S72.062B Displaced articular fracture of head of left femur, initial encounter for open fracture type I or II

Name of the Condition

• Displaced articular fracture of head of left femur, initial encounter for open fracture type I or II

Summary

A displaced articular fracture of the head of the left femur involves a break in the femoral head (the rounded upper portion of the thigh bone that forms part of the hip joint) with the fracture fragments shifted out of their normal alignment. This injury disrupts the joint surface, which is critical for smooth movement. The fracture is classified as open (type I or II), meaning there is a wound communicating with the fracture site, and it is documented as an initial encounter, indicating the first episode of care for this specific injury. Prompt evaluation is necessary to assess the extent of displacement, wound severity, and guide appropriate management.

Causes

High-impact trauma, such as falls or motor vehicle accidents. Low-impact trauma in individuals with weakened bones (e.g., osteoporosis). Direct force to the hip region resulting in an open wound.

Risk Factors

• Advanced age, particularly in those over 65
• Osteoporosis or other bone density disorders
• Female gender, due to higher osteoporosis prevalence
• History of prior fractures or bone diseases
• Participation in high-risk activities (e.g., contact sports)
• Conditions that impair wound healing or increase fracture risk

Symptoms

• Sudden, severe hip or groin pain
• Inability to bear weight on the affected leg
• Swelling, bruising, or tenderness around the hip
• Leg shortening or external rotation of the affected limb
• Limited range of motion in the hip joint
• Visible wound or open fracture site (type I or II)

Diagnosis

Physical examination to assess pain, mobility, limb alignment, and wound characteristics. Imaging studies, including X-rays or CT scans, to visualize the fracture, displacement, and joint involvement. Evaluation of the open wound to determine its type and severity.

Treatment Options

• Surgical intervention to realign and stabilize the fracture, often with internal fixation or arthroplasty.
• Wound management for the open fracture, including cleaning and closure.
• Pain management and antibiotics to prevent infection.
• Rehabilitation, including physical therapy to restore mobility and strength.

Prognosis and Follow-Up

Prognosis depends on the extent of displacement, wound severity, and underlying bone health. Complications such as infection or arthritis may affect recovery. Follow-up care includes monitoring for healing, wound care, and rehabilitation progress. Long-term management may involve addressing joint function or complications.

Complications

• Infection at the open fracture site
• Nonunion or malunion of the fracture
• Post-traumatic arthritis of the hip joint
• Nerve or vascular injury
• Chronic pain or limited mobility

Lifestyle & Prevention

• Maintain bone health through adequate calcium and vitamin D intake.
• Engage in weight-bearing exercise to strengthen bones.
• Use protective gear during high-risk activities.
• Address fall risks, especially in older adults, through home modifications and balance training.

When to Seek Professional Help

Seek immediate medical attention for severe hip pain, inability to bear weight, visible wounds, or signs of infection (e.g., redness, pus, fever). Prompt care is critical to prevent complications and optimize outcomes.

Tips for Medical Coders

Document the fracture as displaced, involving the articular surface of the left femur head, with an open wound classified as type I or II. Specify the initial encounter and ensure the open fracture type is clearly recorded. Include details on the fracture mechanism, wound characteristics, and any associated injuries to support accurate coding.
