S63.411S Traumatic rupture of collateral ligament of left index finger at metacarpophalangeal and interphalangeal joint, sequela

Name of the Condition

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

Summary

This condition represents a residual effect (sequela) of a traumatic rupture of the collateral ligament in the left index finger, affecting the metacarpophalangeal and interphalangeal joints. It follows an initial injury and may involve persistent symptoms or structural changes.

Causes

The primary cause is a prior traumatic event that resulted in a rupture of the collateral ligament in the left index finger. This typically stems from forceful bending, twisting, or direct impact to the finger.

Risk Factors

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

Symptoms

• Persistent pain, swelling, or instability in the left index finger, reduced range of motion, and difficulty with fine motor tasks.

Diagnosis

A physical examination, often with imaging (e.g., X-rays or MRI), is used to evaluate residual ligament damage or joint instability. Clinical history of the initial injury is also considered.

Treatment Options

• Conservative Management: Splinting or bracing to stabilize the finger, physical therapy to improve strength and mobility.
• Surgical Intervention: May be considered for severe instability or functional impairment.

Prognosis and Follow-Up

Recovery depends on the severity of the initial injury and treatment. Chronic pain or stiffness may persist, requiring ongoing monitoring and rehabilitation.

Complications

• Chronic joint instability, persistent pain, reduced dexterity, or secondary arthritis in the affected joints.

Lifestyle & Prevention

• Avoid activities that stress the left index finger, use protective gear during sports, and practice proper ergonomic techniques to minimize strain.

When to Seek Professional Help

Seek care if symptoms worsen, interfere with daily activities, or if new swelling, pain, or instability develops.

Tips for Medical Coders

Document the sequela nature of the condition, including the history of the initial traumatic rupture and any residual functional impairment. Ensure clinical notes support the chronicity and impact on the left index finger.
