Subluxation of Proximal Interphalangeal Joint of Unspecified Finger, Initial Encounter

Name of the Condition

• Commonly known as Finger Joint Subluxation.
• Technically referred to as Subluxation of Proximal Interphalangeal (PIP) Joint.

Summary

• This condition involves a partial dislocation of the proximal interphalangeal joint of an unspecified finger, meaning the joint is not fully in its normal position. It is often caused by trauma and usually results in pain and swelling at the joint.

Causes

• Typically results from acute trauma, such as a direct blow or hyperextension.
• Repetitive stress to the joint can also result in subluxation.

Risk Factors

• Engaging in sports or activities that involve hand use (e.g., basketball, rock climbing).
• Previous hand injuries or ligament laxity.

Symptoms

• Pain and tenderness around the affected joint.
• Swelling and possible bruising.
• Restricted range of motion and instability of the joint.

Diagnosis

• Physical examination by a healthcare provider, noting joint instability or deformity.
• X-rays may be used to confirm the subluxation and check for associated fractures.

Treatment Options

• Rest and Immobilization: Splinting or buddy taping to immobilize and allow healing.
• Pain Management: Anti-inflammatory medications to reduce pain and swelling.
• Physical Therapy: To restore movement and strengthen the joint post-healing.

Prognosis and Follow-Up

• Generally favorable with proper treatment, though recovery may take weeks.
• Regular follow-up to monitor healing progress and to prevent future subluxations.

Complications

• Recurrent subluxations.
• Possible development of arthritis in the affected joint.

Lifestyle & Prevention

• Wearing protective gear during high-risk activities.
• Strengthening hand and finger muscles through exercises.
• Avoiding movements that may overly stress the fingers.

When to Seek Professional Help

• If the finger appears deformed or function is impaired.
• Persistent pain, swelling, or inability to move the joint normally.
