“…Type III (14%), Type I (34.6%) and Type II (51.1%) (Table II). This trend in acromial type incidence was in accordance with that reported by other authors (Edelson & Taitz, 1992;Getz et al, 1996;Nicholson et al;MacGillivray et al, 1998;Kim et al, 1999;Kane et al;Paraskevas et al;Potau et al;Saha et al, 2011;Mohamed & Abo-Sheisha, 2014) (Table II).…”

SUMMARY: The acromion is classically described as one of the three scapular processes. Its antero-inferior aspect has been identified as the prime region of rotator cuff pathology. The purpose of this study was to determine the morphologic state of the acromion and the relative subacromial architecture within a South African population. The sample series comprised the morphological observation of one hundred and eighty-two scapulae specimens (n= 182). The classification scheme as stated by Bigliani et al. (1986) was employed. The morphometric architecture of the subacromial space was also investigated (n= 120). (a) Acromial Type: (i) Type I (flat inferior surface) 34.6%; (ii) Type II (curved inferior surface) 51.1%; (iii) Type III (hooked inferior surface) 14%. (b) Shape of the subacromial space: (i) rhomboid 60.8% (ii) triangular 10%, (iii) trapezoid 29.2%. Since this study investigated the acromial morphology and its association with the relevant demographic factors specific to the South African population, it may prove beneficial to the South African population as a whole. In addition, statistically significant differences were obtained for the correlation of several morphometric and morphological parameters of the subacromial architecture with age, sex, acromial type and shape of subacromial space. A unique trapezoidal subacromial space was also observed. As the variable acromial types and subacromial morphology have been reported to lead to the narrowed subacromial space and subsequent subacromial syndromes, the association between the respective morphometric and morphological parameters may provide predictive values to assist in the diagnosis and assessment of the cause of rotator cuff disease.

“…The results of the shape of the acromion and its different dimensions demonstrate that in the scapulae studied, the acromion type I presented in 8%, of type II in 50%, and in type III in 42%, indicating a greater presence of acromion type II in the population studied, according to studies performed by Getz et al (1996); Shah et al (2001); Natsis et al (2007); Oda et al (2000); Paraskevas et al (2008), whose investigation was carried out in macerated scapulae through visual inspection, the classification method carried out through images, also indicate a greater percentage of this type of acromion, even in those cases where authors as Shippinger et al (1997), Wang et al (2000), in their research found a greater percentage of acromion type I and II.…”

SUMMARY:The morphology of the acromion, its relation to the coracoid process and the supraglenoid tubercle is important in the determination of the dimension of the subacromial space, considering that the variations of these structures can promote pathologies such as impingement syndrome of the subacromial space. There is little information on the different dimensions and forms of the acromion. We studied in 36 scapulae at the museum of the Anatomy Unit, Universidad de La Frontera, the following parameters: length, denseness, width, anterior projection, distance acromiocoracoid and acromion supraglenoid. According to this form, the type was qualified in acromion type I (plane) type II (curved) and type III (hooked). The averages of the variable length, anterior projection were statistically significant in the acromion of the right side. In relation to its classification 8% was type I, 50% type II, and 42% type III. The anatomically obtained information will allow health professionals to access new morphometric information regarding the acromion and use it as a base for future pathology investigation of the upper arm.
