S72.334K Nondisplaced oblique fracture of shaft of right femur, subsequent encounter for closed fracture with nonunion

Name of the Condition

• Nondisplaced Oblique Fracture of Shaft of Right Femur, Subsequent Encounter for Closed Fracture with Nonunion

Summary

A nondisplaced oblique fracture of the shaft of the right femur is a break in the long, central portion of the thigh bone where the fracture line runs at an angle, and the bone fragments remain aligned. This code specifies a subsequent encounter for a closed fracture with nonunion, indicating the fracture has not healed properly after prior treatment. Nonunion refers to a fracture that fails to unite within the expected timeframe, typically requiring additional management.

Causes

Such fractures often 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 to the fracture site, infection, or underlying conditions like diabetes or smoking.

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.
• Factors that impair healing, such as smoking, diabetes, or nutritional deficiencies.

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.
• Possible instability or abnormal movement of the leg.
• Visible deformity, though minimal or none in nondisplaced fractures.

Diagnosis

Physical examination to assess pain, alignment, and function. Imaging tests such as X-rays to visualize the fracture and confirm nonunion. MRI or CT scans may be used to evaluate bone healing, blood supply, or soft tissue involvement. Additional tests, like bone scans, can help assess metabolic activity at the fracture site.

Treatment Options

• Surgical intervention, such as internal fixation with plates or nails, to stabilize the fracture.
• Bone grafting to promote healing in cases of nonunion.
• External fixation devices for complex or infected fractures.
• Immobilization with a cast or brace to support healing.
• Physical therapy to restore strength and mobility after treatment.

Prognosis and Follow-Up

Prognosis depends on the severity of the nonunion, overall health, and response to treatment. Most patients achieve successful healing with appropriate intervention, but recovery may take several months. Regular follow-up with imaging is necessary to monitor progress. Physical therapy is often required to regain function and prevent complications like muscle atrophy or joint stiffness.

Complications

• Delayed or failed healing (nonunion or malunion).
• Infection, particularly if surgery is performed.
• Nerve or blood vessel damage near the fracture site.
• Chronic pain or reduced mobility.
• Long-term disability if healing is incomplete.

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Maintain a balanced diet rich in calcium and vitamin D to support bone health.
• Quit smoking and limit alcohol, as these can impair healing.
• Use protective equipment during sports or high-risk activities.
• Follow post-treatment guidelines, including weight-bearing restrictions and physical therapy.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, swelling, or inability to move the leg. Contact your healthcare provider if symptoms worsen, or if you notice signs of infection (e.g., fever, redness, or drainage). Follow up as scheduled to monitor healing and adjust treatment as needed.

Tips for Medical Coders

This code is used for a subsequent encounter for a closed fracture with nonunion of the right femur shaft. Document the encounter type (subsequent) and confirm the fracture is closed (no open wound) and nonunion (failure to heal). Ensure clinical documentation supports the nonunion diagnosis and subsequent care. Verify the right femur and oblique fracture pattern are clearly documented.
