One in Four Flexor Digitorum Superficialis Lasso for Correction of the Claw Deformity.

Abstract

In continuation of the author’s work on ‘lasso’ principle, flexor digitorum superficialis split in to four tails and looped around A1 pulley has been described in this article to correct the ulnar claw and to correct the total claw hand when used along with opponensplasty as a one stage technique. This operation has the advantage of retaining superficialis tendons of the other fingers for better power grip and the avoiding swan neck deformity.
