S99.239A Salter-Harris Type III physeal fracture of phalanx of unspecified toe, initial encounter for closed fracture

Name of the Condition

• Salter-Harris Type III physeal fracture of phalanx of unspecified toe, initial encounter for closed fracture

Summary

This condition involves a fracture affecting the growth plate (physis) of an unspecified toe phalanx, classified as Salter-Harris Type III. This type of fracture extends through the growth plate and into the epiphysis (the end of the bone), typically occurring in children or adolescents. Proper evaluation is necessary to ensure healing and normal growth.

Causes

Direct trauma or injury to the toe, such as falls, sports-related impacts, or accidents, can disrupt the growth plate. Sudden force applied to the phalanges, including stubbing, crushing, or twisting, may lead to this type of fracture.

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 toes or surrounding structures may increase vulnerability.
• Poor footwear: Shoes that do not fit properly or lack support can increase toe injury risk.

Symptoms

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

Diagnosis

Physical examination to assess pain, swelling, and function is typically performed. Imaging, such as X-rays, may be used to confirm the fracture type and extent, focusing on the growth plate and epiphysis.

Treatment Options

Treatment may include immobilization with a splint or cast to stabilize the fracture. Pain management and activity modification are often recommended. In some cases, surgical intervention may be necessary to realign the bone.

Prognosis and Follow-Up

With proper treatment, most Salter-Harris Type III fractures heal well, but regular follow-up is important to monitor growth and alignment. Long-term outcomes depend on the severity of the injury and adherence to treatment plans.

Complications

Potential complications include growth disturbances, malunion, or nonunion of the fracture. Infection or nerve damage may occur in severe cases.

Lifestyle & Prevention

Wearing properly fitting, supportive footwear can reduce toe injury risk. Avoiding high-impact activities without proper protection and practicing safe movement techniques may help prevent fractures.

When to Seek Professional Help

Seek medical attention if there is severe pain, swelling, or inability to bear weight. Immediate care is recommended for visible deformity or signs of infection, such as redness or fever.

Tips for Medical Coders

Document the specific toe (if known) and whether the fracture is open or closed. For this code, specify "initial encounter" and "closed fracture" as indicated. Ensure documentation supports the Salter-Harris Type III classification and the affected phalanx.
