Evaluation of Methods of Claw Finger Correction Using the Finger Dynamography Technique

Abstract

Finger dynamography is a bedside technique for evaluation of the moving abilities and working space of the hand. Various operative procedures used for correcting the claw finger deformity restore the functional abilities to a varying extent. The palmaris longus transfer with insertion into A1–A2 pulley appears to be a better procedure than lateral band insertion, extensor diversion or extensor many-tail procedures. The use of palmaris longus as a motor seems to have advantages over flexor digitorum superficialis transfer where removal of FDS as a motor produces local deficits.
