Abnormal metatarsal morphology Midfoot arthritis 2025-09-01T10:45:00Z AP, oblique, or lateral view x-ray of the foot showing radiographic evidence of osteoarthritis in the midfoot (tarsometatarsal (TMT) joints, naviculocuneiform joint, intercuneiform joints, and/or metatarsal cuneiform joints), such as joint space narrowing, subchondral sclerosis, subchondral cysts, and/or osteophyte formation in the tibiotalar joint. Midfoot includes Tarso-metatarsal (TMT) joints and naviculo-cuneiform joints (NCJ). Talo-navicular joint (TNJ) and calcaneocuboid joint (CCJ) are considered to be part of hindfoot along with sub-talar joint. Tarso-metatarsal joints are divided into three columns anatomically: the medial column (First Tarsometatarsal joint), the middle column (second and third TMT joints) and the lateral column (Fourth and Fifth TMT or Metatarsocuboid joints). TMT joints are collectively known as Lisfranc joints as well.
