Palmaris Longus (PL) is a muscle of the forearm, i.e., not functionally necessary and does not exist in all people. It is a choice for tendon graft and investigating its prevalence is of clinical importance. During April-October 2009, 102 cadavers (78 males, 24 females) were bilaterally necropsied for PL exploration in Zanjan City, Iran. PL Absence (PLA) was observed in 37 (36.3%) cases (28 males, 9 females). PLA prevalence was similar in men (36%) and women (37.5%). Of PLA cases, 19 (51%) were unilateral (14 males, 5 females), and 18 (49%) were bilateral (14 males, 4 females). In conclusion, PLA prevalence of 36.3% in our population was similar to other studies conducted in Iran. We found no gender difference in PLA prevalence and its patterns. Due to geographical variability in PLA rate, future regional and national studies with more magnificent sample sizes are recommended to determine the prevalence and gender-specific patterns of PLA.
