S92.033 Displaced avulsion fracture of tuberosity of unspecified calcaneus

Name of the Condition

• Displaced avulsion fracture of tuberosity of unspecified calcaneus

Summary

This condition involves a fracture where a fragment of bone is pulled away from the tuberosity of the calcaneus (heel bone) due to tendon or ligament avulsion. The fracture is displaced, meaning the bone fragment has moved from its original position. It typically results from trauma and can affect weight-bearing ability and mobility.

Causes

High-impact trauma, such as falls or direct force to the heel. Avulsion occurs when a tendon or ligament pulls a piece of bone away from its attachment site, often seen in sports injuries or sudden, forceful movements.

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.

Diagnosis

Physical examination to assess pain, swelling, and range of motion. Imaging tests, such as X-rays or CT scans, to confirm the fracture and evaluate its displacement and attachment to the tuberosity.

Treatment Options

• Rest and immobilization with a cast or splint to allow healing.
• Pain management with medications or ice therapy.
• Surgical intervention if the fragment is significantly displaced or unstable.

Prognosis and Follow-Up

Recovery depends on the severity of displacement and treatment. Most cases heal with immobilization, but follow-up imaging may be needed to assess healing. Physical therapy is often recommended to restore strength and mobility.

Complications

• Delayed healing or nonunion of the fracture.
• Chronic pain or instability in the heel.
• Nerve or tendon damage from the injury or surgery.

Lifestyle & Prevention

• Wear supportive footwear during high-impact activities.
• Maintain bone health through proper nutrition and exercise.
• Avoid uneven surfaces or activities with high fall risk.

When to Seek Professional Help

Seek immediate care if you experience sudden, severe heel pain after trauma, especially if you cannot bear weight or notice deformity.

Tips for Medical Coders

Document the side (unspecified in this case) and displacement status clearly. Ensure clinical notes specify the fracture type and any associated injuries to support accurate coding.
