S63.421S Traumatic rupture of palmar ligament of left index finger at metacarpophalangeal and interphalangeal joint, sequela

Name of the Condition

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

Summary

This condition represents the residual effects of a previously ruptured palmar ligament in the left index finger, affecting the metacarpophalangeal and interphalangeal joints. It occurs after the acute injury phase and may involve persistent structural or functional changes.

Causes

The sequela results from a prior traumatic event that caused the initial ligament rupture, such as a forceful bend, twist, or impact to the left index finger.

Risk Factors

• History of hand trauma, participation in activities with high finger strain, occupations requiring repetitive hand use, and delayed or inadequate treatment of the initial injury.

Symptoms

• Chronic pain, reduced finger mobility, swelling, instability, or deformity in the left index finger, particularly during movement or weight-bearing.

Diagnosis

Evaluation includes a physical exam to assess joint stability and range of motion, with imaging (e.g., X-rays, MRI) to identify residual ligament damage or joint changes. Clinical history of the prior injury is critical.

Treatment Options

• Conservative Management: Splinting, activity modification, and physical therapy to improve function.
• Surgical Intervention: Reconstructive procedures for severe instability or functional impairment.
• Pain Management: Medications or injections to address chronic discomfort.

Prognosis and Follow-Up

Outcomes depend on the extent of residual damage and treatment. Regular follow-up monitors joint stability, pain, and functional recovery. Long-term management may be needed for persistent symptoms.

Complications

• Chronic pain, joint stiffness, reduced grip strength, or recurrent instability. Arthritis may develop in affected joints over time.

Lifestyle & Prevention

• Avoid repetitive or high-stress finger activities. Use protective gear during sports or work. Strengthening exercises and proper ergonomics may support recovery.

When to Seek Professional Help

Seek care if symptoms worsen, new pain or swelling occurs, or functional limitations impact daily tasks. Prompt evaluation is important for progressive or unmanaged symptoms.

Tips for Medical Coders

Document the sequela status and specify the left index finger, metacarpophalangeal, and interphalangeal joint involvement. Include details of the prior injury and current clinical findings to support the sequela diagnosis.
