In Denmark, approximately 7,000 hip joints are replaced by total hip arthroplasties annually. In 80% of the cases, the diagnosis is idiopathic end-stage osteoarthritis. Scientifically this is hardly acceptable. However, the last decade has witnessed a proliferative research in biomechanically important, often subtle, malformations of the hip joint which are thought to play an important role pathogenetically for the development of hip osteoarthritis and hip pain especially in younger, active patients. The common denominator for these malformations is that they cause femoro-acetabular impingement during hip flexion and internal rotation. Repetitive microtrauma damages the acetabular labrum and cartilage, and the osteoarthritic cascade is initiated in earnest. This review evaluates new research relating to this paradigm.
在丹麦，每年约有7000个髋关节通过全髋关节置换术进行置换。在80%的病例中，诊断为特发性终末期骨关节炎。从科学角度来看，这很难被接受。然而，在过去十年中，针对髋关节在生物力学上重要且往往很细微的畸形展开了大量研究，这些畸形被认为在髋关节骨关节炎和髋关节疼痛的发病机制中，尤其是在年轻、活跃的患者中，起着重要作用。这些畸形的共同特征是，它们在髋关节屈曲和内旋时会导致股骨髋臼撞击。反复的微创伤会损伤髋臼唇和软骨，骨关节炎级联反应就此真正启动。本综述评估了与这一范例相关的新研究。
