S72.345B Nondisplaced spiral fracture of shaft of left femur, initial encounter for open fracture type I or II

Name of the Condition

• Nondisplaced spiral fracture of shaft of left femur, initial encounter for open fracture type I or II (ICD-10 Code: S72.345B)

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 (nondisplaced). The fracture is associated with an open wound (open fracture type I or II) and is documented as the initial encounter for this injury. The spiral pattern results from rotational forces applied along the bone's axis, creating a helical or corkscrew-shaped break.

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. The open nature of the fracture (type I or II) indicates a break in the skin with minimal to moderate soft tissue damage.

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.
• Open fractures may be more likely in scenarios with direct impact to the thigh.

Symptoms

• Intense, localized pain in the left thigh.
• Swelling, bruising, or tenderness at the fracture site.
• Inability to bear weight or move the affected leg.
• Visible open wound (type I or II) at the fracture site.
• 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 open wound characteristics. Documentation of the open fracture type (I or II) and initial encounter status is critical for coding accuracy.

Treatment Options

Treatment focuses on stabilizing the fracture and managing the open wound. Options may include immobilization with a cast or brace, surgical fixation (e.g., intramedullary nailing), or external fixation. Open fractures require wound care, irrigation, and debridement to reduce infection risk. Pain management and physical therapy are often part of the recovery process.

Prognosis and Follow-Up

Prognosis depends on fracture severity, soft tissue damage, and treatment adherence. Nondisplaced fractures generally heal well with proper immobilization, but open fractures carry a higher risk of infection. Follow-up appointments monitor healing, wound status, and functional recovery. Physical therapy may be recommended to restore mobility and strength.

Complications

• Infection (especially with open fractures).
• Delayed healing or nonunion.
• Nerve or vascular damage.
• Malalignment if displacement occurs.
• Chronic pain or stiffness.

Lifestyle & Prevention

• Use protective gear during high-impact activities.
• Maintain bone health through diet and exercise.
• Avoid falls by modifying home environments (e.g., removing tripping hazards).
• Seek prompt medical care for trauma to the thigh.

When to Seek Professional Help

• Severe pain or inability to move the leg.
• Visible deformity or open wound.
• Numbness, tingling, or coldness in the leg.
• Signs of infection (e.g., redness, pus, fever).

Tips for Medical Coders

Document the fracture as nondisplaced, spiral, and involving the left femur shaft. Specify the open fracture type (I or II) and initial encounter status. Ensure clinical documentation supports the open wound classification and absence of displacement. Code S72.345B is appropriate for this scenario; verify laterality (left) and fracture characteristics match the record.
