Study of Nail Group Efficiency on Sandy Soil Using Large Scale Pull-out Box [PDF]

open access: yesJournal of Rehabilitation in Civil Engineering, 2022
The present study aims at investigating the pull-out resistance efficiency of single and double nails. In sandy soils, where the distance between nails is less than the minimum required distance, the pull-out resistance is reduced.

A study on the use of the Osstell apparatus to evaluate pedicle screw stability: An in-vitro study using micro-CT. [PDF]

open access: yesPLoS ONE, 2018
Pull-out force and insertion torque have not been generally used as intraoperative measures for the evaluation of pedicle screw stability because of their invasiveness.

Is the pull-out force of the Meniscus Arrow in bone affected by the inward curling of the barbs during biodegradation? An in vitro study [PDF]

open access: yes, 2009
Background: Inward curling of the barbs of Meniscus Arrows during degradation was observed in a previous study, in which swelling, distention, and water uptake by Meniscus Arrows was evaluated.

Experimental and Analytical Study on Pull-out Force of Steel Fiber-Reinforced Concrete Blocks

open access: yesDiyala Journal of Engineering Sciences, 2022
Reinforcing bar bonding in concrete is essential for reinforcing bar anchoring and reinforced concrete cracking control. A pull out test of a reinforcing bar embedded in a concrete block is commonly used to determine it. When compared to plain concrete,

Bone density optimized pedicle screw instrumentation improves screw pull-out force in lumbar vertebrae [PDF]

open access: yesComputer Methods in Biomechanics and Biomedical Engineering, 2021
Pedicle screw instrumentation is performed in the surgical treatment of a wide variety of spinal pathologies. A common postoperative complication associated with this procedure is screw loosening. It has been shown that patient-specific screw fixation can be automated to match standard clinical practice and that failure can be estimated preoperatively ...
