Product Description
The Series II jig provides expanded locking options, including oblique and anteroposterior trajectories, to ensure maximum stability in very short distal fragments.
Includes specialized compression bolts and drivers designed to close intercondylar gaps, ensuring anatomical reduction of the joint surface prior to final locking.
Features an optimized carbon fiber targeting arm with increased clearance, providing unobstructed fluoroscopic views of the condyles and the joint line in both AP and lateral planes.
Equipped with a refined set of low-profile trocars and protection sleeves that allow for easier navigation through the patellofemoral joint with minimal surgical trauma.
The set is primarily indicated for AO/OTA Type 33-C fractures, where the enhanced multi-planar locking and compression tools are required for articular reconstruction.
Specifically indicated for stabilizing fractures above a stable TKA, where the nail is advanced through the prosthetic box using specialized entry tools included in the Series II.
Indicated for complex revision cases where previous fixation has failed; the set’s robust reaming and insertion tools are ideal for navigating sclerotic canals and scarred tissue.
Contains the specialized tools indicated for "floating knee" injuries or segmental fractures where a retrograde approach allows for efficient stabilization of the distal and shaft fragments.

The Expert Reversed Femoral Intramedullary Nail Instrument Set-II is an advanced surgical system designed for the retrograde stabilization of complex distal femoral fractures. This Series II set is an "enhanced" version of standard retrograde systems, providing a more comprehensive range of tools for multi-planar locking and anatomical fracture reduction. It functions by providing a specialized entry corridor through the knee joint into the medullary canal. The set includes a high-precision, carbon-fiber targeting jig that aligns perfectly with the nail's distal locking apertures, along with specialized compression bolts used to stabilize intercondylar splits. Manufactured from medical-grade 17-4PH stainless steel, the set is designed to provide maximum mechanical stability for fractures that are close to the articular surface of the knee.
This instrument set is primarily applied in the treatment of supracondylar and intercondylar femoral fractures where a retrograde approach is indicated. It is a critical application for periprosthetic fractures occurring above total knee replacements, as the Series II entry tools are specifically engineered to pass through the notch of most knee prostheses. The set is also applied in complex multi-fragmentary fractures where the distal bone fragment is too short for standard antegrade nailing. In clinical practice, the set is utilized with the patient in a supine position, where the multi-planar targeting arms are applied to guide screws in various directions (ML, AP, and oblique) to maximize fixation. Its enhanced compression tools make it an essential application for restoring joint congruity in intra-articular injuries.
The primary advantage of the TOOLMED Expert Reversed Femoral Set-II is the increased density of locking options provided by the redesigned targeting jig. This offers a significant advantage in achieving "fixed-angle" stability in the distal femur, which is critical for preventing varus/valgus collapse. The inclusion of internal compression bolts is a major advantage, allowing the surgeon to pull intercondylar fragments together before final locking is completed. Another advantage is the radiolucent carbon fiber arm, which provides a key advantage by allowing clear, unobstructed fluoroscopic imaging of the entire distal femur. Furthermore, the Series II set’s reinforced inserter handles provide a significant advantage in durability, ensuring the system can withstand the high impact forces required during the treatment of sclerotic or high-energy trauma cases.
Biomechanically, the instrument set facilitates a rigid, internal load-sharing construct that is specifically optimized for the complex loading environment of the distal femur. The Series II targeting jigs are biomechanically designed to place locking screws in divergent planes, which significantly increases the construct's resistance to rotational and axial forces compared to parallel screw placement. The compression tools included in the set are biomechanically essential for restoring the "hoop stress" of the distal femoral condyles, ensuring the articular surface is perfectly aligned. By enabling a high-density screw construct near the joint, the instruments help distribute physiological loads evenly across the distal femur, which is biomechanically critical for early patient mobilization and prevention of hardware failure.
The surgical technique begins with the knee flexed approximately 30-40 degrees. An entry point is established in the intercondylar notch using the set's specialized cannulated awl and guide wire. After reaming the medullary canal, the Expert Reversed Nail is mounted to the Series II inserter and advanced into the femur. The carbon-fiber targeting jig is attached, and if an intercondylar fracture is present, the set's compression bolt is used to achieve joint congruity. Multi-planar distal locking is then performed using the targeting arm to guide drill bits and screws through the nail. Finally, proximal locking is completed using the jig or a free-hand technique, and the end cap is secured with the dedicated driver to prevent bony ingrowth into the nail's internal threads.
Postoperative care for the instrument set involves a rigorous protocol for manual cleaning and high-temperature sterilization. After each procedure, the multi-planar targeting jig and all compression bolts must be fully disassembled and cleaned with pH-neutral detergents. The cannulated entry tools and protection sleeves require meticulous cleaning with specialized wire brushes and ultrasonic processing to remove all biological debris from the internal lumens. All components are then sterilized in a steam autoclave at 134°C. For the facility, it is critical to regularly inspect the targeting arm for alignment accuracy and to ensure the compression threads remain undamaged. Proper maintenance of the Series II set ensures that its high-precision tolerances are preserved, guaranteeing surgical accuracy for future complex retrograde nailing cases.
The TOOLMED Expert Reversed Femoral Intramedullary Nail Instrument Set-II is an essential system for modern retrograde trauma surgery. By providing advanced compression capabilities and multi-planar targeting precision, this set ensures that surgeons can stabilize even the most complex distal femoral and periprosthetic fractures with anatomical accuracy, leading to superior joint function and improved long-term outcomes for the patient.
