S92.033B Displaced avulsion fracture of tuberosity of unspecified calcaneus, initial encounter for open fracture

Name of the Condition

• Displaced avulsion fracture of tuberosity of unspecified calcaneus, initial encounter for open fracture

Summary

This condition involves a fracture where a bone fragment is pulled away from the tuberosity of the calcaneus (heel bone) due to tendon or ligament avulsion. The fracture is displaced, meaning the fragment has moved from its original position, and the injury is classified as open (exposing the fracture site to the external environment). It typically results from trauma and can affect weight-bearing ability and mobility, with the open nature of the fracture increasing infection risk.

Causes

High-impact trauma, such as falls or direct force to the heel, leading to avulsion where a tendon or ligament pulls a piece of bone away from its attachment site. The open fracture indicates the skin or mucous membrane has been breached, often due to the severity of the trauma.

Risk Factors

• Engaging in high-impact activities or sports.
• Osteoporosis or other bone-weakening conditions.
• Improper footwear or uneven surfaces that increase fall risk.
• Previous injuries to the heel or surrounding structures.

Symptoms

• Sudden, severe pain in the heel or back of the foot.
• Swelling, bruising, or tenderness around the heel.
• Difficulty or inability to bear weight on the affected foot.
• Visible deformity if the fracture fragment is displaced.
• Open wound or exposed bone at the fracture site.

Diagnosis

Physical examination to assess pain, swelling, and range of motion, with careful evaluation of the open wound. Imaging tests, such as X-rays or CT scans, to confirm the fracture, evaluate displacement, and assess the open nature of the injury. Additional tests may be done to rule out infection.

Treatment Options

• Immediate wound care to clean and dress the open fracture site.
• Antibiotics to prevent or treat infection.
• Immobilization with a cast or splint to allow healing.
• Pain management with medications or ice therapy.
• Surgical intervention may be required to realign and stabilize the displaced fragment.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, displacement, and infection risk. Follow-up care includes monitoring for healing, infection, and functional recovery. Physical therapy may be needed to restore mobility and strength. Regular imaging may be used to assess progress.

Complications

• Infection at the open fracture site.
• Delayed healing or nonunion.
• Chronic pain or instability.
• Nerve or vascular damage.
• Long-term mobility issues.

Lifestyle & Prevention

• Wear appropriate footwear for activities.
• Use protective gear during high-impact sports.
• Maintain bone health through diet and exercise.
• Avoid uneven surfaces or hazardous environments to reduce fall risk.

When to Seek Professional Help

Seek immediate medical attention for severe pain, visible deformity, or an open wound at the heel. Prompt care is critical to reduce infection risk and improve outcomes.

Tips for Medical Coders

Document the displaced nature of the fracture, the open status of the injury, and the initial encounter. Ensure the unspecified calcaneus is noted, and specify the open fracture type (e.g., Gustilo-Anderson classification if applicable) to support accurate coding.
