Vertebral End Plate Perforation for Intervertebral Disc Height Preservation After Single Level Lumbar Discectomy: A Randomized Controlled Trial.
Pilot single-centre, stratified, prospective, randomized, double-blinded, parallel-group, controlled study. ⋯ The present study showed positive correlation between the volume of removed disc tissue and decrease in postoperative ISV and ISH. There were no statistically significant differences in ISV and ISH between the group with end-plate perforation and the control group six months after lumbar discectomy. Clinical outcome and disability were significantly improved in both groups three and six months after surgery.

Does the position of the aorta change with the altered body position in Ankylosing Spondylitis patients with thoracolumbar kyphosis?-A Magnetic Resonance Imaging Investigation.
A prospective magnetic resonance imaging (MRI) study. ⋯ There is no significant change of the relative positions between the aorta and the vertebrae at T9-L3 levels after the patient turned to a prone position, which implied that the mobility and range of motion of the aorta is limited in advanced stage of AS.

Comparative StudyZero-profile Anchored Spacer Reduces Rate of Dysphagia Compared With ACDF With Anterior Plating.
Retrospective cohort study. ⋯ Zero-profile anchored spacers lead to similar clinical and radiographic outcomes compared with ACDF with plating and may carry a lower risk of postoperative dysphagia.

Comparative StudyComparison of navigated versus non-navigated pedicle screw placement in 260 patients and 1434 screws: screw accuracy, screw size, and the complexity of surgery.
Computer 3D navigation (3D NAV) techniques in spinal instrumentation can theoretically improve screw placement accuracy and reduce injury to critical neurovascular structures, especially in complex cases. In this series, we analyze the results of 3D NAV in pedicle screw placement accuracy, screw outer diameter, and case complexity in comparison with screws placed with conventional lateral fluoroscopy. ⋯ The use of 3D NAV was associated with improved screw placement accuracy, improved screw-to-pedicle diameter measurements, and was used in cases with a higher degree of surgical complexity. We conclude that 3D NAV is a valuable tool in current spinal instrumentation, especially for more complex surgeries.
