Palmar Aponeurosis

The wrist is crossed by flexor and extensor tendons which course along its ventral and dorsal aspects respectively. Among them, nine flexor tendons and nine extensor tendons move toward the fingers without any attachment to the carpal bones two primary wrist flexors and three wrist extensors insert onto the distal carpal row and the metacarpals and one tendon, the palmaris longus tendon, attaches to the transverse carpal ligament and to the palmar aponeurosis. 

After exiting the carpal tunnel, the tendons of the flexor digitorum superficialis and profundus pass deep to the palmar aponeurosis and enter the osteo-fibrous digital tunnels. In each finger, the two ten-...

Plantar fibromatosis is a benign condition characterized by focal nodular enlargement of the plantar aponeurosis due to local proliferation of fibrous tissue. Its origin is unknown and it was first described by Dupuytren in 1839, who noted an association with palmar fibromatosis (Dupuytren 1839). This condition is also known as Ledderhose disease after the eponymous doctor who reported more than 50 cases in 1897 (Ledderhose 1897). Patients present with...
