Method: 62 voluntary subjects (31 female, 31 male students and personnel from the Inonu University, at the average age 28.38 ± 6.86 years ranging from 19 to 48 years) took part in this study using ultrasound. Result: Significant differences were found in the PA p-m-d diameters of subjects between with and without PLT bilaterally, on the right and the left hand (p<0.05), whereas there was no meaningful difference considering FRL diameters (p>0.05). Furthermore, this ultrasonographic assessment revealed the continuity of collagen bunches of the PL tendon up to FRL, but not PA. Conclusion: Although not demonstrated by ultrasonography here, the increased thickness of the PA in subjects with a PLT supports the findings in the literature in which the structural continuity between the PLT and PA have been stressed.trinfo:eu-repo/semantics/openAccessFlexor retinacular ligamentPalmar aponeurosisPalmaris longus tendonUltrasonographyArticle7216116610.29333/ejgm/828442-s2.0-78650220026N/A
