J Med Case Rep. 2007 Dec 6:1:174. doi: 10.1186/1752-1947-1-174.

Abstract

Introduction: Fractures of the neck of the femoral component have been reported in uncemented total hip replacements, however, to our knowledge, no fractures of the neck of a cementless forged titanium alloy femoral stem coated in the proximal third with hydroxy-apatite have been reported in the medical literature.

Case presentation: This case report describes a fracture of the neck of a cementless forged titanium alloy stem coated in the proximal third with hydroxy-apatite.

Conclusion: The neck of the femoral stem failed from fatigue probably because of a combination of factors described analytically below.
