S72.336B Nondisplaced oblique fracture of shaft of unspecified femur, initial encounter for open fracture type I or II

Name of the Condition

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

Summary

A nondisplaced oblique fracture of the shaft of the 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 soft tissue damage. The fracture is described as "initial encounter," meaning this is the first episode of care for the injury.

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. Open fractures occur when the bone pierces the skin, typically due to severe trauma.

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 assess displacement. CT scans may be used for detailed assessment of the fracture pattern and soft tissue involvement. Evaluation of the open wound to determine fracture type (I or II) is critical.

Treatment Options

Stabilization of the fracture, often with immobilization (e.g., casting or bracing) or surgical fixation (e.g., intramedullary nailing) if needed. Wound care for the open fracture, including cleaning and dressing. Pain management and antibiotics to prevent infection. Physical therapy to restore mobility and strength as healing progresses.

Prognosis and Follow-Up

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

Complications

• Infection at the open wound site.
• Delayed healing or nonunion.
• Nerve or vascular damage.
• Chronic pain or stiffness.
• Malalignment if treatment is inadequate.

Lifestyle & Prevention

• Use protective gear during high-risk activities (e.g., helmets, padding).
• Maintain bone health through diet (calcium, vitamin D) and exercise.
• Fall prevention strategies for older adults (e.g., home modifications, balance training).
• Avoid excessive force or trauma to the thigh.

When to Seek Professional Help

Seek immediate medical attention for severe pain, visible bone protrusion, uncontrolled bleeding, or signs of infection (e.g., redness, pus). Follow up with a healthcare provider if pain worsens, swelling persists, or mobility does not improve.

Tips for Medical Coders

Document the fracture type (oblique), displacement status (nondisplaced), femur side (unspecified), and encounter type (initial). Specify the open fracture classification (type I or II) and any associated injuries. Ensure documentation supports the code assignment and reflects the clinical details of the injury.
