摘要: The technique for placement of orthopedic hardware remains unchanged despite technological advances. surgeon controls drill bit speed and advancement, which risks overpenetration, or plunge. Measurement is performed as an additional step, introducing measurement error increasing operative time. A dual-motor was created to control variables combine drilling into a single step. purpose this study determine whether could reduce errors while the hardware. Five surgeons drilled measured 10 holes with standard in randomized bicortical bone blocks. blocks were placed on ballistic gels, left defect from overpenetration that be calibrated gauge. accuracy determined by depth gel compared between groups. Finally, time collected Overpenetration (0.5±0.3 mm) significantly less than (8.4±1.9 (P<.0001). Depth (0.6±0.3 (2.6±0.5 Drilling (6.0±2.2 seconds) (13.4±3.9 Use reduced improved accuracy, spent during [Orthopedics. 2020;43(5):e465-e470.].
