Alendronate Inhibits Bone Resorption at the Bone-screw Interface

Clinical Orthopaedics & Related Research, 2005
In the current study, we investigated whether the systemic administration of alendronate, a third-generation bisphosphonate, suppressed the loosening of screws at the bone-screw interface. We systemically administered alendronate to rats fitted with external fixators.

Cancellous Screws Are Biomechanically Superior to Cortical Screws in Metaphyseal Bone

Orthopedics, 2016
Cancellous screws are designed to optimize fixation in metaphyseal bone environments; however, certain clinical situations may require the substitution of cortical screws for use in cancellous bone, such as anatomic constraints, fragment size, or available instrumentation.

Biomechanical comparison of bone-screw–fasteners versus traditional locked screws in plating female geriatric bone

Injury, 2020
To biomechanically compare plated constructs using nonlocking bone-screw-fasteners with interlocking threads versus locking screws with traditional buttress threads in geriatric female bone.Eleven matched pairs of proximal and distal segments of geriatric female cadaveric tibias were used to create a diaphyseal fracture model.

Fully Threaded Versus Partially Threaded Screws: Determining Shear in Cancellous Bone Fixation.

Journal of Foot and Ankle Surgery, 2015
Many researchers have studied and compared various forms of intraosseous fixation. No studies have examined the effects of shear through stiffness and failure strength of a fully threaded versus a partially threaded screw.

Bone screws and plates in orthognathic surgery

International Journal of Oral Surgery, 1982
The almost universal use of bone plates and screws in orthognathic surgical procedures is surveyed. Based upon considerable personal experience, it is advocated that this technique should be used for better stabilization of the fragments, leading to faster bone healing and therefore to less relapse.

Bone Strength

The Journal of Bone & Joint Surgery, 1972
1. In dogs, redrilling a screw hole after removal of the screw did not improve final repair as judged by both histological examination and biomechanical testing.2. The screw holes, despite the radiolucency apparent on roentgenograms were rapidly filled with dense woven bone, and then were slowly ...

Alendronate Improves Screw Fixation in Osteoporotic Bone

The Journal of Bone & Joint Surgery, 2007
Animal studies have demonstrated the efficacy of the use of bisphosphonates to enhance screw fixation in bone. In this prospective, randomized study of pertrochanteric fractures treated with external fixation, we tested whether systemic administration of bisphosphonates would improve the fixation of hydroxyapatite-coated screws implanted in ...

Strength comparison of allogenic bone screws, bioabsorbable screws, and stainless steel screw fixation

The Journal of Foot and Ankle Surgery, 2002
Allogenic bone screws are new to the fixation market and have yet to be tested against current fixation materials. An in vitro comparison of the same sizes of stainless steel, bioabsorbable, and allogenic bone screws was undertaken to assess screw resistance to the forces of bending, pullout, and shear.
