“…3 – 5 , 7 , 10 , 13 , 16 , 21 The prevalence of os acromiale in Thailand is relatively low: 2.13% in patients with shoulder symptoms, as found by this MRI analytic study. With the prevalence determined from previous studies of other East Asian population, this research proves that the prevalence of os acromiale in an Asian population is lower than in other ethnicities—for example, 0.7% in South Korea 10 (plain radiographs with or without MRI) and 0.9% in Thailand 1 (plain radiographs with 3-dimensional CT). Literature examination regarding the prevalence of os acromiale across various population is summarized in Table 3 .…”

“…This finding is in agreement with other studies. 1 , 10 , 15 Moreover, in patients with RC-related pain, only 1 out of nearly a thousand had been diagnosed with symptomatic os acromiale by the history of pain at the acromial region and marked tenderness at the unfused acromion, with the presence of os acromiale in the transaxillary radiograph and MRI scans. This patient required intervention to manage the painful symptoms.…”

“…The formula and parameters are in reference to a study in which CT scans of the shoulder were performed, showing that 1 in 108 was identified with os acromiale. 1 This translates to a proportion of 0.00925. With this parameter in mind, the minimum sample size for this study was calculated as 609 to be statistically significant.…”

Background: Os acromiale is an anatomic variant in which the acromial ossification center fails to fuse. It may lead to painful shoulder conditions and surgical intervention may be required for treatment. The prevalence of os acromiale in South Koreans (0.7%) has previously been the representative number for the Asian population, and it is lower than that in the Black and White populations. Purpose: To determine the prevalence of os acromiale in Thai patients with shoulder disabilities who underwent magnetic resonance imaging (MRI). Study Design: Cross-sectional study; Level of evidence, 3. Methods: We retrospectively reviewed the MRI scans of patients with shoulder disabilities between January 2019 and May 2021 at a single institution. The relationship of sex, age, and shoulder diagnosis to the presence of os acromiale was then analyzed. Results: A total of 940 MRI scans in 848 patients were evaluated, of which 20 shoulders were detected to have os acromiale, a prevalence of 2.13%. The mean age of the patients was 60.25 years, with 60% being female and 40% male. Of the 20 os acromiale cases, 17 (85%) were preacromiale, 1 (5%) mesoacromiale, and 2 (10%) meta-acromiale. The associated diagnoses were as follows: 75%, full-thickness rotator cuff (RC) tear; 10%, partial-thickness RC tear; 5%, RC tendinopathy with symptomatic os acromiale; 5%, anterior shoulder instability with full-thickness RC tear; and 5%, frozen shoulder. Age, sex, and associated shoulder disability were not associated with the presence of os acromiale. Conclusion: In Thai patients with shoulder problems who required MRI evaluation, the prevalence of os acromiale was 2.13%. This is lower than the prevalence from other ethnic groups but slightly higher than that from the same ethnic group (Korea). There was no relation between the presence of os acromiale and shoulder pain, regardless of diagnosis.

“…In contrast, all other pathologies were commonly observed in patients of a younger age, with acromial spur being significantly more common. Nontraumatic RC tears have postulated to be a sequel of the repetitive back and forth movement of the tendons due to osteoarthritic changes in the coracoacromial joint, abnormalities in coracoacromial arch appearance, or developmental anomalies such as Os acromiale [ 20 ]. Furthermore, coracoacromial spurs, abnormal coracoid morphology, increased pillar angulation, decreased interpillar distance, or shortened pillar length can contribute to RC tears [ 21 ].…”

Rotator cuff (RC) and long head of the biceps tendon (LHBT) tears are common shoulder problems presented to the orthopedic clinic. The aim of this study was to assess the association between RC and LHBT tears among a Saudi population sample. A total of 243 patients who were diagnosed with shoulder pain due to RC or LHBT tear between 2016 and 2018 using a magnetic resonance imaging scan were included in this study. Females comprised 66% of the sample, and 59% (n = 143) of the shoulders were on the right side. The mean age of the patients was 58 ± 11 years, ranging from 23 to 88 years. A significant association was detected between the LHBT and RC tears (P < 0.001). Out of 26 cases showing RC and LHBT tears, 81% had a full thickness tear, whereas 19% had a partial tear. The LHBT tears were presented significantly in 48% of cases with at least two completely torn RC compared to 10% in cases with one completely torn RC (P < 0.001). The LHBT tear was significantly observed in shoulders with RC tears including the tendons of subscapularis, supraspinatus, and infraspinatus, but not the teres minor (P < 0.001). Both types of tears were presented significantly in senior patients aged more than 65 years compared to younger patients (P < 0.01). Thus, the LHBT should be assessed carefully in shoulders with more than one RC tear or in chronic cases.
