Sensation Assessment of Dorsal Digital Artery Perforator Flap In Fingertip Reconstruction (A Prospective Study

Abstract

Fingertip amputation is really a complicated issue because high rate of incidence and highly specialized functions of it. Surgeons make their efforts to reconstruct fingertip normal shape and restore its function in the form of restoration of sensations, and it is a challenging procedure. The fingertip is composed of; distal phalanx , the nail complex, Fibrous connective tissue network with the subcutaneous tissues, Vascular network, Nerves with end organs and the nonperionychial skin. Assessing both slowly and quickly adapting fibres in the fingertips is essential for establishing a baseline for sensation and developing a logical, sequential treatment plan for sensory re-education. In this study we repaired fingertip amputations by DDAP flap without nerve coaptation and after a period of recovery, regaining of flap sensation was evaluated. We found that this flap has considerable sensory return fair enough that enable patient to manipulate and deal normally with life activities and protect his hand and fingers.
