Pelvis Fracture: External Fixation

Pelvis fracture external fixation refers to a surgical procedure used to stabilize fractures of the pelvic bones using an external frame or device. This method is typically employed when internal fixation is either not immediately possible or in cases of severe trauma where rapid stabilization is necessary to control bleeding and maintain alignment.

Purpose of External Fixation for Pelvic Fractures

The primary goals of using external fixation for pelvic fractures include:

1. Immediate Stabilization:

• Providing quick stabilization of the pelvic bones to prevent further injury and control bleeding.
• Reducing movement at the fracture site to promote proper alignment and healing.
• Serving as a temporary measure until the patient is stable enough for definitive internal fixation or other treatments.
• Managing complex fractures, especially in polytrauma patients, where internal fixation may be contraindicated initially.

3. Managing Severe Trauma:

Procedure Overview

1. Preoperative Evaluation:

• Comprehensive evaluation, including imaging studies (X-rays, CT scans), to assess the extent of the pelvic fracture and associated injuries.
• The procedure is usually performed under general anesthesia or regional anesthesia.
• Insertion of Pins or Screws:
  • Metal pins or screws are inserted into the pelvic bones through small incisions in the skin.
  • Application of External Frame:
    • These pins or screws are connected to an external frame or bar system outside the body.
  • Alignment Adjustment:
    • The frame is adjusted to align the fractured pelvic bones properly.
  • Fixation:
    • The external fixator is securely tightened to hold the bones in the correct position.
  • Monitoring for any complications such as infection at the pin sites.
  • Pain management and stabilization of the patient.
  • Gradual mobilization as permitted by the treating physician.

Advantages of External Fixation

1. Rapid Stabilization:

• Provides quick and effective stabilization of the pelvic fracture, which is crucial in emergency settings.
• Helps control bleeding from pelvic fractures, which can be life-threatening.
• Less invasive compared to internal fixation, reducing the risk of complications in unstable patients.
• Allows time for the patient to stabilize before a more definitive surgical intervention.
• The external fixator can be adjusted postoperatively to maintain or improve alignment.

Disadvantages of External Fixation

1. Risk of Infection:

• The insertion sites of the pins or screws can become infected.
• The external frame can be uncomfortable and restrict the patient’s mobility.
• External fixation is generally a temporary solution, often necessitating further surgery for internal fixation.
• Risks of skin irritation, pressure sores, and other soft tissue complications around the pin sites.
• Requires careful monitoring and maintenance to prevent complications and ensure proper function.

Considerations

• Patient’s Overall Health:
  • The patient’s overall condition and stability play a crucial role in the decision to use external fixation.
• Severity and Complexity of the Fracture:
  • The extent and type of pelvic fracture influence the choice of fixation method.
• Polytrauma Management:
  • External fixation is often part of the initial management of patients with multiple injuries, allowing for stabilization while other life-threatening conditions are addressed.
