There are three basic concepts that are important to the biomechanics of pedicle screw-
based instrumentation. First, the outer diameter of the screw determines pullout strength …

Osteoporosis is the most common metabolic bone disorder. The National Osteoporosis
Foundation defines osteoporosis as “porous bone. a disease characterized by low bone …

Background Pilot hole preparation has been shown to have an impact on the short and long‐
term stability of the screw fixation constructs. Purpose Investigation and comparison of two …

Background Pull-out tests have been widely applied to orthopaedic devices such as pedicle
screws for the last decades. Despite their wide applicability, this particular pedicle screw …

Background context There is currently no reliable technique for intraoperative assessment of
pedicle screw fixation strength and optimal screw size. Several studies have evaluated …

Background context Rod contouring is frequently required to allow for appropriate alignment
of pedicle screw-rod constructs. When residual mismatch is still present, a rod persuasion …

Purpose To experimentally study the influence of pilot hole diameter (smaller than or equal
to the internal (core) diameter of the screw) on biomechanical (insertion torque and pullout …

Surface treatment interferes with the primary stability of dental implants because it promotes
a chemical and micromorphological change on the surface and thus stimulates …

Study design A detailed finite element analysis of screw fixation in the sacrum and pelvis.
Objective To biomechanically assess and compare the fixation performance of sacral and …

Aim: Patient-specific 3D-printed guides for pedicle screw insertion in spinal deformity
surgery offer an alternative to image-guided, robotic and free-hand methods. Different …
