File 1 Mendeley Supplemental Figure 1 Supplemental Figure 1A: Youthful appearance of the dorsum of the hand in a 25-year-old female showing supple soft tissues obscuring the subcutaneous structures. Supplemental Figure 1B: Aged appearance of the dorsum of the hand in a 48-year-old male showing dominant wrinkles, prominent tendons, bulging veins, and volumetric loss in the sunken thenar and hypothenar eminence. Supplemental Figure 1C: Sonographic examination of the dorsum of the hand in a 25-year-old female. Supplemental Figure 1D: Sonographic examination of the dorsum of the hand in a 48-year-old male, showing volumetric loss in the three fatty laminae, especially the dorsal intermediate laminae.
