S99.122S Salter-Harris Type II physeal fracture of left metatarsal, sequela

Name of the Condition

• Salter-Harris Type II physeal fracture of left metatarsal, sequela

Summary

This condition represents the long-term effects (sequela) of a Salter-Harris Type II physeal fracture involving the left metatarsal. Type II fractures involve separation of the growth plate with a metaphyseal fragment. Sequela refers to residual impairments or complications persisting after the acute injury phase, such as chronic pain, deformity, or functional limitations. These outcomes require ongoing evaluation to manage symptoms and optimize recovery.

Causes

The sequela arises from the initial fracture, which typically results from direct trauma to the foot, such as falls, sports injuries, or accidents. High-energy forces disrupting the growth plate and surrounding bone can lead to incomplete healing, malunion, or avascular necrosis, contributing to lasting effects.

Risk Factors

• Age: Children and adolescents, as their growth plates are still developing and more prone to injury.
• High-impact activities: Participation in sports like running, jumping, or contact sports.
• Inadequate initial treatment: Improper immobilization or delayed care may increase the risk of complications.
• Severity of initial injury: More severe fractures are more likely to result in long-term sequelae.

Symptoms

• Chronic pain or discomfort in the left metatarsal area.
• Difficulty bearing weight or walking on the affected foot.
• Limited range of motion in the toes or midfoot.
• Visible deformity or swelling.
• Possible gait abnormalities.

Diagnosis

Diagnosis involves a clinical evaluation of persistent symptoms and a review of the initial injury history. Imaging, such as X-rays or MRI, may be used to assess residual bone alignment, healing, or associated complications like avascular necrosis. Functional assessments help determine the impact on daily activities.

Treatment Options

Treatment focuses on managing symptoms and improving function. Options may include physical therapy to restore mobility, orthotic devices for support, pain management, or surgical intervention for severe deformities. The approach is tailored to the specific sequelae and patient needs.

Prognosis and Follow-Up

Prognosis varies based on the severity of the initial injury and the extent of residual effects. Regular follow-up with a healthcare provider is essential to monitor for worsening symptoms or new complications. Long-term management may be necessary to address chronic pain or functional limitations.

Complications

• Chronic pain or arthritis in the affected joint.
• Deformity or malunion of the metatarsal.
• Avascular necrosis of the growth plate.
• Gait abnormalities or difficulty with weight-bearing.
• Reduced range of motion in the foot.

Lifestyle & Prevention

• Avoid high-impact activities that stress the foot.
• Use appropriate footwear for support and protection.
• Maintain a healthy weight to reduce stress on the foot.
• Follow post-injury rehabilitation guidelines to minimize long-term effects.

When to Seek Professional Help

Seek medical attention if symptoms worsen, new pain or swelling develops, or functional limitations increase. Prompt evaluation is important for managing complications and adjusting treatment as needed.

Tips for Medical Coders

This code is used for the sequela of a Salter-Harris Type II physeal fracture of the left metatarsal. Document the residual effects, such as chronic pain, deformity, or functional impairment, to support the sequela diagnosis. Ensure the initial injury and its timeline are clearly recorded, as the sequela must be linked to the prior fracture.
