What are the 3 bones of the phalanges?

Phalanges: The bones of the fingers and of the toes. There are generally three phalanges (distal, middle, proximal) for each digit except the thumbs and large toes. The singular of phalanges is phalanx.

What kind of joint is found between the proximal and distal phalanges of the thumb?

Interphalangeal Joint (IP) The thumb digit has only two phalanges (bones) so it only has one joint. The thumb interphalangeal (IP) joint is similar to the distal interphalangeal (DIP) joint in the fingers.

How can you distinguish between proximal intermediate and distal phalanges?

The key feature to pay attention to is the proximal articular surface. Proximal phalanges have only a single concave articular facet (for the rounded head of the metacarpals or metatarsals), while intermediate and distal phalanges have concave and bilobate distal articulations.

Do all of the fingers have a proximal intermediate and distal phalanx?

Three phalanges are present on each finger and toe, with the exception of the thumb and large toe, which possess only two. The middle and far phalanges of the fourth and fifth toes are often fused together (symphalangism).

What are phalanges bones?

Phalanges. The 14 bones that are found in the fingers of each hand and also in the toes of each foot. Each finger has 3 phalanges (the distal, middle, and proximal); the thumb only has 2.

What is the distal joint in a finger?

The distal interphalangeal joint connects the bones at the tips of the fingers. Many people with arthritis experience pain at this location. People who experience distal interphalangeal (DIP) joint pain may also experience other symptoms, depending on which type of arthritis they have.

What joint is between the phalanges?

interphalangeal joints
The joints between the phalanges are the interphalangeal joints – proximal and distal.

What are the three parts of your fingers called?

The three bones in each finger are named according to their relationship to the palm of the hand. The first bone, closest to the palm, is the proximal phalange; the second bone is the middle phalange; and the smallest and farthest from the hand is the distal phalange.

What is the distal phalanx?

The distal phalanx of the finger is the distal or third of the three bones in each finger when counting from the hand to the tip of the finger. The distal phalanx has a joint just with the middle phalanx. The distal phalanx is also important for supporting the fingernail.

What is a proximal phalanx fracture?

The most common hand fracture in the pediatric population is a fracture of the… distal phalanx. metacarpal. middle phalanx. proximal phalanx.

What is phalanges bone?

Phalanges. The 14 bones that are found in the fingers of each hand and also in the toes of each foot. Each finger has 3 phalanges (the distal, middle, and proximal); the thumb only has 2. Metacarpal bones.
