Abstract

Introduction: Evolution resulting in acquisition of bipedal gait has led the human beings to gain free upper limb movement. The scapula hence provides a strong and stable attachment for muscle activity around the scapular angles. Sometimes due to excessive stress and overuse of a particular muscle their point of attachment on scapula gets modified resulting in change in angulation and morphology of muscle hence kinesiometry gets altered leading to various shoulder pathology.

Method: Following study measures different angles of scapula namely superior angle (SA), inferior angle (IA), medial/spinovertebral angle (MA), lateral angle (LA), glenoid inclination angle (GIA), gleno-polar angle(GPA), acromial angle (AA) and coracoid angle (CA) in 68 scapulas (R:L= 50:50) obtained from Department of Anatomy, North Bengal Medical College, Darjeeling.

Result: Mean value and SD for Superior angle was 89.57º ± 10.47º, Inferior angle was 44.85º ± 8.14º, Medial angle 156.02º ± 9.11º, Lateral angle 62.38 º± 10.05º, Glenoid inclination angle 12.97º ± 2.80º, Gleno-polar angle 38.65º ± 5.65º, Acromial angle 102.54º ± 14.26º and Coracoid angle 88.41º ±9.12º.

Conclusion: Measurement of all angles on the right scapulas was greater than that on the left side except medial angle, gleno-polar angle and coracoid angle. The latter two angles also had a significant correlation between right and left scapula.

Keywords: Angles of scapula (superior, inferior, medial, lateral, glenoid inclination, gleno-polar, acromial, coracoid ) kinesiometrics, morphology of muscle, clinical significance.
