“…In the literature, there are many studies evaluating the relationship between morphological features of acromion and RCT. 5 - 9 Oh et al determined that the thicker acromion was related to the RCT, and the average acromion thickness was 8 mm. 5 Computed tomography (CT), magnetic resonance imaging (MRI), and radiography can be used to measure acromial thickness (AT).…”

Objective: This study aimed to determine the effect of reduced acromiohumeral distance (AHD) and increased acromial thickness (AT) on the risk of rotator cuff tear (RCT). Methods: Patients aged 25-70 were included in this retrospective study. Patients who were operated on for RCT between January 2019 and December 2021 were included in group 1, and patients who applied to the outpatient clinic in the same period with a complaint of shoulder pain and no problem on magnetic resonance imaging (MRI) were included in group 2. Three researchers performed AHD and AT measurements on the same true anteroposterior (AP) shoulder radiographs. The second measurement was performed 1 month later when, the first measurements were completed. Results: Radiographs of 284 patients in group 1 and 234 patients in group 2 were evaluated. In group 1, the mean AHD measurement was 8.25 ± 1.73 mm, and the AT measurement was 8.58 ± 1.06 mm. In group 2, the mean AHD measurement was 10.25 ± 1.4 mm, and the AT measurement was 8.35 ± 0.92 mm. A significant relationship was determined between the RCT and the AHD ( P < .001). Also, RCT and AT have a significant relationship ( P < .001). The authors determined that the risk of RCT increased 3.45 times when patients with AHD 6-10 mm were compared with patients with AHD >10 mm. In addition, all patients with AHD < 6mm had RCT, and the risk of RCT increased 1.42 times when patients with AT > 8 mm were compared with patients with AT < 8 mm. Conclusion: Acromiohumeral distance and AT measurements are practical, inexpensive, and valuable in evaluating RCT. Decreased AHD and increased AT increase the risk of RCT. Level of Evidence: Level III, Diagnostic Study.

“…However, no previous study classified the location or shape of rotator cuff injury caused by sub‐acromial impingement. During arthroscopic surgery it is evident that the rotator cuff injuries caused by sub‐acromial impingement do not just occur in a fixed location; in contrast, the rotator cuff injury can manifest as injury to the anterior, middle and posterior aspects of rotator cuff 10 . Furthermore, the location of impingement mostly occurs in the lateral rotator cuff although this can occasionally occur in a medial position (close to the tendon‐muscle interface) 11 .…”

ObjectivesRotator cuff injury caused by subacromial impingement presents different morphologies. This study aims to investigate the correlation between various shoulder anatomical indexes on X‐ray with subacromial impingement and morphology of rotator cuff tears to facilitate surgical management.MethodThis retrospective study was carried out between January 2020 and May 2022. Patients who were diagnosed as sub‐acromial impingement associated with rotator cuff tears (without tendon retraction) and received arthroscopic surgery were enrolled in this study. The radiographic indexes of acromial slope (AS), acromial tilt (AT), lateral acromial angle (LAA), acromial Index (AI), and sub‐acromial distance (SAD) were measured on preoperative true AP view and outlet view. The location of rotator cuff tear (anterior, middle, posterior, medial, and lateral) and morphology of tear (horizontal, longitudinal, L‐shaped, and irregular shaped) were evaluated by arthroscopy. Groups were set up due to different tear location and tear morphologies, by comparing the various radiographic indices between each group (one‐way analysis of variance and t‐test), the correlation between radiographic indices and tear characteristics was investigated.ResultsWe analyzed 92 shoulders from 92 patients with a mean age of 57.23 ± 8.45 years. The AS in anterior tear group (29.32 ± 6.91°) was significantly larger than that in middle tear group (18.41 ± 6.13°) (p = 0.000) and posterior tear group (24.01 ± 7.69°) (p = 0.041). The AS in posterior tear group (24.01 ± 7.69°) was significantly larger than that in middle tear group (18.41 ± 6.13°) (p = 0.029). The LAA in middle tear group (67.41 ± 6.54°) was significantly smaller than that in posterior group (72.74 ± 8.78°) (p = 0.046). The AS in longitudinal tear group (26.86 ± 8.41°) was significantly larger than that in horizontal tear group (22.05 ± 9.47°) (p = 0.035) and L‐shaped group (21.56 ± 6.62°) (p = 0.032). The LAA in horizontal group (70.60 ± 6.50°) was significantly larger than that in L‐shaped group (66.39 ± 7.31°) (p = 0.033). The AI in L‐shaped tear group (0.832 ± 0.074) was significantly larger than that in horizontal tear group (0.780 ± 0.084) (p = 0.019) and irregular tear group (0.781 ± 0.068) (p = 0.047).ConclusionAcromion with a larger AS and a smaller LAA tend to cause anterior or posterior rotator cuff tears rather than middle tears in sub‐acromial impingement. Meanwhile acromion with a larger AS tends to cause a longitudinal tear, a larger LAA tends to cause horizontal tears and a larger AI tends to cause L‐shaped tears.
