S82.154A Nondisplaced fracture of right tibial tuberosity, initial encounter for closed fracture

Name of the Condition

• Nondisplaced fracture of right tibial tuberosity, initial encounter for closed fracture

Summary

A nondisplaced fracture of the right tibial tuberosity involves a break in the bony prominence on the anterior upper tibia where the patellar tendon attaches, with no significant misalignment of the bone fragments. This injury typically results from trauma or excessive stress on the knee, particularly in active individuals. The fracture is closed, meaning the skin remains intact, and this is the initial encounter for treatment.

Causes

Traumatic injury is the primary cause, such as direct impact to the knee, falls, or sudden forceful contraction of the quadriceps muscle. Sports-related incidents, motor vehicle accidents, or other high-impact events can lead to this fracture.

Risk Factors

• Participation in activities with rapid knee extension or jumping (e.g., basketball, soccer)
• Adolescent growth spurts, especially in athletes
• Previous knee injuries or surgeries
• Osteoporosis or bone-weakening conditions

Symptoms

• Localized pain and swelling over the tibial tuberosity
• Difficulty extending the knee or bearing weight
• Visible deformity or prominence at the fracture site
• Bruising or tenderness on palpation

Diagnosis

Diagnosis involves a physical examination to assess pain, swelling, and functional limitations. Imaging studies, such as X-rays, are used to confirm the fracture and evaluate displacement. CT or MRI may be ordered for complex cases.

Treatment Options

• Immobilization with a brace or cast to stabilize the fracture
• Pain management with analgesics or anti-inflammatory medications
• Physical therapy to restore knee function and strength
• Surgical intervention if displacement occurs or conservative treatment fails

Prognosis and Follow-Up

Most nondisplaced fractures heal well with conservative treatment, allowing return to normal activities within 6–12 weeks. Follow-up appointments monitor healing progress and functional recovery. Physical therapy may be recommended to prevent stiffness and regain strength.

Complications

• Delayed union or nonunion of the fracture
• Chronic pain or instability in the knee
• Post-traumatic arthritis
• Re-fracture due to inadequate healing

Lifestyle & Prevention

• Use proper protective gear during sports or high-impact activities
• Strengthen quadriceps and surrounding muscles to support the knee
• Avoid sudden, forceful movements that strain the knee
• Maintain bone health through adequate nutrition and exercise

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, inability to bear weight, visible deformity, or signs of infection (e.g., fever, redness, drainage) at the fracture site.

Tips for Medical Coders

Document the fracture as nondisplaced and specify the right tibial tuberosity. Note the initial encounter for a closed fracture. Include details on imaging results, treatment provided, and any follow-up care to support accurate coding. Ensure documentation aligns with the clinical findings and treatment plan.
