S59.221S Salter-Harris Type II physeal fracture of lower end of radius, right arm, sequela

Name of the Condition

• Salter-Harris Type II physeal fracture of lower end of radius, right arm, sequela

Summary

This condition represents a Salter-Harris Type II physeal fracture of the lower end of the radius in the right arm, classified as a sequela. It indicates long-term effects or complications following the initial injury, such as residual deformity, functional impairment, or chronic pain. The fracture involves the growth plate (physeal) and metaphysis, typically affecting children and adolescents, with the sequela reflecting ongoing consequences of the healed fracture.

Causes

Salter-Harris Type II physeal fractures result from trauma to the forearm, often due to falls onto an outstretched hand or forceful twisting. The sequela arises from incomplete healing, malunion, or persistent damage to the growth plate, leading to lasting structural or functional changes in the affected area.

Risk Factors

• Children and adolescents, due to open growth plates.
• High-impact activities or sports increasing fracture risk.
• Inadequate initial treatment or delayed healing.
• Genetic or metabolic bone conditions affecting recovery.

Symptoms

• Chronic pain or discomfort in the wrist or forearm.
• Reduced range of motion or stiffness.
• Visible deformity or misalignment of the wrist.
• Occasional swelling or tenderness with activity.

Diagnosis

Diagnosis involves a physical exam to assess function and deformity, plus imaging (X-rays, CT, or MRI) to evaluate residual bone alignment, growth plate integrity, or signs of chronic changes. Clinical correlation with the patient’s history of prior fracture is essential.

Treatment Options

Treatment focuses on managing symptoms and functional limitations. Options may include physical therapy to improve mobility, pain management, orthotic devices for support, or surgical correction for significant deformity. Management is tailored to the severity of the sequela and patient needs.

Prognosis and Follow-Up

Prognosis depends on the extent of growth plate damage and initial injury. Some patients experience minimal long-term effects, while others may have persistent stiffness or deformity. Regular follow-up with an orthopedic specialist monitors growth, function, and the need for interventions.

Complications

• Growth disturbances or limb length discrepancy.
• Chronic arthritis or joint stiffness.
• Persistent pain or reduced grip strength.
• Aesthetic concerns from visible deformity.

Lifestyle & Prevention

• Avoid high-risk activities to prevent reinjury.
• Use protective gear during sports.
• Maintain strength and flexibility through exercises.
• Follow-up care to address emerging issues early.

When to Seek Professional Help

Seek care if symptoms worsen, new pain or deformity develops, or functional limitations impact daily activities. Prompt evaluation helps address complications and adjust management.

Tips for Medical Coders

Document the sequela clearly, noting the history of the prior Salter-Harris Type II fracture and its long-term effects. Ensure clinical correlation supports the sequela diagnosis, as coding requires evidence of residual impairment from the original injury.
