Abstract

Purpose: Scapular Notching (SN) is one of the most common postoperative complications for a patient after Reverse Total Shoulder Arthroplasty (RTSA). Despite employing various strategies to mitigate SN risk, the overall incidence remains far from zero. This article introduces a new risk factor, the scapulo-humeral angle (SHA), as a key element influencing the risk for SN.

Methods: A retrospective analysis was conducted on all patients who underwent RTSA for rotator cuff arthropathy at the study centre. The preoperative SHA was measured, and the presence of SN was investigated and graded using the Nerot classification at the latest follow-up.

Results: 42 patients were included. 12 presented SN (incidence 28.5%). A statistically significant Pearson coefficient correlation between pre-operative SHA and the incidence of SN was observed (r= -0.6954; 95% C.I. -0,8250 to -0,4963; p < 0.0001). A statistically significant Pearson coefficient correlation was also found between the degree of SN and the pre-operative SHA (r= -0,7045; 95% C.I. -0,8306 to -0,5096; P value (two-tailed) < 0,0001, alpha 0.05).

Conclusions: The primary finding is a statistically significant correlation between a reduced preoperative SHA and an increased incidence of postoperative SN. The secondary finding is that a smaller preoperative SHA is associated with a more severe degree of SN A SHA cut-off of 50° distinguished patients at high risk of SN from those at low risk. All patients with an SHA below 50° developed SN (10/10), whereas only 6.25% of patients with an SHA exceeding 50° experienced SN (2/32).

肩胛骨与肱骨的夹角减小会导致反向全肩关节置换术中出现肩胛骨切迹。

目的：肩胛骨切迹（SN）是反向全肩关节置换术（RTSA）患者最常见的术后并发症之一。尽管采用了各种策略来降低肩胛骨切迹的风险，但总体发生率仍远未达到零。本文介绍了一个新的风险因素--肩胛肱骨角（SHA），它是影响SN风险的关键因素：方法：研究中心对所有因肩袖关节病接受 RTSA 的患者进行了回顾性分析。结果：共纳入42名患者：结果：共纳入 42 名患者。结果：共纳入 42 例患者，其中 12 例出现 SN（发生率为 28.5%）。术前 SHA 与 SN 发生率之间的皮尔逊系数相关性具有统计学意义（r= -0.6954；95% C.I.-0.8250~-0.4963；p 结论：该研究的主要发现是，术前 SHA 与 SN 的发生率之间存在统计学意义上的相关性（r= -0.6954；95% C.I.-0.8250~-0.4963）：主要发现是术前 SHA 减少与术后 SN 发生率增加之间存在统计学意义上的显著相关性。其次，术前 SHA 值越小，SN 的程度越严重。所有 SHA 低于 50° 的患者都出现了 SN（10/10），而 SHA 超过 50° 的患者中只有 6.25% 出现 SN（2/32）。

期刊介绍： International Orthopaedics, the Official Journal of the Société Internationale de Chirurgie Orthopédique et de Traumatologie (SICOT) , publishes original papers from all over the world. The articles deal with clinical orthopaedic surgery or basic research directly connected with orthopaedic surgery. International Orthopaedics will also link all the members of SICOT by means of an insert that will be concerned with SICOT matters. Finally, it is expected that news and information regarding all aspects of orthopaedic surgery, including meetings, panels, instructional courses, etc. will be brought to the attention of the readers. Manuscripts submitted for publication must contain a statement to the effect that all human studies have been approved by the appropriate ethics committee and have therefore been performed in accordance with the ethical standards laid down in the 1964 Declaration of Helsinki. It should also be stated clearly in the text that all persons gave their informed consent prior to their inclusion in the study. Details that might disclose the identity of the subjects under study should be omitted. Reports of animal experiments must state that the "Principles of laboratory animal care" (NIH publication No. 85-23, revised 1985) were followed, as well as specific national laws (e.g. the current version of the German Law on the Protection of Animals) where applicable. The editors reserve the right to reject manuscripts that do not comply with the above-mentioned requirements. The author will be held responsible for false statements or for failure to fulfil the above-mentioned requirements.
