Abstract

Coracoid process (C.P) is projected part of scapula from its antero-lateral aspect, having proximity with ligamentous and neurovascular structures. Its tip appears in 5 different shapes. Angulations of 2 parts (superior pillar and inferior pillar) of C.P play a vital role in its position and inclination. C.P is involved in various pathological conditions like subcoracoid impingement syndrome, coracoid fracture, anterior shoulder instability, rotator cuff tears and used in reconstruction surgeries. Knowing its angulations help radiologist in proper angulation of beam of radiations for optimum visualization of C.P and for assessing proneness of diseases around shoulder joint and for planning before taking for surgeries. To assess different types of C.P, to compare morphometric and angular measurements in each type of C.P on both sides. 200 dry Scapulae were placed in 3 different planes and images were taken. Then studied in an app ‘Image J’. Linear measurements and angular measurements of both processes in relation to Glenoid plane in coronal, axial and sagittal planes were studied. By using SSPS7.7, results are mentioned in average with standard deviations. Chi square test is conducted of comparing various measurements and angulations for significance. Type II was most the commonest type of C.P and type III was least in occurrence (53% and 5.5%). LxWxH of superior and inferior pillars were 3.6×1.4×0.65 cms and 1.14×2.0×0.8 cms, respectively. Superior and Inferior pillars were largest in length in type I CP on both sides and in type V on both sides p-0.003 and 0.0179, respectively. Both pillars were widest in type I C.P 3.5±0.3cms and 2.0±0.2 cms. Mean angles of inferior pillar in 128°, 137° and 54° in saggital, coronal and axial planes respectively. Superior pillar’s mean angle in axial plane was 134°. In coronal plane inferior pillar showed highest angle was in type IV CP (142° and 145.3°respectively on each side) and lowest in type V CP (127.7° and 129° respectively on each side). This finding was highly significant with p-0.0004 and 0.008. This parameters may help surgeons in deciding size and orientation of screws. Angulation of C.P can be utilized by radiologist for proper angulation of beams of radiations during assessment.
