Anant Sachan ^[2] | Rajkumar ^[50]

Abstract: Palmaris Longus Muscle is one of the most variable muscle in the human body (Brones & Wilgis, 1978) in the concern of presence and absence. Palmaris longus (PL) muscle, although of little functional use to the human upper limb, assumes great importance when used as a donor tendon for transfer or transplant or grafting. It is The most desirable tendons in reconstructive surgery. In the present study, 500 Medical students (210 males and 290 females) of different ages from Teerthankar Mahaveer Medical College & Research Centre, Moradabad were examined for the presence or absence of the PL tendon, using the conventional four tests are following, Schaeffers test, Thompsons test, Mishras test, Pushpakumakars two finger sign method. PL agenesis was further analyzed statistically for differences in the prevalence and agenesis of PL with regard to sex and body side. I was observed the 290 females, the palmaris longus muscle is present in 72.06 % (n=209) of the total population. Bilateral absence of the muscle is found in 18.96 % (n=55) of the sample. Unilateral absence on the left side was found in 5.86 % (n=17) of th cases and on the right side in 3.10 % (n=9) of the cases and 210 males, 97.61 % (n=205) had the palmaris longus muscle on both the left and the right sides. In the sample population, 0.47 % (n=1) had bilateral absence of palmaris longus. The muscle was absent on the left side in 0.95 % (n=2) of the cases and on the right side in 0.95 % (n=2) of the cases.
