S93.113 Dislocation of interphalangeal joint of unspecified great toe

Name of the Condition

• Dislocation of interphalangeal joint of unspecified great toe

Summary

Dislocation of the interphalangeal joint of the 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, often performed under local anesthesia.
• Immobilization: Use of a splint or bandage to stabilize the toe during healing.
• Pain management: Medications to reduce pain and inflammation.
• Rehabilitation: Physical therapy to restore strength and mobility after healing.

Prognosis and Follow-Up

Most dislocations heal well with proper treatment, but recovery time depends on severity. Follow-up care ensures proper healing and may include monitoring for complications. Return to normal activity is typically gradual, guided by clinical progress.

Complications

• Chronic pain or stiffness
• Recurrent dislocation due to joint instability
• Arthritis in the affected joint over time
• Nerve or blood vessel damage (rare)

Lifestyle & Prevention

• Wear supportive, well-fitted footwear during activities.
• Use protective gear in high-risk sports.
• Avoid uneven surfaces that increase fall risk.
• Strengthen foot and toe muscles to improve stability.

When to Seek Professional Help

Seek immediate care if the toe is severely deformed, unable to bear weight, or accompanied by intense pain. Also, consult a healthcare provider if symptoms worsen or do not improve with initial treatment.

Tips for Medical Coders

Document the affected toe (unspecified in this case) and the nature of the injury (dislocation). Ensure clinical notes support the diagnosis and specify if the injury is acute or related to trauma. Code S93.113 is used when the interphalangeal joint of the great toe is dislocated, with no side specified.
