S59.022 Salter-Harris Type II physeal fracture of lower end of ulna, left arm

Name of the Condition

• Salter-Harris Type II physeal fracture of lower end of ulna, left 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 wider part of the bone adjacent to the growth plate). 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, are used to confirm the fracture type and location. The left arm involvement is noted during assessment.

Treatment Options

Treatment depends on fracture severity and displacement. Options may include immobilization with a cast or splint, closed reduction (realignment without surgery), or surgical intervention for unstable fractures. Physical therapy may be recommended during recovery to restore function.

Prognosis and Follow-Up

Most Salter-Harris Type II fractures heal well with appropriate treatment, especially when diagnosed early. Follow-up care includes monitoring for proper healing and assessing for growth disturbances. Long-term outcomes are generally favorable, but regular check-ups may be needed to ensure normal bone development.

Complications

Potential complications include growth plate damage leading to limb length discrepancies or angular deformities, joint stiffness, or arthritis. Infection risk is low unless the fracture is open (not applicable here as the code specifies a closed fracture).

Lifestyle & Prevention

Preventive measures include using protective gear during sports, ensuring safe play environments, and teaching proper falling techniques. Avoiding high-risk activities without supervision can reduce fracture likelihood.

When to Seek Professional Help

Seek immediate medical attention if there is severe pain, inability to move the wrist or hand, visible deformity, or signs of nerve or blood vessel injury (e.g., numbness, coldness). Persistent pain or swelling after initial treatment also warrants evaluation.

Tips for Medical Coders

Document the left arm involvement and confirm the fracture is closed (no open wound) to align with the code. Ensure the Salter-Harris Type II classification is clearly stated in clinical notes, as this specific code requires precise anatomical and fracture-type details.
