Clinical Description

Definition of Subluxation

A subluxation is defined as a partial dislocation of a joint, where the surfaces of the joint are misaligned but still maintain some contact. In the case of the proximal interphalangeal (PIP) joint of the index finger, this can occur due to trauma, repetitive stress, or underlying conditions that affect joint stability.

Anatomy of the Proximal Interphalangeal Joint

The proximal interphalangeal joint is located between the first (proximal) and second (distal) phalanges of the finger. It plays a crucial role in finger movement, allowing for flexion and extension. The joint is stabilized by ligaments, tendons, and surrounding musculature, making it susceptible to injuries such as subluxations.

Causes

Subluxation of the PIP joint can result from various factors, including:
- Trauma: Direct impact or falls can lead to joint misalignment.
- Sports Injuries: Activities that involve gripping or throwing can increase the risk of subluxation.
- Repetitive Strain: Overuse of the finger in certain activities may weaken the joint's stability.
