Key Concepts

Distal Interphalangeal Joint Dislocation

This refers to the dislocation of the joint at the tip of the finger. Understanding its anatomy, mechanics, and typical displacement patterns is crucial in diagnosing and managing such injuries.

Volar Plate

The volar plate is a thick ligament on the palmar side of the joint that provides stability. In the context of dislocations, its entrapment can prevent the joint from being easily reduced, making it a focal point in management decisions.

Irreducible Dislocation

An irreducible dislocation is one that cannot be realigned with closed (non-surgical) techniques. This is often due to soft tissue structures, such as the entrapped volar plate, obstructing proper repositioning of the joint.
