Intramedullary Compression Screw Fixation of Proximal Phalangeal Fractures: A Systematic Literature Review

, 2020
Proximal phalangeal fractures have traditionally been fixed via either Kirschner wires or dorsal plating. Concerns regarding lack of compression and potential for infection with wire fixation, and adhesion formation and stiffness with plating, have lead ...

Biomechanical comparison of pedicle screw fixation strength in synthetic bones: Effects of screw shape, core/thread profile and cement augmentation.

PLoS ONE, 2020
Pedicle screw loosening resulting from insufficient bone-screw interfacial holding power is not uncommon. The screw shape and thread profile are considered important factors of the screw fixation strength. This work investigated the difference in pullout

A comparison of the biomechanical properties of three different lumbar internal fixation methods in the treatment of lumbosacral spinal tuberculosis: finite element analysis

Scientific Reports, 2023
There are various internal fixation methods in treating lumbosacral spinal tuberculosis. The study compared the stability and stress distribution in surrounding tissues/implants, such as discs, endplates and screw-rod internal fixation system, etc.

Biomechanical comparative analysis of conventional pedicle screws and cortical bone trajectory fixation in the lumbar spine: An in vitro and finite element study

Frontiers in Bioengineering and Biotechnology, 2023
Numerous screw fixation systems have evolved in clinical practice as a result of advances in screw insertion technology. Currently, pedicle screw (PS) fixation technology is recognized as the gold standard of posterior lumbar fusion, but it can also have

Minimally invasive cervical pedicle screw fixation via the posterolateral approach for metastatic cervical spinal tumors

Spine Surgery and Related Research, 2017
Background: To avoid lateral misplacement of midcervical pedicle screws, we developed a method for Minimally Invasive Cervical Pedicle Screw (MICEPS) fixation via a posterolateral approach.

Cannulated screw Kirschner-wire fixation for Milch II lateral condyle fractures in a paediatric sawbone model: A biomechanical comparison

Journal of Children's Orthopaedics, 2018
Purpose Lateral condyle fractures of the humerus are common in the paediatric population, accounting for up to 20% of elbow fractures. Traditional management involves internal fixation with Kirschner (K)-wires, however, this has been associated with ...

Biomechanical Study Examining the S2 Alar Iliac Screw Insertional Torque

Global Spine Journal, 2016
Introduction Prior biomechanical studies have examined the role of the iliac screw in lumbosacral fixation [Lebwohl, 2002; Cunningham, 2010] and while found to be significant, the ideal screw device and fixation technique have yet to be identified.

Can Resorbable Fixation Screws Replace Titanium Fixation Screws? A Nano-Indentation Study

Journal of Oral and Maxillofacial Surgery, 2016
The aim of this study was to compare the nano-hardness and elastic modulus of titanium and resorbable screws and determine whether resorbable screws could completely replace titanium screws.The mechanical properties (nano-hardness and decreased elastic modulus) of TriMed titanium, resorbable Inion CPS, and Synthes RapidSorb samples were measured using ...

Defining a Safe Zone for Percutaneous Screw Fixation of Posterior Malleolar Fractures

, 2021
Posterior malleolar fractures require fixation to confer stability to the ankle. Although some have suggested that fractures involving less than 25% of the articular surface require no intervention, estimation of malleolar size on plain imaging is ...
