Metatarsophalangeal articulations are the joints between the metatarsal bones of the foot (the long bones in the center of the foot) and the proximal bones (phalanges) of the toes. They are elliptical (round), which makes them condyloid joints.
Movement allowed by metatarsophalangeal articulations includes abduction, adduction, circumduction, extension and flexion.
Metatarsophalangeal articulations can experience pain and conditions such as flexor plate tears, joint cartilage destruction (osteoarthritis), capsular impingement and synovial impingement. The second metatarsophalangeal articulation is the joint most commonly affected by these conditions. Usually, foot orthoses with metatarsal pads can help alleviate any discomfort.
Early morning metatarsophalangeal joint pain and stiffness can be an early indicator of rheumatoid arthritis.
