To contrast the clinical and radiologic outcomes and adverse events of anterior cervical discectomy and fusion (ACDF) with a single cervical disc arthroplasty design, the polyurethane on titanium unconstrained cervical disc (PTUCD). ⋯ According to this review, PTUCD arthroplasty showed a global superiority to ACDF in clinical outcomes. The impact of both surgical techniques on the cervical spine (radiological spine deterioration and/or complications) was more severe in patients undergoing ACDF. However, the rate of revision surgeries at any cervical level was equivalent for ACDF and PTUCD arthroplasty.

Use of intraoperative fluoroscopy for the safe placement of C2 laminar screws: technical note.
Rigid fixation of the atlantoaxial joint can be quite challenging due to complex anatomic variants. Numerous techniques have evolved over time, improving the surgeon's adaptability. The recent advent of C2 laminar screws adds to the surgeon's armamentarium, but is not without its own set of limitations. Risk of ventral laminar breach with possible spinal cord injury, CSF leak, or poor bony fixation have led some to recommend prefabricated models or expensive intraoperative spinal navigation to aid screw placement. The purpose of this report is to detail how the use of intraoperative fluoroscopy can be used to aid in the safe placement of C2 laminar screws. ⋯ Use of intraoperative fluoroscopy is an easy and safe method for the placement of C2 laminar screws. Given its use of readily available equipment, this method can be implemented without significant pre-planning, or as an impromptu salvage maneuver.

In this narrative review, we aim to give an update on the anatomic fundamentals of endoscopic assisted surgery to the craniocervical junction (transnasal, transoral and transcervical), and to report on the available clinical results. ⋯ Transoral (microsurgical or video-assisted) approach with sparing of the soft palate still remains the gold standard compared to the "pure" transnasal and transcervical approaches due to the wider working channel provided by the former technique. Transnasal endoscopic approach alone appears to be superior when the CVJ lesion exceeds the upper limit of the inferior third of the clivus. Combined transnasal and transoral procedures can be tailored according to the specific pathological and radiological findings.
