The Intertan Technique is an advanced medical approach primarily used in orthopedic surgery for fracture management. It involves the use of specialized intramedullary nails, such as the TRIGEN INTERTAN Nail, designed to provide stability and alignment in complex fractures. This method is renowned for its versatility and effectiveness in treating various types of femoral fractures, offering improved patient outcomes through minimally invasive procedures.
What is Intertan?
Intertan refers to a specialized intramedullary nail system used in orthopedic surgery, primarily for the treatment of fractures in long bones, particularly the femur. The INTERTAN Nail, such as the TRIGEN INTERTAN Nail, is designed to provide internal fixation and stability in complex fractures, including nonunions, malunions, and severely comminuted fractures. Its unique design allows for precise alignment and secure fixation, promoting proper healing and minimizing complications.
The INTERTAN system is characterized by its trapezoidal shape, which ensures a press-fit in the metaphyseal region. This design feature positions more material on the lateral side of the nail, where tensile forces are highest, enhancing durability and resistance to bending and stretching. The nail is typically inserted into the medullary canal of the bone, providing internal support and alignment without the need for external fixation devices.
Key indications for the INTERTAN Nail include simple long bone fractures, spiral fractures, long oblique fractures, and segmental fractures. It is also used in cases where traditional fracture management techniques may fail to achieve adequate stability. The system’s versatility and effectiveness have made it a preferred choice for orthopedic surgeons in treating a wide range of femoral fractures, from basi-cervical and intertrochanteric fractures to subtrochanteric fractures.
Historical Background and Development
The Intertan Technique has its roots in the evolution of intramedullary nailing, a surgical method that has been refined over decades to address complex bone fractures. The development of the Intertan system is closely tied to advancements in orthopedic surgery, particularly in the treatment of femoral fractures. Early intramedullary nails were relatively simple in design, but they laid the groundwork for more sophisticated systems like the Intertan Nail.
The concept of using intramedullary devices to stabilize fractures dates back to the mid-20th century. However, it wasn’t until the late 20th and early 21st centuries that the Intertan Technique emerged as a specialized approach. The TRIGEN INTERTAN Nail, a key component of this technique, was developed to address the limitations of earlier nailing systems, particularly in managing complex and comminuted fractures.
Key milestones in the development of the Intertan Technique include the introduction of its unique trapezoidal shape, which provides a press-fit in the metaphyseal region. This design innovation allowed for better stability and resistance to tensile forces, making it particularly effective for fractures in the femur. Over time, the system has undergone further refinements, including improvements in material properties and surgical instrumentation, to enhance its performance and versatility.
The historical development of the Intertan Technique reflects the broader advancements in orthopedic surgery, driven by the need for more effective and minimally invasive solutions for fracture management. Today, the Intertan Nail is recognized as a leading choice for treating a wide range of femoral fractures, from simple fractures to complex, multi-fragmentary injuries.

Overview of Surgical Applications
The Intertan Technique is widely applied in orthopedic surgery for the treatment of various fractures, particularly those involving long bones. Its primary use is in managing femoral fractures, including:
- Femoral neck fractures: Occurring at the base of the femoral head, these fractures benefit from the technique’s ability to provide stable fixation.
- Intertrochanteric fractures: Located between the greater and lesser trochanters, these fractures are effectively treated with the Intertan Technique due to its load-sharing capabilities.
- Subtrochanteric fractures: Occurring below the lesser trochanter, these fractures require strong stabilization, which the Intertan Technique delivers through its trapezoidal nail design.
Beyond femoral fractures, the Intertan Technique is also utilized in:
- Long bone fractures: The technique’s versatility extends to fractures in other long bones, offering consistent outcomes.
- Comminuted fractures: Fractures with multiple fragments are managed effectively with the Intertan Technique’s press-fit metaphyseal stabilization.
- Spiral fractures: These fractures, characterized by a twisting break, benefit from the technique’s ability to maintain alignment.
- Segmental fractures: Involving separate bone segments, the Intertan Technique ensures proper realignment and healing.
Additionally, the technique is employed in addressing complications such as nonunions and malunions, where fractures fail to heal or heal improperly. The Intertan Technique’s robust fixation and alignment capabilities make it an essential tool in modern orthopedic surgery, providing reliable outcomes across various fracture types and complexities.
