Finger Anatomy Joints

The index middle ring and fifth digits have proximal middle and distal phalanges and three hinged joints. We present our 3 t mri protocol using a dedicated hand and wrist coil and review normal mri anatomy of the fingers.

Finger Proximal Interphalangeal Pip Joint Dislocation

Anatomy of the fingers.

Finger anatomy joints. The thumb has two knuckle joints. Interphalangeal joints of the hand. Proximal interphalangeal joints pij or pip.

Proximal interphalangeal joint pip the joint in the middle of the finger. Interphalangeal joint ip the thumb digit has only two phalanges bones so it only has one joint. The finger joints the joints of the fingers include the metacarpophalangeal joints and the interphalangeal joints.

The thumb has a distal and proximal phalanx as well as an interphalangeal and mcp joint. There are four joints in each finger totaling 20 joints in each hand. The human finger is mainly a bony structure with multiple joints giving it strength and flexibility.

Instead it is contained within a single structure the hand. Distal interphalangeal dip proximal interphalangeal pip and metacarpophalangeal mcp. Metacarpophalangeal joint mcp the joint at the base of the finger.

Finger joints knuckles each finger contains 3 joints more commonly known as knuckles. Each thumb has two joints. There are two sets in each finger except in the thumb which has only one joint.

The dip joint is located at the tip of the finger just before the finger nail starts. The thumb interphalangeal ip joint is similar to the distal interphalangeal dip joint in the fingers. The largest joint of each finger lies between the finger and the hand.

Basic anatomy of the finger. Distal interphalangeal joint dip. A digit includes the hand bones but these bones are not separated into individual appendages like a finger.

The ip joint in thumb is located at the tip of the finger just before the fingernail starts. Arthritis can develop at this joint and it is also commonly fractured. Joints are formed wherever two or more of these bones meet.

The knuckles are joints formed by the bones of the fingers and are commonly injured or dislocated with trauma to the hand. Theyre all synovial joints with synovial membranes and fibrous joint capsules. The first and largest knuckle is the junction between the hand and the fingers the metacarpophalangeal joint mcp.

Each of the fingers has three joints. With high resolution 3 t mri the complex anatomy of the fingers can be imaged in exquisite detail to provide an accurate diagnosis of clinically important ligament and tendon injuries. This first joint at the base of the finger is called the metacarpophalangeal joint mcp.

The small ringer middle and index fingers all have the same four joints. Distal interphalangeal joint dip the joint closest to the fingertip. It works like a hinge when you straighten your fingers and thumb.

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.
