Direct and Reversed Dorsal Digital Island Flaps: A Review of 65 Cases

At final follow-up, sensory restoration of the flap is measured using the static 2-point discrimination (2PD) test and Semmes-Weinstein monofilament (SWM) test. Active motion of the joints is measured using a standard hand goniometer. For the direct DDIF, total active motion is calculated as the sum of degrees of active flexion of the interphalangeal and the metacarpophalangeal joints subtracted from the degrees of extension deficit. For the reversed DDIF, total active motion of the donor finger is calculated as the sum of degrees of active flexion of the proximal and distal interphalangeal joints subtracted from the degrees of extension deficit.
