S59.231A Salter-Harris Type III physeal fracture of lower end of radius, right arm, initial encounter for closed fracture

Name of the Condition

• Salter-Harris Type III physeal fracture of lower end of radius, right arm, initial encounter for closed fracture

Summary

This condition involves a Salter-Harris Type III fracture of the growth plate (physeal) at the lower end of the right radius bone, occurring during the initial encounter for a closed fracture. The injury extends through the growth plate and into the joint surface, typically affecting children and adolescents. It results from trauma to the forearm near the wrist joint.

Causes

Salter-Harris Type III 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.
• Tenderness to touch at the fracture site.
• Possible visible deformity or bruising around the affected area.

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 interventions.
• Surgical intervention may be required for displaced fractures to realign the bone and joint surface.
• Physical therapy to restore strength and mobility after healing.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture and proper treatment. Most cases heal well with appropriate care, but regular follow-up is necessary to monitor growth plate function and joint alignment. Long-term outcomes may include normal function or, in some cases, mild limitations if the growth plate is affected.

Complications

• Growth plate disturbance leading to limb length discrepancy or angular deformity.
• Joint stiffness or reduced range of motion.
• Arthritis in the affected joint over time.
• Nerve or blood vessel damage in severe cases.

Lifestyle & Prevention

• Use protective gear during sports or high-risk activities.
• Ensure proper supervision for children during play.
• Maintain bone health through adequate nutrition, including calcium and vitamin D.
• Avoid activities with a high risk of falls or direct trauma to the wrist.

When to Seek Professional Help

Seek immediate medical attention if there is severe pain, swelling, deformity, or inability to move the wrist or hand after an injury. Prompt evaluation is important to prevent complications and ensure proper treatment.

Tips for Medical Coders

Document the specific type of fracture (Salter-Harris Type III), the affected bone (lower end of radius), the side (right arm), and the encounter type (initial for closed fracture). Ensure clinical documentation supports the fracture details, including whether the fracture is closed and the exact location, to accurately assign the code.
