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.
骨硬化症是一种遗传性疾病，其特征是骨密度增加和骨质脆弱。骨硬化症患者常在40岁以后出现退行性改变。如果继发性骨关节炎的临床表现严重，手术干预是主要的治疗选择。一名患有常染色体显性骨硬化症和进行性单侧髋关节骨关节炎的44岁男性需要进行全髋关节置换术。然而，该手术存在一些技术挑战，包括建立股骨髓腔以及术后发生温哥华B2型假体周围股骨骨折。为了积累处理类似病例的经验，我们在此介绍针对这些问题的技术解决方案。
