Abstract:
The transverse fascicular fibers and paratendinous bands of the palmar aponeurosis are positioned at the proximal margin of the flexor tendon sheath. These anatomic structures form a tunnel around the flexor tendon and appear to function as a palmar aponeurosis pulley in conjunction with the first and second annular pulleys of the digital flexor mechanism.
