Post-traumatic Arthritis of the Tarsometatarsal Joint Complex: A Case Report.

Tarsometatarsal (TMT) arthritis is characterized by instability and pain in the foot. The commonest cause is post-traumatic arthritis. A Lisfranc injury involves the articulation between the medial cuneiform and the base of the second metatarsal, which is considered a keystone to midfoot integrity. Neglected or undertreated injury to the Lisfranc joint complex leads to secondary arthritis and significant disability. We present a case of a young male patient with a two-year-old neglected Lisfranc joint injury and secondary osteoarthritis of the first, second, and fourth TMT joints, which we treated surgically with arthrodesis using screws, with a good functional outcome on final follow-up.
