Bruck syndrome: A rare case presentation with isolated lower extremity contractures and multiple postoperative peri-implant fractures

Abstract

Bruck syndrome, characterized by congenital brittle bones and multiple joint contractures, is a rare variant of osteogenesis imperfecta. Here, we report the case of a 7-year-old male patient who presented with a fractured shaft of the femur following trivial trauma. He was diagnosed case of arthrogryposis multiplex congenital with deformities involving both knees and ankle. He had a history of bilateral femoral fractures during birth. Due to the knee contracture and a narrow canal, we fixed the fracture by plating. However, the patient developed peri-implant fractures proximal to the plate. Due to the presence of multiple peri-implant fractures and joint contractures, we diagnosed the patient with Bruck’s syndrome and initiated intravenous bisphosphonate therapy. Subsequently, the patient developed one more fracture in the contralateral femur. This case signifies the importance of screening all patients with multiple congenital contractures and recurrent fractures for Bruck syndrome.
