The phalanges / f ə ˈ l æ n dʒ iː z / (sg.: phalanx / ˈ f æ l æ ŋ k s /) are digital bones in the hands and feet of most vertebrates. In primates, the thumbs and big toes have two phalanges while the other digits have three phalanges. The phalanges are classed as long bones.

Phalanx Fractures are common hand injuries that involve the proximal, middle or distal phalanx. Diagnosis can be confirmed with orthogonal radiographs of the involve digit. Treatment involves immobilization or surgical fixation depending on location, severity and alignment of injury.

Aug 13, 2018 · Being the first row of finger bones, the proximal phalanges play the vital role of connecting the upper parts of the fingers with the palm, allowing us to use our fingers for almost all daily activities.

Nov 13, 2023 · Each hand has a total of five proximal phalanges, one in each digit. Compared to the middle and distal phalanges, they are the largest ones. The proximal phalanx of the thumb is an exception because it is shorter and more stout compared to the rest. Each proximal phalanx consists of three parts;

The phalanx (pl.: phalanxes or phalanges) [1] was a rectangular mass military formation, usually composed entirely of heavy infantry armed with spears, pikes, sarissas, or similar polearms tightly packed together.

Each phalanx has two centers of ossification, the first one for the body or shaft, and the second for the base or proximal extremity. The shaft starts to ossify quite early, around the eighth week of fetal growth.

Apr 10, 2024 · 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.

The first phalanx is made up of proximal and distal bones. The second through fifth phalanges are made up of proximal, middle, and distal bones. Each phalanx has a base, shaft, and head.

Jun 28, 2024 · 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.

In the thumb, which has only two phalanges, the first phalanx articulates by its proximal extremity with the metacarpal bone and by its distal with the ungual phalanx.
