongated member, a second elongated member, a distraction mechanism, and an actuator. The coupling devices may be used to couple the components of the implants.

The invention features a glenoid (shoulder socket) implant prosthesis, a humeral implant prosthesis, devices for implanting glenoid and humeral implant prostheses, and less invasive methods of their use for the treatment of an injured or damaged shoulder.

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.

This invention provides a device and treatment method for replacing the hip (in either a hemiarthroplasty or total hip arthroplasty), which protects the remainder of the femur from fracture. Such a device is highly applicable to the treatment of patients with current or impending fractures of the femur, particularly those with metastatic bone cancer, where there is concern for current or future metastatic disease of the femoral neck or head, which would necessitate hip replacement. The implant consists of a two-piece arrangement with a separate femoral component and a securing, intermedullary rod/nail that is received in a locking arrangement by a longitudinal fenestration of the femoral component.

Disclosed is a resection guide, a trial knee joint implant, and a surgical instrument for knee arthroplasty. The resection guide, the trial knee joint implant, and the surgical instrument enable implantation of an implant that provides improved vertical fixing force and initial fixing force as compared with an existing cementless or uncemented implant.

A knee joint implant is capable of resolving issues of conventional cementless or uncemented implants. The knee joint implant improves fixing force of the implant in a vertical direction and provides improved initial fixation for the implant.
