Biomechanical Design and Analysis of Auxetic Pedicle Screw to Resist Loosening

Computers in Biology and Medicine, 2021
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-screw fixation by radial expansion of the screw body under tensile force to resist pulling out.

Pedicle Screw Loosening: A Clinically Relevant Complication?

European Spine Journal, 2015
Literature studies showed a very wide range of pedicle screw loosening rates after thoracolumbar stabilization, ranging from less than 1 to 15 % in non-osteoporotic patients treated with rigid systems and even higher in osteoporotic subjects or patients treated with dynamic systems.

Biomechanical Stability and Pedicle Screw Loosening

Journal of Biomechanics
Pedicle screws are widely utilized in spinal surgeries, yet postoperative loosening remains a major complication in clinical practice. A better understanding of the screw loosening mechanisms will aid the development of proper approaches to predict screw loosening and to reduce the loosening rate.

Prediction of Fatigue Loosening in Pedicle Screw Fixation

Advances in Bioengineering, 1995
Abstract A biomechanical study was performed to investigate factors that would affect fatigue strength of the pedicle screw fixation. Measured parameters included bone mineral density (BMD) of the vertebral body, pedicle height (PH), pedicle width (PW), and screw insertion torque (T).

Pedicle screw shift without loosening following instrumented posterior fusion: limitations of pedicle screw fixation

Neurosurgical Review, 2018
The disc angle at the fused segment is extended in operative prone position, but eventually returns to preoperative neutral position within 6 months to 1 year. This study aimed to assess pedicle screw (PS) shift without loosening to identify the mechanism of the change in disc angle after posterior fusion for degenerative lumbar spondylolisthesis (DLS).
