There is rare literature elaborating the complex total hip arthroplasty (THA) in patients with osteopetrosis who experienced malunion from femoral neck fracture. We have summarized the failure experience of the complex THA in osteopetrosis. Learned from the resurgery in the case reported by this paper, we recommend to highlight the initial stability of the prosthesis and not to overestimate the potency of fracture healing in the complex THA in osteopetrosis.
Keywords: Albers-schonberg disease; Osteopetrosis; complex THA; femoral neck fracture.
