A Salvage Procedure in the Treatment of the Boutonnière Deformity Caused by Contact Burn and Friction Injury

Abstract

Contact burns and friction injuries to the dorsum of the finger denude it of full thickness of skin and central extensor tendon tissue, rendering the primary repair of the resultant boutonnière deformity difficult. A salvage procedure that offers both functional restoration and cosmesis is described. Here the unaffected lateral band aattachments are transposed en-masse, as a composite flap, to the dorsum of the finger to establish active extension of the proximal interphalangeal joint.
