S49.022S Salter-Harris Type II physeal fracture of upper end of humerus, left arm, sequela

Name of the Condition

• Salter-Harris Type II physeal fracture of upper end of humerus, left arm, sequela (ICD-10 Code: S49.022S)

Summary

This code describes a Salter-Harris Type II fracture involving the growth plate (physeal) at the upper end of the left humerus, representing a late effect or residual condition following the initial injury. This type of fracture occurs when the growth plate and a portion of the metaphysis separate from the rest of the bone, typically seen in children and adolescents due to the relative weakness of the physis during development. The "sequela" designation indicates the condition is a complication or residual effect persisting after the acute phase of the injury.

Causes

The underlying cause is a prior traumatic event, such as a fall onto an outstretched hand or a direct blow to the shoulder, which resulted in the initial Salter-Harris Type II fracture. The sequela arises as a consequence of the original injury and its healing process.

Risk Factors

• Age (most common in children and adolescents with open growth plates at the time of initial injury)
• Severity of the initial fracture
• Inadequate or delayed treatment of the original injury
• Participation in high-impact activities that stress the affected arm

Symptoms

• Chronic pain or discomfort in the shoulder or upper arm
• Residual swelling or deformity
• Limited range of motion or stiffness
• Possible growth disturbances or limb length discrepancy
• Functional impairment affecting daily activities

Diagnosis

Diagnosis involves a thorough clinical evaluation, including a detailed patient history to confirm the prior fracture and its treatment. Physical examination assesses residual symptoms, deformity, and functional limitations. Imaging studies, such as X-rays or MRI, may be used to evaluate the current state of the growth plate, bone healing, and any associated complications like malunion or growth arrest.

Treatment Options

Management focuses on addressing residual symptoms and functional limitations. Options may include physical therapy to improve range of motion and strength, pain management strategies, and, in severe cases, surgical intervention to correct deformity or address growth-related issues. Treatment is tailored to the specific sequelae and the patient's functional needs.

Prognosis and Follow-Up

Prognosis depends on the severity of the initial injury, the success of prior treatment, and the presence of complications. Regular follow-up is important to monitor for long-term effects, such as growth disturbances or arthritis. Outcomes range from full recovery with minimal residual symptoms to persistent functional limitations requiring ongoing management.

Complications

• Growth arrest or limb length discrepancy
• Chronic pain or arthritis
• Residual deformity or malunion
• Reduced range of motion or stiffness
• Functional impairment affecting daily activities

Lifestyle & Prevention

• Avoid high-impact activities that stress the affected arm until cleared by a healthcare provider.
• Engage in prescribed physical therapy to maintain or improve mobility and strength.
• Use protective equipment during sports or activities to prevent re-injury.
• Follow up regularly with a healthcare provider to monitor for late complications.

When to Seek Professional Help

Seek medical attention if you experience increasing pain, new swelling, decreased mobility, or signs of infection (e.g., redness, warmth) in the affected arm. Consult a healthcare provider for persistent functional limitations or concerns about growth-related issues.

Tips for Medical Coders

This code is used for the sequela (late effect) of a Salter-Harris Type II physeal fracture of the upper end of the left humerus. Document the relationship to the initial injury, including the time elapsed since the acute event and any residual symptoms or complications. Ensure the code is reported only after the acute phase of the injury has resolved and the condition is stable or chronic.
