16 Αυγ 2024 · 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.

A thumb proximal phalanx fracture produces a discontinuity in the proximal phalanx contours that can be complete or incomplete. A thumb proximal phalanx fracture is caused by a direct force that exceeds the breaking point of the bone.
Proximal phalanx fractures are the most common pediatric hand fracture 1. The fracture is generally well seen on plain radiographs, angulation of these fractures is best seen on the lateral projection 2. Ultrasonography can be used for fractures that are difficult to see or when there are doubts.
The bone under the nail that makes up the tip of the thumb is called the distal phalanx. The next bone is called the proximal phalanx. The distal phalanx and proximal phalanx connect via the interphalangeal (IP) joint, which allows you to bend the tip of your thumb.

8 Αυγ 2023 · Each thumb (first digit) contains a proximal and distal phalanx, while the index (second digit), long (third digit), ring (fourth digit), and small (fifth digit) fingers all contain a proximal, middle, and distal phalanx.
18 Ιουν 2024 · Anatomy of special importance to proximal phalanx fractures is described below; a more detailed discussion of finger anatomy is found separately. (See "Finger and thumb anatomy".) Proximal phalanx fractures often present with apex volar angulation.
