Abstract：
A 17-year-old girl with bilateral ball-and-socket ankles reported left medial heel pain. Her left heel had gone into a varus position on tiptoeing, and a painful clunk had occurred when returning to normal standing. The clunk persisted after physiotherapy and treatment with an orthosis. Subtalar arthroscopy and peroneal tendoscopy showed mild diffuse synovitis of the ankle joint, especially over the posterior capsule, and a patch of inflamed and fibrotic synovium at the posterolateral corner of the subtalar joint. The clunk subsided immediately after arthroscopic synovectomy and had not recurred during 5 years of follow-up. We found no other reported cases of ankle and subtalar synovitis occurring in patients with a ball-and-socket ankle joint.
摘要：
一名17岁的双侧球窝脚踝女孩报告了左内侧足跟疼痛。她的左脚跟在tip起脚尖时出现了内翻位置，当恢复正常站立时，发生了痛苦的碰撞。在进行物理治疗和矫形器治疗后，杂音仍然存在。距下关节镜和腓骨肌腱镜检查显示踝关节轻度弥漫性滑膜炎，尤其是在后囊上，距下关节后外侧角有一块发炎和纤维化的滑膜。关节镜滑膜切除术后，结块立即消退，在5年的随访中没有复发。我们没有发现其他报道的球窝踝关节患者发生踝关节和距下滑膜炎的病例。
