S72.333N Displaced oblique fracture of shaft of unspecified femur, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with nonunion

Name of the Condition

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

Summary

A displaced oblique fracture of the shaft of the unspecified 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 are misaligned. This type of fracture involves the diaphysis (main structural part) of the femur and is classified as an open fracture (type IIIA, IIIB, or IIIC) during a subsequent encounter, indicating significant soft tissue damage and a nonunion (failure of the bone to heal properly).

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.

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 deformity or shortening of the leg (due to displacement).
• Possible numbness or tingling if nerve involvement occurs.

Diagnosis

Physical examination to assess pain, alignment, and function. Imaging tests such as X-rays to evaluate fracture healing and nonunion. Additional tests like CT scans or MRIs may be used to assess soft tissue damage or bone viability.

Treatment Options

Treatment may involve surgical intervention to realign the bone and promote healing, such as internal fixation with plates or screws. Bone grafting or other procedures may be necessary to address nonunion. Antibiotics or wound care may be required for open fractures.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, soft tissue damage, and response to treatment. Regular follow-up with imaging is typically needed to monitor healing. Physical therapy may be recommended to restore function and strength.

Complications

• Infection (especially with open fractures).
• Nerve or blood vessel damage.
• Chronic pain or stiffness.
• Malunion (improper healing) or nonunion.
• Long-term mobility issues.

Lifestyle & Prevention

• Avoid high-impact activities that increase fracture risk.
• Maintain bone health through diet and exercise.
• Use protective gear during sports or work.
• Address underlying conditions like osteoporosis.

When to Seek Professional Help

Seek immediate medical attention for severe pain, visible deformity, or inability to bear weight. Contact a healthcare provider if symptoms worsen or new complications arise.

Tips for Medical Coders

Document the fracture type (IIIA, IIIB, or IIIC), nonunion status, and subsequent encounter details. Ensure clinical notes specify the fracture's characteristics and treatment to support accurate coding.
