A reamer for reaming a proximal portion of a cavity for use in implanting a joint prosthesis is provided. The reamer is used for cooperation with a proximal portion of an orthopaedic implant component. The reamer includes a body defining a cavity formed therein for receiving at least a portion of the orthopaedic implant component. The reamer also includes a plurality of cutting edges extending outwardly from the body. The edges are adapted for cooperation with bone. The reamer also includes a stem extending from an end of the body.

A broaching system is disclosed for creating a cavity in a bone. The cavity has a cross section which has a generally triangular profile having a first side generally parallel with an axis of the bone and a second side forming an acute angle with the first side. The cavity is contiguous with a pre-existing conical cavity in the bone. The apparatus comprises as shaft and a broach. The shaft has a longitudinal axis. The broach is mounted to the shaft and has a first cutting side mounted at the acute angle relative to the longitudinal axis of the shaft. The first cutting side is formed to include teeth. The shaft and broach are configured so that when the longitudinal axis of the shaft is advanced into the bone along the axis of the bone, the teeth of the broach form the triangular cavity. A method for cutting a triangular cavity in bone is also described. The method comprises a providing a shaft step, an incising step and a cutting step. The provided shaft is configured to be movable relative to the bone to be prepared and includes a broach coupled thereto to dispose a cutting surface of the broach at an acute angle relative to the shaft. The shaft and broach have a width defined by the distance between the shaft and the outer most portion of the cutting surface. The incising step includes incising the patient adjacent the bone to be prepared to form an incision having a length approximating the width of shaft and broach. The cutting step includes cutting the cavity by driving the broach by moving the shaft relative to the bone.

A prosthetic implant for securing to bone to form an articulating joint is provided. The implant is prepared by a process which includes the steps of preparing a porous surface on a component to form a prosthetic implant, placing the prosthetic implant including the porous surface in a fixture closely conforming to the porous surface of the implant and having an inlet and an opposed outlet, and directing a biological compound including stem cells into the inlet, through the porous surface of the implant and out of the outlet to form a prosthetic implant having a porous surface coated with a portion of the biological compound.

A patient-specific registration jig for registering an orthopaedic surgical instrument with a bony anatomy of a patient includes a head and an adaptor coupled to the head. The head includes a patient-specific contact surface configured to contact a portion of the patient's bony anatomy such that the head can be coupled to the patient's bony anatomy in a unique position. The adaptor includes an elongated shank having a first end coupled to the head and a second end and an adaptor end attached to the second end of the elongated shank. The adaptor end is configured to be received by a clutch of the orthopaedic surgical instrument. A method for registering the orthopaedic surgical instrument using the patient-specific registration jig is also disclosed.
