S99.132A Salter-Harris Type III physeal fracture of left metatarsal, initial encounter for closed fracture

Name of the Condition

• Salter-Harris Type III physeal fracture of left metatarsal, initial encounter for closed fracture

Summary

This condition involves a Salter-Harris Type III fracture affecting the growth plate (physis) of the left metatarsal bone. Type III fractures extend from the joint surface through the epiphysis and into the growth plate, potentially disrupting 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. The "initial encounter for closed fracture" indicates this is the first presentation of a fracture without an open wound.

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.
• Possible bruising or deformity at the injury site.

Diagnosis

Diagnosis typically involves a physical examination to assess pain, swelling, and range of motion. Imaging studies, such as X-rays, are used to confirm the fracture type and assess joint involvement. The "closed fracture" status is determined by the absence of an open wound or communication with the fracture site.

Treatment Options

Treatment may include immobilization with a cast or splint to allow healing, followed by gradual weight-bearing as tolerated. Surgical intervention may be necessary if the fracture involves joint displacement or instability. Pain management and physical therapy are often part of the recovery process.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture and timely treatment. Proper alignment and healing of the growth plate are critical to prevent growth disturbances or joint issues. Follow-up appointments monitor healing progress and may include repeat imaging to ensure proper recovery.

Complications

Potential complications include growth plate damage leading to limb length discrepancies, joint stiffness, or arthritis. Incomplete healing or malunion may require additional intervention.

Lifestyle & Prevention

Avoid high-impact activities until cleared by a healthcare provider. Use appropriate footwear and protective gear during sports. Strengthening exercises and proper warm-ups may reduce injury risk.

When to Seek Professional Help

Seek immediate care for severe pain, inability to bear weight, visible deformity, or signs of infection (e.g., redness, fever). Prompt evaluation is essential to prevent complications.

Tips for Medical Coders

Document the specific metatarsal involved (left), fracture type (Salter-Harris III), encounter type (initial), and fracture status (closed). Ensure clinical notes support the "closed" designation and specify the left side to align with the code.
