S72.335C Nondisplaced oblique fracture of shaft of left femur, initial encounter for open fracture type IIIA, IIIB, or IIIC

Name of the Condition

• Nondisplaced Oblique Fracture of Shaft of Left Femur, Initial Encounter for Open Fracture Type IIIA, IIIB, or IIIC

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 IIIA, IIIB, or IIIC) with significant soft tissue damage, contamination, or vascular injury, requiring immediate medical attention.

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, particularly when associated with open wounds or tissue disruption.

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.
• Open wounds or soft tissue injury at the fracture site.

Symptoms

• Sharp, localized pain in the thigh.
• Swelling, bruising, or tenderness around the fracture site.
• Inability to bear weight on the affected leg.
• Visible open wound or soft tissue damage (indicating an open fracture).
• Possible numbness or tingling if nerve involvement occurs.
• Signs of infection or vascular compromise (e.g., bleeding, discoloration).

Diagnosis

Physical examination to assess pain, alignment, and function, with careful evaluation of open wounds or soft tissue injury. Imaging tests such as X-rays to visualize the fracture and assess displacement. CT scans or MRI may be used to evaluate soft tissue damage, vascular involvement, or contamination in open fractures.

Treatment Options

Stabilization of the fracture, often with external fixation or surgical intervention, to address both the bone and soft tissue injury. Wound debridement and irrigation to clean open fractures, followed by antibiotics to prevent infection. Pain management and rehabilitation to restore function.

Prognosis and Follow-Up

Prognosis depends on the severity of soft tissue damage, infection risk, and adherence to treatment. Regular follow-up with imaging to monitor healing and assess for complications. Physical therapy may be required to regain mobility and strength.

Complications

• Infection at the fracture site or open wound.
• Delayed healing or nonunion.
• Vascular or nerve damage.
• Chronic pain or functional impairment.
• Post-traumatic arthritis.

Lifestyle & Prevention

Avoid high-risk activities or use protective gear during sports. Maintain bone health through diet and exercise. Seek prompt treatment for injuries to reduce complication risk.

When to Seek Professional Help

Seek immediate medical attention for severe pain, visible open wounds, or signs of infection (e.g., fever, increased swelling). Contact a healthcare provider if symptoms worsen or do not improve with treatment.

Tips for Medical Coders

Document the fracture type (oblique, nondisplaced), location (left femur shaft), and encounter type (initial for open fracture). Specify the open fracture classification (IIIA, IIIB, or IIIC) and any associated soft tissue or vascular injury. Ensure documentation supports the code assignment and reflects the clinical severity.
