The common interosseous artery is main branch the ulnar artery which divides into anterior and posterior interosseous branches. The current study investigates common interosseous artery and its branch to provide detailed information regarding the morphology which would be of use to clinicians, orthopaedic surgeons, plastic surgeons and anatomists. Routine dissections of the right and left upper limb of 34 adult cadavers (20 male and 14 female: mean age 78.9 year) were undertaken. The common interosseous artery presents in 67.6% whereas it is congenital absence in 32.4%. The origin distance of bifurcation of common interosseous from the ulnar artery origin is between 33.11 and 33.45 mm. The anterior and posterior interosseous arteries present in 98.5% and 92.9% whereas they are congenital absence in 1.5% and 7.1% respectively in total cases. Further, the anterior and posterior interosseous arteries present in 92.9% whereas they are congenital absence in 7.1% in female. The external diameters of the common, anterior and posterior interosseous arteries at their origin ranged from 1.39-1.86 mm, 1.59-1.80 mm and 1.80-1.95 mm respectively. Understanding the variability of common interosseous artery and its branch may help the clinicians and surgeon for clinical use in heart, carotid and flap transplantations.
