Abstract: Aim: To study the morphology and morphometry of bicipital groove of dry humerus in eastern Indian population. Material and Methods: 86 dry adult humeri were investigated. The Bicipital Groove of Humerus was noted for morphological and morphometric variations in terms of length of medial and lateral wall, width and depth by using Digital Vernier Calliper and also for presence of Supra Tubercular ridge of Meyer. Result: Morphometric measurement of the bicipital groove were carried out of 86 humeri (49 right and 37 left side). The mean maximum length of humerus was 31.142 2.41cm.The mean length of medial and lateral wall of bicipital groove on right side was 23.98±1.05mm and 32 .15±2.15mm respectively and on left side was 23.13±2.46mm and 31.95±0.28mm respectively. The mean length of right side bicipital groove was 83.93 5.68mm and on left side was 86.59 6.28mm. The mean width of bicipital groove on right and left side was 6.79±0.53mm and 7.56±1.05mm respectively. The mean depth of bicipital groove on right side was 4.17±0.56mm and on left side 5.01±1.02mm. A Supra Tubercular ridge of Meyer was present in 29(33.7%) out of 86 humeri of which 18 were present on the right side.
