The carpal boss, an unmovable bony protuberance, is located on the dorsum of the wrist at the base of the second and third metacarpals adjacent to the capitate and trapezoid bones. This bony prominence may represent degenerative osteophyte formation and/or the presence of an os styloideum, an accessory ossification center that occurs during embryonic development. When this condition is symptomatic, patients present with complaints of pain and limitation of motion of the affected hand. The symptoms of carpal boss may result from an overlying ganglion or bursitis, an exterior tendon slipping over this bony prominence, or from osteoarthritic changes at this site. Radiographically, the view that best profiles the separate os styloideum is a lateral view utilizing 30 degrees of supination and ulnar deviation of the wrist. Once a diagnosis has been made, treatment can range from the use of nonsteroidal antiinflammatory medication and limited use of the wrist to surgical excision of the anatomic abnormality.
腕部隆突是一种不可移动的骨性突起，位于腕背侧第二和第三掌骨基部，毗邻头状骨和大多角骨。这种骨性隆起可能代表退行性骨赘形成和/或茎突骨（一种在胚胎发育过程中出现的副骨化中心）的存在。当这种情况出现症状时，患者会诉说患手疼痛和活动受限。腕部隆突的症状可能源于覆盖其上的腱鞘囊肿或滑囊炎、外部肌腱在该骨性隆起上滑动，或源于该部位的骨关节炎改变。在影像学上，能最佳显示分离的茎突骨的视图是腕关节旋前30度并尺偏的侧位片。一旦确诊，治疗方法可以从使用非甾体类抗炎药物和限制腕部活动到手术切除解剖异常。
