S59.032 Salter-Harris Type III physeal fracture of lower end of ulna, left arm

Name of the Condition

• Salter-Harris Type III physeal fracture of lower end of ulna, left 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 left 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, are used to confirm the fracture type and extent, focusing on the growth plate and epiphysis involvement.

Treatment Options

Treatment may include immobilization with a cast or splint to allow healing, followed by gradual rehabilitation. Surgical intervention might be necessary if the fracture involves joint displacement or instability. Pain management and activity modification are also part of the care plan.

Prognosis and Follow-Up

Prognosis depends on the fracture’s alignment and treatment. Most heal well with proper care, but regular follow-up is needed to monitor growth plate function and joint health. Long-term outcomes are generally favorable with appropriate management.

Complications

Potential complications include growth plate damage leading to limb length discrepancies, joint stiffness, or arthritis. Incomplete healing or malunion may require additional interventions.

Lifestyle & Prevention

Avoid high-risk activities without proper protection. Use wrist guards during sports, and ensure safe play environments to reduce fall risks. Prompt medical attention for injuries can prevent complications.

When to Seek Professional Help

Seek care if there is severe pain, swelling, or inability to move the wrist after an injury. Immediate evaluation is necessary for suspected fractures to ensure proper diagnosis and treatment.

Tips for Medical Coders

Document the fracture’s location (lower end of ulna, left arm), type (Salter-Harris III), and any associated details (e.g., open/closed, encounter type) to support accurate coding. Ensure clinical documentation aligns with the specific code’s requirements for laterality and fracture characteristics.
