S59.242 Salter-Harris Type IV physeal fracture of lower end of radius, left arm

Name of the Condition

• Salter-Harris Type IV physeal fracture of lower end of radius, left 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 the left 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.
• Closed reduction (manual realignment) if the bone is displaced.
• Surgical intervention for severe or unstable fractures to restore 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 growth plate damage may affect future bone development. Regular follow-up appointments monitor healing and function.

Complications

• Premature closure of the growth plate, leading to limb length discrepancy.
• Malunion or nonunion of the fracture.
• Joint stiffness or reduced range of motion.
• Increased risk of future fractures in the affected area.

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).

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).

Tips for Medical Coders

Document the laterality (left arm) and fracture type (Salter-Harris Type IV) clearly. Include details on the encounter type (e.g., initial, subsequent) and fracture status (open/closed) if applicable. Ensure clinical documentation supports the specific code selection.
