S72.042 Displaced fracture of base of neck of left femur

Name of the Condition

• Displaced fracture of base of neck of left femur (S72.042)

Summary

This condition involves a break in the upper portion of the left femur (thigh bone) at the base of the femoral neck, near the hip joint. The term "displaced" indicates that the bone fragments have shifted out of their normal anatomical position. This type of fracture typically affects the structural integrity of the hip joint and may require prompt medical evaluation to determine the extent of injury and guide treatment.

Causes

High-impact trauma, such as falls or motor vehicle accidents, is a common cause. In older adults, particularly those with weakened bone density (e.g., osteoporosis), fractures may occur from minor trauma or low-impact events. Direct force to the hip or thigh region can also result in this injury.

Risk Factors

• Advanced age, especially in individuals over 65
• Osteoporosis or other bone-weakening conditions
• Female gender, due to higher osteoporosis prevalence
• History of prior fractures or bone diseases
• Participation in high-risk activities (e.g., contact sports)

Symptoms

• Severe pain in the hip or groin area
• Swelling, bruising, or tenderness around the hip
• Inability to bear weight on the affected leg
• Visible deformity or shortening of the leg
• Limited range of motion in the hip joint

Diagnosis

Physical examination to assess pain, mobility, and limb alignment. Imaging studies, including X-rays or CT scans, to visualize the fracture and determine displacement.

Treatment Options

• Non-surgical: Temporary immobilization with a brace or cast, and physical therapy.
• Surgical: Internal fixation (e.g., screws, plates) or hip replacement, depending on fracture severity and patient factors.

Prognosis and Follow-Up

Recovery depends on fracture type, treatment, and patient health. Most patients regain mobility with proper care, but complications like arthritis or reduced function may occur. Follow-up includes monitoring healing, physical therapy, and long-term joint health assessment.

Complications

• Nonunion or malunion of the fracture
• Avascular necrosis (bone tissue death due to reduced blood supply)
• Post-traumatic arthritis of the hip
• Infection (if surgery is performed)
• Chronic pain or reduced mobility

Lifestyle & Prevention

• Maintain bone health with calcium and vitamin D intake.
• Engage in weight-bearing exercise to strengthen bones.
• Use fall-prevention strategies (e.g., home modifications, assistive devices) for older adults.
• Avoid high-risk activities that increase fracture likelihood.

When to Seek Professional Help

Seek immediate care for severe hip pain, inability to bear weight, or visible deformity after trauma. Prompt evaluation is critical to prevent complications and optimize treatment outcomes.

Tips for Medical Coders

Document the fracture location (left femur), displacement status, and any associated injuries. Ensure clinical notes specify the affected side and fracture details to support accurate coding. Include details on treatment approach (surgical vs. non-surgical) and follow-up care for comprehensive coding.
