Common flexor sheath of hand

Common flexor sheath of hand
The mucous sheaths of the tendons on the front of the wrist and digits. (Common sheath of Flexores digitorum subliminis and profundus labeled at center right.)
Latin	vagina communis tendinum musculorum flexorum manus, vagina communis musculorum flexorum
Gray's	subject #126 457

The common synovial sheath for the flexor tendons or the ulnar bursa^[1] is a synovial sheath in the carpal tunnel.

It contains tendons of the flexor digitorum superficialis and the flexor digitorum profundus, but not the flexor pollicis longus.^[2]

The sheath which surrounds the Flexores digitorum extends downward about half-way along the metacarpal bones, where it ends in blind diverticula around the tendons to the index, middle, and ring fingers. It is prolonged on the tendons to the little finger and usually communicates with the mucous sheath of these tendons.
