S59.132A Salter-Harris Type III physeal fracture of upper end of radius, left arm, initial encounter for closed fracture

Name of the Condition

• Salter-Harris Type III physeal fracture of upper end of radius, left arm, initial encounter for closed fracture

Summary

This condition involves a Salter-Harris Type III fracture of the growth plate (physeal) at the upper end of the radius bone in the left arm. The injury extends through the physis and into the epiphysis, typically affecting children and adolescents. It is classified as an initial encounter for a closed fracture, meaning the skin remains intact. Trauma to the forearm, particularly near the elbow, is the usual cause.

Causes

Salter-Harris Type III physeal fractures often result from direct impact, such as a fall onto an outstretched hand, or forceful twisting of the forearm. These injuries may occur during sports, play, or accidents involving sudden force to the elbow or forearm.

Risk Factors

• Children and adolescents are at higher risk due to the presence of growth plates.
• Participation in activities with a high risk of falls or impacts, such as contact sports or playground activities.
• Pre-existing conditions affecting bone strength, such as metabolic bone disorders.

Symptoms

• Pain and swelling near the elbow or forearm.
• Difficulty moving the wrist or hand.
• Tenderness or visible deformity at the injury site.
• Numbness or tingling if nerves are compressed.

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, such as CT or MRI, may be used if the fracture involves the joint surface or if other injuries are suspected.

Treatment Options

Treatment depends on the fracture's severity and displacement. Nonsurgical options include immobilization with a cast or splint to allow healing. Surgical intervention may be necessary for displaced fractures to realign the bone and restore joint function. Physical therapy is often recommended during recovery to regain strength and mobility.

Prognosis and Follow-Up

Prognosis is generally favorable with appropriate treatment, though outcomes depend on the fracture's severity and alignment. Regular follow-up appointments are necessary to monitor healing and assess for complications. Long-term monitoring may be required to ensure normal growth and joint function.

Complications

Potential complications include growth plate damage leading to limb length discrepancy or angular deformity, joint stiffness, or arthritis. Nerve or blood vessel injury may occur, particularly with severe fractures. Incomplete healing or malunion can also result in functional limitations.

Lifestyle & Prevention

Preventive measures include using protective gear during sports, ensuring safe play environments, and teaching proper falling techniques. Maintaining bone health through adequate nutrition, such as calcium and vitamin D, may support overall bone strength. Avoiding high-risk activities without proper supervision can reduce injury likelihood.

When to Seek Professional Help

Seek immediate medical attention if there is severe pain, swelling, deformity, or inability to move the arm. Numbness, tingling, or coldness in the hand or fingers may indicate nerve or vascular injury and requires urgent evaluation. Persistent pain or difficulty using the arm after an injury should also prompt a healthcare visit.

Tips for Medical Coders

Document the fracture's location (left arm), type (Salter-Harris III), and encounter details (initial, closed) to ensure accurate coding. Include clinical notes on fracture displacement, treatment provided, and any associated injuries. Verify that the code aligns with the specific anatomical site and fracture characteristics documented in the record.
