Hypertrophic peroneal tubercle (HPT) is an overgrowth of the peroneal tubercle located on the lateral aspect of the hindfoot, which could cause tenosynovitis of the peroneus longus tendon. Os peroneum (OP) is an accessory ossicle that exists in the peroneus longus tendon at the lateral aspect of the calcaneocuboid joint. Both HPT and OP can cause lateral foot pain and occasionally require surgical treatment. We encountered a case of lateral foot pain of HPT coexisting with OP. Careful preoperative magnetic resonance imaging, dynamic ultrasonographic image, and block injection suggested an impingement of HPT and OP as a cause of lateral foot pain. Surgical resection of HPT, while retaining OP, successfully achieved pain relief in the patient. To the best of our knowledge, this is the first report presenting a case of HPT coexisting with OP successfully treated without OP resection.
肥大性腓骨结节（HPT）是位于后足外侧的腓骨结节过度生长，可导致腓骨长肌腱腱鞘炎。腓籽骨（OP）是位于跟骰关节外侧的腓骨长肌腱内的副骨。HPT和OP均可引起足外侧疼痛，偶尔需要手术治疗。我们遇到一例HPT与OP并存导致足外侧疼痛的病例。仔细的术前磁共振成像、动态超声图像和阻滞注射提示HPT和OP的撞击是足外侧疼痛的原因。手术切除HPT，保留OP，成功缓解了患者的疼痛。据我们所知，这是首例报告HPT与OP并存且未切除OP而成功治疗的病例。
