S63.410S Traumatic rupture of collateral ligament of right index finger at metacarpophalangeal and interphalangeal joint, sequela

Name of the Condition

• Traumatic rupture of collateral ligament of right index finger at metacarpophalangeal and interphalangeal joint, sequela

Summary

This condition represents a late effect (sequela) of a traumatic rupture of the collateral ligament in the right index finger, affecting the metacarpophalangeal and interphalangeal joints. It occurs following the initial injury and may involve residual impairment or complications from the original trauma.

Causes

The primary cause is a prior traumatic event that resulted in a rupture of the collateral ligament in the right index finger. This could include injuries from sports, falls, or accidents where the finger was forcefully bent or twisted.

Risk Factors

• History of hand or finger injuries, participation in contact sports, occupations involving repetitive finger strain, and activities with a high risk of finger trauma.

Symptoms

• Persistent pain, swelling, or instability in the right index finger, reduced range of motion, and potential deformity or weakness at the affected joints.

Diagnosis

A physical examination and review of prior injury history are used to assess residual ligament damage. Imaging tests like X-rays or MRI may be performed to evaluate joint stability and soft tissue healing.

Treatment Options

• Rehabilitation: Physical therapy to improve strength and flexibility.
• Supportive Devices: Splints or braces to stabilize the finger.
• Surgical Intervention: In cases of persistent instability, reconstructive surgery may be considered.

Prognosis and Follow-Up

Recovery depends on the severity of the initial injury and treatment. Mild cases may improve with therapy, while severe cases may require ongoing management to address functional limitations.

Complications

• Chronic pain, joint instability, reduced grip strength, or arthritis in the affected joints.

Lifestyle & Prevention

• Avoid activities that strain the right index finger. Use protective gear during sports or high-risk tasks. Strengthen hand muscles through targeted exercises.

When to Seek Professional Help

Seek care if pain worsens, swelling persists, or there is difficulty moving the finger, as these may indicate unresolved ligament damage or complications.

Tips for Medical Coders

Document the sequela status and specify the right index finger involvement. Include details of the original injury and any residual impairments to support the sequela code. Ensure clinical notes reflect the chronic nature of the condition.
