The metatarsophalangeal joints (MTP joints) are the joints between the metatarsal bones of the foot and the proximal bones (proximal phalanges) of the toes. Metatarsophalangeal joint pain usually results from tissue changes due to aberrant foot biomechanics. An MTP joint connects one of your toes (a phalangeal bone or a phalanx) to a long bone in your foot (a metatarsal bone). Metatarsophalangeal (MTP) joints are articulations between the metatarsals and the proximal phalanges. Mechanical disorders of MTP joint: Metatarsophalangeal joint pain (also referred to as metatarsalgia) can also be due to surface misalignment of connective tissue. The metatarsophalangeal joints allow additional dorsiflexion and plantar flexion of the foot with the first joint allowing 80 to 90 degrees of dorsiflexion with the.
