Abstract:
Flexor tendon entrapment in fractures of the proximal phalanx is a rare occurrence. This complication has only been reported in association with displaced epiphyseal and diaphyseal fractures. Here we describe a case of an unusual proximal phalangeal fracture pattern with functional hindrance of the flexor mechanism. A 34-year-old man presented with an absent flexor digitorum superficialis (FDS) and flexor digitorum profundus (FDP) function of the ring finger 4 weeks after an injury. X-Ray Examination revealed a bony fragment on the radial volar aspect of the proximal phalanx. USS revealed an intact FDS and FDP tendons. Excision of the bony fragment with tenolysis led to restoration of function.

01:27Fractures: 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...

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...
