S72.344B Nondisplaced spiral fracture of shaft of right femur, initial encounter for open fracture type I or II

Name of the Condition

• Nondisplaced spiral fracture of shaft of right femur, initial encounter for open fracture type I or II (ICD-10 Code: S72.344B)

Summary

This condition describes a spiral-patterned break in the shaft (long central portion) of the right femur (thigh bone) where the bone fragments remain in their normal alignment (nondisplaced). The fracture is associated with an open wound (type I or II) and is documented as the initial encounter for this injury. The spiral pattern results from rotational forces applied to the bone, 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 indicates a break in the skin, allowing communication between the fracture site and the external environment.

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 situations with direct impact or penetrating injuries.

Symptoms

• Intense, localized pain in the right thigh.
• Swelling, bruising, or tenderness around the fracture site.
• Inability to bear weight or move the affected leg.
• Possible visible deformity (if displaced, though nondisplaced fractures may show minimal deformity).
• Open wound at the fracture site (type I or II).
• 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 plates), and wound care for the open fracture. Antibiotics may be administered to prevent infection, and pain management is typically provided. The approach depends on the fracture severity and wound type.

Prognosis and Follow-Up

Prognosis is generally favorable for nondisplaced fractures, especially with proper treatment. Healing time varies but often ranges from 8 to 12 weeks. Follow-up appointments monitor healing progress through imaging and physical exams. Rehabilitation may be recommended to restore strength and mobility. Open fractures require close monitoring for infection or complications.

Complications

• Infection at the open wound site.
• Delayed healing or nonunion.
• Nerve or vascular damage.
• Malalignment if displacement occurs post-treatment.
• Chronic pain or stiffness.
• Potential for deep vein thrombosis (DVT) due to immobility.

Lifestyle & Prevention

• Avoid high-impact or rotational activities that increase fracture risk.
• Maintain bone health through diet (calcium, vitamin D) and exercise.
• Use protective gear during sports or high-risk activities.
• Address osteoporosis or bone weaknesses with medical management.
• Promptly treat open wounds to reduce infection risk.

When to Seek Professional Help

Seek immediate medical attention for severe pain, inability to move the leg, visible deformity, or open wounds. Contact a healthcare provider if swelling, bruising, or pain worsens, or if signs of infection (e.g., redness, pus, fever) develop. Follow up as recommended for fracture healing and wound care.

Tips for Medical Coders

Document the fracture as nondisplaced, spiral, and involving the right femur shaft. Specify the open fracture type (I or II) and note the initial encounter status. Ensure clinical documentation supports the open wound classification and absence of displacement. Verify that all elements of the code (anatomical site, fracture type, laterality, and encounter type) are clearly recorded for accurate coding.
