Abstract
The Importance of Dorsoulnar Flap in The Thumb’s Pulp Reconstruction - A Case Report and a Review of the Literature
Highlights
The arterial supply of the thumb differs greatly from that of the other fingers
The ulnar dorsal digital artery of the thumb, which originates from the palmar arteries at the head of the first metacarpal bone, continues distally via the proximal nail fold arcade, and is nourished by the palmar anastomosis at the level of the neck of the proximal phalanx
By reference to anatomical facts (1), we present a case of simple local flap, a dorsoulnar flap of the thumb, which presents a possibility to cover the extensive distal and pulpal thumb’s defects
Summary
The thumb’s dorsal collateral arteries are the subject of comprehensive studies. The extensive loss of the thumb’s pulp with or without bone exposure is a major problem for the patient and remains a challenge to take up for the surgeon often brought to cover the losses using local and remote flaps. The ulnar dorsal digital artery of the thumb, which originates from the palmar arteries at the head of the first metacarpal bone, continues distally via the proximal nail fold arcade, and is nourished by the palmar anastomosis at the level of the neck of the proximal phalanx. By reference to anatomical facts (1), we present a case of simple local flap, a dorsoulnar flap of the thumb, which presents a possibility to cover the extensive distal and pulpal thumb’s defects. We present a case of a reconstruction of an extensive thumb’s pulpal defect using the dorsoulnar flap specifyin its technique and its therapeutic interest
