Femoral prosthesis fracture after hip arthroplasty revision: A Case Report and Review of Literature.

Abstract

Rationale:A solution revision prosthesis has a multilayer microporous Porocoat coating, and the availability of multiple stem body sizes ensures that the prosthesis is adapted to each patient’s anatomical structure so that there a firm attachment with the bone cortex in the middle of the femur. Therefore, the Solution prosthesis is one of the most commonly used and most effective prostheses in total hip arthroplasty worldwide.Patient concerns:We reported a case of a 54-year-old female patient with periprosthetic femoral fractures after hip arthroplasty.Diagnosis:The case was identified as type B2 prosthesis loosening according to the Vancouver classification.Interventions:We performed revision surgery on her using the Solution prosthesis. Seven months after the surgery, the patient developed a mid-femoral prosthesis fracture for no apparent reason. We performed a second revision surgery of the hip joint and allogeneic bone plate fixation.Outcomes:The patient was satisfied with the treatment.Lessons:For patients with type B2 prosthesis loosening and prosthesis fracture, hip arthroplasty revision and an allogeneic bone plate could be used to ensure more stable support.
