Release, reduction, and fixation of one-stage posterior approach for basilar invagination with irreducible atlantoaxial dislocation.

Purpose: We evaluate the efficacy, safety and indications of single stage posterior release, reduction, and fixation of basilar invagination (BI) with irreducible atlantoaxial dislocation (IAAD).

Materials And Methods: Seventeen patients with BI and IAAD consecutively underwent one-stage release, reduction, and fixation by a posterior approach from July 2000 to June 2015 were followed up for at least 12 months. There were 8 males.

Minimally invasive versus conventional fixation of tracer in robot-assisted pedicle screw insertion surgery: a randomized control trial.

Background: This study evaluated the minimal invasiveness, safety, and accuracy of robot-assisted pedicle screw placement procedure using a modified tracer fixation device.

Methods: Patients were randomly assigned to conventional fixation group (25 patients) and modified fixation group (27 patients).

Results: No baseline statistical difference was observed between the groups (P > 0.

Management of Mandibular Fractures Using Locking and Nonlocking Miniplates.

Purpose: The study proposed to determine the superiority between locking plate and nonlocking miniplate for mandibular fractures (MFs) treatment.

Methods: A comprehensive electronic search examining Medline-Ovid, Embase, and PubMed databases language without date was performed in February 2018. Inclusion criteria were studies in humans, including randomized controlled trials, controlled clinical trials, with the aim of comparing the 2 techniques.
