dorsally where it is adjacent to the DDFT (A and B). The DDFT is correspond to the gross section slice plane that is close to the
rounded in shape. The ICL is located dorsal to the DDFT with the carpometacarpal joint. At this level, the ICL is the only structure
carpal sheath visualized as an anechoic triangular structure apparent dorsal to the DDFT. The median artery and large
between these two structures (B). The SL is located dorsal to the metacarpal vein are prominent on the medial aspect of the DDFT.
