Radiological aspects of the tarsometatarsal joints.

Considerable difficulty may be encountered in evaluation of the disrupted tarsometatarsal joint complex as seen in variations of fracture dislocations of the Lisfranc's joint. This report points out constant relationships between the tarsal and metatarsal bones as seen on the standard anteroposterior and medial oblique views. Awareness of these constant radiological relationships can help the operating surgeon reconstruct the normal anatomic alignment.
