Abstract:
A case of unusual displacement in a finger, with an avulsion fragment from the dorsal metacarpal head of the finger displaced in the palmar direction under the volar plate is described. An 18-year-old woman presented with complaint of difficulty flexing the metacarpophalangeal (MP) joint of the right little finger after a fall onto the outstretched hand. Three-dimensional computed tomography (CT) was useful for diagnosing this condition. Use of both palmar and dorsal approaches was needed to reduce the displacement and to fix the bones with a single screw. Bone union was achieved, and the patient has been asymptomatic for more than 10 months.

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...

Anterior Compartment
The anterior compartment muscles originate from the humerus. They primarily function as flexors and are also known as flexor muscles. They typically insert on the carpals, metacarpals, and phalanges. The superficial layer includes the flexor carpi radialis,...
