A Study on the Absence of Palmaris Longus in a Multi-racial Population
Abstract
Palmaris longus is a dispensable muscle with a long tendon which is very useful in reconstructive surgery. It is absent 2.8 to 24% of the population depending on the race/ethnicity studied. Four hundred and fifty healthy subjects (equally distributed among Malaysia’s 3 major ethnic groups) were clinically examined for the presence or absence of palmaris longus. This tendon was found to be absent unilaterally in 6.4% of study subjects, and bilaterally in 2.9% of study participants. Malays have a high prevalence of palmaris longus absence at 11.3% followed closely by Indians at 10.7% whilst Chinese had a low absence rate of 6.0%.
