S89.122 Salter-Harris Type II physeal fracture of lower end of left tibia

Name of the Condition

• Salter-Harris Type II physeal fracture of lower end of left tibia

Summary

A Salter-Harris Type II physeal fracture of the lower end of the left tibia is an injury involving a fracture through the growth plate (physis) at the distal tibia, with the fracture line extending into the metaphysis. This type of fracture is common in children and adolescents due to the presence of open growth plates. The injury disrupts the growth plate, a critical area for bone development, and may result from trauma to the ankle or lower leg.

Causes

Common causes include trauma from falls, sports injuries, or accidents where force is applied to the ankle or lower leg. Direct impact, twisting motions, or rotational stress can disrupt the growth plate, leading to a fracture that extends into the metaphysis. High-impact events or sudden stress to the tibia may also precipitate this type of injury.

Risk Factors

• Age: More common in children and adolescents due to open growth plates.
• Activity Level: Participation in contact sports or activities with a risk of leg trauma.
• Anatomical Factors: Variations in bone structure or growth plate vulnerability.

Symptoms

• Pain and tenderness around the ankle or distal tibia.
• Swelling and possible bruising near the affected area.
• Difficulty or reluctance to bear weight on the affected leg.
• Visible deformity in severe cases.

Diagnosis

Physical examination to assess pain, swelling, and range of motion, followed by imaging such as X-rays to visualize the fracture pattern. The fracture line through the physis and extension into the metaphysis confirms the Salter-Harris Type II classification. Additional imaging may be used if the diagnosis is unclear or to assess for associated injuries.

Treatment Options

Treatment depends on the severity and displacement of the fracture. Nondisplaced fractures may be managed with immobilization using a cast or splint. Displaced fractures often require closed reduction or surgical intervention to realign the bone. Follow-up imaging ensures proper healing and alignment.

Prognosis and Follow-Up

Prognosis is generally favorable with appropriate treatment, though growth plate injuries carry a risk of long-term complications like limb length discrepancy or angular deformity. Regular follow-up with imaging and clinical assessments monitors healing and growth plate function. Physical therapy may be recommended to restore strength and mobility.

Complications

Potential complications include growth arrest, limb length discrepancy, angular deformity, or chronic pain. Infection or nonunion may occur with surgical intervention. Early recognition and management reduce the risk of adverse outcomes.

Lifestyle & Prevention

Preventive measures include using proper protective equipment during sports, ensuring safe play environments, and avoiding high-risk activities without supervision. Strengthening exercises and balance training may reduce injury risk. Prompt treatment of minor injuries prevents progression to more severe fractures.

When to Seek Professional Help

Seek immediate medical attention for severe pain, inability to bear weight, visible deformity, or signs of infection (e.g., fever, redness, drainage). Delayed treatment may worsen outcomes or lead to complications.

Tips for Medical Coders

Document the laterality (left tibia) and confirm the fracture type (Salter-Harris Type II) with clinical and imaging findings. Ensure the code aligns with the specific anatomical location and fracture characteristics. Verify that the encounter type and fracture status (e.g., open/closed) are accurately captured if applicable.
