Osteopetrosis is an inherited disorder characterized by increased bone density and brittle bone quality.Degenerative changes often occur after the age of 40 in patients with osteopetrosis.Operative intervention is the primary treatment option if the clinical manifestation of secondary osteoarthritis is severe.A 44-year-old male suffering autosomal dominant osteopetrosis and progressive unilateral hip osteoarthritis required a total hip arthroplasty.However,there were several technical challenges associated with this procedure including creating a femoral medullary canal and developing a Vancouver type B2 periprosthetic femoral fracture postoperatively.To afford some experience for the management of similar cases,we here present our technical solutions to these problems.
