2023年11月2日 · Between the heads of the metatarsal bones and the bottoms of the proximal phalanges (your toe bones) are the metatarsophalangeal joints. In other words, metatarsophalangeal joints connect your toe bones to your foot bones. These joints are surrounded by a thin joint capsule and have ligaments that support them.

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 · There are five MTP joints on each foot — one for each toe — but the term “MTP joint” is often used to refer only to the big toe joint. This is the MTP joint that most frequently causes a...

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.

The great toe MTPJ is one of the smallest joints in which to perform arthroscopy. The MTPJ is a highly congruent joint, minimizing the ability to “drive through” the joint. Meticulous micromotion is needed to prevent arthroscopic pistoning and iatrogenic injury.

2021年3月12日 · Great toe metatarsophalangeal joint (MTPJ) arthroscopy was first described as a viable technique for a multitude of first MTPJ pathologies in the early 1970s; however, with improving arthroscopic technique and technology, these indications will continue to expand.

The metatarsophalangeal joint (or MTP joint) is the first joint that connects the toe to the foot. The ball of the foot is formed by the MTP joints. The second joint is the proximal interphalangeal joint (or PIP joint), and the last is the distal interphalangeal joint (or DIP joint).

A hammer toe or contracted toe is a deformity of the proximal interphalangeal joint of the second, third, or fourth toe causing it to be permanently bent, resembling a hammer. Mallet toe is a similar condition affecting the distal interphalangeal joint.

2019年5月13日 · The big toe has two joints, but the one most vulnerable to problems is the metatarsophalangeal (MTP) joint. It connects the first long bone (metatarsal) in the forefoot to the first bone of the big toe (phalanx).

We propose a simple technique with illustrations of the operating room setup and procedural steps to perform a dorsal cheilectomy in those with early-stage hallux rigidus using great toe MTPJ arthroscopy and a minimally invasive surgical …
