Ten consecutive patients with 11 complete ulnar collateral ligament tears who had early surgical repair were evaluated at an average of 42 months' followup. The mean arc of motion at the metacarpophalangeal joint at 50.9 degrees was less than the 73.7 degrees seen in the uninjured thumbs. At the interphalangeal joint, the mean arc of motion in the injured thumb was 101.6 degrees compared with 112.6 degrees on the uninjured side. Ulnar laxity was decreased slightly compared with the contralateral thumb (14.0 degrees versus 15.3 degrees) and radial laxity was 10.3 degrees on both sides. The mean grip strength and key pinch were similar between the injured and uninjured sides: grip strength was 32.3 kg in the injured thumbs and 34.0 kg in the uninjured; key pinch was 8.1 kg in the injured thumbs and 8.8 kg in the uninjured. Good stability with slight decrease in motion was obtained in our patients.
对10例连续的、有11处尺侧副韧带完全撕裂且早期接受手术修复的患者进行了评估，平均随访42个月。掌指关节的平均活动弧度为50.9度，小于未受伤拇指的73.7度。在指间关节，受伤拇指的平均活动弧度为101.6度，而未受伤侧为112.6度。与对侧拇指相比，尺侧松弛度略有降低（分别为14.0度和15.3度），两侧桡侧松弛度均为10.3度。受伤侧与未受伤侧的平均握力和捏力相似：受伤拇指的握力为32.3千克，未受伤拇指为34.0千克；受伤拇指的捏力为8.1千克，未受伤拇指为8.8千克。我们的患者获得了良好的稳定性，但活动度略有下降。
