“…This is comparable to other studies in Caucasian populations, which report a rate of absence of around 15-21% 10–1219. If we compare the deficiency of the FDS in the little finger with absent PL, the overall incidence is 4.15%, and it is statistically significant, while the sexwise distribution of weak FDS with absent PL was statistically significant in males and in females it was statistically insignificant.…”

“…First, full and free range of motion of the PIPJ of both little fingers was confirmed. FDS function in the little finger was assessed by standard and modified tests and divided into normal or weak FDS function 10–13. Normal function was defined as the ability to flex the PIPJ of the little finger >90° with the PIPJ of the other fingers extended or when the ring finger PIPJ was also allowed to flex simultaneously.…”

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.

“…Among Nigerian populace, 31.25% subjects showed absence of PL, out of which 12.5% was recorded as unilateral absence while and 18.75% subjects recorded as bilateral absence of PL [16,17]. While many previous studies have conflicted with respect to the frequency of PL absence in connection to body side and gender [18][19][20].…”

“…In an Indian study, significant results were obtained showing the FDS weakness in the people who had PL absence, and, in addition, it was found with a more tendency towards the male population [24]. Baker et al, in 1981, found that the absence of the PL and the variation of the FDS showed independence results [25]. Fortunately, the PL absence and the FDS variations do not affect the hand function.…”

Introduction. Congenital Palmaris Longus (PL) absence was found in 15%–20.25% of population globally. This condition and Flexor Digitorum Superficialis (FDS) tendon absence in little finger are not known in Saudi Arabia. We studied prevalence of PL and FDS agenesis in Saudi Arabian population. Methods. A random cross-sectional study was carried out after an ethical approval in the Riyadh universities. Schaeffer's test was used to examine PL absence. The Modified test was used to examine FDS absence. Data was analyzed using Microsoft Excel and the SPSS Software version 22. Results. The volunteers, 331, males 164 (49.5%) and females 167 (50.5%), mean age of 23 (SD ± 5.3), showed right hand dominance in 294 (88.8%) and bilateral absence of PL and FDS in 15.1% and 14.8%, respectively. The hand dominance showed no significant relation between PL and FDS absence, p value = 0.788, 0.835, respectively. Generally, we found a weak correlation between absence of the PL and FDS, p value ≥ 0.595. Conclusion. The bilateral absence of PL and FDS was found as 15.1% and 14.8%, respectively. Variation of the FDS tendon absence was an independent entity for the PL absence. The dominance of hands was not related to the tested variables found in PL and FDS agenesis.
