Latarjet procedure versus iliac crest autograft transfer for anterior shoulder instability: a systematic review and meta-analysis of comparative studies.

Background: Anterior shoulder instability with glenoid bone loss presents a challenge in orthopedic surgery. The Latarjet and iliac crest bone graft transfer (ICBGT) procedures are commonly employed for its management, but direct comparative evidence is insufficient.

Methods: Following PRISMA guidelines, a comprehensive search of PubMed, EMBASE, Cochrane Library, and Web of Science was conducted.

Three-dimensional anatomic analysis and navigation templates for C1 pedicle screw placement perpendicular to the coronal plane: a retrospective study.

Objective: To explore the corridor for atlas pedicle screw placement perpendicular to the coronal plane and to develop patient-specific navigation templates for pedicle screw placement.

Methods: This study is a retrospective analysis. A total of 71 patients (41 males and 30 females) were involved in this study from June 2016 to June 2018, and they were divided into a template group (39 patients) and a conventional group (32 patients).

3D-Printed Screw-Rod Auxiliary System for Unstable Atlas Fractures: A Retrospective Analysis.

Objective: To develop and validate the efficacy of a 3D-printed screw-rod auxiliary system for unstable atlas fractures.

Methods: This research is a retrospective analysis, and a total of 14 patients, including 11 males and three females, were enrolled in our hospital from January 2017 to March 2019 who underwent occipitocervical fusion assisted by the 3D-printed screw-rod auxiliary system were reviewed, and with an average age of 53.21 ± 14.
