摘要:

颞下颌关节(temporomandibular joint, TMJ)创伤性骨关节炎(post-traumatic osteoarthritis, PTOA)是由于创伤导致的关节软骨退行性变,临床表现为持续性关节疼痛并可放射到颈肩部肌肉、关节弹响或摩擦音、张口受限、咀嚼无力等。病理表现为关节软骨丧失、骨赘形成和软骨下骨硬化。目前的治疗主要是药物缓解症状和晚期病变的人工关节置换,尚缺乏在病变早期有效中止甚至逆转病变进展的药物治疗,为此有必要理解其发病机制,寻找有效的药物靶点。本文就近年来TMJ PTOA及其发病机制的研究进展做一综述。

Abstract:

Abstract: Temporomandibular joint (TMJ) post-traumatic osteoarthritis (PTOA) is defined as progressive articular cartilage degeneration caused by trauma. Clinical manifestations are persistent pain which could radiate to neck and shoulder muscles, joint clicking or crepitus, limitation of mouth opening and weakness of chewing. Pathology shows loss of articular cartilage, osteophyte formation and subchondral bone sclerosis. The current treatment is mainly drugs administration to relieve pain and artificial joint replacement for advanced lesions. There is still a lack of effective medication to stop or even reverse the progression in the early stage of PTOA. In order to look for effective targets it is necessary to understand the pathogenesis. TMJ PTOA and its pathogenesis research progress were reviewed in this article.

Key words: temporomandibular joint, post-traumatic osteoarthritis, pathogenesis
