Abstract:
New surgical instruments and methods used to implant elements of a reverse hip prosthesis in a patient are described. The instruments are impactors which are struck with a hammer at their proximal ends after the instrument has been used to position the implant element in the patient. An acetabular cup impactor has inclination and anteversion rods which are used to position the acetabular cup optimally in the acetabulum. An acetabular ball impactor affixes the acetabular ball in the acetabular cup by means of a Morse taper. And a femoral cup impactor affixes the femoral cup in the femoral stem by means of a Morse taper.

Claim (Index 1):
A surgical instrument adapted for impacting an acetabular cup in the acetabulum of a patient wherein the acetabular cup has a stem extending from the concave surface thereof, comprising\n a handle having a proximal end and distal end, a sleeve disposed on the distal end concentric with the handle and an annular channel extending therethrough, the channel being open at the proximal and distal ends of the handle, a shaft having a proximal end and a distal end and a knob affixed to the proximal end, the shaft being slidably disposed in the channel and a collet being removably affixed to the distal end of the shaft proximate the sleeve wherein the sleeve has a tapered annular inner portion, the taper narrowing in a proximal direction, the tapered annular inner portion of the sleeve being sized to cause a distal end of the collet to contract when the collet moves into the sleeve in a proximal direction, a rotatable guide collar mounted externally on the handle and rotatable about the central axis of the handle, an inclination guide rod and an anteversion guide rod each having proximal ends affixed to the rotatable guide collar and extending outwardly therefrom at an angle relative to the central axis, and a thumb screw threaded into the rotatable guide perpendicularly or approximately perpendicularly to the central axis wherein tightening of the thumb screw prevents movement of the rotatable guide.
