Synovial chondromatosis is a rare benign disorder characterized by chondroid metaplasia with multinodular proliferation of the synovial lining of a diarthroidal joint, bursa, or tendon sheath. These cartilaginous nodules may become embedded within the proliferating synovium and may extend into the surrounding soft tissues. They also can detach from the synovium, where they can calcify and may present as intra-articular loose bodies. Presence of these nodules leads to joint pain, dysfunction, and ultimately, destruction. Clinically, patients often present with a chronic monoarthropathy. In this article, we report a case of extensive synovial chondromatosis of the right shoulder and surrounding soft tissues with extensive erosion of the humeral head, discuss combined anterior and posterior surgical excision of the cartilaginous fragments, and describe insertion of an osteoarticular allograft to repair the humeral head defect and secondary anterior glenohumeral joint instability.
滑膜软骨瘤病是一种罕见的良性疾病，其特征为关节软骨化生，伴有滑膜关节、滑囊或腱鞘滑膜衬里的多结节性增生。这些软骨结节可能嵌入增生的滑膜内，并可延伸至周围软组织。它们也可从滑膜上脱落，在那里发生钙化，并可能表现为关节内游离体。这些结节的存在会导致关节疼痛、功能障碍，最终导致关节破坏。临床上，患者常表现为慢性单关节病。在本文中，我们报告一例右肩部及周围软组织广泛滑膜软骨瘤病伴肱骨头广泛侵蚀的病例，讨论软骨碎片的前后联合手术切除，并描述植入骨关节异体移植物修复肱骨头缺损及继发性肩肱关节前向不稳的情况。
