In this study, we have obtained high resolution, high
field (11.7 Tesla) Magnetic Resonance (MR) images of the
pulleys of the flexor tendons of cadaveric toe
specimens. Although the anatomy of the pulley system has
been described in one previous article, there have been
no previous MRI descriptions of the pulley system of the
toes published in the imaging literature. Understanding
of toe pulley anatomy is likely to be of benefit in
diagnosing tenosynovitis and recognizing the effects of
trauma. Detailed anatomy of the pulley system of the
flexor tendons allows similarities and differences
between the pulley system in the foot and that in the
hand to be identified. The A5 pulley, which has
previously been described only in the 2nd to 5th
fingers, was also present in the lesser toes. The MR
visualization of the pulleys included features not seen
or reported in descriptions of the finger pulleys such
as the internal structure and magic angle effects.
Validation was performed by direct inspection of
anatomic specimens.
