Isolated injuries to the dorsoradial capsule of the thumb metacarpophalangeal joint are rarely reported. We report 11 patients who had a tear in the dorsoradial capsule of the thumb metacarpophalangeal joint without an associated collateral ligament injury. Seven of the injuries were confirmed at surgical exploration and repaired by imbrication/direct repair. Six of these seven patients were able to return to unrestricted activities without requiring analgesics. The surgical patients had increased baseline metacarpophalangeal joint flexion compared to "average," which may predispose them to isolated capsular injuries.
拇指掌指关节背桡侧关节囊的孤立性损伤鲜有报道。我们报告了11例拇指掌指关节背桡侧关节囊撕裂且无相关侧副韧带损伤的患者。其中7例损伤在手术探查时得到证实，并通过重叠缝合/直接修复进行了修复。这7例患者中有6例能够恢复到不受限制的活动，无需使用镇痛药。与“平均水平”相比，接受手术的患者掌指关节的基线屈曲度增加，这可能使他们更容易发生孤立性关节囊损伤。
