What is the first phalanx?

What is the first 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.

What is the 1st distal phalanx?

The distal phalanges (foot) are located at the end of each toe. Three phalangeal bones make up each digit, articulating with each other at bending joints. The distal phalanges come at the end, right below the toenail.

Where is the 1st proximal phalanx?

The proximal phalanx is the phalanx (toe bone) closest to the leg. The image shows a diagram of where these bones lie in the foot—the midpoint of the proximal phalanges being where to the toes branch off from the main body of the foot.

How many middle phalanges are there?

Middle phalanges There are four middle (intermediate) phalanges in each hand because the thumb is missing one. They have a similar structure to the proximal ones, consisting of a base, body and head.

Where is the base of the middle phalanx?

The base of the middle phalanx in digits 2 to 5 articulates with the head of the respective proximal phalanx to form the proximal interphalangeal (PIP) joint.

What is the second phalanx?

The phalanges (single: phalanx) of the hands are the tubular bones of the fingers and thumb. The second to fifth fingers each contain a proximal, middle and distal phalanx whereas the thumb only contains a proximal and distal phalanx.

Where is P1 on the finger?

proximal phalanges
The hand is consequently composed of 14 phalanges including: Five proximal phalanges (P1) Four middle phalanges (P2) for the long fingers. Five distal phalanges (P3/P2) for the thumb.

What is the 1st proximal phalanx in the foot?

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. A fractured toe may become swollen, tender and discolored. If the bone is out of place, your toe will appear deformed.

Where is the middle phalanges?

As the name suggests, the middle phalanges are the middle row of finger bones, located between the proximal and the distal phalanges.

How are middle phalanges numbered?

The digits have a universal labeling system using the anatomical position of the hand (palm facing anteriorly) as reference. Going from lateral to medial, they are named thumb (digit 1), index finger (digit 2), middle finger (digit 3), ring finger (digit 4) and little finger (digit 5).

How do you fix a broken middle phalanx?

Middle phalanx fracture – undisplaced Your fracture will be treated with splinting, taping or casting (or a combination of all three). Generally a cast is only used for treating middle phalangeal fractures if the patient is a child or someone who will not be able to manage with a splint.

What lacks a middle phalanx?

The thumb and large toe do not possess a middle phalanx. The distal phalanges are the bones at the tips of the fingers or toes.

What is P1 and P2 in hand?

Each finger is divided into three phalanges except for the thumb with only two phalanges. The hand is consequently composed of 14 phalanges including: Five proximal phalanges (P1) Four middle phalanges (P2) for the long fingers.

What is a P1 fracture?

Fractures of the first/proximal phalanx (P1) may occur in any type of horse used for performance. They may be small osteochondral “chip” fractures along the dorsal margin of the proximal joint surface, sagittal (complete or incomplete), or comminuted.

What is middle phalanx?

middle phalanx. The phalanx of the finger or toe that lies between between the distal and the proximal phalanges.

What is the intermediate phalanx of the finger or toe?

The phalanx of the finger or toe that lies between between the distal and the proximal phalanges. The first finger (thumb) and hallux (big toe) do not contain middle phalanges. When there are three phalanges, the phalanx intermediate between distal and proximal phalanges.

How do you name a phalanx?

A phalanx is named according to whether is are proximal, middle, or distal and its associated finger or toe. The proximal phalanges are those that are closest to the hand or foot.

What is a proximal phalanx called?

A phalanx is named according to whether it is proximal, middle, or distal and its associated finger or toe. The proximal phalanges are those that are closest to the hand or foot. In the hand, the prominent, knobby ends of the phalanges are known as knuckles.
