ASSOCIATION CLINICAL-RADIOGRAPHIC OF THE ACROMION ÍNDEX AND THE LATERAL ACROMION ANGLE

ABSTRACTObjective: To evaluate the clinical-radiographic subacromial disease symptoms correlated with adaptation of the measure of lateral acromion angle and its respective measuring radiographic acromial index. Methods: In the period between october 2010 and february 2011 were evaluated 55 painful shoulders with Neer test and true anteroposterior radiography. Patients were divided into two groups, with Neer test positive and negative. The index measuring the acromion and the lateral acromion angle have been standardized, and compared using statistical averages of 0.7 and 75°, respectively. Results: The predominant symptom in the population, females (72.73%), age less than 59 years (62.5%) and dominant side (65.31%). The acromion index above 0.7 was found to be symptomatic in 66.67% and lateral acromion angle less than 75 ° in 82.61%. When associated methods, 62.5% had positive clinical (p<0.083). Conclusion: The determination of radiographic acromial index and the lateral acromion angle together seem to be statistically associated with the disease of subacromial impingement.
