Neck fracture of a cementless forged titanium alloy femoral stem following total hip arthroplasty: a case report and review of the literature.
BACKGROUND
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.


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


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