Study of Anatomical Justification of Coracoacromial Arch Impingement Due to Diverse Morphology of Acromion Process by Radiographs | Chapter 5 | Recent Developments in Medicine and Medical Research Vol. 12

 According to Beglani, Edelson, and Traitz, the purpose of this study was to determine the various morphologies of the acromion process on radiographs. For this experiment, 260 radiographs were taken, including 200 radiographs of impingement patients and 60 radiographs of healthy people. This study included 33 Type I radiographs, 137 Type II radiographs, and 30 Type III radiographs, with Type II radiographs outnumbering Type I and Type III among symptomatic patients, according to Beglani. There were 7 Type I radiographs, 52 Type II radiographs, and 1 Type III radiograph in normal patients, with Type II radiographs being more prevalent than Type I and Type III, with the Type III acromion process being physically responsible for impingement. In patients with shoulder pain, 56 radiographs of Cobra shape, 109 radiographs of Intermediate shape, and 35 radiographs of Square tip were found, while 4 radiographs of Cobra shape, 47 radiographs of Intermediate shape, and 9 radiographs of Square tip were found in patients without shoulder pain, according to the Edelson and Traitz classification. In the majority of cases, the Cobra shape acromion is the cause of impingement; also, the Cobra shape acromion transforms to Type III acromion faster than the Square tip and intermediate Shape acromion.

Furthermore, we can see that the Coracoacromial arch distance in Type III acromion is substantially lower than in other forms of acromion. The P value, according to Beglani, is 0.000. The P value for coracoacromial arch is also 0.001, according to Edelson and Traitz, indicating that it is very significant. In normal radiographs of patients without shoulder pain, the p value is not significant.
