S63.418 Traumatic rupture of collateral ligament of other finger at metacarpophalangeal and interphalangeal joint

Name of the Condition

• Traumatic rupture of collateral ligament of other finger at metacarpophalangeal and interphalangeal joint

Summary

This condition involves a tear or rupture of the collateral ligament in a finger other than the index, middle, ring, or little finger, affecting the joints where the finger connects to the hand (metacarpophalangeal) and the joints within the finger (interphalangeal). It typically results from an injury or trauma.

Causes

The primary cause is direct injury or trauma to the finger, such as from sports injuries, falls, or accidents where the finger is forcefully bent or twisted.

Risk Factors

• Participating in contact sports, having a history of hand injuries, engaging in activities with repetitive finger motion or strain, and occupations that stress the fingers.

Symptoms

• Pain and swelling in the finger, decreased range of motion, bruising, and difficulty bending or straightening the finger.

Diagnosis

A physical examination, often with imaging tests like X-rays or MRI, is used to assess ligament damage.

Treatment Options

• Rest and Immobilization: Using splints to stabilize the finger.
• Physical Therapy: Exercises to restore strength and flexibility.
• Surgery: In severe cases, surgical repair may be necessary.

Prognosis and Follow-Up

Recovery depends on the severity of the rupture and treatment. Mild cases may heal with rest and therapy, while severe cases may require longer rehabilitation or surgical intervention.

Complications

• Chronic pain, instability of the joint, reduced range of motion, or arthritis in the affected joint.

Lifestyle & Prevention

• Use protective gear during sports or activities with high finger injury risk. Avoid repetitive strain or forceful finger movements.

When to Seek Professional Help

Seek medical attention if pain is severe, swelling persists, or the finger cannot move properly after an injury.

Tips for Medical Coders

Document the specific finger affected (other than index, middle, ring, or little) and confirm the involvement of both metacarpophalangeal and interphalangeal joints. Ensure trauma is clearly linked to the ligament rupture.
