What is MCP and PIP?
The joints involved most frequently are the proximal interphalangeal (PIP) and metacarpophalangeal (MCP) joints of the hands, the wrists, and small joints of the feet including the metatarsophalangeal (MTP) joints. The shoulders, elbows, knees, and ankles are also affected in many patients.
What does PIP and DIP mean?
The rest of the toes each have three phalanx bones (proximal, middle, and distal phalanges), so they have two interphalangeal joints: the proximal interphalangeal joint between the proximal and middle phalanges (abbreviated “PIP joint”) and the distal interphalangeal joint between the middle and distal phalanges ( …
What does PIP and DIP stand for in joints of the fingers?
The proximal interphalangeal (P.I.P.) and the distal interphalangeal (D.I.P.) Whereas the medial bundle of the extensor assembly runs over the dorsum of the proximal interphalangeal joint, the two lateral bundles of both sides pass the dorso-lateral aspect of this joint, to fuse more distally into one terminal tendon.

What is MCP joint?
The metacarpophalangeal joint or MP joint, also known as the first knuckle, is the large joint in the hand where the finger bones meet the hand bones. The MCP joint acts as a hinge joint and is vital during gripping and pinching. When arthritis affects the MP joint, the condition is called MP joint arthritis.
What does MCP joint stand for?

What does MCP stand for in anatomy?
The metacarpophalangeal (MCP) joints are located where the hand’s fingers and thumb meet the palm. They are commonly known as large knuckles.
Where are the PIP and DIP joints?
The DIP joint in the finger is located at the tip of the finger, just before the finger nail starts.
