title: [Urinary bladder perforation caused by a loosened acetabular reinforcement ring].
abstract: Reinforcement cages are widely used for the treatment of large acetabular bone defects. We report the case of a loosened Burch-Schneider reinforcement ring causing a recurrent macrohaematuria due to a perforation of the urinary bladder. After performing several diagnostic procedures, the patient underwent interdisciplinary revision surgery. Due to the severe destruction of the acetabular bone stock and an infection of the total hip prosthesis as confirmed by fresh frozen section, the hip prosthesis was explanted. At the last follow-up the patient was free of infect-related symptoms and was able to walk with one crutch.
