Morphometric analysis and surgical anatomy of coracoid process and glenoid cavity

This study was designed to study the morphometric dimensions of coracoid process and glenoid cavity of scapula and to ascertain any correlation involving them. The comprehension of standard morphometric measurements of coracoid process and glenoid cavity is missing in the academic literature. Its awareness is imperative in trauma cases, surgical interventions and replacement surgeries in the shoulder region. For this investigation 69 dry adult scapulae (45 of right side and 24 of left side) of Asian origin without any apparent damage to their osseous structure were studied. The present study demonstrates the analysis of various dimensions of coracoid process and glenoid cavity. Pearson correlation (r-coefficient) was positive for glenoid cavity vertical and horizontal dimensions. The interrelation between all the parameters was highly significant; sig (2-tailed) test was 0 and p value as 0.1, an interesting trend. Variation of dimensions of coracoid process and glenoid cavity are important for radiologist and orthopaedic surgeons for diagnosing various pathologies and plan for repair. The data base provided in the present study is not only helpful in the present day scenario, but with advancement of techniques and advent of various replacement procedures, these dimensions can serve as a baseline and potential prospect for coracoid process replacement surgeries in future.
