“…But conflicting results are demonstrated in some studies that acromion type and parameters were not related with increased risk of SAIS and rotator cuff tear. The sexes were not related to any acromial parameters [ 25 , 26 ]. However, there were some limitations in using imaging study rather than dry bone.…”

Acromion is a major associated structure of subacromial impingement syndrome, one of the most common diagnoses in chronic shoulder pain worldwide. The aims of this study are to study morphometry of acromion and to find risk group using acromial morphometry. Total samples were 392 scapulae. The samples were of both sexes, ranging from the age of 31 to 90. Acromion type and osteophytes were observed. Acromial parameters were measured. The relationships were analyzed among acromion type, acromial osteophyte, acromial parameters, age group, sex and side. Curved acromion had the highest prevalence in all age groups. Hooked acromion had the second highest prevalence since the age of 41. Hooked acromion prevalence was higher in male than in female. The highest prevalence of acromial osteophytes was on anteroinferior surface in all age group. The prevalence of acromial osteophytes on anteroinferior surface and acromial facet increased with age. In addition, acromion type was associated with only osteophytes on anteroinferior surface of acromion. Anterior one-third acromial thickness in the age of 31 to 50 was different from those of 51 to 90. There are differences between all parameters and sexes, but not side. General population with age above 50 and concerned male group with age above 40 who have chronic shoulder pain should be investigated for subacromial impingement syndrome. Surgical treatment is recommended because hooked acromion and osteophytes are mostly the root of problem.

“…Although in three recent studies [ 20 – 22 ], the correlation of CSA with rotator cuff diseases has been strongly criticized, the popularity of CSA has increased over time. Nonetheless, many points on CSA remain to be elucidated [ 23 ].…”

Critical shoulder angle (CSA): age and gender distribution in the general population

et al. 2022

Objective Anatomical parameters and pathologies that can affect the critical shoulder angle (CSA) are subjects of discussion. To date, we do not know if the CSA value changes in the different decades of life in a population characterized by the same ethnicity, nor if there are differences related to gender or side. This study hypothesizes that age and gender may affect the CSA. Methods Patients older than 15 years old affected by a shoulder trauma and who were discharged with a diagnosis of shoulder contusion were enrolled. A true AP view of the shoulder was obtained as well as data regarding age and gender of all participants. The CSA was measured by three authors, and interoperator reliability was assessed. Eight subcategories, according to decades of life, were considered. Finally, the studied population was divided into three subcategories according to CSA values (< 30°; 30–35°; ≥ 35°). Results The initial sample comprised 3587 shoulder X-rays. The interobserver reproducibility was high, with an intraclass correlation coefficient of 0.865 (95% CI 0.793–0.915). Two thousand eight hundred seventy-three radiograms were excluded. The studied group comprised 714 patients [431 females, 283 males; mean age (SD): 47.2 (20.9) years, range: 11–93 years]. The mean CSA was 33.6° (range: 24–50°; SD: 3.9°). The mean CSA values in females and males were 33.7°and 33.5°, respectively. The mean CSA values of the right and left shoulders were 33.3° and 33.9°, respectively (p > 0.05). Linear regression analysis showed a CSA increase by 0.04° every year. The mean CSA in subjects aged between 15 and 19 years was significantly lower than all the other groups, except for patients older than 80 years. No significant differences were found between CSA subcategories, gender, or side. Conclusions In the general population, the mean CSA value was 33.6°. No significant differences were found regarding the mean CSA value according to gender or side. A significant positive linear correlation between CSA and age was detected. In each decade of life, the CSA value, which is genetically determined, shows a large variability. Level of evidence: IV.

“…The angle was similar in people with RCRSP with or without RC tear, and in a group of people with glenohumeral instability (Moses et al, 2006). An association between acromial shape and full-thickness rotator cuff tendon tears may exist (Worland et al, 2003) but many of these tears are asymptomatic and may be part of normal ageing (Lewis, 2016;Lewis, 2009a;Maalouly et al, 2020;Worland et al, 2003).…”
