“…Previous studies on the incidence of the PL tendon show a wide variation from 0% in a series of 299 Tibbu to 36.8% in a group of 126 Jews and up to 38.2% in a group of 1433 Egyptians 714. Romanes stated that PL is absent in 11% of limbs 14.…”

“…PL agenesis differs according to race, sex, and to the right and left side. There is a wide variation in the incidence of PL ranging from 0% to 63% with an overall 16% unilateral and 9% bilateral absence described in the literature 67. There is paucity of data in the Indian population; therefore, this study was undertaken to know the occurrence of absence of PL in the Indian population.…”

Background:Ethnic variations in the prevalence of the absence of the palmaris longus (PL) tendon are well known. Studies have also attempted to correlate its absence with other anatomical anomalies. However, most studies have been done in Caucasian populations. The present study was undertaken to know the occurrence of absence of palmaris longus in Indian population.Materials and Methods:The presence of the PL tendon was clinically determined in 385 normal Indian men and women using the standard technique. In subjects with an absent PL tendon, three other tests were performed to confirm its absence. All subjects were also examined for the presence of the flexor digitorum superficialis (FDS) in the little finger.Results:The overall unilateral absence of the tendon was 16.9% and the bilateral absence was in 3.3% in our population. There was no significant difference in its absence with regard to the body side or sex. The overall prevalence of the weak FDS in the little finger irrespective of the presence or absence of the PL tendon in our study was 16.10%. If we compare the deficiency of the FDS in the little finger with the absence of the PL tendon, the overall incidence is 4.15% and is statistically significant, while the sexwise distribution of the weak FDS with absent PL tendon was statistically significant in males and in females it was statistically insignificant.Conclusions:The prevalence of the unilateral absence of the PL tendon in an Indian population is comparable to the western population but a bilateral absence is significantly less. In patients with an absent PL tendon, the FDS of the little finger is weak, especially in males.

“…This suggests an active role of the palmaris longus muscle in the determination of the longitudinal disposition of the fibers of the superficial layer through mechanical tension. It may explain why the presence of the palmaris longus tendon is correlated with a significant increase in risk (Powell et al, 1986) of developing Dupuytren's disease (Dupuytren, 1834), which is a common acquired pathological condition with fibrous degeneration of the superficial longitudinal layer of the aponeurosis and the retinacula cutis (Holland and McGrouther, 1997), while the deep transverse layer is involved only rarely and in late stages of the disease.…”

The palmaris longus muscle and its relations with the antebrachial fascia and the palmar aponeurosis

et al. 2009

The palmaris longus (PL) is a muscle of the forearm with a long distal tendon that is continuous with the palmar aponeurosis (PA). It is generally assumed that the muscle lies deep to the antebrachial fascia from origin to termination, but a detailed description is lacking. The relationship of the PL tendon with the antebrachial fascia was studied in 30 dissections. The PL was completely absent in six specimens (20%), whereas the PA was identified in all. Average length of the forearm was 25.5 cm (SD: 2.1 cm, range 22-29 cm), overall length of the PL muscle 26.9 cm (SD: 2.6 cm, range 22.5-31.5 cm), muscular belly 13.8 cm (SD: 3.4 cm, range 9.5-23 cm), tendon 13.1 cm (SD: 3.3 cm, range 8-15.5 cm). Proximally, the PL was situated deep to the antebrachial fascia, then in the lower third of the forearm its tendon perforated the antebrachial fascia (at 4.7 +/- 1.7 cm from the bistyloid line) moving to a suprafascial plane, inserting in the PA. The PA could be divided into two layers: the superficial one formed by longitudinal fibers and adherent to the skin, the deep one formed by transverse fibers continuous laterally with the deep fascia of the hand. The PL tendon was found to be in continuity only with the longitudinal fibers of the PA. Based on the anatomical findings, it may be suggested that the superficial part of the PA is situated in the subcutaneous planes of the palm, and that the muscle should be considered as a tensor of the superficial fascial system of the subcutaneous tissue.

“…The presence of the PLM, on the other hand, was correlated with a significant increase in risk of developing Dupuytren's disease [42], a common acquired pathological condition with fibrous degeneration of the superficial longitudinal layer of the aponeurosis and the retinacula cutis. The deep transverse layer seems to be only involved in late stages of the disease [43].…”

Abstract:The Palmaris longus muscle can be absent unilateral or bilateral in about 22.4% of human beings. The aim of this study is to investigate whether the presence of the Palmaris longus muscle is associated with an advantage to handgrip in elite tennis players compared to recreational athletes. Sixty people participated in this study, thirty elite tennis players and thirty recreational athletes. The presence of the Palmaris longus muscle was first assessed using different tests. Grip strength and fatigue resistance were measured by an electronic hand dynamometer. Proprioception was registered by the Flock of Birds electromagnetic tracking system. Three tests were set up for measuring proprioception: joint position sense, kinesthesia, and joint motion sense. Several hand movements were conducted with the aim to correctly reposition the joint angle. Results demonstrate a higher presence of the Palmaris longus muscle in elite tennis players, but this was not significant. Maximal grip strength was correlated with gender and only on the dominant side; it was also correlated with age. Fatigue resistance showed only on the non-dominant side; a significant difference in elite and recreational athletes. In proprioception there was no correlation with elite and recreational athletes or the presence of the Palmaris longus muscle.
