S49.029 Salter-Harris Type II physeal fracture of upper end of humerus, unspecified arm

Name of the Condition

• Salter-Harris Type II physeal fracture of upper end of humerus, unspecified arm (ICD-10 Code: S49.029)

Summary

This code describes a Salter-Harris Type II fracture involving the growth plate (physeal) at the upper end of the humerus, the bone of the upper arm, with the arm side unspecified. This type of fracture occurs when the growth plate and a portion of the metaphysis (the area adjacent to the growth plate) separate from the rest of the bone, typically in children and adolescents due to the relative weakness of the physis during development.

Causes

Trauma, such as a fall onto an outstretched hand or a direct blow to the shoulder, is the primary cause. These injuries often occur during sports, play, or accidents involving forceful arm movement.

Risk Factors

• Age (most common in children and adolescents with open growth plates)
• Participation in high-impact sports or activities
• Prior growth plate injuries

Symptoms

• Pain and swelling at the shoulder or upper arm
• Limited range of motion
• Visible deformity in severe cases
• Difficulty moving the arm

Diagnosis

Diagnosis relies on a physical examination to assess pain, swelling, and range of motion, combined with imaging studies like X-rays to visualize the fracture and confirm its location at the growth plate. A detailed patient history, including the mechanism of injury, is also important.

Treatment Options

• Immobilization: A sling or cast may be used to stabilize the arm and allow healing.
• Pain management: Medications or other methods to control discomfort.
• Surgical intervention: May be required for severe or displaced fractures to realign the bone.
• Physical therapy: Often recommended during recovery to restore strength and mobility.

Prognosis and Follow-Up

Most Salter-Harris Type II fractures heal well with appropriate treatment, especially when diagnosed early. Follow-up care typically includes monitoring for proper healing and assessing for any long-term effects on growth or function. Regular check-ups may be needed to ensure the fracture heals without complications.

Complications

• Premature closure of the growth plate, potentially affecting limb length or alignment
• Chronic pain or stiffness
• Reduced range of motion
• Risk of re-injury if not fully healed

Lifestyle & Prevention

• Use protective gear during sports or activities with a risk of falls.
• Ensure proper supervision of children during play to minimize accident risks.
• Maintain overall bone health through a balanced diet and regular exercise.

When to Seek Professional Help

Seek immediate medical attention if there is severe pain, visible deformity, inability to move the arm, or signs of infection (e.g., fever, increased swelling, redness) after an injury.

Tips for Medical Coders

This code is specific to the Salter-Harris Type II physeal fracture of the upper humerus with the arm side unspecified. Documentation should clearly indicate the fracture type, location, and that the arm side is not specified to support accurate coding. Ensure the medical record includes details about the injury mechanism, clinical findings, and any imaging results to confirm the diagnosis.
