The battery drills we use as a base for our shrouded orthopaedic drills have adjustable torque settings.
While it is advised that the final tightenening of the screw is performed by hand, much time and effort can saved by power driving.
Risks are low, particularly in the proximal tibia.
To power drive using our drill we have created two hex driver extensions to fit into a standard Jacobs chuck. Use 2.5 hex for 2.7, 3.5 and 4.0mm screws.
