Background:

Both beach-chair and lateral decubitus patient positioning are often utilized for shoulder arthroscopy, with each offering its unique advantages and disadvantages. The surgical position is often selected according to each surgeon's preference, with no clear superiority of one position over the other.

Purpose/Hypothesis:

The purpose was to compare clinical and patient-reported outcomes between patients who underwent arthroscopic posterior labral repair in the beach-chair versus the lateral decubitus position. We hypothesized that patient positioning would not affect clinical and patient-reported outcomes.

Study Design:

Cohort study; Level of evidence, 3.

Methods:

A list of all patients diagnosed with the Current Procedural Terminology codes 29806 and 29807 between 2015 and 2019 was obtained from the medical records. Patients were only included if arthroscopic posterior labral repair with or without concomitant superior labral anterior to posterior repair was confirmed. Data collected for eligible patients included the number of anchors used, perioperative and postoperative complications, redislocations, subjective instability, reoperation, and revision. Patients were also contacted to complete several patient-reported outcome surveys. Preoperative data, perioperative data, and postoperative outcomes were compared between patients who underwent surgery in the beach-chair versus lateral decubitus position.

Results:

Overall, 126 patients were included—69 patients underwent surgery in the lateral decubitus position and 57 in the beach-chair position—with a mean follow-up of 2.6 ± 1.7 years. There were no significant pre- or perioperative differences between groups. Rates of postoperative dislocations, subjective instability, reoperations, revisions, all complications, and return to sports rates also did not differ between groups (all, P > .05). Finally, there was no difference between groups regarding postoperative pain, function, and subjective instability scores (all, P > .05). Results of the multivariate regression analysis showed that increased age was a weak independent risk factor for subjective recurrent posterior shoulder instability (odds ratio, 1.04; P = .036).

Conclusion:

Surgical positioning for arthroscopic posterior shoulder labral repair did not affect postoperative clinical and patient-reported outcomes. Both beach-chair and lateral decubitus position provided good outcomes for posterior shoulder labral repair, with an overall recurrence rate of 8.7%. Increased age was a weak independent risk factor for subjective recurrent instability.

用于关节镜后肩盂唇修复的沙滩椅与侧卧位定位：临床和患者报告结果的回顾性比较

背景：

沙滩椅和侧卧患者体位通常用于肩关节镜检查，各有其独特的优点和缺点。手术位置通常根据每个外科医生的偏好来选择，没有一个位置优于另一个位置。

目的/假设：

目的是比较在沙滩椅上接受关节镜后盂唇修复与侧卧位的患者之间的临床和患者报告的结果。我们假设患者体位不会影响临床和患者报告的结果。

学习规划：

队列研究；证据水平，3。

方法：

从医疗记录中获得了 2015 年至 2019 年期间被诊断为当前程序术语代码 29806 和 29807 的所有患者的名单。仅当关节镜后盂唇修复伴或不伴上盂唇前后修复得到确认时才纳入患者。为符合条件的患者收集的数据包括使用的锚钉数量、围手术期和术后并发症、再脱位、主观不稳定性、再次手术和翻修。还联系了患者以完成几项患者报告的结果调查。比较了在沙滩椅上与侧卧位接受手术的患者的术前数据、围手术期数据和术后结果。

结果：

总体而言，纳入了 126 名患者——其中 69 名患者接受了侧卧位手术，57 名患者接受了沙滩椅位手术——平均随访时间为 2.6 ± 1.7 年。两组之间没有显着的术前或围手术期差异。术后脱位率、主观不稳、再手术率、翻修率、所有并发症发生率和恢复运动率在各组之间也没有差异（所有，P > .05）。最后，两组在术后疼痛、功能和主观不稳定性评分方面没有差异（所有，P > .05）。多元回归分析的结果表明，年龄增加是主观复发性肩后部不稳定的弱独立危险因素（优势比，1.04；P = .036）。

结论：

关节镜后肩盂唇修复的手术定位不影响术后临床和患者报告的结果。沙滩椅和侧卧位都为后肩盂唇修复提供了良好的结果，总体复发率为 8.7%。年龄增加是主观反复不稳定的弱独立危险因素。
