Case Reports
Posterolateral cervical transpedicular corpectomy for the surgical management of metastatic tumor.
Management of metastatic spinal disease in the upper cervical spine can be particularly challenging. Depending on the level of the lesion and the patient's anatomy, multiple anterior approaches have been described for resection of the cancer, followed by posterior fixation and instrumentation. Although a single-stage posterolateral approach is now well established for thoracic pathology, less is known about the applicability of these principles when applied as an approach to the cervical spine. The authors present here a case using a posterolateral transpedicular approach for corpectomy and graft placement for circumferential reconstruction as a treatment of metastatic disease in the cervical spine to illustrate the feasibility of this technique, especially in the setting where the patient's anatomy or pathology may impede an anterior or combined circumferential approach.

Review Meta Analysis
Robot-assisted and conventional freehand pedicle screw placement: a systematic review and meta-analysis of randomized controlled trials.
Several studies have revealed that robot-assisted technique might improve the pedicle screw insertion accuracy, but owing to the limited sample sizes in the individual study reported up to now, whether or not robot-assisted technique is superior to conventional freehand technique is indefinite. Thus, we performed this systematic review and meta-analysis based on randomized controlled trials to assess which approach is better. ⋯ The robot-assisted technique was associated with equivalent accuracy rate of pedicle screw implantation, fewer proximal facet joint violation, less intraoperative radiation exposure but longer surgical duration than freehand technique. Powerful evidence relies on more randomized controlled trials with high quality and larger sample size in the future.

Review Case Reports
Surgical complications of extraspinal tumors in the cervical spine: a report of 110 cases and literature review.
To assess the safety of surgical intervention for extraspinal tumors in the cervical spine. ⋯ Surgery for cervical spine tumor could improve the quality of life, though it might be accompanied with high morbidity and mortality. It is a highly demanding procedure; however, it can be performed to an acceptable degree of safety.
