What type of joints are the Pips?
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….Interphalangeal joints of the hand.

How many PIP joints are in the hand?
The bones in our fingers and thumb are called phalanges. 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.
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 extends PIP joint?
Extension of the PIP joint is primarily a function of the extrinsic extensor (EDC); the two lateral bands have a greater role for PIP joint extension than the central slip alone because the two lateral bands are composed of the EDC, interosseous, and lumbricals all together.
What joints are in the hand?
The joints in the hand are joints found at the distal end of the upper limb. The joints are: In the wrist there is the radiocarpal joint between the radius and carpus. Between the carpal bones are the intercarpal articulations and the midcarpal joint….Joints of hand.

What are the names of the joints in the hand?
Each of the fingers has three joints:
- metacarpophalangeal joint (MCP) – the joint at the base of the finger.
- proximal interphalangeal joint (PIP) – the joint in the middle of the finger.
- distal interphalangeal joint (DIP) – the joint closest to the fingertip.
Why does PIP joint hurt?
PIP related injuries are typically caused by acute trauma such as sudden overextension of the joint between the proximal phalanx and metacarpal bones. Even though most of the causal injuries are sudden, a person may only begin to experience the symptoms of injury over time.
How do you fix a PIP joint?
Available treatment options include immobilization, protected motion, traction, open reduction and internal fixation, buttress reconstruction, joint arthroplasty, or arthrodesis. By principle, stable PIP joint fracture dislocations can be treated non-surgically if closed reduction can restore a normal AOM.
