A swelling and ache on the dorsum of the wrist in relation to the base of the 3rd metacarpal bone may indicate a bony lesion or an enlarged styloid process. It may also be due to an old fracture of the process or an accessory ossicle (os styloideum). Approximately half the 14 patients (15 wrists) had a history of an injury, usually a hit with the fist. Recurrent occupational strain may also produce symptoms at this site. Excision of the metacarpal base with the adjacent capitate or trapezoid, and repair of the periosteum and extensor tendon, will remove the lump and usually relieve symptoms.
手腕背侧与第三掌骨基部相关处的肿胀和疼痛可能表明存在骨病变或茎突增大。也可能是由于该部位的陈旧性骨折或副骨（茎突骨）所致。14例患者（15只手腕）中约一半有受伤史，通常是被拳头击中。反复的职业劳损也可能在该部位产生症状。切除掌骨基部及相邻的头状骨或梯形骨，并修复骨膜和伸肌腱，将消除肿块并通常缓解症状。
