S49.142S Salter-Harris Type IV physeal fracture of lower end of humerus, left arm, sequela

Name of the Condition

• Salter-Harris Type IV physeal fracture of lower end of humerus, left arm, sequela (ICD-10 Code: S49.142S)

Summary

This code describes a Salter-Harris Type IV fracture involving the growth plate (physeal) at the lower end of the left humerus, with a sequela designation. Type IV fractures extend through the metaphysis, physis, and epiphysis, potentially disrupting both bone growth and joint stability. The sequela indicates the condition is a late effect of the fracture, such as chronic pain, deformity, or functional impairment resulting from the initial injury.

Causes

The primary cause is trauma to the elbow, typically from a fall onto an outstretched hand or a direct blow. High-impact activities, such as sports or accidents, can generate the force needed to cause this fracture. The sequela arises as a long-term consequence of the initial injury, reflecting persistent or residual effects.

Risk Factors

• Age (most common in children and adolescents with open growth plates)
• Participation in high-impact or contact sports
• Prior growth plate injuries or developmental abnormalities
• Inadequate initial treatment or healing complications

Symptoms

• Chronic pain or discomfort in the elbow or lower arm
• Persistent swelling or deformity
• Limited range of motion or joint stiffness
• Functional impairment, such as difficulty with daily activities
• Possible growth disturbances or limb length discrepancy

Diagnosis

Diagnosis involves a clinical evaluation of persistent symptoms and a review of the patient’s history of the initial fracture. Imaging, such as X-rays or MRI, may be used to assess residual bone or joint abnormalities. The sequela designation is applied when the condition is a direct result of the prior fracture and persists beyond the active healing phase.

Treatment Options

Treatment focuses on managing symptoms and addressing functional limitations. Options may include physical therapy to improve mobility, pain management, or surgical intervention for severe deformity or instability. The approach is tailored to the specific sequelae and the patient’s needs.

Prognosis and Follow-Up

Prognosis depends on the severity of the initial injury and the extent of residual damage. Some patients may experience long-term functional limitations, while others recover with minimal impact. Regular follow-up is important to monitor for complications and adjust treatment as needed.

Complications

• Chronic pain or arthritis
• Growth plate disturbances leading to limb length discrepancy
• Joint instability or deformity
• Reduced range of motion or functional impairment

Lifestyle & Prevention

• Avoid high-impact activities that risk re-injury
• Use protective gear during sports or physical activities
• Follow rehabilitation guidelines to optimize recovery
• Maintain regular medical check-ups to monitor for late effects

When to Seek Professional Help

Seek care if symptoms worsen, new pain or deformity develops, or functional limitations interfere with daily life. Prompt evaluation is important to address complications or adjust treatment plans.

Tips for Medical Coders

This code is used for a sequela of a Salter-Harris Type IV physeal fracture of the left humerus. Document the relationship between the current condition and the prior fracture, including the nature of the residual effects (e.g., chronic pain, deformity). Ensure the sequela is directly attributable to the initial injury and not a new or unrelated condition.
