Biomechanical Properties of Novel Lateral Hole Pedicle Screws and Solid Pedicle Screws: A Comparative Study in the Beagle Dogs.

Objective: Although pedicle screws are widely used to reconstruct the stability of the spine, screw loosening is a common complication after spine surgery. The main objective of this study was to investigate whether the application of the hollow lateral hole structure had the potential to improve the stability of the pedicle screw by comparing the biomechanical properties of the novel lateral hole pedicle screws (LHPSs) with those of the solid pedicle screws (SPSs) in beagle dogs.

Methods: The cancellous bone of the distal femur, proximal femur, distal tibia, and proximal tibia were chosen as implantation sites in beagle dogs.

Clinical characteristic and surgical treatment of traumatic lumbar spondylolisthesis: A series of 28 patients.

Objective: To explore the clinical characteristics and the short-term efficacy of posterior operation for traumatic lumbar spondylolisthesis.

Methods: All 28 patients (between January 2013 and June 2018) were treated with lumbar pedicle screw fixation combined with posterior intervertebral fusion. The clinical data and imaging materials of these patients were retrospectively analyzed.
