S82.155 Nondisplaced fracture of left tibial tuberosity

Name of the Condition

• Nondisplaced fracture of left tibial tuberosity

Summary

A nondisplaced fracture of the left tibial tuberosity involves a break in the bony prominence on the anterior upper tibia where the patellar tendon attaches. The bone fragments remain aligned, which typically preserves knee function better than displaced fractures. This injury results from trauma or excessive stress on the knee, often 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, particularly in adolescents, are common triggers.

Risk Factors

• Participation in high-impact sports (e.g., basketball, soccer)
• Adolescent growth spurts with rapid bone growth
• Previous knee injuries or tendon abnormalities
• Activities involving sudden stops or jumps

Symptoms

• Localized pain and swelling over the tibial tuberosity
• Difficulty extending the knee or bearing weight
• Bruising or tenderness on palpation
• Minimal visible deformity due to nondisplacement

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 conservative treatment fails

Prognosis and Follow-Up

Most nondisplaced fractures heal well with conservative treatment. Full recovery may take several weeks to months, depending on severity. Follow-up imaging and physical therapy are often recommended to monitor healing and restore function.

Complications

• Delayed union or nonunion of the fracture
• Chronic pain or stiffness
• Recurrent injury if activity is resumed too soon
• Rarely, avulsion of the patellar tendon

Lifestyle & Prevention

• Gradual return to activity after healing
• Proper warm-up and stretching before exercise
• Use of protective gear during high-impact sports
• Strengthening exercises for the quadriceps and surrounding muscles

When to Seek Professional Help

Seek medical attention if pain worsens, swelling increases, or mobility is severely limited. Immediate care is needed if the knee cannot bear weight or if deformity is present.

Tips for Medical Coders

Document the side (left), fracture type (nondisplaced), and anatomical location (tibial tuberosity) to support accurate coding. Include details on trauma mechanism, imaging results, and treatment to clarify the clinical scenario.
