Abstract：
A 77-year-old woman presented with a mucous cyst on the lateral aspect of the interphalangeal joint of the first toe caused by contact pressure with the second toe from hallux valgus. She complained of discomfort and discharge from the left first toe for approximately 4 months. Physical examination showed the second toe pressing strongly against the first toe due to hallux valgus and discharge from the skin on the lateral aspect of the interphalangeal joint of the first toe. Magnetic resonance imaging showed a cystic lesion at the same level. The patient underwent a modified scarf osteotomy of the first metatarsal for hallux valgus to resolve the contact pressure between the toes-considered the cause of the mucous cyst-and resection of mucous cyst. Forefoot weight bearing was allowed 6 weeks after surgery. As of 1 year after surgery, she has had no recurrence of the cyst. The score on the Japanese Society for Surgery of the Foot hallux metatarsophalangeal-interphalangeal scale improved from 59/100 points to 92/100. This outcome suggests that hallux valgus correction should be considered when a mucous cyst is associated with contact pressure due to a hallux valgus deformity. To the best of our knowledge, there are no previous reports of a mucous cyst caused by contact pressure between the first toe and second toe due to hallux valgus.
摘要：
一名77岁的妇女，由于与外翻产生的第二脚趾的接触压力，在第一脚趾的指间关节的外侧出现粘液囊肿。她抱怨左第一脚趾不适和放电约4个月。体格检查显示，由于外翻和第一脚趾指间关节外侧的皮肤放电，第二脚趾强烈压在第一脚趾上。磁共振成像显示相同水平的囊性病变。该患者接受了第一meta骨改良的围巾截骨术，以解决脚趾之间的接触压力-认为是粘液囊肿的原因-并切除了粘液囊肿。手术后6周允许前足负重。手术后1年,她没有囊肿复发。日本足趾趾趾-指间外科学会评分从59/100分提高到92/100分。此结果表明，当黏液囊肿与外翻畸形引起的接触压力相关时，应考虑进行外翻矫正。据我们所知,以前没有报告说，由于外翻，第一脚趾和第二脚趾之间的接触压力引起的粘液囊肿。
