S59.029S Salter-Harris Type II physeal fracture of lower end of ulna, unspecified arm, sequela

Name of the Condition

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

Summary

This condition represents a Salter-Harris Type II physeal fracture of the lower end of the ulna, with sequela indicating residual effects following the healing phase. It involves a fracture through the growth plate (physis) extending into the metaphysis, typically affecting children and adolescents. The sequela phase denotes long-term consequences or complications after the initial injury has healed.

Causes

Salter-Harris Type II physeal fractures result from trauma, such as falls onto an outstretched hand or forceful twisting of the forearm. The growth plate’s relative weakness compared to surrounding bone makes it susceptible to injury during high-impact activities. Sequela may arise from incomplete healing, malunion, or persistent functional impairment.

Risk Factors

• Children and adolescents due to open growth plates.
• Participation in contact sports or activities with fall risks.
• Prior fractures or bone disorders affecting healing.

Symptoms

• Chronic pain or discomfort in the forearm or wrist.
• Limited range of motion or stiffness.
• Visible deformity or growth disturbance.
• Numbness or weakness in the hand.

Diagnosis

Diagnosis involves clinical evaluation of residual symptoms, imaging (e.g., X-rays) to assess bone alignment and growth plate status, and review of prior treatment history. Sequela is confirmed when symptoms persist beyond the expected healing period, indicating lasting effects.

Treatment Options

Management focuses on addressing residual symptoms, such as physical therapy to improve function, pain management, or corrective surgery for severe deformities. Treatment is tailored to the specific sequela and functional impact.

Prognosis and Follow-Up

Prognosis depends on the severity of the initial injury and healing. Most patients recover with minimal long-term effects, but some may experience growth disturbances or arthritis. Regular follow-up monitors for complications and functional recovery.

Complications

• Growth plate damage leading to limb length discrepancy.
• Chronic pain or arthritis.
• Reduced mobility or strength.
• Nerve or vascular impairment.

Lifestyle & Prevention

• Avoid high-risk activities until fully healed.
• Use protective gear during sports.
• Maintain bone health with proper nutrition (e.g., calcium, vitamin D).
• Follow post-injury rehabilitation guidelines.

When to Seek Professional Help

Seek care if experiencing worsening pain, new deformity, or loss of function. Persistent numbness, swelling, or signs of infection also warrant evaluation.

Tips for Medical Coders

Document the sequela phase clearly, including evidence of residual effects (e.g., imaging, clinical notes) and the timeline since the initial injury. Ensure the code aligns with the patient’s current status and prior treatment history.
