What is the DIP joint of the toe?

The metatarsal phalangeal joint (MTP joint) is the first joint that connects the toe to the foot. The second is the proximal interphalangeal joint (PIP joint), and the last is the distal interphalangeal joint (DIP joint). A joint capsule made of ligaments surrounds each joint and holds the bones together.

What type of joint is the proximal interphalangeal joint?

hinge jointThe proximal interphalangeal (PIP) joints of the fingers are extremely important for gripping things with hands, more specifically, what is called the ‘power’ grip. Being a hinge joint, the joint’s articular surface and soft tissue do not permit any lateral movement.

What kind of joint are toes?

The big toe has the metatarsophalangeal joint and one interphalangeal joint. A layer of cartilage covers the surfaces of the joints where the bones meet which allows them to glide smoothly with each other as they move. A thin membrane called the synovium encloses the joint and secretes a fluid to lubricate them.

Why does the thumb only have 2 joints?

Thumbs only have two bones, so they’re obviously shorter, and they play a very important role that no other finger can claim; thanks to their unique saddle-like joint shape, and a little muscle known as the abductor pollicis brevis, you can bend and stretch your thumbs opposite your fingers to grip things.

What is a DIP joint on the finger?

The DIP joint is the first knuckle from the top of the finger. It connects the distal phalanx and middle phalanx, which are the two bones at the tip of the finger. Experiencing DIP joint pain is often a sign of a type of arthritis, such as osteoarthritis or psoriatic arthritis.
