S59.031 Salter-Harris Type III physeal fracture of lower end of ulna, right arm

Name of the Condition

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

Summary

This condition involves a Salter-Harris Type III fracture of the growth plate (physeal) at the lower end of the ulna bone in the right arm. It typically affects children and adolescents, where the fracture extends through the physis (growth plate) and into the epiphysis, potentially disrupting joint surfaces. 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 involves joint displacement or instability.
• Pain management and physical therapy to restore function after healing.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture and timely treatment. Most cases heal well with proper immobilization, but follow-up imaging may be needed to monitor growth plate alignment. Long-term monitoring is important to assess for potential growth disturbances or joint issues.

Complications

• Growth plate damage leading to limb length discrepancy or angular deformity.
• Joint stiffness or arthritis if the fracture involves the articular surface.
• Nerve or vascular injury in severe cases.

Lifestyle & Prevention

• Use protective gear during sports or high-risk activities.
• Ensure proper technique and supervision in activities involving falls or impacts.
• 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 nerve/vascular compromise (e.g., numbness, coldness).

Tips for Medical Coders

Document the specific Salter-Harris Type III classification, right arm involvement, and any associated injuries or treatments. Ensure the fracture is clearly described as involving the epiphysis to support accurate coding.
