S72.113B Displaced fracture of greater trochanter of unspecified femur, initial encounter for open fracture type I or II

Name of the Condition

• Displaced fracture of greater trochanter of unspecified femur, initial encounter for open fracture type I or II

Summary

A displaced fracture of the greater trochanter of the femur is a break in the bony prominence on the upper part of the thigh bone (femur) near the hip joint, where the bone fragment has moved out of its normal position. This type of fracture is classified as an open fracture (type I or II) during the initial encounter, meaning the overlying skin is compromised but the wound is limited. It typically results from trauma or weakened bone structure and may involve significant displacement of the bone fragment.

Causes

Displaced fractures of the greater trochanter commonly result from direct trauma, such as falls or high-impact injuries. They can also occur in individuals with weakened bones due to conditions like osteoporosis, where even minor stress may cause a fracture with displacement. Open fractures (type I or II) may result from the same mechanisms, with the added factor of skin penetration by the fractured bone or associated trauma.

Risk Factors

• Advanced age, particularly in postmenopausal women with osteoporosis.
• Conditions that weaken bones, such as osteoporosis, cancer, or metabolic disorders.
• History of previous fractures or falls.
• Sedentary lifestyle or limited mobility.
• High-impact activities or accidents that increase fracture risk.

Symptoms

• Severe hip or groin pain, often worsened by movement.
• Inability to bear weight on the affected leg.
• Swelling, bruising, or deformity around the hip.
• Leg shortening or external rotation.
• Visible wound or skin breach (for open fractures).

Diagnosis

Physical examination to assess pain, range of motion, and deformity. Imaging studies, including X-rays or CT scans, to confirm the fracture and evaluate displacement. Assessment of the wound for open fracture classification (type I or II) during the initial encounter.

Treatment Options

• Surgical intervention, such as internal fixation with screws or plates, to stabilize the fracture.
• Wound care for open fractures to prevent infection.
• Pain management and immobilization with a brace or cast.
• Physical therapy to restore mobility and strength after healing.

Prognosis and Follow-Up

Prognosis depends on the severity of displacement, bone quality, and treatment success. Most patients recover with proper management, though mobility may be temporarily limited. Follow-up imaging and clinical evaluations are typically scheduled to monitor healing and adjust treatment as needed.

Complications

• Infection (for open fractures).
• Nonunion or malunion of the fracture.
• Chronic pain or hip stiffness.
• Nerve or vascular damage.
• Post-traumatic arthritis.

Lifestyle & Prevention

• Maintain bone health through adequate calcium and vitamin D intake.
• Engage in weight-bearing exercises to strengthen bones.
• Use fall prevention strategies, such as home modifications and assistive devices.
• Avoid high-impact activities that increase fracture risk.

When to Seek Professional Help

Seek immediate medical attention for severe hip pain, inability to bear weight, or visible wounds after trauma. Prompt evaluation is critical for open fractures to reduce infection risk and ensure proper treatment.

Tips for Medical Coders

Document the fracture as displaced and specify the open fracture type (I or II) during the initial encounter. Include details on the affected femur (unspecified) and confirm the encounter is initial. Ensure clinical documentation supports the open fracture classification to justify the code.
