Abstract：
UNASSIGNED: Modern distal biceps reconstruction techniques generally have satisfactory outcomes, but are not without complications. Posterior interosseous nerve (PIN) palsy is a rare but potentially devastating complication of bicortical metal button fixation. Recently, a unicortical, intramedullary, repair technique utilizing a suture anchor has been described. The primary aim of this study was to compare short-term functional and patient-reported outcomes and complication rates in patients receiving unicortical intramedullary repair (UR) with suture anchor against those receiving bicortical repair (BR) with metallic button. We hypothesized that UR would have equally satisfactory outcomes without the complication profile.
UNASSIGNED: Retrospective chart review was conducted for all patients undergoing operative fixation of distal biceps tendon ruptures from 2015 to 2021 at our tertiary referral center. Twenty patients received BR, and eight patients received UR. Patient demographics and surgical complications were compared. QuickDASH scores at two-month and latest in-person and telehealth postoperative visits, as well as elbow and forearm range of motion at last clinical visit, were collected and analyzed.
UNASSIGNED: Average patient age in the BR & UR cohorts were 49.3 ± 9.3 and 42.1 ± 6.2 years, respectively, with a male predominance. There was no statistical difference in patient age, sex, hand dominance, injury laterality, injury chronicity, and follow-up duration. Range of motion was comparable and excellent in both groups. Latest follow-up was 3.0 ± 0.5 years in the BR and 1.5 ± 0.4 years in the UR cohorts. QuickDASH scores improved between the two-month and latest time points in each cohort however did not differ significantly in head-to-head comparison. Complications included a case of PIN palsy, distal biceps tendon rerupture, and lateral antebrachial cutaneous nerve (LABC) neuropraxia in the BR group and two cases of LABC neuropraxia in the UR group. The number needed to treat (NNT) for the prevention of one additional case of PIN palsy using UR is 22 patients.
UNASSIGNED: Short-term functional and patient-reported outcomes in traditional BR and newly reported UR of distal biceps tendon ruptures are comparable and excellent. UR did not have higher failure rate despite follow-up periods beyond what is typically reported for tendon reruptures. In this limited retrospective cohort study, UR also did not encounter postoperative PIN palsy and had an NNT of 22 patients. In the appropriate clinical setting, this provides early evidence supporting the utilization of unicortical intramedullary suture anchor fixation of distal biceps tendon ruptures as well as associated perioperative interventions such as preoperative nerve blocks.

摘要：
未经评估：现代肱二头肌远端重建技术通常具有令人满意的结果，但并非没有并发症。骨间后神经（PIN）麻痹是双皮质金属纽扣固定的罕见但潜在的破坏性并发症。最近,一个独角兽，髓内,已经描述了利用缝合锚钉的修复技术。这项研究的主要目的是比较接受单皮质髓内修复（UR）的患者与接受金属按钮的双皮质修复（BR）的患者的短期功能和患者报告的结果和并发症发生率。我们假设UR在没有并发症的情况下也会有同样令人满意的结果。
UNASSIGNED：对2015年至2021年在我们的三级转诊中心接受肱二头肌远端肌腱断裂手术固定的所有患者进行回顾性图表回顾。20名患者接受BR，八名患者接受了UR。比较患者的人口统计学和手术并发症。QuickDASH得分在两个月和最新的面对面和远程健康术后访问，以及末次临床就诊时的肘部和前臂活动范围，进行了收集和分析。
未经评估：BR和UR队列中的患者平均年龄分别为49.3±9.3和42.1±6.2岁，分别,男性占主导地位。患者年龄无统计学差异,性别,手支配,伤害偏侧性，慢性损伤,和后续持续时间。两组的运动范围相当且出色。BR组的最新随访时间为3.0±0.5年，UR组的随访时间为1.5±0.4年。在每个队列的两个月和最新时间点之间，QuickDASH得分有所改善，但在头对头比较中没有显着差异。并发症包括一例PIN麻痹，肱二头肌远端肌腱再断裂,BR组有前臂外侧皮神经（LABC）神经失用症，UR组有2例LABC神经失用症。使用UR预防另外一例PIN麻痹所需治疗（NNT）的人数为22名患者。
UNASSIGNED：传统BR和新报告的肱二头肌远端肌腱断裂UR的短期功能和患者报告的结果相当且优异。尽管随访时间超过了通常报告的肌腱断裂时间，但UR的失败率并不高。在这项有限的回顾性队列研究中，UR也没有遇到术后PIN麻痹，并且有22例患者的NNT。在适当的临床环境中，这提供了早期证据支持使用单皮质髓内缝合锚钉固定治疗股二头肌腱远端断裂,以及相关的围手术期干预措施,如术前神经阻滞.
