Inferomedial cortical bone contact and fixation with calcar screws on the dynamic and static mechanical stability of proximal humerus fractures

Journal of Orthopaedic Surgery and Research, 2019
Background This study aimed to explore the effect of retaining inferomedial cortical bone contact and fixation with calcar screws on the dynamic and static mechanical stability of proximal humerus fractures treated with a locking plate.

Posterior transodontoid fixation: A new fixation (Kotil) technique

Journal of Craniovertebral Junction and Spine, 2011
Anterior odontoid screw fixation or posterior C1-2 fusion techniques are routinely used in the treatment of Type II odontoid fractures, but these techniques may be inadequate in some types of odontoid fractures.

Biomechanical evaluation of position and bicortical fixation of anterior lateral vertebral screws in a porcine model

Scientific Reports, 2023
Although an anterior approach with anterior lateral screw fixation has been developed for stabilizing the thoracolumbar spine clinically, screw loosening still occurs.

Factors influencing the pedicle screw fixation stability in patients with unstable lumbar and thoracolumbar spine injuries

Инновационная медицина Кубани, 2020
Background. One of the reasons for the lack of standardized approaches to treating lumbar and thoracolumbar spine traumatic injuries is inconclusive information on relative contribution of various factors to pedicle screw fixation stability.Objective. To

Reinforcement of Percutaneous Pedicle Screw Fixation with Hydroxyapatite Granules in Patients with Osteoporotic Spine: Biomechanical Performance and Clinical Outcomes

Medicina, 2022
In percutaneous pedicle screw (PPS) fixation of the osteoporotic spine, rigid screw fixation obtaining strong stabilization is important for achieving successful treatment outcomes. However, in patients with severe osteoporosis, it is difficult to obtain

Comparison of Clinical and Radiological Outcomes of Intramedullary Screw versus Plate-and-Screw Fixation in Lateral Malleolus Fractures:A Prospective Randomized Controlled Trial

Arcades of Medicine
Lateral malleolus fractures are common injuries, and surgical fixation is indicated in unstable fracture patterns. Plate-and-screw fixation has traditionally been considered the standard method; however, intramedullary screw fixation has emerged as a ...

Biomechanical study of C1 posterior arch crossing screw and C2 lamina screw fixations for atlantoaxial joint instability

Journal of Orthopaedic Surgery and Research, 2020
Background The biomechanics of C1 posterior arch screw and C2 vertebral lamina screw techniques has not been well studied, and the biomechanical performance of the constructs cannot be explained only by cadaver testing.
