What is the proximal interphalangeal joint?

The 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.

Where is the proximal interphalangeal joint?

There are two sets in each finger (except in the thumb, which has only one joint): “proximal interphalangeal joints” (PIJ or PIP), those between the first (also called proximal) and second (intermediate) phalanges.

What type of joint is the proximal interphalangeal joint?

Synovial hinge joint
Since the first digit only has a proximal and distal phalanx, the joint between them is simply known as the interphalangeal joint of the thumb….Interphalangeal joints of the hand.

How long does it take for a PIP joint to heal?

After approximately three to four weeks, the joint should heal enough to remove the splint and begin strengthening exercises. Our Physical Therapist will develop a personalized exercise program to help you recover the range-of-motion and strength in your fingers.

What is a proximal joint?

Proximal interphalangeal joints” (PIJ or PIPJ), those between the first (also called proximal) Distal interphalangeal joints” (DIJ or DIPJ), those between the second (intermediate) third (distal) phalanges.

What does Pip mean anatomy?

proximal interphalangeal
The proximal interphalangeal (PIP) joints are commonly known as the middle knuckles of the fingers. The thumb does not have a PIP joint.

What are proximal joints?

How many interphalangeal joints are in a hand?

Each finger has 3 phalanges separated by two interphalangeal joints, except for the thumb, which only has 2 phalanges and one interphalangeal joint. The first joint close to the knuckle joint is called the proximal interphalangeal joint or PIP joint.

Is the proximal interphalangeal joint a hinge joint?

Proximal interphalangeal (PIP) joint injury PIP joint injuries are very common in athletes. The joint is a hinge, which allows for flexion and extension, with significant lateral stability provided by the bony architecture and the proper and accessory collateral ligaments.

How many interphalangeal joints are in the body?

Interphalangeal Joint (IP) The thumb digit has only two phalanges (bones) so it only has one joint.

What is the type of joint formed by the phalanges?

These joints are of the condyloid kind, formed by the reception of the rounded heads of the metacarpal bones into shallow cavities on the proximal ends of the proximal phalanges. Being condyloid, they allow the movements of flexion, extension, abduction, adduction and circumduction at the joint.

Is the interphalangeal a saddle joint?

The distal interphalangeal joints are saddle joints, formed by the distal trochlea of the medial phalanges and the articulating fossae of the distal phalanxes. In dogs, the distal interphalangeal joints may present a small, spheroidal, sesamoid cartilage, located on the palmar side of the joint capsule.

What is DIP joint pain?

Painful movement of the joints near the tips of your fingers or toes, or your distal interphalangeal joints, may result from injuries, rheumatoid arthritis and other conditions. Your distal interphalangeal joints, or DIP joints, are the joints found near the tips of your fingers and toes.

What is distal thumb joint?

In anatomy, distal is a term of relative location, referring to a structure that is farthest from the trunk of the body versus one that is nearest the body, or proximal. As the thumb has only two phalanges rather than three, there is no distinction between a proximal and distal interphalangeal joint in this digit.
