Abstract

We report a case of stem fracture of a collarless, polished, double-taper cemented stainless steel femoral prosthesis. Scanning electron microscopy showed fatigue striations, indicating failure by fatigue. This case study highlights that stem fracture can still occur with modern implants. Size 0 CPT stem should be avoided in patients with high body mass index. To our knowledge this is the first case report of a CPT stem fracture used for primary total hip replacement.
