Osteoporosis is a medical condition affecting men and women of different age groups and
populations. The compromised bone quality caused by this disease represents an important …

This book provides a comprehensive review of the biomedical applications of biodegradable
magnesium and its alloys. It discusses the basic concepts of biodegradation mechanisms as …

It was supposed that auxetic structure with negative Poisson's ratio (NPR) expands under
stretch and could enhance the screw-bone fixation. In this study, the novel auxetic structure …

The incidence of screw loosening, migration, and pullout caused by the insufficient screw-
bone fixation stability is relatively high in clinical practice. To solve this issue, the auxetic unit …

Pedicle screws are widely used for the treatment of spinal instability by spine fusion. Screw
loosening is a major problem of spine fusion, contributing to delayed patient recovery. The …

Background Pedicle screws are widely used in fusion surgery, while screw loosening often
occurrs. An auxetic structures based pedicle screw was proposed to improve the bone …

OBJECTIVE Proximal junctional kyphosis (PJK) is, in part, due to altered segmental
biomechanics at the junction of rigid instrumented spine and relatively hypermobile non …

The strength between the cortical screw and bone following an orthopaedic implant surgery
is an important determinant for the success of osteosynthesis. An excessive axial cutting …

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 …
