S72.335B Nondisplaced oblique fracture of shaft of left femur, initial encounter for open fracture type I or II

Name of the Condition

• Nondisplaced Oblique Fracture of Shaft of Left Femur, Initial Encounter for Open Fracture Type I or II

Summary

A nondisplaced oblique fracture of the shaft of the left 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 type of fracture involves the diaphysis (main structural part) of the femur and is classified as an open fracture type I or II, indicating a break in the skin with minimal contamination or soft tissue damage. The fracture is considered stable due to the lack of displacement.

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. The open nature of the fracture suggests the bone has pierced the skin, typically due to the force of the injury.

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.

Symptoms

• Sharp, localized pain in the thigh.
• Swelling, bruising, or tenderness around the fracture site.
• Inability to bear weight on the affected leg.
• Visible wound or break in the skin (due to open fracture).
• Possible numbness or tingling if nerve involvement occurs.

Diagnosis

Physical examination to assess pain, alignment, and function. Imaging tests such as X-rays to visualize the fracture and confirm nondisplacement. CT scans may be used for detailed assessment of the fracture pattern and surrounding soft tissue. Evaluation of the open wound to determine fracture type (I or II) and assess for contamination.

Treatment Options

Stabilization with immobilization (e.g., casting or bracing) to allow healing. Surgical intervention may be required if the fracture is unstable or if soft tissue damage is significant. Antibiotics and wound care to prevent infection for open fractures. Pain management and physical therapy to restore mobility and strength.

Prognosis and Follow-Up

Prognosis is generally favorable with proper treatment, as nondisplaced fractures tend to heal well. Follow-up appointments to monitor healing through imaging and assess functional recovery. Gradual return to weight-bearing activities as tolerated, guided by clinical progress.

Complications

• Infection (risk increased with open fractures).
• Delayed healing or nonunion.
• Nerve or vascular damage.
• Post-traumatic arthritis.
• Muscle atrophy or stiffness.

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Maintain bone health through diet and exercise.
• Avoid falls by modifying home environments (e.g., removing tripping hazards).
• Seek prompt treatment for injuries to prevent complications.

When to Seek Professional Help

• Severe pain or swelling that worsens.
• Visible deformity or inability to move the leg.
• Signs of infection (e.g., redness, pus, fever).
• Numbness, tingling, or loss of circulation in the leg.

Tips for Medical Coders

Document the fracture type (oblique), location (shaft of left femur), displacement status (nondisplaced), and open fracture classification (type I or II) to ensure accurate coding. Include details of the initial encounter and any associated soft tissue injury or wound characteristics. Verify that the code aligns with the clinical documentation to reflect the specific nature of the fracture.
