Understanding the Risks and Complications of Internal Fixation

Internal fixation is a surgical procedure commonly used to treat fractures and other bone injuries. It involves the use of metal implants, such as screws, plates, or rods, to stabilize the fractured bone and promote healing. While internal fixation is generally considered safe and effective, it is not without risks and potential complications. Understanding these risks is crucial for both patients and healthcare professionals involved in the decision-making process. This article aims to provide a comprehensive overview of the risks and complications associated with internal fixation, based on current research and medical literature.

Before undergoing any surgical procedure, including internal fixation, obtaining informed consent from the patient is essential. Informed consent involves providing the patient with detailed information about the procedure, its risks, benefits, and alternatives, allowing them to make an informed decision about their treatment. In the case of internal fixation, patients should be aware of the potential risks and complications associated with the procedure, as well as the expected outcomes and recovery process.

Healthcare professionals have a responsibility to ensure that patients fully understand the risks and benefits of internal fixation. This includes explaining the potential complications that may arise during or after the procedure, as well as the steps taken to minimize these risks. By obtaining informed consent, patients can actively participate in their treatment decisions and make choices that align with their preferences and values.

Common Risks and Complications

While internal fixation is generally considered safe, there are several risks and complications that patients should be aware of. These can vary depending on factors such as the type and location of the fracture, the patient’s overall health, and the surgical technique used. Some of the common risks and complications associated with internal fixation include:

  • Infection: One of the most significant risks of any surgical procedure is the potential for infection. In the case of internal fixation, the presence of metal implants can increase the risk of infection. Infections can occur at the surgical site or spread to the bone, leading to more severe complications.
  • Nonunion: Internal fixation aims to promote bone healing and union. However, in some cases, the fractured bone may fail to heal properly, resulting in a condition known as nonunion. Nonunion can occur due to various factors, such as poor blood supply, inadequate immobilization, or infection.
  • Malunion: Malunion refers to the improper healing of a fractured bone, leading to deformity or functional impairment. This can occur if the fracture is not adequately aligned or stabilized during the internal fixation procedure.
  • Hardware Failure: The metal implants used in internal fixation are designed to provide stability to the fractured bone. However, in some cases, these implants may fail due to factors such as loosening, breakage, or migration. Hardware failure can result in pain, loss of function, and the need for revision surgery.
  • Nerve and Blood Vessel Damage: During the internal fixation procedure, there is a risk of damaging nearby nerves and blood vessels. This can lead to complications such as numbness, weakness, or impaired blood supply to the affected area.

Preventing and Managing Complications

While complications can occur, healthcare professionals take several measures to minimize the risks associated with internal fixation. These include:

  • Thorough Preoperative Evaluation: Before performing internal fixation, healthcare professionals conduct a comprehensive evaluation of the patient’s overall health and the specific fracture. This helps identify any preexisting conditions or factors that may increase the risk of complications.
  • Proper Surgical Technique: The choice of surgical technique and the skill of the surgeon play a crucial role in minimizing complications. Surgeons must have the necessary expertise and experience to perform internal fixation effectively.
  • Strict Sterile Techniques: Infection prevention is a top priority during any surgical procedure. Healthcare professionals follow strict sterile techniques, including proper hand hygiene, the use of sterile instruments, and the administration of antibiotics when necessary.
  • Postoperative Care and Monitoring: After internal fixation, patients require close monitoring to ensure proper healing and identify any potential complications. This may involve regular follow-up appointments, imaging studies, and physical therapy.
  • Early Intervention: If complications do arise, early intervention is crucial. Prompt recognition and appropriate management can help prevent further damage and improve outcomes.

Factors Affecting Complication Rates

The risk of complications associated with internal fixation can vary depending on several factors. These include:

  • Patient Factors: The patient’s age, overall health, and lifestyle habits can influence the risk of complications. For example, older adults may have a higher risk of complications due to factors such as reduced bone density and slower healing.
  • Fracture Characteristics: The type, location, and severity of the fracture can impact the risk of complications. Complex fractures or those involving joints may be more challenging to treat and have a higher risk of complications.
  • Surgical Technique: The choice of surgical technique and the skill of the surgeon can significantly affect complication rates. Surgeons with more experience and expertise in internal fixation may have lower complication rates.
  • Implant Selection: The type and quality of the implants used in internal fixation can influence the risk of complications. High-quality implants designed for specific fracture types may have better outcomes and lower complication rates.


Internal fixation is a commonly used surgical procedure for the treatment of fractures and bone injuries. While it is generally considered safe and effective, there are risks and potential complications associated with the procedure. Patients and healthcare professionals must have a thorough understanding of these risks to make informed treatment decisions and provide appropriate care. By recognizing the common risks and complications, implementing preventive measures, and closely monitoring patients, healthcare professionals can minimize the occurrence and impact of complications associated with internal fixation.
