S89.029 Salter-Harris Type II physeal fracture of upper end of unspecified tibia

Name of the Condition

• Salter-Harris Type II physeal fracture of upper end of unspecified tibia

Summary

A Salter-Harris Type II physeal fracture of the upper end of the unspecified tibia is a growth plate injury affecting the proximal tibia, typically occurring in children and adolescents. This fracture involves a separation through the growth plate (physis) with a metaphyseal fragment, disrupting bone development in the area.

Causes

Common causes include trauma from falls, sports injuries, or accidents where force is applied to the knee or lower leg. Direct impact, twisting motions, or axial loading can disrupt the growth plate, leading to this type of fracture.

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 knee or proximal tibia.
• Swelling and possible bruising near the affected area.
• Difficulty or reluctance to bear weight on the affected leg.
• Limited range of motion in the knee.

Diagnosis

Physical examination to assess pain, swelling, and range of motion. Imaging tests, such as X-rays, are typically used to confirm separation at the growth plate and identify the metaphyseal fragment. Additional imaging may be considered if the fracture pattern is unclear or if associated injuries are suspected.

Treatment Options

Treatment depends on fracture severity and displacement. Nonsurgical options include casting or bracing for stable fractures. Surgical intervention may be required for displaced fractures to realign the bone and stabilize the growth plate. Follow-up care focuses on monitoring healing and growth plate function.

Prognosis and Follow-Up

Prognosis is generally favorable with appropriate treatment, though long-term monitoring is important to assess growth plate function and potential limb length discrepancies. Regular follow-up appointments with imaging may be needed to evaluate bone development and alignment.

Complications

Potential complications include growth plate damage leading to limb length discrepancies or angular deformities, delayed union, or nonunion. Infection or nerve injury may occur with surgical intervention. Early detection and management reduce these risks.

Lifestyle & Prevention

Preventive measures include using proper protective equipment during sports, ensuring safe play environments, and teaching children safe movement techniques. Avoiding high-risk activities without supervision can reduce fracture likelihood.

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, increased swelling, redness). Prompt evaluation is critical to prevent complications and ensure proper healing.

Tips for Medical Coders

Document the unspecified nature of the tibia in the medical record, as this code is used when the side (right/left) is not specified. Ensure clinical documentation supports the Salter-Harris Type II fracture pattern, including growth plate involvement and metaphyseal fragment presence. Verify that no laterality is documented to justify the unspecified designation.
