“…The present study demonstrated that bilateral absence of PL tendon was common in female (14.2%) than in male (10.7%) and these findings coincided with findings of various studies conducted among different populations. 18,23,26,29 In relation to the handedness, left palmaris longus agenesis was more common in female left handed individuals (45.4%) than in male (15.4%) which was similar with the studies conducted in Serbia and Greece. 24,27 The similar study had also stressed to the fact that there was a strong correlation between palmaris longus agenesis and left hand dominance.…”

Palmaris longus is a thin fusiform shaped muscle which terminates as a long slender tendon and enters the palmar aponeurosis of the hand. It is also one of the most variable muscles in the body. The main objective of this study was to detect its tendon in both hands and to compare and analyse it in relation to gender and hand dominance. An observational, descriptive study was conducted over a period of 11 months from October 2021 – August 2022 in the Department of Human Anatomy of Nepal Medical College and Teaching hospital, Gokarneshwor – 8, Kathmandu, Nepal. Following tests were conducted for its detection. 1. Schaeffer’s, 2. Thompson’s, 3. Mishra’s test I, 4. Mishra’s test II and Pushpakumar’s test. The results obtained showed that presence of left palmaris longus was more in left handed individuals which was statistically significant with p – value of 0.025. Similarly, presence of right palmaris longus was more in right hand dominant participants. Among the left hand dominant participants, left palmaris longus agenesis was more common in female which was also found to be statistically significant with p-value of 0.009. The knowledge regarding the palmaris longus tendon is of growing interest to surgeons these days for its augmentation, ptosis correction and in facial paralysis management. It gains its importance for autograft as it fulfills the requirement of length, diameter and availability. Hence the study regarding the palmaris longus tendon in relation to its hand dominance and gender can be helpful to surgeons working in various fields.

“…15 Okafor et al documented that the tendon of PL is frequently used as graft for hand and reconstructive plastic surgeries. 4 The use of PL tendon has also been stated in the ligaments and tendon surgeries 17 along with chin and lip restoration procedures. 5 The insight about PL muscle is of vital importance for physicians, radiologists, physiotherapists and surgeons.…”

Palmaris longus is a muscle that is located in the anterior compartment of the forearm. Among the muscles belonging to the flexor compartment of forearm, palmaris longus is located at the most superficial position and that is why it is easy to access. It exhibits high variability and its prevalence ranges between 1.5% and 63.9%. The knowledge of prevalence of agenesis of palmaris longus is essential both in terms of updating anatomical information and also for physicians, radiologists, physiotherapists and surgeons. The surgeons must know about the variability as it may be beneficial while they plan surgeries involving the palmaris muscle as a graft. The current narrative review was planned to highlight the variability pattern of palmaris longus muscle in terms of prevalence, gender and laterality. Palmaris longus agenesis is more common in females and on the left side. Besides, unilateral agenesis is more common compared to bilateral agenesis.

Musculus Palmaris Longus: Influence on Playing Capability of Keyboard Musicians – Preliminary Report

et al. 2018

Musculus Palmaris Longus (PL) is one of the most variable anatomical structures in the human body. Despite being biomechanically active, it is vastly considered to have no impact on the functionality of the upper extremity in the general population. The aim of this study is to examine the relation between playing capability of young musicians and morphology of Musculus PL and to compare it with the relation between manual capability of non-musicians and morphology of their Musculus PL. 42 forearms of 21 healthy individuals (11 musicians and 10 non-musicians) were subjected to Shaeffer’s test and ultrasound imaging and tested by dynamometer for hand grip strength and the first and fifth finger opposition before and after exertion. No difference in morphology pattern was observed between the groups. In the musicians, a substantial loss of a hand grip strength of the left hand compared to the right hand after exertion, regardless of lateralization, was observed. A disproportion in exhaustion of the musician’s hands with unilateral absence of PL was observed – the difference in grip strength between the dominant and non-dominant hand before and after exertion increased over eight times more than in the musicians with bilateral presence. There is no difference in PL morphology between either the musicians or non-musicians. Regardless of lateralization, the musician’s left hand in musicians seems weaker and therefore more prone to misuse related injuries. PL may play a role in musicians in balancing muscular exhaustion.
