S82.153 Displaced fracture of unspecified tibial tuberosity

Name of the Condition

• Displaced fracture of unspecified tibial tuberosity

Summary

A displaced fracture of the tibial tuberosity involves a break in the bony prominence on the anterior tibia where the patellar tendon attaches. Displacement means the bone fragments are misaligned, which can affect knee function. 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

• Severe pain and swelling over the tibial tuberosity
• Inability to fully extend the knee or bear weight
• Visible deformity or abnormal positioning of the knee
• Bruising or discoloration in the affected area

Diagnosis

Diagnosis involves a physical examination to assess pain, swelling, and deformity. Imaging studies, such as X-rays, are used to confirm the fracture and evaluate displacement. Additional tests like MRI may be ordered to assess soft tissue damage.

Treatment Options

• Immobilization with a brace or cast to stabilize the fracture
• Pain management with analgesics or anti-inflammatory medications
• Surgical intervention for severe displacement or unstable fractures
• Physical therapy to restore knee function and strength

Prognosis and Follow-Up

Most displaced fractures of the tibial tuberosity heal with appropriate treatment, but recovery time varies. Follow-up care includes monitoring for proper healing and gradual return to activity. Complications like malunion or persistent pain may require further intervention.

Complications

• Malunion or nonunion of the fracture
• Chronic pain or instability in the knee
• Damage to surrounding soft tissues or nerves
• Early-onset arthritis in the affected joint

Lifestyle & Prevention

• Use proper protective gear during sports or high-risk activities
• Strengthen quadriceps and knee muscles to reduce injury risk
• 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 knee pain, inability to bear weight, visible deformity, or signs of an open fracture (e.g., bone protruding through the skin).

Tips for Medical Coders

This code (S82.153) is for a displaced fracture of the unspecified tibial tuberosity. Documentation should specify the fracture type (displaced) and location (tibial tuberosity) without indicating laterality. Ensure clinical notes support the displacement and absence of additional details like open fracture or encounter type.
