S59.232 Salter-Harris Type III physeal fracture of lower end of radius, left arm

Name of the Condition

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

Summary

This condition involves a Salter-Harris Type III fracture of the growth plate (physeal) at the lower end of the left radius bone, typically affecting children and adolescents. The injury includes a fracture through the growth plate and extends 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 confirm the type and extent of the injury.

Treatment Options

• Immobilization with a cast or splint to stabilize the fracture.
• Closed reduction (manual realignment) if the fracture is displaced.
• Surgical intervention for severe or unstable fractures to restore joint alignment.
• Pain management and physical therapy during recovery.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture and timely treatment. Most heal well with proper care, but follow-up imaging may be needed to monitor growth plate integrity. Long-term outcomes are generally favorable with appropriate management.

Complications

• Growth plate damage leading to limb length discrepancy or angular deformity.
• Joint stiffness or reduced range of motion.
• 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 technique and supervision in physical activities.
• Maintain bone health with adequate nutrition (e.g., calcium, vitamin D).
• Avoid falls by using safety measures in environments prone to slips or trips.

When to Seek Professional Help

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

Tips for Medical Coders

Document the laterality (left arm) and confirm the fracture type (Salter-Harris Type III) and location (lower end of radius). Ensure the encounter type and fracture status (e.g., closed) are clearly specified in the record for accurate coding.
