A user may move the burr mounting arm about the cutting axis so that the arm follows along the cam surface of the housing.

Abstract: A trial implant component for use in a surgical procedure for replacement of a joint between a long bone and another bone, comprises a metaphyseal part which can be located so that it extends into a cavity at the resected face of the long bone in contact with the internal wall of the cavity in the metaphyseal region, and a disk which has an essentially flat shape and which can be fitted to the metaphyseal part to provide a gauge as to the appropriate size of a head part which is to be selected according to the location of the axis of the bone relative to the edge of the resected bone.

Abstract: A prosthesis assembly for use with a scapula is disclosed. The prosthesis assembly includes a glenoid bearing support and a bearing. The glenoid bearing support includes a glenoid vault-occupying portion configured to occupy at least a portion of a glenoid vault of the scapula, the glenoid-vault occupying portion having a first coupling component. The glenoid bearing support further includes a glenoid rim replacement portion attached to the glenoid vault-occupying portion. The bearing defines a bearing surface and has a second coupling component configured to cooperate with the first coupling component to couple the bearing to the glenoid vault-occupying portion.
