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

Name of the Condition

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

Summary

This condition refers to a Salter-Harris Type II fracture involving the growth plate (physeal) at the lower end of the radius bone in the right arm, typically affecting children and adolescents. The injury involves a fracture through the growth plate and metaphysis, often resulting from trauma to the forearm near the wrist joint.

Causes

Salter-Harris Type II physeal fractures commonly occur due to direct impact, such as a fall onto an outstretched hand, or forceful twisting of the forearm. These injuries are frequently associated with activities involving sudden stops, collisions, or high-impact forces.

Risk Factors

• Children and adolescents are at higher risk due to the presence of growth plates.
• Participation in contact sports or activities with a high likelihood of falls increases risk.
• Certain genetic or metabolic conditions affecting bone development may also elevate susceptibility.

Symptoms

• Pain and swelling near the wrist or forearm.
• Difficulty moving the wrist or hand.
• Visible deformity or bruising around the affected area.
• Tenderness to touch at the fracture site.

Diagnosis

Physical examination by a healthcare professional to assess pain, swelling, and range of motion. Imaging tests, especially X-rays, to visualize the fracture and determine its extent. Additional imaging (e.g., MRI) may be used if the fracture is not clearly visible on X-rays.

Treatment Options

• Immobilization using a cast or splint to stabilize the fracture.
• Pain management with medications or other therapies.
• Surgical intervention may be required for severe or displaced fractures.
• Physical therapy to restore strength and mobility after healing.

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 bone growth and alignment. Long-term outcomes depend on the severity of the injury and adherence to treatment plans.

Complications

• Premature closure of the growth plate, potentially leading to limb length discrepancies.
• Malunion or nonunion of the fracture.
• Chronic pain or stiffness in the wrist or forearm.
• Nerve or blood vessel damage in severe cases.

Lifestyle & Prevention

• Use protective gear during sports or high-risk activities.
• Ensure proper technique and supervision in physical activities.
• Maintain bone health through adequate nutrition and exercise.
• Avoid falls by using safety measures in environments with slippery surfaces.

When to Seek Professional Help

Seek immediate medical attention if experiencing severe pain, visible deformity, inability to move the wrist or hand, or signs of infection (e.g., fever, increased swelling, redness).

Tips for Medical Coders

Document the specific side (right arm) and confirm the Salter-Harris Type II classification. Ensure clinical documentation supports the fracture type and location to justify code assignment. Note any associated injuries or complications that may require additional coding.
