S93.112 Dislocation of interphalangeal joint of left great toe

Name of the Condition

• Dislocation of interphalangeal joint of left great toe

Summary

Dislocation of the interphalangeal joint of the left great toe involves the complete displacement of the joint between the bones of the big toe, resulting in misalignment. This injury typically causes pain, swelling, and impaired movement, often due to trauma or forceful bending. The interphalangeal joint is the joint closest to the tip of the toe, and dislocation here means the bones are no longer in their normal position.

Causes

Trauma such as direct impact, twisting, or stubbing the toe. Sudden forceful movements that exceed the joint's normal range of motion. Accidents, sports injuries, or falls that apply significant stress to the toe.

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

• Pain at the affected 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 provider.
• Immobilization: Use of splints or bandages to stabilize the toe during healing.
• Pain management: Medications to reduce pain and inflammation.
• Rehabilitation: Exercises to restore strength and range of motion once healing allows.

Prognosis and Follow-Up

Most dislocations of the interphalangeal joint of the great toe heal well with proper treatment, though some may experience residual stiffness or discomfort. Follow-up care ensures proper healing and addresses any complications. Recovery time varies but typically ranges from a few weeks to several months, depending on severity and adherence to treatment.

Complications

• Chronic pain or stiffness
• Recurrent dislocation due to joint instability
• Arthritis in the affected joint over time
• Nerve or tissue damage from the injury

Lifestyle & Prevention

• Wear supportive, well-fitting footwear during activities.
• Use protective gear (e.g., toe guards) in high-risk sports.
• Avoid uneven surfaces or hazardous environments that increase fall risk.
• Strengthen foot and toe muscles through targeted exercises.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, visible deformity, inability to bear weight, or signs of infection (e.g., redness, pus). Prompt care reduces the risk of complications and improves outcomes.

Tips for Medical Coders

Use code S93.112 for dislocation of the interphalangeal joint of the left great toe. Document the laterality (left) and specify the joint affected (interphalangeal) to ensure accurate coding. Include details about the injury mechanism, treatment provided, and any associated complications to support clinical coding and billing.
