The structure of the digital fibrous flexor sheath was examined by dissection and histology. The presence of a specific system of named fibrous tissue bands, forming annular and cruciate pulleys, was noted confirming details which are well established in the surgical literature although not detailed by the anatomical texts. These pulleys were linked by thin parts of the sheath. When the inner aspect of the sheath was examined, it was found that it was not a continuous smooth surface, as depicted in both anatomical and surgical texts. The thin parts of the sheath often overlapped the free edges of the pulleys before attaching to their superficial aspects, so that the pulleys possessed free edges within the sheath. Forty eight cadaveric fingers were examined in order to determine the frequency of occurrence and sizes of these overlaps. The largest and most frequent overlap was found at the distal end of the A2 pulley (which attaches to the proximal phalanx).
