S82.154 Nondisplaced fracture of right tibial tuberosity

Name of the Condition

• Nondisplaced fracture of right tibial tuberosity

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. The bone fragments remain in their normal alignment, preserving the structural integrity of the area. This injury typically results from trauma or excessive stress on the knee, particularly in active individuals.

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 strength and mobility
• Surgical intervention if displacement occurs or if conservative measures fail

Prognosis and Follow-Up

Most nondisplaced fractures heal well with conservative treatment, allowing a return to normal activities within several weeks. Follow-up imaging may be recommended to monitor healing progress. Physical therapy is often advised to prevent stiffness and regain full function.

Complications

• Delayed union or nonunion of the fracture
• Chronic pain or instability in the knee
• Post-traumatic arthritis
• Nerve or vascular damage (rare)

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. Include details on the mechanism of injury, clinical findings, and imaging results to support the diagnosis. Ensure the code aligns with the clinical documentation and reflects the absence of displacement.
