Evaluation of osseous integration of titanium orthopedic screws with novel SLA treatment in porcine model. [PDF]
The success of many endosseous implants in orthopaedic and dental applications depends on the surface characteristics, as they affect osseous integration.

In vitro and in vivo evaluations of nano-hydroxyapatite/polyamide 66/glass fibre (n-HA/PA66/GF) as a novel bioactive bone screw. [PDF]
In this study, we prepared nano-hydroxyapatite/polyamide 66/glass fibre (n-HA/PA66/GF) bioactive bone screws. The microstructure, morphology and coating of the screws were characterised, and the adhesion, proliferation and viability of MC3T3-E1 cells on ...

Developments in Modelling Bone Screwing [PDF]
Abstract INTRODUCTION: A torque-rotation model of the bone-screwing process has been proposed. Identification of model parameters using recorded data could potentially be used to determine the material properties of bone. These properties can then be used to recommend tightening torques to avoid over or under-tightening of bone screws ...

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

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

Double-screw and quadruple-button fixation for the glenoid: Latarjet versus bone block applications
Background: The Latarjet and bone block procedures can be secured with screws or cortical buttons. The purpose of this biomechanical study was to compare quadruple buttons vs. double screws for fixation of anterior glenoid bone grafts.
