A kit for reaming a portion of a long bone cavity for use in implanting a joint prosthesis, the reamers for cooperation with portions of an orthopaedic implant component. The kit includes a distal reamer for reaming a distal portion of the long bone and a proximal reamer for reaming a proximal portion of the long bone. The kit further includes a pilot shaft for insertion into a reamed distal portion and attachment to the proximal reamer during the reaming of the proximal portion. At least one of the distal reamer, proximal reamer, and pilot shaft is expandable, such that the at least one of the distal reamer, proximal reamer, and pilot shaft includes an expandable body adapted to adjust between a plurality of diameters.

Expandable proximal reamer

A method of milling a calcar region of the femur. The method includes using a miller assembly including a cutter and a frame. The frame has a longitudinal axis and a cutter mount for mounting the cutter at a first angle with respect to the longitudinal axis of the frame. The cutter mount extends at the first angle from the longitudinal axis of the frame and receives a portion of the cutter and maintain the received cutter oriented at the first angle during rotation. The frame includes a handle that forms a portion of a drive joint for coupling the frame to a drill. The handle is coupled to the drill and the miller assembly is inserted into the femur such that the cutter is located in the calcar region. The drill is then operated, causing the cutter to rotate and mill bone in the calcar region.

Minimally invasive bone miller apparatus

A reamer for reaming a portion of a long bone cavity for use in implanting a joint prosthesis. The reamer is used in cooperation with a portion of an orthopaedic implant component and includes an expandable body that is adapted to adjust between a plurality of diameters. A plurality of cutting edges are also included and extend outwardly from the body, the edges adapted for cooperation with bone, and the cutting edges expanding as the expandable body expands.

A miller assembly 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, and is contiguous with a pre-existing conical cavity in the bone. The miller assembly includes a cutter and a frame for carrying the cutter. The frame includes a connection portion having a longitudinal axis and a cutter mount for mounting the cutter at a first angle approximating the acute angle with respect to the longitudinal axis of the connection portion. The cutter mount extends at the first angle from the longitudinal axis of the connection portion and is configured to receive a portion of the cutter and maintain the received cutter oriented at the first angle during rotation. The frame further includes a handle configured to form a portion of a drive joint for coupling the frame to a drill, the handle having a longitudinal axis. The longitudinal axis of the handle is coincident with the longitudinal axis of the frame.

A kit for removing calcar bone from a resected face around a bone canal of a long bone prepared to receive an orthopaedic implant is provided. The kit includes a trial for insertion into the bone canal of the long bone and a fixture. The fixture has a connector for connecting the fixture to the trial and a guide for guiding the calcar reamer. The kit also includes a calcar reamer for removing calcar bone from the resected face around the bone canal of the long bone. The reamer includes a feature for cooperation with the guide of the fixture. The kit further includes an implant for insertion into the bone canal of the long bone.

Calcar planar

A bone cement mixing apparatus includes a bowl, an attachable/detachable lid, and a handle extending from the bowl. The bowl incorporates a bone cement vapor removal system that allows the extraction of bone cement vapors or fumes even after the lid has been detached from the bowl. Such extraction of vapors may be continuous. The vapor removal system is coupled to a vacuum source. The handle is ergonomically shaped and incorporates vacuum tubing that couples the bone cement vapor removal system of the bowl with the vacuum source.
