S59.03 Salter-Harris Type III physeal fracture of lower end of ulna

Name of the Condition

• Salter-Harris Type III physeal fracture of lower end of ulna

Summary

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

Causes

Salter-Harris Type III 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.
• Surgical intervention may be required if the fracture is displaced or involves joint surfaces.
• Pain management with medications as needed.
• Physical therapy to restore strength and mobility after healing.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture and treatment. Most heal well with proper care, but follow-up imaging may be needed to monitor growth plate alignment. Regular check-ups ensure proper healing and address any complications early.

Complications

• Growth plate damage leading to limb length discrepancy or deformity.
• Joint stiffness or reduced range of motion.
• Infection (if surgical intervention is required).
• Nerve or blood vessel injury in severe cases.

Lifestyle & Prevention

• Use protective gear during sports or activities with fall risks.
• Ensure proper technique and supervision in physical activities.
• Maintain bone health through balanced nutrition and regular exercise.

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 fracture type (Salter-Harris Type III) and location (lower end of ulna) clearly. Include details on displacement, treatment, and any associated injuries to support accurate coding. Ensure documentation aligns with clinical findings and imaging results.
