Abstract

Introduction: Total hip arthroplasty (THA) after proximal femoral fixation is a challenging procedure due to possible hardware-related complications.
Case presentation: A 78-year-old female with hip osteoarthritis had a proximal femoral osteotomy fixed using a blade plate in the same femur 41 years ago. A two-step approach was planned. After a challenging hardware removal, an iatrogenic subtrochanteric fracture below the degenerated hip occurred after three months. THA with a tapered long stem was successfully performed with no need for additional osteosynthesis, and good results were seen two years later.
Discussion: THAs in subtrochanteric fractures are technically demanding but feasible in selected cases. Hardware removal before THA implantation may carry important risks, and the surgical team should be prepared to perform arthroplasty in case of complications.
Conclusion: THA in a subtrochanteric fracture below hip osteoarthritis is a feasible option in selected cases.
