Carpometacarpal boss is a symptomatic bony prominence on the dorsal surface of the wrist at the base of the second and/or third metacarpal. Wedge excision of the carpometacarpal boss is indicated if conservative treatment fails to relieve the symptoms. Complications of wedge resection include symptomatic recurrences and carpometacarpal instability. The purpose of this Technical Note is to describe the technical details of endoscopic resection of carpometacarpal boss and synovectomy of the second carpometacarpal joint. This may reduce the amount of bone and joint resection and risk of carpometacarpal instability.
腕掌骨隆突是位于第二和/或第三掌骨基部腕背侧的有症状的骨性隆起。如果保守治疗不能缓解症状，则需行腕掌骨隆突楔形切除术。楔形切除术的并发症包括症状复发和腕掌关节不稳定。本技术说明的目的是描述腕掌骨隆突内镜下切除术及第二腕掌关节滑膜切除术的技术细节。这可能会减少骨与关节的切除量以及腕掌关节不稳定的风险。
