Speed-torque relationship for self-tapping bone screw insertion

open access: yes, 2021
Bone screws are used for fixing implants and stabilizing fractures. Correct torquing of these screws is important for positive patient outcomes. A previously proposed model-based system may increase the accuracy of bone screw insertion, but this depends on the accuracy of the model.

Are Self-Drilling, Self-Tapping Screws Effective in Anterior Cervical Fusion Surgery? One Surgeon’s Experience with 50 Consecutive Patients

open access: yesJournal of Spine Practice
Purpose Even though plate and screw designs in anterior cervical discectomy and fusion (ACDF) have evolved to improve fusion stability and enhance patient outcomes, some argue that pre-tapping remained the best option. The purpose of this study is to
