S72.334Q Nondisplaced oblique fracture of shaft of right femur, subsequent encounter for open fracture type I or II with malunion

Name of the Condition

• Nondisplaced Oblique Fracture of Shaft of Right Femur

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 type of fracture involves the diaphysis (main structural part) of the femur. The subsequent encounter for open fracture type I or II with malunion indicates a follow-up visit for a previously treated open fracture (with minimal soft tissue damage) that has healed with improper alignment.

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.
• Possible numbness or tingling if nerve involvement occurs (less common in nondisplaced fractures).

Diagnosis

Physical examination to assess pain, alignment, and function. Imaging tests such as X-rays to visualize the fracture and confirm malunion. CT or MRI scans may be used to evaluate soft tissue healing or assess the extent of malalignment.

Treatment Options

• Immobilization with a cast or brace to support healing.
• Physical therapy to restore strength and mobility.
• Surgical intervention (e.g., osteotomy) if malunion causes functional impairment or pain.
• Pain management with medications as needed.

Prognosis and Follow-Up

Most nondisplaced fractures heal well with proper immobilization and follow-up care. Malunion may require additional treatment if it affects mobility or causes discomfort. Regular follow-up appointments monitor healing progress and adjust treatment plans as necessary.

Complications

• Malunion (improper bone healing, as noted in the code).
• Nonunion (failure of the fracture to heal).
• Infection (if the original fracture was open).
• Nerve or vascular damage (rare but possible).
• Chronic pain or reduced mobility.

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Use protective gear during sports or work to reduce injury risk.
• Maintain bone health through a balanced diet rich in calcium and vitamin D.
• Engage in weight-bearing exercises to strengthen bones (as advised by a provider).

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, swelling, or inability to move the leg. Contact your provider if you notice increased pain, signs of infection (e.g., redness, fever), or if the fracture site does not improve with treatment.

Tips for Medical Coders

Document the encounter as a subsequent visit for an open fracture type I or II with malunion. Ensure clinical notes specify the fracture type, alignment status, and any treatment provided. The code S72.334Q requires clear documentation of the malunion and the open fracture classification to support accurate coding.
