How to measure screw length using drill bit

It is seen that while treating fractures surgically using plating one of the challenge is to measure exact screw size to fix the fracture. Various modalities are being practiced like use of depth gauge, (Williams and Roaf, 1973) fluoroscopic guidance and clinical experience. Our study shows that among all methods used, there is one more method that we are using since 3 years (2014—2017) has much more reliability and also no need of any external appliance to depend upon. The method named by us as drill bit method proved to be very much reliable in assesessing exact screw length.
