DESCRIPTION OF THE ONE FLAP TECHNIQUE FOR THE SURGICAL TREATMENT OF SYNDACTYLY

Abstract

Syndactyly is a congenital defect of the fingers or toes that can cause aesthetic and functional problems. In this condition there is a defect in the separation of the parts, according to the Swanson Classification, determined between the sixth and eighth week of intrauterine life and representing approximately 20% of all hand malformations. This pathology is the second most common congenital anomaly of the hand and has an incidence of 1:2000 to 3000 live births. It is one of the most heterogeneous deformities known in the literature, with unilateral, bilateral, symmetrical and asymmetrical variations. It occurs twice as often in boys. The aim of this study is to describe a new skin flap design for the treatment of syndactyly. This is a descriptive study, as it aims to detail the surgical technique using different processes for the treatment of simple or complex, incomplete or complete syndactyly.The study maintains the principles of the digital commissure reconstruction approach, adequate skin coverage and reconstruction of the nail bed, presenting a new flap associated with polypropylene coverage, solving the disadvantages of using a skin graft, such as deformities at the recipient site and morbidity of the donor area.
