Isolated traumatic dislocation of the carpometacarpal joint of the thumb is an uncommon injury. Left untreated, resulting mechanical instability of this joint interferes with normal function of the hand and can lead to articular degeneration of the joint. Most are amenable to closed reduction with or without supplementary pinning. We present a case of a 21 year old female patient with continual instability of the carpometacarpal joint of her right thumb, following closed reduction and pinning. Surgical stabilization was achieved by anterior oblique ligament reconstruction using a Modified Eaton- Littler's technique. At 1 year follow-up evaluation the patient was pain free with no clinico-radiological evidence of instability.
孤立性拇指腕掌关节创伤性脱位是一种罕见的损伤。若不治疗,该关节由此产生的机械性不稳定会干扰手部正常功能,并可能导致关节的关节面退变。大多数病例可通过闭合复位治疗,无论是否辅以克氏针固定。我们报告一例21岁女性患者,其右拇指腕掌关节在闭合复位及克氏针固定后仍持续存在不稳定。采用改良伊顿-利特勒技术进行前斜韧带重建,实现了手术稳定。在1年的随访评估中,患者无痛,且无临床及影像学不稳定证据。
