Comparison of the Pullout Strength of Pedicle Screws According to the Thread Design for Various Degrees of Bone Quality

Applied Sciences, 2019
Although dual-threaded pedicle screws have been developed, the advantages over single-threaded screws remain controversial. We aimed to investigate the biomechanical performance of two types of dual-threaded pedicle screw by comparing their pullout ...

Cortical bone trajectory fixation cause low compression force in anterior vertebral column

North American Spine Society Journal, 2022
Background: The cortical bone trajectory (CBT) screws follow a caudocephalad and lateral path from the pedicle to the vertebral body. The bone fusion rate of CBT fixation is equal to or lower than conventional pedicle screw fixation.

Effect of sonic hedgehog/β-TCP composites on bone healing within the critical-sized rat femoral defect [PDF]

, 2013
The creation of entirely synthetically derived bone substitute materials which are as effective as autologous bone grafts is desirable. Osteogenesis involves the concerted action of several proteins within a signaling cascade.

Impact of bone density and integrated screw configuration on standalone anterior lumbar interbody construct strength

North American Spine Society Journal
Background: In anterior lumbar interbody fusion (ALIF), the use of integrated screws is attractive to surgeons because of the ease of implantation and no additional profile.

A new concept for implant fixation: bone-to-bone biologic fixation [PDF]

European Cells & Materials, 2015
Many attempts have been made to reduce complications of bone implant, such as pedicle screw loosening. To address this problem, the authors suggest a new concept of bone-to-bone biologic fixation using recombinant human bone morphogenetic protein-2 ...
