Radiographic study of anatomical basis of Coracoacromial arch impingement due to varied morphology of acromion process
Journal Title: INTERNATIONAL JOURNAL OF RECENT TRENDS IN SCIENCE AND TECHNOLOGY - Year 2018, Vol 26, Issue 2
Abstract
The purpose of this study to know the different shapes of acromion process according to Beglani and Edelson and Traitz on radiographs. For this study 260 radiographs were taken - 200 radiographs of patients having shoulder pain due to impingement and 60 Radiograph of normal patients without shoulder pain. In this study according to Beglani, there were 33 radiographs of Type I, 137 radiographs of type II and 30 radiographs of Type III, Type II radiographs being more in number than Type I and Type III in case of symptomatic patients. In case of normal patients, there were 7 radiographs of Type I, 52 radiographs of type II and 1 radiographs of Type III, Type II radiographs are more in number than Type I and Type III and anatomically Type III acromion process is responsible for impingement. According to Edelson and Traitz classification, 56 adiographs of Cobra shape, 109 radiographs of Intermediate shape and 35 radiographs of Square tip were found in case of shoulder pain patients and in case of normal patients, 4 radiographs of Cobra shape, 47 radiographs of Intermediate shape and 9 radiographs of Square tip were found. In majority of cases Cobra shape acromion is responsible for impingement, also Cobra shape acromion gets rapidly converted into Type III acromion than Square tip and intermediate Shape acromion. Also, we see the Coracoacromial arch distance is very less in Type III acromion than other Type of acromion. According to Beglani, P value is 0.000. According to Edelson and Traitz also P value for coracoacromial arch is 0.001 which ishighly significant. In normal radiographs of patients without shoulder pain p value is not significant.
