No clinical studies to date have analyzed the critical shoulder angle (CSA) following anterior acromioplasty. Our study's main objective was to measure the change in the CSA after acromioplasty.
Ninety patients were included in this retrospective series. The CSA and the type of acromion were evaluated before and after surgery.
The average CSA for patients before surgery was 35.9° (± 3.7, 26.2, 44.2) and 33° after the acromioplasty (± 3.5, 24.8, 41.4). The decrease was significant and 2.9° on average (± 2.2, - 2.2, 11.9, p = 0.000). Preoperatively, 58% of patients had a CSA ≥ 35° (n = 52) and 24% postoperatively (n = 22, p = 0.000).
Standardized anterior acromioplasty allows for a significant decrease in the CSA without lateral resection of the acromion. This study confirms the tight link between the CSA and the anterior acromion as well as the interest of this angle to quantify acromioplasty whether anterior or lateral.
Level IV, Case Series, Retrospective design.
目前尚无临床研究分析肩峰前切除术（anterior acromioplasty）后关键肩角（critical shoulder angle，CSA）的变化。我们的研究主要目的是测量肩峰前切除术后 CSA 的变化。
本回顾性系列研究纳入了 90 例患者。手术前后评估 CSA 和肩峰类型。
术前患者 CSA 的平均值为 35.9°（±3.7，26.2，44.2），肩峰前切除术后为 33°（±3.5，24.8，41.4）。下降显著，平均为 2.9°（±2.2，-2.2，11.9，p=0.000）。术前 58%的患者 CSA≥35°（n=52），术后为 24%（n=22，p=0.000）。
标准的肩峰前切除术可显著降低 CSA，无需进行肩峰外侧切除。该研究证实 CSA 与肩峰前侧之间存在紧密联系，无论采用前侧还是外侧入路，该角度均有助于定量评估肩峰成形术。
