What is the first proximal phalanx?

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.

Where is the first proximal phalanx foot?

The proximal phalanx is the toe bone that is closest to the metatarsals.

Where is the 3rd proximal phalanx?

What do you do 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.

Which finger is the first phalanx?

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. The thumb does not have a middle phalange.

Where is the first distal phalanx?

The distal phalanges are the bones at the tips of the fingers or toes. The proximal, intermediate, and distal phalanges articulate with one another through interphalangeal articulations.

What causes proximal phalanx pain?

When any of the tissues are damaged, be it through blunt trauma or degeneration over time, a person may begin to experience pain in their proximal phalanx. As the tissues degenerate further or even rupture, the pain may become a chronic problem.

How long is the proximal phalanx?

The first proximal phalanx was the longest (28.0±2.40 mm in males and 25.8±2.21 mm in females) and the fifth distal phalanx (5.2±1.33 mm in males and 4.4±1.03 mm in females) was the shortest of all phalanges.

What is phalanges foot?

The phalanges (single: phalanx) of the feet are the tubular bones of the toes. The second to fifth toes each contain a proximal, middle and distal phalanx whereas the great toe (hallux) only contains a proximal and distal phalanx.

How long does it take for a proximal phalanx to heal?

Many stable phalanx fractures can be treated nonoperatively through close monitoring until clinical healing is noted. Proximal phalanx fractures will often be clinically healed 4 weeks status post injury, at which time it is unlikely that the fracture will displace.

How is a phalangeal fracture treated?

Most phalangeal fractures can be treated successfully with nonoperative means. Surgery is considered to treat unstable injuries, articular incongruity, concomitant soft tissue damage, or other situations in which restoration of anatomy and preservation of function are achieved only via operative stabilization.

What is a proximal phalanx fracture?

Proximal phalanx fractures often present with apex volar angulation. Interosseus muscles and lumbricals insert onto the base of the proximal phalanx and flex the proximal fragment. The flexor and extensor tendons impart a longitudinal compression force, which can shorten the phalanx and extend the distal fragment [1].

Is the thumb the first phalanx?

The thumb consists of the first metacarpal, a proximal phalanx, and a distal phalanx; one phalanx less than the fingers (Fig. 5.3). … The first CMC joint is also referred to as the trapeziometacarpal (TMC) joint since the metacarpal articulates with the trapezium.

What is 1st metacarpal?

The first metacarpal bone or the metacarpal bone of the thumb is the first bone proximal to the thumb. It is connected to the trapezium of the carpus at the first carpometacarpal joint and to the proximal thumb phalanx at the first metacarpophalangeal joint.

Where is a metatarsal?

The metatarsal bones are the long bones in your foot that connect your ankle to your toes. They also help you balance when you stand and walk. A sudden blow or severe twist of your foot, or overuse, can cause a break, or acute (sudden) fracture, in one of the bones.

What type of bone is the proximal phalanx?

The phalanges of the hand are the group of small bones that comprise the bony core of the digits (fingers) of the hand. 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.

Which metatarsal has the thickest Diaphysis?

first metatarsal bone The first metatarsal bone is the shortest of the metatarsal bones and by far the thickest and strongest of them.
