S93.123 Dislocation of metatarsophalangeal joint of unspecified great toe

Name of the Condition

• Dislocation of metatarsophalangeal joint of unspecified great toe

Summary

The dislocation of the metatarsophalangeal joint of the unspecified great toe involves the displacement of the joint where the big toe meets the foot, resulting in pain, swelling, and impaired movement. This condition typically arises from trauma or mechanical stress and may affect the ability to bear weight on the foot.

Causes

Trauma such as direct impact, twisting, or stubbing the toe. Sudden forceful movements that exceed the joint's normal range of motion. Repetitive stress from activities like running or jumping.

Risk Factors

• Participation in high-impact sports (e.g., soccer, basketball)
• Previous toe or foot injuries
• Wearing improper footwear that lacks support or protection
• Uneven terrain or poor surface conditions

Symptoms

• Acute pain at the site of the joint
• Swelling or bruising
• Visible deformity or misalignment of the toe
• Difficulty walking or bearing weight
• Limited range of motion

Diagnosis

Physical examination to assess pain, swelling, and joint alignment. Imaging tests such as X-rays to confirm dislocation and rule out fractures. Clinical evaluation of movement and stability.

Treatment Options

• Reduction: Manual realignment of the joint by a healthcare professional.
• Immobilization: Use of splints, buddy taping, or protective footwear to stabilize the toe.
• Pain Management: Non-steroidal anti-inflammatory drugs (NSAIDs) or other analgesics to reduce pain and inflammation.
• Rehabilitation: Physical therapy to restore strength and range of motion after healing.

Prognosis and Follow-Up

Most cases resolve with proper treatment, though recovery time varies. Follow-up care may include monitoring for healing progress and assessing functional recovery. Complications like chronic instability or arthritis are possible but uncommon with appropriate management.

Complications

• Chronic joint instability
• Post-traumatic arthritis
• Nerve or vascular damage
• Recurrent dislocation

Lifestyle & Prevention

• Wear supportive, properly fitting footwear during activities.
• Avoid uneven surfaces or hazardous environments.
• Use protective gear in high-impact sports.
• Gradually increase activity intensity to reduce stress on the joint.

When to Seek Professional Help

Seek immediate medical attention if there is severe pain, visible deformity, inability to bear weight, or signs of infection (e.g., redness, warmth, fever).

Tips for Medical Coders

Document the specific toe (unspecified great toe) and confirm the absence of additional details (e.g., laterality, open/closed status) to ensure accurate coding. Verify that the diagnosis aligns with clinical findings and imaging results.
