An orthopedic broach is disclosed. The orthopedic broach includes a cutting tip and a broach handle. The broach handle includes a lever, a spring, and a latch. The lever is movably coupled to the handle and to an end of the spring. The latch is movably coupled to the handle and the opposite end of the spring. In use, the lever is movable from an opened position, where the latch is positioned in a released position, so that the cutting tip can be inserted into the handle, to a closed position where the latch is moved to an engaged position wherein the cutting tip is securely coupled to the latch, and thus the handle. The handle includes a spring stop to prevent the spring from further deflection to prevent the latch from moving to the released position and thus prevent decoupling of the cutting tip when excessive forces are applied.

A system for use during an orthopaedic surgical procedure includes a femoral broach, an acetabular cup component, and an acetabular alignment guide. The femoral broach includes a mounting post positioned at a superior end of an elongated body. The cup component includes a distal rim and a curved surface extending inwardly from the rim to define a cavity. The alignment guide includes a distal end configured to be coupled to the mounting post and a proximal end configured to be coupled to the distal rim. When coupled to the femoral broach, the guide instrument is sized to orient the acetabular cup component relative to the femoral broach. The acetabular cup component may be a prosthetic cup component or a trial instrument corresponding to the prosthetic cup component.

Disclosed is a tool set and an associated method for removing a prosthetic implant. Although the tools in the tool set can be used to remove a variety of different prosthetic implants, it finds particular application in the removal of femoral implants. In one embodiment, both lateral and medial tools are utilized. The lateral tool includes a generally arcuate shape with upstanding sidewalls that define an arcuate interior. The lateral tool is thus dimensioned to follow the contour of the lateral side of a femoral implant. The medial tool includes opposing side walls that define an interior opening. The opening is sized to receive the neck of the femoral implant, thereby allowing the tool to closely follow the medial bone/implant interface. In another embodiment, a J-shaped tool and an L-shaped tool are utilized to cut below an undercut of an femoral implant. The tools in the tool set can work together or individually.

A method of implant a knee prosthesis includes forming a bone void at an end of a bone, implanting a void filler in the bone void, and implanting a knee prosthesis onto the end of the bone so that a stem of the knee prosthesis is received by the void filler.

Improved instruments for modifying a shape of a proximal femur of a patient for installation of a stem of a femoral component of a prosthetic hip during hip replacement surgery, comprising a handle including an elongated shaft extending downward approximately in a z-direction, a first offset extending from a bottom of the elongated shaft approximately in a y-direction, a second offset extending from the second offset approximately in an x-direction, and a shaping member elongated downward from the second offset approximately in the z-direction. Provided is an improved femoral broach and an improved osteotome. Also provided is a method of improving a patient's positioning during hip replacement surgery by using a variable configuration mattress for positioning the patient.

Intramedullary nails, systems, and methods. The intramedullary nail may include a generally elongate body extending from a first, distal end to a second, proximal end. The distal end may include one or more openings configured to receive one or more bone anchors that extend transversely through the distal end intramedullary nail, and thereby configured to secure the distal end of the nail. The proximal end may also include one or more openings configured to receive one or more bone anchors that extend transversely through the proximal end of the intramedullary nail, and thereby configured to secure the proximal end of the nail.

A bone implant includes a bore extending entirely through the bone implant. The bone implant also includes a light source to emit light onto bone adjacent the bone implant to stimulate bone growth and/or reduce bone loss.

A cutting device is provided that includes an expandable tube having a base and a hollow interior for receiving the implant therein. The expandable tube includes cutting segments extending from the base and terminating to form a distal end of the expandable tube. At least one of the cutting segments has a cutting end with cutting teeth at the distal end of the expandable tube. Spring shaped sections are provided that extend the cutting segments. A method for removing an implant from a target bone is also provided based on the cutting device. A system for removing material directly surrounding an outer surface of an implant in an intramedullary canal of a target bone is also provided based on the cutting device and a sheath. A retractable opening is formed of leaflets at a distal end of the sheath, and a proximal end opposite the distal end.

An implantable medical device for implantation in a hip joint of a human patient is provided. The medical device comprises: at least one artificial hip joint surface adapted to replace at least the surface of at least one of the caput femur and acetabulum. At least one artificial hip joint surface comprises: a positioning hole with at least one opening in said at least one artificial hip joint surface. The hole is adapted to be placed and dimensioned such that the medical device is adapted to be fitted using a positioning shaft and at least partly surround the shaft, for positioning the at least one artificial hip joint surface in a desired position in the hip joint. The hole is adapted to be fitted using the positioning shaft, when the shaft is stabilized and placed in at least one of the femoral bone and the pelvic bone for positioning said medical device inside the hip joint.

Intramedullary nails, systems, and methods. The intramedullary nail may include a generally elongate body extending from a first, distal end to a second, proximal end. The distal end may include one or more openings configured to receive one or more bone anchors that extend transversely through the distal end intramedullary nail, and thereby configured to secure the distal end of the nail. The proximal end may also include one or more openings configured to receive one or more bone anchors that extend transversely through the proximal end of the intramedullary nail, and thereby configured to secure the proximal end of the nail. In some embodiments, the proximal end may further include a cross-locking feature, which includes a second bone anchor that interlocks with a first bone anchor, for example, for enhanced bone purchase and bony fixation.
