Background: The prevalence of palmaris longus agenesis (PLA) has been variously reported to be from 1.5% to 64% in different ethnic groups. Finding the state of PLA among Iranian people was the aim of this study. Methods: 1008 participants were included in this descriptive study during a 6-month period in a teaching hospital in Tehran-Iran. The Schaeffer test was used to detect the presence or absence of palmaris longus. The role of gender and handedness was also assessed in PLA. Results: The prevalence of PLA was estimated at 22.8% - 10.2% agenesis on the right side, 5.9% on left side and 6.7% on both sides. The relationship between PLA and gender didn’t appear to be significant. Right handedness was seen in 90.9% of cases with PLA and 72.5% of those without PLA (p=.000, OR=3.8). Conclusion: The prevalence of PLA in Iranian people studied, were comparable to the average Caucasian values in the literature.
