Vorrichtung zum Positionieren einer Prothese

摘要

Apparatus for positioning a prosthesis (60) in a bone includes a body (10), first and second clamps, a depth gauge (30) and a guide (40). The first clamp (20) is coupled to the body (10). The depth gauge (30) is coupled to the body (10) and is movable relative thereto generally perpendicular to the shaft of the bone. The second clamp (50) can be selectively engaged with and disengaged from the depth gauge (30). The second clamp (50) is movable with the depth gauge (30) and is also moveable in a direction generally parallel to the axis of the bone. The guide (40) is used to determine the proper rotational orientation of the apparatus. The first clamp (20) is then secured to the bone. The second clamp (50) is secured to a trial prosthesis and is engaged with the depth gauge (30) as the trial is inserted into the bone. When the proper insertion depth is reached, the second clamp is secured to the depth gauge. The joint is then reduced and the range of motion checked. The depth and rotational orientation can be adjusted as needed. The second clamp (50) is released from the trial, the trial is removed and the prosthesis (60) is inserted in the bone and secured to the second clamp.
