S92.036 Nondisplaced avulsion fracture of tuberosity of unspecified calcaneus

Name of the Condition

• Nondisplaced avulsion fracture of tuberosity of unspecified calcaneus

Summary

This condition involves a fracture where a small piece of bone is pulled away from the tuberosity of the calcaneus (heel bone) due to tendon or ligament tension. The fracture is nondisplaced, meaning the avulsed fragment remains in its original position. It typically results from trauma and can affect mobility and weight-bearing ability, with severity depending on the size of the fragment.

Causes

High-impact trauma, such as falls or direct force to the heel. Sudden, forceful muscle contractions (e.g., during sports or physical activity) that pull on the attached tendon or ligament.

Risk Factors

• Engaging in high-impact activities or sports.
• Osteoporosis or other bone-weakening conditions.
• Improper footwear or uneven surfaces that increase fall risk.

Symptoms

• Sudden, localized pain at the heel or back of the foot.
• Swelling, bruising, or tenderness around the affected area.
• Difficulty or inability to bear weight on the foot.
• Possible visible lump or deformity if the 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 the size and displacement of the avulsed fragment.

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 large or unstable (rare for nondisplaced cases).

Prognosis and Follow-Up

Most nondisplaced avulsion fractures heal well with conservative treatment. Follow-up imaging may be used to monitor healing. Return to normal activities depends on the size of the fragment and adherence to treatment plans.

Complications

• Delayed healing or nonunion if the fragment is large.
• Chronic pain or instability if the tendon/ligament attachment is compromised.
• Post-traumatic arthritis in severe cases.

Lifestyle & Prevention

• Wear supportive footwear during high-impact activities.
• Strengthen lower leg muscles to reduce strain on the heel.
• Avoid uneven surfaces or high-risk activities if prone to falls.

When to Seek Professional Help

Seek immediate care for severe pain, inability to bear weight, or visible deformity. Follow up with a healthcare provider if symptoms worsen or do not improve with initial treatment.

Tips for Medical Coders

Document the location (unspecified calcaneus) and nondisplaced status clearly. Include details on trauma mechanism, imaging findings, and treatment to support code specificity. Ensure documentation aligns with the avulsion fracture definition for accurate coding.
