S72.362N Displaced segmental fracture of shaft of left femur, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with nonunion

Name of the Condition

• Displaced Segmental Fracture of Shaft of Left Femur, Subsequent Encounter for Open Fracture Type IIIA, IIIB, or IIIC with Nonunion

Summary

A displaced segmental fracture of the left femur shaft involves a break in the long, central portion of the thigh bone with two separate fracture lines, creating a free-floating bone segment. The term "displaced" indicates the bone fragments are not aligned, and "open fracture type IIIA, IIIB, or IIIC" means the fracture penetrates the skin with severe soft tissue damage. "Nonunion" refers to the failure of the bone to heal properly after an extended period. This condition requires evaluation to determine the extent of displacement, soft tissue injury, and appropriate management for nonunion.

Causes

Such fractures typically result from high-impact trauma, such as motor vehicle accidents, falls from significant heights, or direct blows to the thigh. Rotational forces or axial loading (e.g., during sports or industrial injuries) can also cause this type of break. Nonunion may occur due to inadequate immobilization, poor blood supply, infection, or other factors that impede healing.

Risk Factors

• Participation in high-impact sports or activities.
• Osteoporosis or other bone-weakening conditions.
• Advanced age, due to decreased bone density.
• Prior history of fractures or bone abnormalities.
• Trauma or accidents involving significant force.
• Smoking or poor nutrition, which can impair bone healing.
• Infection at the fracture site.

Symptoms

• Persistent pain at the fracture site, even after initial treatment.
• Swelling, bruising, or tenderness around the fracture site.
• Inability to bear weight on the affected leg.
• Visible deformity or shortening of the leg (in displaced fractures).
• Possible numbness or tingling if nerve involvement occurs.
• Delayed or absent healing signs (e.g., no callus formation on imaging).

Diagnosis

Physical examination to assess pain, swelling, and deformity, followed by imaging studies such as X-rays, CT scans, or MRI to evaluate fracture alignment, soft tissue damage, and signs of nonunion. Blood tests may be used to check for infection or nutritional deficiencies. Documentation should confirm the fracture type, nonunion status, and any associated complications.

Treatment Options

Treatment may include surgical intervention to realign and stabilize the fracture, such as internal fixation with plates, screws, or intramedullary nails. Bone grafting or electrical stimulation may be used to promote healing in cases of nonunion. Antibiotics or wound care may be necessary for open fractures. Physical therapy is often recommended to restore function and strength.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, soft tissue damage, and response to treatment. Nonunion may require additional interventions, and recovery can be prolonged. Regular follow-up with imaging and clinical assessments is essential to monitor healing and adjust treatment as needed.

Complications

• Infection at the fracture site.
• Nerve or blood vessel damage.
• Chronic pain or arthritis.
• Limb length discrepancy.
• Delayed or failed healing (nonunion).
• Need for additional surgeries.

Lifestyle & Prevention

• Avoid high-impact activities that risk injury.
• Maintain bone health through a balanced diet rich in calcium and vitamin D.
• Quit smoking, as it impairs bone healing.
• Use protective equipment during sports or work.
• Follow post-treatment guidelines for immobilization and weight-bearing restrictions.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, swelling, deformity, or inability to bear weight after a trauma. Contact your healthcare provider if symptoms worsen or if you notice signs of infection, such as fever, redness, or drainage from the wound.

Tips for Medical Coders

Document the fracture type (displaced segmental), laterality (left femur), encounter type (subsequent), open fracture classification (IIIA, IIIB, or IIIC), and nonunion status clearly. Ensure documentation supports the specific code S72.362N and aligns with clinical findings.
