Abstract :

INTRODUCTION :Palmaris longus muscle originates from medial epicondyle and forms long slender tendon.The palmar aponeurosis is degenerated part of Palmaris longus. Its nerve supply is from median nerve,it is weak flexor.Hence the study of this muscle and its variation is important. AIMS AND OBJECTIVES:To study the variations in the Palmaris longus and to discuss the clinical and surgical implications of these variations. METHODOLGY:This study was conducted in Department of Anatomy of Osmania medical college , koti, Hyderabad. During routine undergraduate dissection on human cadavers(22upperlimbs); 20males & 2female cadavers were dissected for the study. The cadavers with visible trauma, pathology or prior surgeries were excluded from the study. Routine dissection of the upper limb was followed. During the dissection of the anterior compartment of forearm, the Palmaris longus muscle was identified & carefully dissected. At first, the origin was confirmed and then, it was traced towards its insertion. Any variations found were noted and photographed. The results were analysed and compared to previous studies. RESULTS:Unilateral absence of Palmaris longus muscle was found in two male cadavers on left side .The percentage of absence of Palmaris longus muscle is 9 % [one left side –4.5% and the second left –4.5%]. CONCLUSION: Palmaris longus muscle is one of the common flexor muscles of the forearm. The Palmaris longus muscle is considered as the most variable and one of the degenerated muscle of the human body. Precise knowledge of variations in the Palmaris longus is essential for surgeons, orthopaedicians, plastic surgeons, anatomists and researchers
