The metatarsophalangeal joints (MTP joints) are the joints between the metatarsal bones of the foot and the proximal bones (proximal phalanges) of the toes. They are analogous to the knuckles of the hand, and are consequently known as toe knuckles in common speech.

2018年11月2日 · What’s the MTP joint? An MTP joint connects one of your toes (a phalangeal bone or a phalanx) to a long bone in your foot (a metatarsal bone). There are five MTP joints on each foot — one for...

2023年11月2日 · Metatarsalgia is actually used to describe any pain in the ball of the foot—the soft, padded part on the bottom of your foot that overlies the metatarsal bones. Even so, the most common source of pain in this area is the metatarsophalangeal joint.

Metatarsophalangeal joint pain usually results from tissue changes due to aberrant foot biomechanics. Symptoms and signs include pain with walking and tenderness. Diagnosis is clinical; however, infection or systemic rheumatic diseases (eg, rheumatoid arthritis, psoriatic arthritis) may need to be excluded by testing.

2024年5月20日 · Hallux rigidus is a common foot condition characterized by pain and loss of motion of the 1st MTP joint in adults due to degenerative arthritis. Diagnosis is made with orthogonal radiographs of the foot that may show joint space narrowing and dorsal osteophytes of the 1st MTP joint.

2023年10月30日 · The metatarsophalangeal joints (MTP) are synovial joints that connect the metatarsal bones of the foot to the proximal phalanges of the toes. In these joints, the heads of metatarsal bones articulate with the corresponding bases of proximal phalanges.

In an MTP joint fusion, your foot and ankle orthopaedic surgeon removes the damaged cartilage and fixes the two bones together with screws and/or plates to enable them to grow together. This is routinely performed as an outpatient procedure.

Pain in the metatarsophalangeal joint is a common musculoskeletal condition which is usually observed when abnormal foot biomechanics and long-standing stress deteriorates the anatomical balance of foot.

Foot orthoses with metatarsal pads may help redistribute and relieve pressure from the noninflamed joints. With excess subtalar eversion or when the feet are highly arched, an orthotic that corrects these abnormal alignments should be prescribed.

Metatarsophalangeal (MTP) joint sprain (turf toe) is a sprain of the great toe plantar ligament complex. Pain occurs with active and passive motion of the swollen joint. X-rays are needed to rule out fracture. Treatment is with buddy taping, analgesics, and usually physical therapy to help prevent chronic stiffness.
