| digital reflex | <clinical sign> In latent tetany mild mechanical stimulation of the trigeminal nerve causes severe pain, flexion of the terminal phalanx of the thumb and of the second and third phalanges of one or more of the fingers when the volar surface of the terminal phalanx of the fingers is flicked. Synonym: digital reflex, Hoffmann's reflex, snapping reflex. (05 Mar 2000) |
| digital subtraction angiography | Computer-assisted roentgenographic angiography permitting visualization of vascular structures without superimposed bone and soft tissue density; images made before and after contrast injection allow subtraction (separation and removal) of opacities not enhanced by the contrast medium. Other image-processing can be performed. Contrast material may be injected intravenously or in lower-than-usual amount intra-arterially. (05 Mar 2000) |

| infantile digital fibromatosis | Multiple fibrous flesh-coloured nodules on the extensor aspect of the terminal phalanges of adjacent digits of infants and young children which often recur after attempted excision, do not metastasize, and may spontaneously regress in two to three years; composed of spindle cells containing cytoplasmic inclusions believed to be derived from myofibrils. Synonym: infantile digital fibromatosis. (05 Mar 2000) |
| tendinous chiasm of the digital tendons | Crossing of the tendons, the passage of the tendons of the flexor digitorum profundus (flexor digitorum longus in the foot) through the interval left by the decussation of the fibres of the tendons of the flexor digitorum superficialis (flexor digitorum brevis in the foot). Synonym: chiasma tendinum, Camper's chiasm. (05 Mar 2000) |
