AN ANATOMICAL STUDY OF THE TARSAL TUNNEL USING LOW-PRESSURE COMPARTMENTAL INFUSION

The anatomy of the tarsal tunnel is demonstrated using a low-pressure compartmental infusion technique. This is done by infusing colored rad iopaque contrast material into three fresh cadaveric specimens. Thin s ection photography and computed tomography are then used to identify t he boundaries and contents of the tarsal tunnel as it traverses the an kle, hindfoot, and midfoot. The tarsal tunnel is shown to communicate proximally with the deep posterior compartment of the leg and distally with the intermediate compartment of the forefoot. The relationships of the structures contained within the tarsal tunnel are shown in deta il.
