The INTERTAN Nail is a state-of-the-art intramedullary fixation system distinguished by its unique integrated dual-screw design. It is specifically engineered to treat a wide range of proximal femoral fractures, including complex and unstable patterns. The dual-screw construct provides enhanced rotational and angular stability, working in tandem to resist the powerful forces that can lead to implant failure. By combining a less invasive approach with superior biomechanical performance, the INTERTAN Nail facilitates robust internal support, allowing for early weight-bearing and a more reliable recovery.
INTERTAN Nail
TOOLMED
Product Description
The system features two integrated screws (a lag screw and an antirotation screw) that work together to provide enhanced rotational and angular stability within the femoral head and neck.
The nail is contoured to match the natural shape of the femur, which allows for a close fit in the medullary canal and facilitates a smooth surgical procedure.
The INTERTAN Nail allows for controlled micromotion at the fracture site post-operatively, which can promote secondary bone healing and encourage callus formation.
Designed for a minimally invasive surgical technique, the system can be implanted through a small incision, reducing soft tissue trauma and patient recovery time.
The implant is made from a high-quality titanium alloy, offering superior strength, biocompatibility, and fatigue resistance for long-term support and stability.
The INTERTAN Nail is indicated for the treatment of unstable intertrochanteric, subtrochanteric, and basilar neck fractures.
It is particularly suitable for complex and unstable fracture patterns where enhanced rotational control and compression are required to achieve a successful fixation.
The implant is used in both high-energy fractures in younger patients and osteoporotic fractures in elderly patients, where its dual-screw design provides enhanced stability.

The INTERTAN Nail is a dual-screw intramedullary nail system that represents a significant advancement in the treatment of proximal femoral fractures. Unlike traditional nails that use a single blade or screw, the INTERTAN system utilizes two integrated screws that are inserted into the femoral head. This innovative design is engineered to provide superior rotational and angular stability by creating a more robust fixation construct, thereby reducing the risk of implant failure in unstable fracture patterns.
The INTERTAN Nail is primarily indicated for a wide range of proximal femoral fractures. These include unstable intertrochanteric fractures, where the fracture line extends into the subtrochanteric region, and basilar neck fractures.
The dual-screw design provides particular advantages in complex and comminuted fractures where a high degree of rotational stability is required to achieve a successful fixation.
It is also a popular choice for treating fractures in osteoporotic bone due to its ability to provide strong fixation and resist the forces that lead to implant cut-out.
The INTERTAN Nail offers several key advantages over other intramedullary nails. Its dual-screw design provides enhanced rotational control and stability, which is crucial for preventing fracture fragment rotation and ensuring proper healing.
The system's biomechanics are designed to provide robust compression at the fracture site, which promotes early bone healing. This, combined with the implant's inherent stability, often allows for immediate or early weight-bearing, facilitating a faster recovery.
The minimally invasive surgical technique reduces patient trauma and allows for a quicker return to daily activities. The implant's advanced design also helps reduce the risk of implant failure and the need for revision surgery.
The biomechanics of the INTERTAN Nail are centered on the synergistic action of its two integrated screws. The screws work in tandem to provide a strong foundation within the femoral head, effectively resisting rotational forces and providing superior torsional stability. This integrated design also allows for controlled fracture compression, which stimulates callus formation and promotes bone healing. The nail’s position within the medullary canal provides robust column support, ensuring load-sharing and preventing varus collapse.
The implantation of the INTERTAN Nail is performed using a minimally invasive surgical technique. A small incision is made at the tip of the greater trochanter, and a guide wire is inserted into the femoral canal. The nail is then carefully inserted over the guide wire. The dual screws are then placed through the nail and into the femoral head, providing a strong, integrated fixation.
Final placement is confirmed with fluoroscopic guidance, and distal locking screws are then inserted to secure the nail and complete the fixation.
The entire procedure is designed to be streamlined and efficient, ensuring accurate and stable implant placement with minimal disruption to the surrounding soft tissues.
Following a successful INTERTAN Nail fixation, the patient can often begin early, partial weight-bearing as tolerated. Physical therapy is a crucial component of recovery, focusing on restoring joint range of motion and muscle strength to help the patient return to their daily activities more quickly.
Patients are instructed on proper care of the surgical site and are provided with a structured rehabilitation program.
Regular clinical and radiographic follow-up appointments are essential to monitor fracture healing and ensure the implant remains stable throughout the recovery process.
The INTERTAN Nail is a highly effective and advanced solution for treating a wide range of proximal femoral fractures. Its innovative dual-screw design provides superior rotational stability and compression, which are critical for achieving a successful fixation, especially in unstable and osteoporotic fractures. By facilitating a minimally invasive approach and promoting early patient mobility, the INTERTAN Nail leads to excellent clinical outcomes and a faster return to a high quality of life.
The primary difference is the INTERTAN's integrated dual-screw design, which provides enhanced rotational and compressive stability compared to the single-screw or blade design of most standard femoral nails.
The dual-screw design provides superior rotational control, which is vital for preventing fracture rotation and promoting healing. It also offers better compression and reduces the risk of the implant "cutting out" from the bone, especially in osteoporotic patients.
It is particularly well-suited for unstable proximal femoral fractures, including intertrochanteric fractures, subtrochanteric fractures, and basilar neck fractures, where its dual-screw system provides superior stability.
Yes, the implant is typically made from high-quality titanium alloy, which is a standard material in orthopedic implants due to its biocompatibility and strength.
Yes, the inherent stability provided by the dual-screw design and intramedullary position often allows for early, or even immediate, weight-bearing as tolerated by the patient and as prescribed by the surgeon.
