The ICD-10 code S99.139 refers to a Salter-Harris Type III physeal fracture of an unspecified metatarsal. This classification is crucial for accurately diagnosing and coding pediatric fractures, particularly those affecting the growth plates in children and adolescents.

Understanding Salter-Harris Fractures

What are Salter-Harris Fractures?

Salter-Harris fractures are a specific type of fracture that involves the growth plate (physeal plate) in children. These fractures are categorized into five types (I to V) based on the involvement of the growth plate and metaphysis:

• Type I: Fracture through the growth plate, sparing the metaphysis.
• Type II: Fracture through the growth plate and metaphysis, sparing the epiphysis.
• Type III: Fracture through the growth plate and epiphysis, sparing the metaphysis.
• Type IV: Fracture through the metaphysis, growth plate, and epiphysis.
• Type V: Compression fracture of the growth plate.

Salter-Harris Type III Fracture

A Type III fracture specifically involves the growth plate and extends into the epiphysis, which can potentially affect future growth and development of the bone. This type of fracture is significant because it can lead to complications such as growth disturbances if not properly managed.

Clinical Presentation

Symptoms

Patients with a Salter-Harris Type III fracture of the metatarsal may present with:

• Localized pain: Typically at the site of the fracture.
• Swelling: Around the affected metatarsal.
• Bruising: May be present depending on the severity of the injury.
• Difficulty bearing weight: Patients often have trouble walking or putting weight on the affected foot.

Diagnosis

Diagnosis is primarily made through:

• Clinical examination: Assessing the range of motion, tenderness, and swelling.
• Imaging studies: X-rays are the standard imaging modality used to confirm the fracture and assess its type. In some cases, MRI may be utilized for further evaluation, especially if the fracture is not clearly visible on X-rays.

Treatment

Management Strategies

The treatment for a Salter-Harris Type III fracture typically involves:

• Immobilization: Using a cast or splint to stabilize the fracture.
• Pain management: Administering analgesics to manage pain.
• Surgical intervention: In some cases, surgery may be required to realign the bones and stabilize the growth plate, especially if there is significant displacement.

Follow-Up Care

Regular follow-up is essential to monitor healing and ensure that there are no complications affecting growth. This may include repeat imaging studies to assess the healing process.

Conclusion

The ICD-10 code S99.139 is critical for accurately documenting a Salter-Harris Type III physeal fracture of an unspecified metatarsal.

Signs and Symptoms

Clinical Signs

• Swelling and Bruising: Localized swelling and bruising around the metatarsal region are common, indicating soft tissue injury associated with the fracture[8].
• Deformity: In some cases, there may be visible deformity of the foot, particularly if the fracture is displaced.
• Tenderness: Palpation of the affected area typically reveals tenderness over the metatarsal involved, especially at the site of the fracture.

Symptoms

• Pain: Patients often report significant pain in the foot, which may worsen with movement or weight-bearing activities. The pain is usually sharp and localized to the metatarsal region[7].
• Difficulty Walking: Due to pain and instability, children may exhibit difficulty walking or may refuse to bear weight on the affected foot.
• Limited Range of Motion: There may be a noticeable reduction in the range of motion of the toes and foot, particularly if the fracture involves the joint surface.

Diagnostic Considerations

Imaging

• X-rays: Standard radiographs are the primary imaging modality used to diagnose Salter-Harris Type III fractures. X-rays will typically show the fracture line extending through the physis and into the joint[5].
• MRI or CT Scans: In cases where the fracture is not clearly visible on X-rays or if there is concern for associated injuries, advanced imaging may be warranted.

Management and Prognosis

Treatment Approaches

• Conservative Management: Non-displaced fractures may be treated conservatively with rest, immobilization, and analgesics[4].
• Surgical Intervention: Displaced fractures or those involving significant joint involvement may require surgical fixation to ensure proper alignment and healing.

Prognosis

The prognosis for Salter-Harris Type III fractures is generally good if appropriately managed. However, there is a risk of complications such as growth disturbances or joint dysfunction, particularly if the fracture is not recognized and treated promptly[6][8].
