The traditional teaching has been that proper function of a cervical disc replacement is dependent upon appropriate placement, which includes centering the device in the coronal plane. The purpose of this study was to identify the most reliable anatomical landmark for determining midline placement of an implant within the cervical disc space under fluoroscopy. ⋯ The results of this investigation suggest that the tip of the uncinate and the medial border of the pedicle are more accurate measures of midline in the cervical spine than the center of the spinous process and are less susceptible to inadvertent off-axis imaging.

To compare clinical effect and safety between posterior fossa decompression with duraplasty (PFDD) and posterior fossa decompression without duraplasty (PFD) in treatment of Chiari type I malformation and basilar impression. ⋯ PFD is a more efficient and safer therapy than PFDD in the treatment of Chiari type I malformation with basilar impression.

The objective of the study was to compare the safety, efficacy, and accuracy of the pedicle screws with the three-dimensional (3D) printed navigation template to the free-hand screws for type II odontoid fractures. ⋯ The herein screw technique using 3D printed navigation template leads to greater improvement in the screw safety, efficacy, and accuracy, which may be a promising alternative to free-hand surgery for the treatment of odontoid fractures.

Cervical radiculopathy is a common disabling cervical spine condition. Open anterior and posterior approaches are the conventional surgical treatment approaches with good clinical outcomes. However, the soft tissue damage in these procedures can lead to increase perioperative morbidity. Endoscopic spine surgery provides more soft tissue preservation than conventional approaches. We investigate the radiological and clinical outcomes of posterior endoscopic cervical foraminotomy and discectomy. ⋯ Uniportal posterior endoscopic cervical foraminotomy and discectomy are safe, efficient and precise choreographed set of technique in the treatment of cervical radiculopathy. It significantly improved clinical outcomes and achieved the objective of increasing in the cervical foramen size in our cohort of patients.

To understand the anatomical relationship between the cervical sympathetic trunk (CST) and the cervical fascia and to provide a more reliable method for avoiding CST injury during the anterolateral cervical spine surgical approach. ⋯ The CST was tightly adhered to the alar fascia and could be naturally retracted with the alar fascia. Retracting the alar fascia can effectively protect the CST.
