Aim: This study aimed to evaluate the presence of the Palmaris Longus
Tendon (PLT) and the relationship between the Flexor Retinacular
Ligament (FRL) and the Palmar Aponeurosis (PA) of the hand.
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.
