The normal DDFT changes in its shape and cross-sectional area from proximally to distally, but it is usually bilaterally symmetrical. A normal DDFT is uniform in its echogenicity, and its margins are clearly defined. At the site at which the ALDDFT merges with the DDFT there may be a relatively hypoechogenic region, especially in the hindlimbs. This is a normal variant. Hypoechoic artifacts are induced readily in the distal fetlock and pastern regions if the ultrasound transducer is not perpendicular to the tendon, and in these regions evaluating the SDFT and DDFT simultaneously is difficult. Echogenic synovial plicae (mesotendon) extend medially and laterally from the DDFT to the DFTS wall in the proximal recess of the DFTS (Figure 70-2, A). These are seen much more obviously when the tendon sheath is distended and should not be mistaken for marginal tears or adhesions. With chronic tenosynovitis, these plicae may become thickened. Distal to the fetlock is an echogenic palmar (plantar) synovial fold that should not be confused with an adhesion (see Figure 70-2, B
