How Pilot Hole Size Affects Screw Pullout Strength in Normal and Osteoporotic Bone Models: A Biomechanical Study
ObjectiveFailure of screw purchase is a major concern in both normal and osteoporotic bone that can lead to many complications. The goal of this study was to assess how an under-drilled pilot hole diameter affected screw pullout strength in both normal density and osteoporotic bone. MethodsSeventy-two Synthes stainless steel self-tapping cortical screws (50 mm length […]
