S59.021 Salter-Harris Type II physeal fracture of lower end of ulna, right arm

Name of the Condition

• Salter-Harris Type II physeal fracture of lower end of ulna, right arm

Summary

This condition involves a fracture of the growth plate (physeal) at the lower end of the ulna bone, classified as Salter-Harris Type II. It typically affects children and adolescents, where the fracture extends through the physis (growth plate) and into the metaphysis. The injury may result from trauma to the forearm, particularly near the wrist joint.

Causes

Salter-Harris Type II physeal fractures often occur due to direct impact, such as a fall onto an outstretched hand, or from forceful twisting of the forearm. These injuries are common in activities involving sudden stops or collisions, where the growth plate is weaker than surrounding bone.

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 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.
• Pain management with medications or other therapies.
• Surgical intervention may be required for severe or displaced fractures.
• Physical therapy to restore strength and mobility after healing.

Prognosis and Follow-Up

Most Salter-Harris Type II fractures heal well with appropriate treatment, though outcomes depend on the severity of the injury and adherence to follow-up care. Regular monitoring is important to ensure proper healing and to address any potential complications. Follow-up appointments may include repeat imaging to assess progress.

Complications

• Premature closure of the growth plate, potentially leading to limb length discrepancy.
• Malunion or nonunion of the fracture.
• Nerve or blood vessel damage in severe cases.
• Chronic pain or stiffness in the wrist or forearm.

Lifestyle & Prevention

• Use protective gear during sports or activities with a high risk of falls.
• Ensure proper technique and training to reduce injury risk.
• Maintain bone health through a balanced diet and regular exercise.
• Avoid activities that place excessive stress on the wrist or 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, tingling, or coldness). Prompt evaluation is important to prevent complications and ensure proper treatment.

Tips for Medical Coders

This code specifies a Salter-Harris Type II physeal fracture of the lower end of the ulna in the right arm. Documentation should clearly indicate the fracture type, location, and laterality. Ensure the medical record supports the classification and any associated details, such as displacement or treatment, to justify the code assignment.
