S92.032S Displaced avulsion fracture of tuberosity of left calcaneus, sequela

Name of the Condition

• Displaced avulsion fracture of tuberosity of left calcaneus, sequela

Summary

This condition represents a displaced avulsion fracture of the tuberosity of the left calcaneus (heel bone) during the sequela phase. The fracture occurs when a tendon or ligament pulls a bone fragment away from its attachment site, and the fragment remains displaced. The term "sequela" indicates this is a residual effect or complication following the initial injury, with ongoing symptoms or structural changes. It may affect weight-bearing ability and mobility due to persistent bone or soft tissue damage.

Causes

The sequela results from the initial avulsion fracture, where trauma (e.g., falls, direct force to the heel) caused a tendon or ligament to pull a bone fragment away. The displaced fragment and associated tissue damage persist, leading to long-term effects. The sequela phase reflects incomplete healing or chronic changes from the original injury.

Risk Factors

• Prior avulsion fracture of the left calcaneus tuberosity.
• Inadequate initial treatment or healing.
• Underlying bone conditions (e.g., osteoporosis) that impair recovery.
• High-impact activities or repetitive stress on the heel.

Symptoms

• Chronic pain or discomfort in the heel or back of the foot.
• Persistent swelling, bruising, or tenderness.
• Reduced range of motion or stiffness in the ankle/foot.
• Difficulty bearing weight or altered gait.
• Visible deformity if the fragment remains displaced.

Diagnosis

Evaluation includes a physical exam to assess pain, swelling, and mobility. Imaging (e.g., X-rays, CT scans) confirms the displaced fragment and assesses healing. Clinical history of the initial injury and current symptoms helps determine the sequela phase. Additional tests (e.g., MRI) may evaluate soft tissue damage.

Treatment Options

• Pain management (medications, physical therapy).
• Orthotics or bracing to support the heel.
• Activity modification to reduce stress.
• Surgical intervention (e.g., fragment removal or fixation) if severe displacement or functional impairment persists.
• Rehabilitation to restore strength and mobility.

Prognosis and Follow-Up

Prognosis depends on the extent of initial injury, treatment, and healing. Most patients improve with conservative care, but residual symptoms (e.g., pain, stiffness) may persist. Regular follow-up monitors healing, functional recovery, and addresses complications. Long-term mobility and quality of life vary based on individual factors.

Complications

• Chronic pain or arthritis in the heel.
• Persistent deformity or instability.
• Reduced mobility or gait abnormalities.
• Nerve damage or soft tissue scarring.
• Increased risk of re-injury.

Lifestyle & Prevention

• Wear supportive footwear to reduce heel stress.
• Avoid high-impact activities that strain the heel.
• Maintain bone health (e.g., calcium, vitamin D) to support healing.
• Engage in gradual, guided rehabilitation post-injury.
• Use protective gear during sports or high-risk activities.

When to Seek Professional Help

Seek care if symptoms worsen (e.g., increased pain, swelling), new deformity appears, or mobility declines. Prompt evaluation is needed for severe pain, inability to bear weight, or signs of infection (e.g., redness, fever). Follow-up is critical for monitoring sequela progression.

Tips for Medical Coders

Document the sequela phase clearly, noting the history of the initial avulsion fracture and current residual effects. Include details on displacement, functional impact, and any ongoing treatment. Ensure the code S92.032S is used only when the condition is a sequela of the specified fracture, with no active acute injury.
