Prevalence of the Palmaris Longus Muscle and its relationship with grip and pinch strength: a study in a Turkish pediatric population
HAND, 2013Co-Authors: A Cetin, M Genc, S Sevil, Y K CobanAbstract:Clinical studies generally reveal a trend of variation in the reported prevalence of the Palmaris Longus (PL) Muscle absence. The aim of this study was to find an answer to the question of whether the congenital absence of tendon would affect hand functions or not. A total of 585 subjects, comprised of 305 males and 280 females, were included in our study. Mean age was 8.9 ± 1.4 standard deviation within a range of 6–11. For both sexes, the groups were divided further into three subgroups including 6–7, 8–9, and 10–11 years of age ranges. The grip strength of each hand and pinch strength of all fingers of each subject were measured separately. The absence of PL tendon in the right hand was 35.4 % in females, 25.9 % in males, and 30.4 % in overall average. The distribution of absence of the Palmaris Longus Muscle between both genders was statistically significant. The p value for the right hand was 0.013. The absence of PL tendon in the left hand was 37.5 % in females, 27.9 % in males, and an overall average of 32.5 %. The p value for the left hand was 0.017. In terms of grip strength, a comparison between females and males did not reveal a significant difference. The pinch strength of the second fingers of both hands did not show any difference in both sexes. Pinch strength of the third finger of the right hand was different only in girls of subgroup 6–7 ages ( p = 0.024). In girls, the pinch strength of the fourth finger of the right hand of subgroups 6–7 and 10–11 ages showed difference ( p = 0.009 and p = 0.026, respectively). In boys, the fourth finger in subgroup of 8–9 ages showed significant difference in both hands ( p = 0.011). The fifth fingers of both hands were found different in males for only subgroup of 8–9 ages ( p = 0.001). Pinch strength of the fifth finger of the right hand was different in females for only subgroups of 6–7 and 10–11 ages ( p = 0.023 and p = 0.047, respectively). While grip strength of the hand was not affected in the case of absence of the Palmaris Longus, in both sexes, pinch strength of the fourth and fifth fingers of both hands decreased.

Reversed Palmaris Longus Muscle on MRI: report of four cases
European Radiology, 2000Co-Authors: A. H. Schuurman, A. P. G. Van GilsAbstract:Muscle anomalies around the wrist, in particular the Palmaris Longus Muscle, may cause effort-related median nerve compression. A search of the medical records at our university hospital between 1994 and 1999 revealed four patients with an effort-related median nerve compression due to a reversed Palmaris Longus Muscle. Magnetic resonance imaging was used in the patient work-up and showed an anomalous Muscle in each case that had been missed initially. All four patients were free of pain after simple excision of the anomalous Muscle. Awareness of Muscle anomalies at the wrist on MR imaging is essential in evaluating patients with nerve compressions at the wrist. The purpose of this article is to heighten this awareness in radiologists.

reversed Palmaris Longus Muscle causing effort related median nerve compression
Journal of Hand Surgery (European Volume), 1998Co-Authors: K H Depuydt, A. H. SchuurmanAbstract:Two cases of effort-related distal median nerve compression in the dominant forearm caused by a reversed Palmaris Longus Muscle are presented. Simple resection of the Muscle belly was performed. Carpal tunnel release was done in one case, but in retrospect this was probably not necessary.

bilateral reversed Palmaris Longus Muscle with trifid insertion a rare variation
Journal of The Anatomical Society of India, 2015Co-Authors: Satyajit Bhanu, Vasudha R Nikam, Ashalata D Patil, R S Humbarwadi, Anita Rahul GuneAbstract:The Palmaris Longus Muscle (PL) is described as probably the most variable Muscle in the human body, being variable both in number and form. 1 It can be absent in about 11% of bodies and this absence is more often in females and on the left side. 1,2 Bilateral absence is more common than unilateral absence. 1 Concerning the kind of Muscle, it may be fleshy throughout its entire length or may be digastric. The Muscle may have a proximal tendon or a distal one. It may be fleshy distally and tendinous proximally (Palmaris Longus inversus), being known as the reversed Palmaris Longus Muscle (RPL). The insertion is also highly variable and the Muscle may be attached to the fascia of the forearm, the tendon of flexor carpi ulnaris, the flexor retinaculum, the pisiform or the scaphoid bones, the abductor pollicis brevis Muscle, the fascia or Muscles of the hypothenar eminence, one of the flexor tendons, or near the metacarpophalangeal joints. 1 The distal end of the PL is of clinical interest because of its possible relationships with the median and ulnar nerves. Usually the anatomical variations of the PL are not symptomatic. Nevertheless, a RPL can cause median nerve compression, 2,3 and less frequently ulnar nerve compression. 4

Bilateral reversed Palmaris Longus Muscle with trifid insertion – A rare variation

bilateral reversed Palmaris Longus Muscle with trifid insertion a rare variation
International Journal of Research in Medical Sciences, 2014Co-Authors: Anita Rahul Gune, Anand J Pote, Ashalata D Patil, Priya S Patil, Vasudha R NikamAbstract:Normally the Palmaris Longus Muscle originates from the medial epicondyle of the humerus from common flexor origin. In the middle of the forearm, the Muscle belly forms a tendon which is inserted into the flexor retinaculum and the palmar aponeurosis. In our study after dissection of both forearms of a 45-year-old male cadaver we found a reversed Palmaris Longus Muscle. This means that the Palmaris Longus Muscle was tendinous in its proximal part and muscular in its distal part. The fleshy belly of Muscle was passing over flexor retinaculum, was ensheathed by separate fascia. The Muscle belly was spreading on both the sides of each palm for insertion which was trifid, that is centrally into palmar aponeurosis, laterally continuous with the fascia covering the thenar Muscles and medially with Abductor digit minimi. It was having tendinous interconnection with the Muscle mass of both the sides. Bilateral reversed Palmaris Longus Muscle mentioned in the literature, was a surgical finding in a patient who suffered from edema and pain in the wrist. The overuse of the reversed Palmaris Longus Muscle can lead to the Muscle’s local hypertrophy. As per the literature a reversed Palmaris Longus Muscle may cause a compartment syndrome with pain and edema in the wrist area, the carpal tunnel syndrome and Guyon’s syndrome. The variation is also useful to the hand surgeon, as the Palmaris Longus Muscle is an anatomical landmark for operations in this area.
