What is the proximal phalanx of a finger?
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.
What is the proximal phalanx?
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.
How long does it take for a proximal phalanx fracture to heal?
Proximal phalanx fractures will often be clinically healed 4 weeks status post injury, at which time it is unlikely that the fracture will displace. A method of qualifying this is lack of discomfort when direct manual pressure is applied to the injured bone.
Where is proximal phalanx located?
In medical lingo, a proximal phalanx is the bone in each toe closest to the metatarsal bone that connects to the intermediate phalanx bone.
What is a proximal phalanx fracture?
Proximal phalangeal fractures are relatively common. Injury may result from a direct perpendicular force, a rotary force, or hyperextension of the finger. Proximal phalanx fractures can be the most disabling fracture of the hand because of the potential for damage of the extensor and flexor tendons.
What is the function of phalanx?
Each finger contains all three types of phalanx except for the big toe and thumb, which are missing the middle phalanx. The phalanges function to allow us to grip and hold onto objects.
Is proximal phalanx a long bone?
Even though the phalanges are small in size, they are classified as long bones because of their structural characteristics; each phalanx consists of a shaft, distal head and a proximal base.
Do you need a cast for a proximal phalanx fracture?
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.
How do you manage a proximal phalanx fracture?
Treatment consists of digital block anesthesia followed by one gentle attempt at closed reduction by hyperextending the distal phalanx and then sliding the base of the distal phalanx over the head of the proximal phalanx. Rotational force may be necessary. If unsuccessful, open reduction is required.
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.
Does a fractured finger need a cast?
Your doctor will put your broken bone back into place, usually without surgery. You will get a splint or cast to hold your finger straight and protect it from further injury while it heals. Sometimes your doctor may splint the fingers next to the fractured one to provide additional support.
What is phalanx fracture?
A phalanx is any bone of the fingers or toes. A phalanx fracture is a crack or complete break in one of these bones. A phalanx fracture can happen when your finger or toe is hit, pulled, jammed, crushed, or twisted. It is also possible for a tumor or cyst to weaken the bone, causing it to break easily when injured.
