Associação clínico-radiográfica do índice acromial e do ângulo de inclinação lateral do acrômio

“…According to Serna and Velásquez (7) , the assessment of the acromial index by MRI presents highly statistically significant values, with greater reliability than when evaluated radiologically. However, highly significant results were also found in the radiographic assessment (8) . Our findings were without statistical significance in relation to age, sex, profession, race, smoking, occupation, dominance, and side of the lesion.…”

“…higher than 0.7 in 66.67% of the population sampled. We used this cut-off point, as shown in the works of Nyffeler et al (6) and Miyazaki and Fregoneze (8) , in which the values found were 0.73 ± 0.06 and 0.7194, respectively. However, our findings were not statistically significant (p < 0.572).…”

“…The radiographs were standardized, with correction of anteversion of the glenoid cavity (true AP) and the proximal region of the humerus in neutral or medial rotation, all performed by the same radiology technician. Because it is an index, the focal-film distance was not considered significant (8) . The patients were divided into two groups: symptomatic (positive Neer test), 37 (67.27%), and non--symptomatic (negative Neer test), 18 (32.73%).…”

“…The vector resulting from the force originates in the lateral projection of the acromion which, in turn, is related to the deltoid insertion, causing the humeral head to rise up and impinge against the subacromial surface during abduction of the upper limb ( Figure 3) (6)(7)(8) . The greater the lateral projection of the acromion, the higher the acromial index will be, and consequently, the greater the likelihood of the occurrence of impingement syndrome (6) .…”
