S72.346 Nondisplaced spiral fracture of shaft of unspecified femur

Name of the Condition

• Nondisplaced Spiral Fracture of Shaft of Unspecified Femur (ICD-10 Code: S72.346)

Summary

A nondisplaced spiral fracture of the femur shaft is a bone break in the long central portion of the thigh bone, where the fracture line follows a twisting pattern but the bone fragments remain aligned. This type of fracture results from rotational forces applied to the bone, often without significant displacement or angulation of the fragments.

Causes

Such fractures typically result from high-impact trauma, such as motor vehicle accidents, falls from significant heights, or direct rotational forces to the thigh. Sports injuries, industrial accidents, or other events involving twisting or torsional stress can also cause this type of fracture.

Risk Factors

• Participation in high-impact or rotational activities (e.g., contact sports, skiing).
• Osteoporosis or weakened bone conditions.
• Advanced age, due to decreased bone density.
• Prior history of fractures or bone abnormalities.
• Trauma involving significant rotational force.

Symptoms

• Intense, localized pain in the thigh.
• Swelling, bruising, or tenderness around the fracture site.
• Inability to bear weight or move the affected leg.
• Possible visible deformity or shortening of the leg (if displaced).
• Numbness or tingling if nerve involvement occurs.

Diagnosis

Physical examination to assess pain, alignment, and function. Imaging tests such as X-rays to confirm the fracture type, displacement, and location. Additional scans (e.g., CT or MRI) may be used to evaluate soft tissue damage or associated injuries.

Treatment Options

• Immobilization with a cast or brace to stabilize the fracture.
• Pain management with medications or other interventions.
• Surgical intervention if displacement occurs or if the fracture is unstable.
• Physical therapy to restore strength and mobility after healing.

Prognosis and Follow-Up

Most nondisplaced spiral fractures heal well with proper immobilization and follow-up care. Recovery time depends on the patient's age, overall health, and adherence to treatment. Regular follow-up appointments are necessary to monitor healing and adjust treatment as needed.

Complications

• Delayed healing or nonunion of the fracture.
• Infection, particularly if surgical intervention is required.
• Nerve or vascular damage in severe cases.
• Long-term pain or functional limitations.

Lifestyle & Prevention

• Engage in weight-bearing exercises to maintain bone density.
• Use protective gear during high-risk activities.
• Ensure adequate calcium and vitamin D intake.
• Avoid activities that pose a high risk of falls or trauma.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, swelling, or inability to move the leg after an injury. Contact a healthcare provider if symptoms worsen or if you notice signs of infection, such as fever or increased redness.

Tips for Medical Coders

Document the fracture type (spiral), displacement status (nondisplaced), and bone involved (femur shaft, unspecified). Include details about the mechanism of injury, imaging results, and treatment provided to support accurate coding. Ensure the unspecified femur designation is appropriate when laterality is not documented.
