S59.232A Salter-Harris Type III physeal fracture of lower end of radius, left arm, initial encounter for closed fracture

Name of the Condition

• Salter-Harris Type III physeal fracture of lower end of radius, left 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 left 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 confirm the Salter-Harris Type III classification. Additional imaging, such as CT or MRI, may be used to evaluate joint involvement or complex fractures.

Treatment Options

• Immobilization with a cast or splint to stabilize the fracture and allow healing.
• Closed reduction (manual realignment) if the fracture is displaced, followed by casting.
• Surgical intervention for severely displaced fractures or those involving joint surfaces, which may include internal fixation with pins or screws.
• Pain management with medications and activity modification during recovery.

Prognosis and Follow-Up

Prognosis depends on the accuracy of fracture reduction and the extent of joint involvement. Most heal well with proper treatment, but there is a risk of growth plate disturbance or long-term joint issues. Follow-up appointments monitor healing, range of motion, and potential complications. Physical therapy may be recommended to restore function.

Complications

• Growth plate damage leading to limb length discrepancy or angular deformity.
• Premature closure of the growth plate.
• Post-traumatic arthritis due to joint surface involvement.
• Stiffness or reduced range of motion in the wrist.

Lifestyle & Prevention

• Use protective gear during sports or high-risk activities.
• Ensure proper technique and supervision in activities with fall risks.
• Maintain bone health through adequate nutrition, including calcium and vitamin D.
• Avoid activities that place excessive stress on the wrist until fully healed.

When to Seek Professional Help

Seek immediate medical attention for severe pain, visible deformity, inability to move the wrist, or signs of infection (e.g., fever, increased swelling, redness). Follow up with a healthcare provider if symptoms worsen or do not improve with initial treatment.

Tips for Medical Coders

Document the specific anatomical site (left arm), fracture type (Salter-Harris Type III), encounter type (initial), and fracture status (closed). Include details on diagnostic imaging, treatment provided, and any complications. Ensure documentation supports the closed fracture classification and initial encounter context.
