Being a hinge joint, the joint’s articular surface and soft tissue do not permit any lateral movement.

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 is the metacarpophalangeal 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 are MCP and IP joints?
Metacarpophalangeal ligaments and interphalangeal ligaments. The fingers (index through small fingers) are composed of 3 bones each and are all associated with a single metacarpal. Thus, 3 joints per finger exist, all of which have significant motion and require stabilization to prevent subluxation and dislocation.
What are distal joints?
Distal interphalangeal joints are the articulations between the phalanges of the hand or foot. This term therefore includes: Interphalangeal articulations of hand. Interphalangeal articulations of foot.
What is thumb joint called?
The thumb basal joint, also known as the carpometacarpal (CMC) joint, is a specialized saddle-shaped joint that is formed by a small wrist bone (trapezium) and the first of the three bones in the thumb (metacarpal).
What is the first finger joint called?
proximal interphalangeal joint
The first joint, closest to the knuckle joint, is the proximal interphalangeal joint or PIP joint. The second joint nearer the end of the finger is called the distal interphalangeal joint, or DIP joint. The thumb in the human body only has 2 phalanges and one interphalangeal joint.
What does MP joint stand for?
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.
Where is the PIP joint in the hand?

What is a PIP joint sprain?
Injury to the PIP joint is one of the most common injuries the hand sustains and can occur as a sprain or a complete tear of the ligament – resultant of an activity that causes the joint to hyperextend – as well as a dislocation. A sprain represents a ligament that has been stretched and partially torn.
