The interphalangeal joints of the hand are the hinge joints between the phalanges of the fingers that provide flexion towards the palm of the hand . There are two sets in each finger (except in the thumb, which has only one joint): Anatomically, the proximal and distal interphalangeal joints are very similar. There are some minor differences in ...
Function. The DIP, PIP and MCP joints of the hand: - D istal I nter P halangeal - P roximal I nter P halangeal - M eta C arpo P halangeal. The function of the interphalangeal joints of the hand to permit fine motor movements in the digits. To accomplish this, these joints facilitate movement within only one degree of freedom: flexion - extension.

Nov 9, 2023 · 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. Its uniaxial nature allows for a good range of movement but only in one ...
Dec 20, 2023 · The proximal interphalangeal joint (PIPJ) refers to the articulation between the proximal and middle phalanx in the hand. It is present in all digits except the thumb. It is a synovial hinge joint which permits flexion and extension in center of the fingers, contributing to fine motor control.
The hand contains a number of joints that allow complex actions, such as manipulating, gripping and grasping objects. Optimal hand function requires adequate strength, sensation, range of motion, and dexterity. When one or more of these components are injured or impaired, an individual's participation in daily activities may be significantly ...
