Background: Atypical Hangman's fractures may involve bilateral C2 pedicle fractures. Surgical fixation is often required to prevent instability and neurological impairment. The Judet technique, involving transpedicular screw fixation, offers a targeted approach to stabilize C2 pedicle fractures while preserving cervical motion.
Method: This article presents a neuronavigation-guided modification of the Judet technique for C2 pedicle screw placement. Advanced intraoperative computed tomography (CT) imaging, virtual trajectory planning and intraoperative navigation guidance provide surgical precision and patient safety.
Conclusion: Neuronavigation can improve the classical Judet technique, enhancing clinical safety and accuracy in fixation of C2 pedicle fractures. This minimally invasive/mini-open approach preserves C1-C2 mobility and reduces complications.

Structural defects and biological inertness significantly impair the integration of titanium alloy implants and bone tissues. In spinal internal fixation, the issue of pedicle screw loosening or fracture caused by poor integration urgently needs solving. In this study, we utilized 3D printing technology to custom fabricate a structurally optimized porous pedicle screw with the aim of enhancing bone regeneration and integration at the defect site, thereby enhancing the biological fixation of the implant .

Introduction: The Schanz screw system was developed for manual reduction of traumatic sagittal deformity of thoracic and lumbar vertebral fracture. The aim of this study was to evaluate clinical and radiological effectiveness of this system in the surgical treatment of thoracolumbar burst fractures (TLBFs) with severe kyphotic deformity without neurological deficit.
Materials And Methods: A retrospective analysis was conducted on 101 patients who underwent short posterior fixation with transpedicular Schanz screws between 2012 and 2022 for single-level (T12 or L1) TLBFs.

Case: A 46-year-old male patient presented with shoulder pain, limited range of motion, and loss of sensation for a year after undergoing hemiarthroplasty for a proximal humerus fracture. Workup demonstrated a greater tuberosity nonunion and deltoid paralysis secondary to upper trunk brachial plexopathy. The pectoralis major (PM) for deltoid transfer successfully restored shoulder function and resolved pain without requiring any subsequent intervention.

Patient integrity and implant primary stability can be jeopardized when cortical breaches caused by either the pedicle finder (PF) or the implant occur during pedicle screw placement. The aim of this study was to evaluate the potential of impact analysis performed on the PF and on the surgical screwdriver (SS) as a method to detect bone perforations during spinal instrumentation surgery. An indicator was derived from the temporal variation of the impact force signal recorded by an instrumented hammer (IH) impacting the surgical instruments.
