Pullout Strength of Epoxy Anchors Installed Underwater
… a submerged anchor installation has on the pullout strength of epoxy anchors. Two different epoxies were tested at embedment depths of two, four, and six bar diameters. These tests utilized three distinct installation procedures under dry and submerged conditions. The testing program …

Optimization of Pedicle Screw Depth in the Lumbar Spine: Biomechanical Characterization of Screw Stability and Pullout Strength
… remain in our understanding of the biomechanical strength of lumbar pedicle screw fixation as it relates to screw sizing and placement. Biomechanical analyses examining ideal pedicle screw depth with current pedicle screw technology are limited. In the osteoporotic spine, optimized pedicle screw …

Frontal Plane Humeral Elevation Effects on the Pullout Strength of Suture Anchors Used in Rotator Cuff Repair
… eyelet breakage, suture failure, and anchor pullout. These failure modes necessitate intervention to reattach the tendon thus prolonging the healing period. Identifying and minimizing these failure modes will ensure optimum healing. There are two goals of this study. Firstly, the paper will …

Screw fixation of implants to the spine
… in osteoporotic bone because of its reduced strength. This research aimed to investigate screw fixation techniques in the spine. A questionnaire study, representing British and Irish spine surgeons, confirmed the potential for a simple screw positioning device and identified the need for an …

Strengthening of RC slabs with penetrations using unanchored and anchored FRP composites
… slab which will then require the installation of strengthening. Traditional methods of strengthening RC slabs with penetrations, such as the addition of extra supports or bolted steel plates, can be expensive and cumbersome. Such traditional methods can however be replaced by the bonding of high …

Osseointegration of a Cementless Total Knee Arthroplasty in a Murine Model of Glucocorticoid Induced Osteoporosis
… regeneration, osseointegration and biomechanical strength. The mouse model used in this study consists of a laser sintered titanium beaded tibial component (2mm long, 1mm diameter) from which biomechanical pullout strength and bone ingrowth can be readily measured. The goal of the current study …

Design and Development of a Novel Expanding Pedicle Screw for Use in the Osteoporotic Lumbar Spine
… screws failed to demonstrate improved screw pullout; however, differences may be observed in other loading modes (i.e., toggle) and further design modifications and improvements in post-build machining may provide beneficial enhancements.

Structural Behaviour of Self Consolidating Steel Fiber Reinforced Concrete Beams
… fail in shear before reaching its full flexural strength. This type of failure is sudden in nature and usually disastrous because it does not give sufficient warning prior to collapse. To prevent this type of shear failure, reinforced concrete beams are traditionally reinforced with stirrups. …
