As Dunitech believe that the best way to understand the safety and performance of our devices is through clinical studies. We are always looking for updated publications that help us guide our Research and Development department on the improvement of our devices.
Zehir et al. performed a study in 2015 comparing PFNA (Synthes), InterTan (Smith and Nephew) and ODI's Distal fix, which utilizes an equivalent of the Claw system, the Talons. The authors have studied patients with AO/OTA 31-A2 and 31-A3 fractures and they have concluded the Talon System offered a very steep learning curve, lower cut-out rates when compared to PFNA and shorter operative time when compared to InterTan.

In a retrospective study by Çamurcu et al. in 2017, the authors compared an equivalent system to Claw with conventional locked nails in Tibial fractures. The results point to significant reduction in operative time and radiation exposure when using Claw system.

Bramlet has compared the biomechanical performance of the lag screw with an equivalent system to Claw fully deployed of not deployed. The author has concluded that the deployment of the Claws increases the compression by two times and the causes a 3-fold increase in torsional strength.
