Non-invasive quantification of lower limb mechanical alignment in flexion [PDF]

, 2014
Objective: Non-invasive navigation techniques have recently been developed to determine mechanical femorotibial alignment (MFTA) in extension. The primary aim of this study was to evaluate the precision and accuracy of an image-free navigation system ...

Repair of Microdamage in Osteonal Cortical Bone Adjacent to Bone Screw

PLoS ONE, 2014
Up to date, little is known about the repair mode of microdamage in osteonal cortical bone resulting from bone screw implantation. In this study, self-tapping titanium cortical bone screws were inserted into the tibial diaphyses of 24 adult male rabbits.

Osseointegration of Self-Drilling Titanium Screws in the Hole Smaller than the Screw Core in the Male Rabbit

Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca: Veterinary Medicine
Inserting orthopedic screws into a hole that is too small can produce excessive mechanical forces that cause osteocyte death and difficulty carrying out bone repair processes. The aim of the study was to evaluate the osseointegration of titanium screws 6

Biomechanical Evaluation of the Fixation Methods for Transcondylar Fracture of the Humerus:ONI Plate Versus Conventional Plates and Screws [PDF]

, 2010
We biomechanically evaluated the bone fixation rigidity of an ONI plate (Group I) during fixation of experimentally created transcondylar humerus fractures in cadaveric elbows, which are the most frequently observed humeral fractures in the elderly, and ...

Do newer-generation bioabsorbable screws become incorporated into bone at two years after ACL reconstruction with patellar tendon graft?: A cohort study.

Journal of Bone and Joint Surgery. American volume, 2014
BACKGROUND Bioabsorbable interference screws are used frequently for graft fixation in ACL (anterior cruciate ligament) reconstruction. The resorption properties of many available screws that are marketed as bioabsorbable are not well defined. The CALAXO

Fixation of displaced femoral neck fractures. A comparison between sliding screw plate and four cancellous bone screws.

Acta Orthopaedica Scandinavica, 1987
In a prospective, randomized trial, 104 consecutive patients with displaced femoral neck fractures were allocated either to fixation with a sliding screw plate or 4 ASIF cancellous bone screws. The patients were reexamined at fixed intervals to determine

Double-screw and quadruple-button fixation for the glenoid: Latarjet versus bone block applications

JSES International, 2020
Background: The Latarjet and bone block procedures can be secured with screws or cortical buttons. The purpose of this biomechanical study was to compare quadruple buttons vs. double screws for fixation of anterior glenoid bone grafts.

Assessing the Accuracy and Safety Thresholds of Patient-Specific Screw Guide Template System in Cervical and Thoracic Spine Surgeries Using DAST Measurements

Spine Surgery and Related Research
Introduction: To analyze the reliability of the newly developed patient-specific Screw Guide Template (SGT) system as an intraoperative navigation device for spinal screw insertion. Methods: We attempted to place 428 screws for 51 patients.
