Pedicle Screws and Bone Mineral Density

Spine, 1994
Thirty-five consecutive patients who underwent surgeries for decompression, and one-level fusions with Cotrel-Dubousset pedicle screws for spinal canal stenosis were included in this study. The relationship between bone mineral density of the lumbar spine and the rate of successful fusion and screw problems was studied.Bone mineral density of the third

Fracture Fixation with Screws and Bone Plates

Veterinary Clinics of North America: Small Animal Practice, 1999
The treatment goal of fracture fixation is to restore the patient to normal function as quickly as possible. Fracture fixation can be accomplished by various means; fixation with screws and bone plates is not only a popular but a successful technique. In this article, the authors provide concepts that a surgeon must understand for successful screw and ...

Remodeling along the Bone-screw Interface

Journal of Orofacial Orthopedics / Fortschritte der Kieferorthopädie, 2008
The stability of cortical miniscrews depends on the contact between bone and implant. The aim of this study was to compare bone remodeling along the contact surface between the screw and bone with and without pre-drilling.Twenty-four FAMI miniscrews (length 10 mm, diameter 2 mm) were inserted into the mandibular alveolar process apical to the premolars

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.

Cortical Bone Screw Fixation

2017
Placement of lumbar fixation screws using the cortical bone trajectory is a novel and potentially valuable technique. In this chapter, we discuss the current literature on clinical outcomes and biomechanical properties of the cortical bone trajectory. We examine indications for which this trajectory may be beneficial compared to a traditional pedicle ...
