( A ) The clinical of the dorsum of the operated wrist with schematic markings of the radial artery course (red line solid and dotted), 1,2-ICSRA, dorsal bone graft, and its rotation over scaphoid nonunion site. ( B ) The direction and position of the Doppler probe over anatomical snuffbox and ( C ) the corresponding Doppler images showing 0.12-cm large sized radial artery and its origin of dorsal branch, which is measured as 0.19 cm. The radial artery continues to form a dorsal radiocarpal arch. ( D ) The different direction and position of the Doppler probe far from anatomical snuffbox and over the scaphoid shows the vascularized bone graft with 0.05-cm small vessel 1,2-ICSRA. The reverse pattern of 1,2-ICSRA vessel confirms its rotation from the dorsal radius. ICSRA, intercompartmental supraretinacular artery.
