The palmaris longus tendon is the most frequently harvested tendon for reconstructive plastic and hand surgical procedures. A question patients often ask is whether loss of the palmaris longus will result in any functional deficit. In order to answer this question, the presence or absence of the palmaris longus muscle was clinically determined in 418 normal Asian subjects. All subjects also had their grip and pinch strengths measured. No statistically significant difference was seen in the grip or pinch strength measurements between subjects who had a palmaris longus tendon and those who did not. This study demonstrates that absence of the palmaris longus is not associated with a decrease of grip or pinch strength.
