S59.249 Salter-Harris Type IV physeal fracture of lower end of radius, unspecified arm

Name of the Condition

• Salter-Harris Type IV physeal fracture of lower end of radius, unspecified arm

Summary

This condition refers to a Salter-Harris Type IV fracture involving the growth plate (physeal) at the lower end of the radius bone in an unspecified arm. It typically affects children and adolescents, involving a fracture that extends through the metaphysis, physis, and epiphysis. The injury often results from trauma to the forearm near the wrist joint.

Causes

Salter-Harris Type IV 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 pattern and confirm the diagnosis.

Treatment Options

• Immobilization with a cast or splint to stabilize the fracture.
• Surgical intervention may be required for displaced fractures to realign the bone.
• Pain management with medications as needed.
• Physical therapy to restore strength and mobility after healing.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture and timely treatment. Most fractures heal well with proper care, but regular follow-up is essential to monitor growth plate function and prevent complications. Long-term outcomes may include normal function or, in some cases, growth disturbances.

Complications

• Growth plate damage leading to limb length discrepancy or angular deformity.
• Joint stiffness or reduced range of motion.
• Potential for arthritis in the affected wrist over time.
• Nonunion or malunion of the fracture.

Lifestyle & Prevention

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

When to Seek Professional Help

Seek immediate medical attention if there is severe pain, visible deformity, inability to move the wrist or hand, or signs of nerve or blood vessel injury (e.g., numbness, coldness, or discoloration).

Tips for Medical Coders

Document the affected arm (right, left, or unspecified) and confirm the fracture type as Salter-Harris Type IV. Ensure the code aligns with clinical documentation, noting the anatomical location (lower end of radius) and the physeal involvement. Verify that the fracture is not associated with other injuries or conditions that may require additional coding.
