Finger Joint Subluxation: Causes, Symptoms, and Treatment
A finger joint subluxation, also called a proximal interphalangeal (PIP) joint subluxation, is a partial dislocation that occurs when the bones in the middle joint of the finger are not aligned properly. This misalignment causes instability, pain, swelling, and limited range of motion in the affected finger. The PIP joint is responsible for bending and straightening the finger, so when it is injured, hand function can be significantly affected.
Common causes include injury, repetitive strain, or underlying conditions such as arthritis. Treatment may involve immobilization, pain management, and physical therapy to restore strength and mobility. In more severe cases, surgery may be required to stabilize the joint. Prompt medical care is important to prevent long-term complications and restore normal finger function.
