The INTERTAN nail features a unique integrated interlocking lag screw system, comprising a main lag screw above and a compression screw below, effectively stabilizing the fracture site and minimizing the risk of implant failure.
The INTERTAN nail is characterized by a trapezoidal shape, providing a press-fit in the metaphyseal region. This design strategically positions more material on the lateral side of the nail, where tensile/stretching forces are typically greatest. The nail’s honeycomb structure enhances its stability and resistance to bending, further contributing to its overall strength and reliability. The INTERTAN nail’s versatility extends to its compatibility with both single and double guide pin techniques, offering surgeons flexibility in their surgical approach based on the specific fracture pattern and patient anatomy.
Indications
The TRIGEN INTERTAN Intertrochanteric Antegrade Nail is indicated for the surgical treatment of a wide range of unstable intertrochanteric fractures of the femur, specifically those classified as OTA 31-A2.1, 31-A2.2, and 31-A2.3. These fractures are characterized by significant displacement and instability, making them challenging to manage conservatively. The INTERTAN nail provides a stable and reliable fixation solution for these complex fracture patterns, promoting fracture healing and restoring functional mobility in patients.
The INTERTAN nail is particularly well-suited for patients with osteoporotic bone, a condition often associated with fragility fractures. Its unique design and robust fixation capabilities effectively address the challenges posed by osteoporotic bone, minimizing the risk of implant failure and complications. The INTERTAN nail is also indicated for patients who are not suitable for traditional surgical approaches, such as open reduction and internal fixation (ORIF) with a sliding hip screw, due to factors like limited bone stock or a high risk of complications.
Contraindications
While the TRIGEN INTERTAN Intertrochanteric Antegrade Nail is a valuable tool for treating unstable intertrochanteric fractures, certain conditions may preclude its use. These contraindications are crucial to consider for optimal patient safety and treatment outcomes.
One major contraindication is the presence of an open fracture. Open fractures, where the bone breaks through the skin, carry a high risk of infection. The INTERTAN nail is not designed for open fracture treatment due to the increased risk of infection associated with intramedullary nailing in such scenarios.
Severe comminution of the fracture fragments, where the bone is broken into multiple pieces, can also pose a challenge for the INTERTAN nail. The extensive comminution may make it difficult to achieve stable fracture reduction and secure the nail in place.
In addition, patients with severe osteoporosis, where the bone is exceptionally weak and brittle, may be unsuitable candidates for the INTERTAN nail. The nail’s insertion and fixation may be challenging in such fragile bone, potentially leading to implant failure or complications.
Surgical Technique
The surgical technique for the TRIGEN INTERTAN Intertrochanteric Antegrade Nail involves a series of steps, each meticulously executed to ensure proper fracture reduction and stable fixation.

Surgical Approach
The surgical approach for the TRIGEN INTERTAN Intertrochanteric Antegrade Nail procedure involves a meticulous and precise incision to expose the fracture site and allow for the insertion of the nail. The incision is typically made over the lateral aspect of the thigh, extending from just below the greater trochanter to the proximal shaft of the femur.
The incision is carefully dissected through the subcutaneous tissue and fascia, exposing the vastus lateralis muscle. The muscle is carefully retracted to visualize the proximal femur and the fracture site.
The surgical approach is designed to minimize tissue damage and optimize visualization of the fracture site. The surgeon carefully retracts the surrounding soft tissues to expose the fracture, ensuring adequate working space for the insertion of the nail and other implants.
Fracture Reduction
Fracture reduction is a critical step in the TRIGEN INTERTAN Intertrochanteric Antegrade Nail procedure, ensuring proper alignment and stability of the fractured bone fragments. The reduction process aims to restore the anatomical configuration of the femur, minimizing any displacement or angulation.
The surgeon uses a variety of instruments and techniques to achieve fracture reduction. These may include manual manipulation, traction, and the use of reduction forceps. Fluoroscopic imaging is employed throughout the procedure to guide the reduction process and ensure accurate alignment of the fracture fragments.
Once the fracture is adequately reduced, the surgeon verifies the reduction with fluoroscopy and proceeds to the next stage of the procedure, which involves the insertion of the TRIGEN INTERTAN nail.
Nail Insertion
Nail insertion is a crucial step in the TRIGEN INTERTAN Intertrochanteric Antegrade Nail procedure, involving the placement of the nail into the medullary canal of the femur. This process is designed to provide stability and support to the fractured bone, promoting healing and restoring function.
The nail is inserted through a carefully planned entry portal, typically located just proximal to the greater trochanter. A guide pin is used to establish the correct trajectory for the nail, ensuring that it is placed in the center of the medullary canal.
The surgeon then uses a specialized hammer or driver to advance the nail into the femur, following the guide pin’s path. The nail’s unique design incorporates features such as a trapezoidal shape and a press-fit in the metaphyseal region, maximizing stability and providing a secure fixation of the fractured bone fragments.
The insertion process is carefully monitored with fluoroscopy to ensure accurate placement and prevent any complications.
Proximal Locking
Proximal locking is a critical step in the TRIGEN INTERTAN Intertrochanteric Antegrade Nail procedure, involving the secure fixation of the nail to the proximal femur. This process ensures stability and prevents the nail from migrating, promoting optimal fracture healing and restoring the patient’s mobility.
The proximal locking mechanism typically utilizes a series of locking screws, strategically placed into pre-drilled holes in the proximal portion of the nail. The surgeon carefully selects the appropriate size and number of screws based on the patient’s bone quality and the fracture pattern.
The locking screws are inserted using specialized drills and drivers, ensuring accurate placement and a tight fit. This secure fixation helps to transfer load from the proximal femur to the nail, effectively stabilizing the fracture and promoting healing.
The locking process is carefully monitored with fluoroscopy to confirm the precise placement of the screws and ensure their secure engagement within the bone.
Distal Locking
Distal locking, a crucial step in the TRIGEN INTERTAN Intertrochanteric Antegrade Nail procedure, involves securing the nail to the distal femur. This process enhances stability, preventing the nail from sliding or migrating and promoting optimal fracture healing.
The distal locking technique typically involves the use of locking screws, strategically placed into pre-drilled holes in the distal portion of the nail. These screws are carefully chosen based on the patient’s bone quality and the fracture pattern. The surgeon uses specialized drills and drivers to insert the screws, ensuring accurate placement and a tight fit.
The locking screws effectively transfer load from the distal femur to the nail, further stabilizing the fracture and promoting healing. The precise placement of the screws is monitored with fluoroscopy to ensure their secure engagement within the bone.
The distal locking process is an integral part of the overall procedure, contributing significantly to the success of the TRIGEN INTERTAN Intertrochanteric Antegrade Nail technique. It ensures the stability and strength required for optimal fracture healing and restoration of the patient’s mobility.
Lag Screw Insertion
Lag screw insertion is a critical step in the TRIGEN INTERTAN Intertrochanteric Antegrade Nail procedure, designed to provide compression across the fracture site. It involves the insertion of a specialized screw, known as a lag screw, which is strategically placed through the nail and into the fractured bone. This process contributes significantly to the overall stability and healing of the fracture.
The surgeon uses a guide drill to create a pilot hole for the lag screw, ensuring accurate placement and minimizing the risk of damaging surrounding tissues. The lag screw is then inserted using a specialized driver, ensuring secure engagement within the bone and achieving the desired level of compression. The position and depth of the lag screw are carefully monitored using fluoroscopy, ensuring optimal placement and effectiveness.
The lag screw provides a strong connection between the bone fragments, promoting bone healing and reducing the risk of displacement. It also contributes to the overall stability of the fracture, allowing for early weight-bearing and promoting a quicker recovery for the patient. The successful insertion of the lag screw plays a pivotal role in the success of the TRIGEN INTERTAN procedure.
Postoperative Care
Following the TRIGEN INTERTAN Intertrochanteric Antegrade Nail surgery, a comprehensive postoperative care plan is implemented to promote healing, prevent complications, and facilitate a smooth recovery. This plan typically includes a period of non-weight-bearing immobilization, often with the assistance of crutches or a walker, to allow the fracture to heal properly. Regular follow-up appointments with the surgeon are scheduled to monitor progress, assess healing, and adjust the care plan as needed.
Pain management is a key aspect of postoperative care, often involving medication, physical therapy, and other modalities. Physical therapy plays a crucial role in regaining range of motion, strength, and mobility, helping patients regain their functional independence. As healing progresses, weight-bearing restrictions are gradually lifted, allowing patients to gradually resume normal activities.
The duration of postoperative care varies depending on individual factors such as age, overall health, and fracture complexity. However, close monitoring, adherence to the care plan, and open communication with the healthcare team contribute significantly to a successful outcome and a return to a fulfilling lifestyle.
