S82.154B Nondisplaced fracture of right tibial tuberosity, initial encounter for open fracture type I or II

Name of the Condition

• Nondisplaced fracture of right tibial tuberosity, initial encounter for open fracture type I or II

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 misalignment of bone fragments. This injury is classified as an open fracture type I or II, meaning the skin over the fracture site is compromised but the wound is limited. The tibial tuberosity is critical for knee extension, and even nondisplaced fractures can impact function.

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. Open fractures occur when the injury breaches the skin, exposing the fracture site.

Risk Factors

• Participation in high-impact sports (e.g., basketball, soccer)
• Adolescent growth spurts, especially in athletes
• Previous knee injuries or surgeries
• Activities involving sudden stops or jumps

Symptoms

• Localized pain and swelling over the tibial tuberosity
• Difficulty extending the knee or bearing weight
• Visible wound or laceration at the fracture site (for open fractures)
• 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. For open fractures, the wound is assessed for contamination or infection risk. Additional tests like MRI may be ordered to assess soft tissue damage.

Treatment Options

• Wound care and irrigation to clean the open fracture site
• Immobilization with a brace or cast to stabilize the fracture
• Pain management with analgesics or anti-inflammatory medications
• Surgical intervention if the fracture is unstable or the wound requires debridement

Prognosis and Follow-Up

Prognosis is generally favorable with proper treatment, as nondisplaced fractures often heal without significant complications. Follow-up care includes monitoring for infection, especially in open fractures, and gradual return to activity as healing progresses. Physical therapy may be recommended to restore knee function.

Complications

• Infection at the open fracture site
• Delayed healing or nonunion
• Persistent pain or functional limitations
• Post-traumatic arthritis in the knee

Lifestyle & Prevention

• Use protective gear during high-impact sports
• Strengthen quadriceps and surrounding muscles to reduce stress on the tibial tuberosity
• Avoid sudden, forceful movements that strain the knee
• Maintain bone health through proper nutrition and exercise

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, inability to bear weight, visible deformity, or an open wound at the knee. Prompt evaluation is critical for open fractures to prevent infection and ensure proper treatment.

Tips for Medical Coders

Document the fracture as nondisplaced and specify the right tibial tuberosity. For open fractures, note the type (I or II) and ensure the initial encounter is clearly documented. Include details about wound characteristics and any associated injuries to support coding accuracy.
