Abstract：
OBJECTIVE: The purpose of this study was to compare clinical and radiologic outcomes of biological ligament reconstruction (BLR) versus nonbiological ligament reconstruction (NBLR) for chronic injuries involving the ulnar collateral ligament of the thumb\'s metacarpophalangeal joint.
METHODS: Forty-two patients who underwent static BLR (n = 24) or NBLR (n = 18) were included in this retrospective analysis. Preoperative, postoperative, and contralateral thumb measurements (clinical evaluation, radiographs, and subjective outcome questionnaires) were compared over a mean of 38 months of follow-up.
RESULTS: Average postoperative thumb metacarpophalangeal and interphalangeal joint ranges of motion were 2° to 54° and 0 to 71°, respectively, for BLR and 0° to 58° and 0° to 71°, respectively, for NBLR. Average grip and pinch strengths, relative to the unaffected hand, were 102% and 84% versus 103% and 89%, respectively. All patients demonstrated stability with a firm end point, compared with the unaffected thumb. The average Quick Disabilities of the Arm, Shoulder, and Hand score among all patients was 12 for the disability/symptom module, 0 for the sports module, and 17 for the work module. Stiffness was reported among four patients, and no patient sustained wound-related issues or other complications.
CONCLUSIONS: Nonbiological ligament reconstruction of the thumb ulnar collateral ligament generates short-term outcomes comparable with those of BLR, potentially allowing for expedited recovery and rehabilitation.
METHODS: Therapeutic IV.

摘要：
目的：本研究的目的是比较生物韧带重建（BLR）和非生物韧带重建（NBLR）治疗拇指掌指关节尺侧副韧带慢性损伤的临床和放射学结果。
方法：本回顾性分析纳入42例接受静态BLR（n=24）或NBLR（n=18）的患者。术前,术后,和对侧拇指测量(临床评估，射线照片,和主观结果问卷）在平均38个月的随访中进行比较。
结果：术后拇指掌指关节和指间关节的平均活动范围为2°至54°和0°至71°，分别,对于BLR和0°至58°和0°至71°，分别,对于NBLR。平均抓地力和捏合强度，相对于未受影响的手，分别为102%和84%，103%和89%，分别。所有患者均表现出稳定，终点明确，与未受影响的拇指相比。手臂的平均快速残疾，肩膀,所有患者的残疾/症状模块的手评分为12，0为运动模块，17为工作模块。据报道，四名患者僵硬，并且没有患者持续的伤口相关问题或其他并发症。
结论：拇指尺侧副韧带的非生物韧带重建可产生与BLR相当的短期结果，可能允许加快恢复和康复。
方法：治疗IV。
