Foramen for Branch of Interosseous Recurrent Artery on the Supinator Crest of Ulna

A study of the supinator crest of ulna was carried out in 387 dry ulna bones and by dissection of 23 upper extremities of cadavers and a foramen in the supinator crest of ulna was found close to the radial notch in 5.75 of bones. In the cadaveric dissection study it was found that a branch of 'Interosseous Recurrent Artery' passed through this foramen of 'Supinator Crest'. This study is very significant because the existing textbooks of anatomy and available literature do not describe any such foramen or groove of supinator crest through which a branch of interosseous recurrent artery passes.
