S72.362K Displaced segmental fracture of shaft of left femur, subsequent encounter for closed fracture with nonunion

Name of the Condition

• Displaced Segmental Fracture of Shaft of Left Femur, Subsequent Encounter for Closed Fracture 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, "closed" means the fracture does not penetrate the skin, and "nonunion" signifies the fracture has failed to heal properly after an expected period. This condition requires evaluation to determine the extent of displacement, healing status, and appropriate management.

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 develop due to inadequate immobilization, poor blood supply, infection, or excessive movement at the fracture site.

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 healing.
• Certain medical conditions (e.g., diabetes, vascular disease) that affect bone repair.

Symptoms

• Persistent or recurrent pain at the fracture site.
• Swelling, bruising, or tenderness around the fracture area.
• 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.
• Lack of improvement in pain or function over time, suggesting nonunion.

Diagnosis

Physical examination to assess pain, swelling, and deformity. Imaging studies, such as X-rays, CT scans, or MRI, to evaluate fracture alignment, healing progress, and signs of nonunion (e.g., persistent fracture line, lack of callus formation). Additional tests may be ordered to rule out infection or assess bone density.

Treatment Options

Treatment depends on the severity of displacement and nonunion. Options may include surgical intervention (e.g., internal fixation with plates, screws, or rods; bone grafting to stimulate healing) or non-surgical management (e.g., prolonged immobilization, physical therapy). Pain management and rehabilitation are often necessary to restore function.

Prognosis and Follow-Up

Prognosis varies based on the extent of nonunion, overall health, and treatment response. Follow-up care typically involves regular imaging to monitor healing and functional assessments. Long-term outcomes may include persistent pain, limited mobility, or the need for additional interventions if healing does not occur.

Complications

• Chronic pain or discomfort.
• Limited range of motion or mobility.
• Infection (if surgical intervention is required).
• Nerve or vascular damage.
• Malunion (improper healing in a misaligned position).
• Need for additional surgeries if nonunion persists.

Lifestyle & Prevention

• Avoid high-impact activities that risk injury.
• Maintain bone health through a balanced diet rich in calcium and vitamin D.
• Engage in weight-bearing exercises to strengthen bones (as advised by a healthcare provider).
• Use protective equipment during sports or activities with fall risks.
• Quit smoking and limit alcohol, as both can impair bone healing.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, swelling, deformity, or inability to bear weight after an injury. Contact a healthcare provider if pain persists, worsens, or if you notice signs of infection (e.g., redness, warmth, fever) at the fracture site.

Tips for Medical Coders

Document the encounter as a subsequent visit for a closed fracture with nonunion. Ensure clinical notes specify the fracture type (displaced segmental), location (left femur shaft), and healing status (nonunion) to support accurate coding. Verify that the encounter aligns with the definition of "subsequent" (follow-up care after initial treatment) and that the fracture remains closed (no skin penetration).
