Abstract

Background: Palmaris longus (PL) is one of the forearm muscles that lie between the flexor carpi ulnaris and the flexor carpi radialis muscles. PL action is flexion of the hand at the wrist and making the palmar aponerurosis tense. Plastic surgeons utilize the Palmaris longus in restoration of lip and chin defects.
Objectives: We sought to determine the frequency of the absence of the palmaris longus in Saudi Arabia among female students in King Faisal University, AL-Ahsa. Materials and Methods:Two hundred normal subjects were chosen randomly from King Faisal University female students. Subjects who had gone through a surgical procedure or have any deformities in the forearm were excluded. We have examined the presence or absence of palmaris longus using three tests. Subjects were asked to do standard test for the assessment of PL tendon.  If PL cannot be detected by the standard test, two more tests were performed to confirm the absence. Results: The overall prevalence of absence both unilaterally and bilaterally is 40.5 %. Unilateral absence was 20.5%. The bilateral absence was 20%. The distribution on the right and left was 29% and 31.5% respectively.
Conclusions: The present study found palmaris longus to be absent equally bilateral and unilateral in more than one third of the sample and significantly more common in the left side.
