S63.412S Traumatic rupture of collateral ligament of right middle finger at metacarpophalangeal and interphalangeal joint, sequela

Name of the Condition

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

Summary

This condition represents the residual effects of a previously ruptured collateral ligament in the right middle finger, affecting the metacarpophalangeal and interphalangeal joints. It follows an initial traumatic injury and may involve ongoing functional impairment or structural changes.

Causes

The sequela arises from a prior traumatic rupture of the collateral ligament, typically caused by direct injury or forceful bending/twisting of the finger. The current state reflects the long-term consequences of that initial event.

Risk Factors

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

Symptoms

• Persistent pain, reduced range of motion, instability, or deformity in the right middle finger, potentially with chronic swelling or stiffness.

Diagnosis

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

Treatment Options

• Rehabilitation: Targeted therapy to improve strength and mobility.
• Supportive Devices: Splints or braces for stability.
• Surgical Intervention: Considered for severe instability or functional impairment.

Prognosis and Follow-Up

Outcomes depend on the severity of the initial injury and treatment. Regular follow-up monitors functional recovery and addresses complications. Mild cases may stabilize with therapy, while severe cases may have lasting limitations.

Complications

• Chronic pain, joint stiffness, reduced grip strength, or recurrent instability.

Lifestyle & Prevention

• Avoid activities that stress the finger; use protective gear during sports. Strengthening exercises and proper ergonomics may support recovery.

When to Seek Professional Help

Seek care for worsening pain, new swelling, or loss of function, as these may indicate complications or require adjusted treatment.

Tips for Medical Coders

Document the sequela status and specify the right middle finger involvement. Include details of the prior traumatic event and current functional impact to support code assignment. Ensure clinical correlation with the residual effects of the ligament rupture.
