Where is the head of the phalanx?
distal extremity
The head of phalanx is the distal extremity. It presentson the first and second row (except for the toe) a trochlear surface for articulation with the second phalanx.
What does proximal phalanx mean?
The proximal phalanges (hand) are the bones that are found at the bottom of the finger. They are named proximal because they are the closest phalanges to the metacarpals. There are fourteen phalanges in each hand.
What is the base of proximal phalanx?
The base end of the proximal phalanx is concave in shape where it connects to the metatarsal bone. The head of the proximal phalanx connects to the intermediate phalanx in a trochlear fashion that allows for articulation.
What is structure of head of proximal and middle phalanges?
In the foot, the proximal phalanges have a body that is compressed from side to side, convex above, and concave below. The base is concave, and the head presents a trochlear surface for articulation with the second phalanx. The middle are remarkably small and short, but rather broader than the proximal.
Where is the proximal phalanx of toe?
The proximal phalanx is the toe bone that is closest to the metatarsals. Because it is the longest of the toe bones, it is the most likely to fracture.
Where is the proximal phalanx of hand?
The proximal phalanx of the fingers is the proximal, or first bone, in the fingers when counting from the hand to the tip of the finger. There are three phalanges in each finger. The proximal phalanx is the largest of the three bones in each finger; it has joints with the metacarpal and with the middle phalanx.
How do you treat a broken proximal phalanx?
Proximal phalanx fracture – undisplaced Your fracture can be treated with splinting, taping or casting (or a combination of all three of these). Generally a cast is only used for treating phalangeal fractures for children or individuals who will not be able to keep their fingers safely immobilised with a splint.
What is proximal phalanx fracture?
Proximal phalanx fractures can be epiphyseal or shaft fractures and can be intra-articular or extra-articular. They are most often the result of forced rotation, hyperextension or direct trauma 2.
What is structure of head of distal phalanx?
The head, which represents the expanded and rounded distal part. It has a pulley-shaped articular surface that articulates with the base of the middle phalanx to form the proximal interphalangeal (PIP) joint. The heads consist of smooth grooves, especially on the palmar aspects.
Where is the proximal phalanx located?
What is the tip of the finger called?
distal phalanx
Anatomy. The fingertip is considered the region of the distal phalanx distal to the insertion of the flexor and extensor tendon. It includes the perionychium, nail plate, and volar pad.
How do you fix a broken proximal phalanx?
Your fracture can be treated with splinting, taping or casting (or a combination of all three of these). Generally a cast is only used for treating phalangeal fractures for children or individuals who will not be able to keep their fingers safely immobilised with a splint.
Where is the first proximal phalanx?
Proximal Phalanges The proximal phalanx of the fingers is the proximal, or first bone, in the fingers when counting from the hand to the tip of the finger. There are three phalanges in each finger.
What is 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. On the tip of the phalanx is a bulbous tuft of bone that helps give the finger its rounded appearance.
