Background: The palmaris longus muscle, the thinnest of the carpus flexor muscles, originates from the medial epicondyle of the humerus and is located in the anterior part of the forearm, covered by fascia. It occupies the space posterior to the superficial flexor digitorum and lies medial to the radial flexor of the carpus. In distal part of forearm, its small, fleshy belly stretches downward and becomes a tendon. Aim: The purpose of this cadaveric research is to develop a method for accurately estimating the length of the palmaris longus tendon prior to reconstructive surgery. Material and Methods: 50 limbs (25 right and 25 left) representing a variety of age groups and sexes (33 male cadavers and 17 female cadavers), made up the study's subject matter. The Department of Anatomy made the limbs accessible. In the research, only limbs that displayed the whole anatomy of PLM were considered. Limbs lacking PLM or exhibiting any other abnormality were not included in the research. The FAL was measured from the top of the olecranon to the ulnar styloid apophysis (the styloid process of the ulna that extends from posteromedial aspect at its distal end). Results: Male cadavers had mean PL-TL and PL-TW measurements of 16.01±1.11 cm and 0.51±0.03 cm, respectively, whereas female cadavers had mean measurements of 15.15±1.01 cm and 0.38±0.02 cm. In comparison to female cadavers, male cadavers were found to have greater of these measurements. The mean FAL was found to be greater in male cadavers than in female cadavers, measuring 24.01± 2.18 cm in male cadavers and 20.89± 2.08 cm in female cadavers. The mean PL-TL was somewhat larger on the left (16.03±2.05 cm) than the right (15.98±1.01 cm). The mean PL-TW on the right side was somewhat higher (0.52±0.03 cm) than the left (0.44± 0.04 cm). The average FAL on the right side was somewhat higher (23.05±1.69 cm) than the average FAL on the left side (22.85±1.55 cm). Conclusion: There was a link that was statistically significant between the TL-PL and the FAL that was noticed. The findings suggest that it is possible to make an estimate of the PL-TL prior to undergoing surgical intervention in cases where the tendon has to be used as a transplant. Even in situations when there is no PL to be found, a suitable donor will be the one from whom a required TL may be taken and used for reconstruction.
