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.
