S72.343 Displaced spiral fracture of shaft of unspecified femur

Name of the Condition

• Displaced Spiral Fracture of Shaft of Unspecified Femur (ICD-10 Code: S72.343)

Summary

This condition describes a spiral-patterned break in the shaft (long central portion) of the femur (thigh bone), where the bone fragments are displaced from their normal alignment. The fracture results from rotational forces applied along the bone's axis, creating a helical or corkscrew-shaped break. The term "unspecified" indicates the side of the femur is not documented.

Causes

Often results from high-impact trauma, such as a fall, motor vehicle accident, or sports injury. The spiral pattern typically occurs when a rotational force is applied to the femur, causing the bone to twist and fracture along a helical path.

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 at the fracture site.
• Inability to bear weight or move the affected leg.
• Visible deformity or shortening of the leg (if displaced).
• Possible 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 fractures.

Treatment Options

Treatment depends on fracture severity and patient factors. Options include immobilization with a cast or brace, surgical fixation (e.g., intramedullary nailing, plates, screws), and pain management. Physical therapy may be recommended during recovery to restore mobility and strength.

Prognosis and Follow-Up

Prognosis varies based on fracture severity, treatment, and patient health. Most fractures heal with proper care, but recovery may take several months. Follow-up appointments monitor healing, alignment, and functional recovery. Complications like nonunion or malunion require additional management.

Complications

• Infection (especially with surgical intervention).
• Nerve or vascular damage.
• Nonunion (failure to heal) or malunion (improper healing).
• Post-traumatic arthritis.
• Chronic pain or limited mobility.

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Maintain bone health through diet (calcium, vitamin D) and exercise.
• Fall prevention strategies for older adults (e.g., home modifications, balance training).
• Avoid excessive rotational forces to the thigh.

When to Seek Professional Help

Seek immediate care for severe pain, inability to move the leg, visible deformity, or signs of nerve/vascular injury (e.g., numbness, coldness). Follow up with a healthcare provider if pain worsens, swelling persists, or mobility does not improve.

Tips for Medical Coders

Document the fracture as "unspecified" when the side of the femur is not clearly identified. Ensure clinical documentation supports displacement and spiral fracture pattern. Verify no laterality is specified before assigning S72.343.
