Abstract

Palmaris longus (PL) is phylogenetically classified as a retrogressive muscle with a long tendon. The length and location of the PL tendon makes it very useful in reconstructive surgery. Agenesis of PL tendon shows strong racial variations. Past studies show absence of 2.8% to 25% depending on ethnicity. Chinese have a low absence rate of 6.0% whilst Caucasian subjects had a high absence rate of 25%. The aim of this study is to determine the incidence of unilateral and bilateral absence of PL tendon for Eastern Azerbaijan region of Iran and surveying the genetic factors and environmental effects to lack of PL tendon.
