S99.131 Salter-Harris Type III physeal fracture of right metatarsal

Name of the Condition

• Salter-Harris Type III physeal fracture of right metatarsal

Summary

This condition involves a Salter-Harris Type III fracture affecting the growth plate (physis) of the right metatarsal bone. Type III fractures extend from the joint surface through the epiphysis and into the growth plate, potentially disrupting both bone growth and joint integrity. These injuries typically occur in children or adolescents with active growth plates and require careful evaluation to guide treatment and prevent long-term complications.

Causes

Direct trauma or injury to the foot, such as falls, sports-related impacts, or accidents, can disrupt the growth plate. Sudden force applied to the metatarsals, including twisting or direct blows, may lead to this type of fracture. The injury often results from high-energy events that stress the developing bone structure.

Risk Factors

• Age: Children and adolescents, as their growth plates are still developing and more susceptible to injury.
• High-impact activities: Participation in sports like running, jumping, or contact sports.
• Previous injuries: Prior damage to the metatarsals or surrounding structures may increase vulnerability.

Symptoms

• Pain and swelling localized to the metatarsal area.
• Difficulty bearing weight or walking on the affected foot.
• Limited range of motion in the toes or midfoot.
• Visible bruising or deformity in severe cases.

Diagnosis

Physical examination to assess pain, swelling, and functional limitations. Imaging tests, such as X-rays or MRI, to evaluate the fracture and growth plate involvement, including assessment of joint surface disruption.

Treatment Options

• Immobilization with a cast or brace
• Surgical intervention for displaced fractures to restore joint alignment
• Pain management and activity modification during healing

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture and timely treatment. Regular follow-up with imaging may be needed to monitor growth plate healing and joint integrity. Long-term monitoring for potential growth disturbances or arthritis is important.

Complications

• Growth plate damage leading to limb length discrepancy or angular deformity
• Post-traumatic arthritis due to joint surface involvement
• Nonunion or malunion of the fracture

Lifestyle & Prevention

• Use appropriate protective footwear during sports or high-impact activities.
• Avoid activities that place excessive stress on the feet until cleared by a healthcare provider.
• Maintain overall bone health through balanced nutrition and regular exercise.

When to Seek Professional Help

Seek immediate medical attention for severe pain, inability to bear weight, visible deformity, or signs of infection (e.g., redness, fever). Follow up with a healthcare provider if symptoms worsen or do not improve with initial treatment.

Tips for Medical Coders

Document the specific Salter-Harris Type III classification and right metatarsal involvement clearly. Include details on fracture displacement, joint involvement, and treatment approach to support accurate coding. Ensure documentation aligns with clinical findings and imaging results.
