What condition can result in a malunion causing a "Dinner Fork Deformity"?

The condition that can lead to a malunion resulting in a "Dinner Fork Deformity" is indeed a Colles Fracture. A Colles Fracture typically occurs in the distal radius, often from a fall onto an outstretched hand, common in older adults. When this fracture malunites, the distal segment of the radius often tilts dorsalward, creating a characteristic deformity that resembles a dinner fork, hence the name.

This deformity specifically describes the hyperextension of the wrist and bulging at the wrist joint, which results from the upward angulation of the distal fragment of the radius. Therefore, the malunion of the fracture leads to both functional impairment and the recognizable physical appearance associated with the "Dinner Fork Deformity," making it a classic presentation in clinical settings. Understanding this allows healthcare professionals to diagnose and manage potential complications effectively.
