PROSTHETIC FEMORAL STEM FOR USE IN HIGH IMPACT HIP REPLACEMENT

A total hip femoral prosthesis provides a shortened neck and more proximal coating level. Additionally, a means for strengthening the neck may be incorporated to increase stress transfer to the native bone. A method for reducing 5 potential impingement that results from a high neck resection level i...

Beschreibung
Zusammenfassung:	A total hip femoral prosthesis provides a shortened neck and more proximal coating level. Additionally, a means for strengthening the neck may be incorporated to increase stress transfer to the native bone. A method for reducing 5 potential impingement that results from a high neck resection level includes instrumentation for cutting chamfered surfaces into the bone surrounding the proximal end of the implant. Instrumentation and methods of creating chamfered cuts are disclosed. 130 132 134 - '120 -- 112 Fig. 1 (Background Art)
