S72.345A Nondisplaced spiral fracture of shaft of left femur, initial encounter for closed fracture

Name of the Condition

• Nondisplaced Spiral Fracture of Shaft of Left Femur, Initial Encounter for Closed Fracture (ICD-10 Code: S72.345A)

Summary

This condition describes a spiral-patterned break in the shaft (long central portion) of the left femur (thigh bone) where the bone fragments remain in their normal alignment. The fracture results from rotational forces applied along the bone's axis, creating a helical or corkscrew-shaped break. The term "initial encounter" indicates this is the first episode of care for the fracture, and "closed fracture" means the skin over the fracture site remains intact.

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 left 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 complex fracture patterns.

Treatment Options

Treatment depends on the fracture's severity and patient factors. Nondisplaced fractures may be managed with immobilization (e.g., casting or bracing) and pain control. Surgical intervention, such as intramedullary nailing or plating, may be required for unstable or complex cases. Physical therapy is often recommended during recovery to restore mobility and strength.

Prognosis and Follow-Up

Most nondisplaced fractures heal well with appropriate treatment, though recovery time varies. Follow-up care includes monitoring for healing progress, assessing functional recovery, and adjusting treatment as needed. Long-term outcomes depend on fracture severity, patient age, and adherence to rehabilitation.

Complications

• Delayed healing or nonunion.
• Malunion (improper healing).
• Infection (rare, especially with surgical intervention).
• Nerve or vascular damage.
• Post-traumatic arthritis (in severe cases).

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 falls by modifying home environments (e.g., removing tripping hazards).
• Consult a healthcare provider before starting new physical activities.

When to Seek Professional Help

Seek immediate medical attention if you experience severe thigh pain, inability to move the leg, visible deformity, or signs of nerve damage (e.g., numbness, tingling). Follow up with a provider if pain worsens, swelling persists, or you notice changes in limb function during recovery.

Tips for Medical Coders

Document the fracture's location (left femur shaft), pattern (spiral), displacement status (nondisplaced), encounter type (initial), and fracture type (closed). Include details on imaging, treatment provided, and any complications. Ensure documentation supports the specificity of the code and aligns with clinical findings.
