S59.23 Salter-Harris Type III physeal fracture of lower end of radius

Name of the Condition

• Salter-Harris Type III physeal fracture of lower end of radius

Summary

This condition refers to a Salter-Harris Type III fracture involving the growth plate (physeal) at the lower end of the radius bone, typically affecting children and adolescents. The injury involves a fracture that extends through the growth plate and into the joint surface, often resulting 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.
• Surgical intervention may be required if the fracture involves significant joint displacement or instability.
• Physical therapy to restore strength and mobility after healing.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture and the accuracy of treatment. Regular follow-up appointments are necessary to monitor healing and assess for potential growth disturbances. Long-term outcomes are generally favorable with appropriate management.

Complications

• Growth plate damage leading to limb length discrepancy or angular deformity.
• Joint stiffness or arthritis due to involvement of the joint surface.
• Nonunion or malunion of the fracture.

Lifestyle & Prevention

• Use protective gear during sports or activities with fall risks.
• Ensure proper technique and conditioning to reduce injury likelihood.
• Maintain bone health through adequate nutrition and exercise.

When to Seek Professional Help

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

Tips for Medical Coders

Document the specific Salter-Harris Type III classification and confirm the fracture involves the lower end of the radius. Include details about the fracture's extent, such as joint involvement, to support accurate coding. Ensure clinical documentation aligns with the anatomical and injury specifics of the code.
