The long tendon crosses the flexor retinaculum and becomes incorporated into
palmar aponeurosis (1,2).
In 2 cases, the nerve passed through the PL fibers 1 cm and 1.5 cm proximal to its insertion into the
palmar aponeurosis. This variation could compromise the nerve during tendon graft harvesting.
The superficial
palmar aponeurosis was divided and the decompressed aneurysm was identified.
It is located just deep to
palmar aponeurosis and superficial to digital branches of the median nerve, long flexor tendons, and lumbricals.
Palmar aponeurosis, dissected longitudinally after identifying transverse carpal ligaments.
The transverse carpal ligament, which is deep to the longitudinal fibres of the superficial
palmar aponeurosis, is divided and the underlying median nerve identified.
Entrapment may occur at various locations, the most common being at the site of the A1 pulley and the
palmar aponeurosis pulley.
Dupuytren disease (DD) is a connective tissue disorder characterized by contracture involving the
palmar aponeurosis (PA).
The most radial and superficial insertion, fused with the
palmar aponeurosis, as a normal palmaris longus tendon.
These bundles occupy the triangular area in the mid palm which is called as
palmar aponeurosis. Palmaris Longus has wide insertion to skin, fascia, in the digital palm and webs.
