We report a systematic review and a proportion meta-analysis of prevalence studies evaluating the prevalence of palmaris longus agenesis (PLA) in the literature. The overall PLA rate was defined to be the primary outcome. Secondary outcomes were rates of PLA in relation to ethnicity, laterality, side, gender, age, and hand dominance. We identified 26 articles which met the inclusion criteria. Meta-analyses showed an overall PLA pooled rate of 20.25%, higher than the commonly reported overall rate of 15%. Our results also showed significantly lower pooled rates in Africans (11.3%) and East Asians (4.5%) when compared to Arab Middle Eastern population (41.7%). A subgroup analysis of the African group showed a pooled rate of 2.71%, the lowest, in the East and South East African population. The pooled rate was 26.3% among Caucasians, 26.16% among South and Southeast Asians and 34.13% among Turkish. In discordance with the literature, PLA was statistically more predominant on the right side. No significant differences in PLA rates were found for laterality, gender, the combination of gender and side or the combination of gender and laterality. The lowest rate of PLA found in East and South East African populations might be indicative of the subsequent phylogenetic degeneration of the palmaris longus muscle in modern humans after the "Out of Africa" migration.

“…According to Eric et al, the middle-age and young group showed a lower rate of the PLM presence as compared to the old group, although this difference was not significant [36,38]. In comparison, Venter et al reported no obvious trend in the PLM in the various age groups that would indicate phylogenetic degeneration of the PLM [39].…”

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.

Degenerative trends of the palmaris longus muscle in a South African population

Abstract: The literature reports that the palmaris longus muscle (PL) is only found in mammals in which the forelimbs are weight-bearing extremities. It is suggested that the function of this muscle has been taken over by the other flexors in the forearm.
