A Biomechanical Comparison of A Novel Thoracic Screw Fixation Method: Transarticular Screw Fixation versus Traditional Pedicle Screw Fixation

Neurosurgery, 2011
Transarticular screw fixation is used in the upper cervical and lumbar spine to achieve posterior spinal stability, and its biomechanical performance has been proven to be similar to that of pedicle screw fixation. However, few studies have reported the use of transarticular screw fixation in the upper thoracic spine.To biomechanically compare ...

Revision of Syndesmosis Screw Fixation

Foot & Ankle Specialist, 2019
Background: Many syndesmosis screw fixations do not achieve success at the first attempt. Currently, there are no data available to evaluate revision of syndesmosis screw failure. Methods: A total of 160 consecutive patients who underwent syndesmosis screw fixation from 2014 to 2016 were reviewed.

Force measurements in screw fixation

Journal of Biomechanics, 1976
Abstract An entire range of screw sizes and types from one manufacturer (Synthes, Switzerland) along with two experimental sizes were tested in bovine cancellous bone to measure torque of insertion, screwdriver pressure, axial compression generated by the screw, screw breaking strength and efficacy of various head types.

Compression Screw Fixation of the Syndesmosis

Foot & Ankle International, 2012
Background: Screw fixation of syndesmotic injuries facilitates ligament healing and restoration of ankle stability, but little information regarding screw performance is available. This study quantified the reduction obtained with three common 2-screw configurations using different methods of reduction and novel methods of subsequently provoking and ...

Laminar screw fixation of the axis

Journal of Neurosurgery: Spine, 2008
Object Laminar fixation of the axis with crossing bilateral screws has been shown to provide rigid fixation with a theoretically decreased risk of vertebral artery damage compared with C1–2 transarticular screw fixation and C-2 pedicle screw fixation. Some studies, however, have shown restricted rigidity of such screws compared with C-2 pedicle screws,

Screw fixation of infraorbital implants

Journal of Oral and Maxillofacial Surgery, 1984
Facial skeletal defects can be corrected by implanting a variety of materials beneath the soft tissue. Fixation of these implants to the skeleton can be time-consuming. In general, wiring techniques require additional access for placement of the implant, especially when the need for exit holes to retrieve the wires is considered.

Screw Fixation of Silicone Implants

Annals of Plastic Surgery, 1987
A simple and safe procedure for fixation of silicone prostheses is presented. Two screws ensure accurate location, helping to avoid displacement and probably reducing the incidence of bone damage.

Biomechanical Analysis of Latarjet Screw Fixation: Comparison of Screw Types and Fixation Methods

Arthroscopy, 2017
Purpose To compare the initial fixation stability, failure strength, and mode of failure of 5 different screw types and fixation methods commonly used for the classic Latarjet procedure. Methods Thirty‐five fresh‐frozen cadaveric ...

Complications of the Variable Screw Plate Pedicle Screw Fixation

Spine, 1991
In this study, 124 consecutive cases of posterior spinal fusion with variable screw plate fixation were reviewed. In 33 patients (27%), 41 complications were identified. Urinary tract infection without sequelae developed in 13 patients. Dural tear occurred in seven patients and wound hematoma in five.
