Dunitech Claw Technology Dunitech leads innovational systems, and aims to supply options for the surgeons to excel at their expertise. Claws are a novelty solution on distal locking systems designed to support the orthopedic trauma community. Claws are titanium pins that act as anchors to provide a stable fixation, as well as other superior operative parameters.

The Claws are made from titanium, and mechanically deploy from within the nail and lag screw. The Claws penetrate through the cancellous bone, and anchor the nails and lag screw in the cortical bone. We focus on operative parameters that are vital for to success of the fracture treatment. Dunitech’s innovative devices allow healthcare professionals to reduce surgical time as well as the risk of pre - and postoperative complications. By eliminating the distal incisions, the Claws significantly reduce the radiation exposure and blood loss. Increased stability Shorter operative time Lower radiation...

Claws in Action The Claws’ performance was evaluated using a series of biomechanical tests.1 All Claws were successfully retracted after every test. (A) reliably retractable! Conventional systems are subjected to screw breakage, screw headwear and drill bit breakage that may prevent the nail to be removed. Dunitech Claws are deployed within the nails from precise holes in a tight fit, preventing empty spaces for bone ingrowth. 1. The studies presented in the subsequent pages were performed at the following labs; Knight Mechanical Testing, 6016B Highview Drive, Fort Wayne, IN 46818 and Philip...

Rotational Stability Cumulative Rotation(deg) Rotational Stability In unstable subtrochanteric fractures Claws provide superior rotational stability. After 10,000 cycles, the nail settled in and remained fixed until 100,000 cycles. Axial Fatigue Claws Axial Fatigue Strength The average displacement observed at 1 million cycles was 0.74 mm. Cortical Screw Claw Axial Static Strength Claws resist to a higher force for a given displacement, compared to conventional stainless steel screws.

Get Better Stability! Claws have 6 points of contact with the cortical bone. The load is shared between those points, increasing the implant’s stability, and preventing secondary fractures and malunions. Less Radiation Exposure Claws significantly reduce the radiation exposure of the team in the operating room by avoiding the need of targeting the distal hole, reaming and inserting a screw for distal locking.1,2 Fewer Incisions The nail is anchored by the Claws deployed from within the medullary canal. By avoiding extra incision, there will be fewer surgical scars, lower blood loss and shorter...

Shorter operative time Less Radiation Exposure Fewer Incisions

Lag Screw Claw Technology The internal fixation device should promote good rotational stability to allow for quick regeneration of the bone. Fracture gap or distraction are also important causes of nonunion. To tackle these challenges, Dunitech’s Lag Screw utilizes the Claw Technology. It presents three times more rotational stability and a two-fold increase in compression when compared to conventional systems.1

3x More Rotational Stability Four retractable Claws anchor the lag screw into the cortical bone of the femoral head-neck junction for superior control. Peak Compressive Forces Standard Peak Torque *Study made in University of Florida Biomechanics Laboratory Rotational Stability When deployed, the Claws’ span is more than twice the diameter of the lag screw alone. The engagement of the Claws within the cortical bone at the junction between femoral head and neck leads to a three-time increase in the rotational resistance when compared to conventional screws.1 Neon’s lag screw is equipped with Claw...

Neon Proximal Femoral Nail Neon is a titanium nail designed for the treatment of proximal femoral fractures. By using the Claw technology in the distal end and lag screw, this nail allows surgeons to perform at their best in the operating room. Also, Neon has Short and Long versions with fully cannulated bodies compatible with guide-wire applications. Indications Intertrochanteric fractures Stable and unstable pertrochanteric fractures High subtrochanteric fractures without shaft extension. Low subtrochanteric fractures (Neon Long Nails only) Osteoporotic fractures Pathologic / impending pathologic...

Navy A/ R Femoral Nail Navy is a titanium nail designed for the treatment of femoral fractures. The Claw technology supports the surgeon to reach superior operative parameters. Navy is compatible with Antegrade and Retrograde operating techniques, giving flexibility for the surgeon to choose the most appropriate approach for each fracture. The nail has a fully cannulated body, compatible with guide-wire applications and offers 10mm compression range. Indications Femoral Shaft Fractures Ipsilateral hip / shaft fractures Ipsilateral femur / tibia fractures (floating knee) Supracondylar fractures...
