Clinical TrialProspective Study of Posterior Lumbar Interbody Fusion With Either Interbody Graft or Interbody Cage in the Treatment of Degenerative Spondylolisthesis.
A prospective study of 2 different fusion techniques for the treatment of single-level degenerative spondylolisthesis. ⋯ We have found the use of a cage to achieve lumbar interbody fusion in the treatment of degenerative lumbar spondylolisthesis does not confer any significant advantages in terms of restoration of lumbar lordosis, improvement in clinical symptoms, or relief of pain postoperatively.

Review Meta Analysis Comparative StudyComparison of Anterior Decompression and Fusion With Posterior Laminoplasty for Multilevel Cervical Compressive Myelopathy: A Systematic Review and Meta-Analysis.
Systematic review and meta-analysis. ⋯ On the basis of this meta-analysis, anterior decompression and fusion is associated with better recovery of neurological function, better postoperative cervical alignment, higher postoperative complication and reoperation rates, more blood loss, and longer operative times compared with posterior laminoplasty.

Does Navigation Improve Accuracy of Placement of Pedicle Screws in Single-level Lumbar Degenerative Spondylolisthesis?: A Comparison Between Free-hand and Three-dimensional O-Arm Navigation Techniques.
This was a prospective, nonrandomized study. ⋯ O-arm navigation does not provide any significant advantage over conventional free-hand pedicle screw insertion technique in patients with single-level degenerative spondylolisthesis. The accuracy is dependent on the distance of the tracker from the level of instrumentation. Lateral perforations are more common because of instability at the instrumented level leading to translation and rotation of the vertebral body while placing pedicle screws leading to preferential lateral trajectory. These lateral perforations could not be prevented by using navigation. However, no significant complications were noted in either technique.

Comparative StudyDo Intraoperative LIV-Tilt and Disk Angle Remain Stable at 2-year Follow-up Compared With Upright Radiographs in Patients With Idiopathic Scoliosis?: A Retrospective Cohort Study.
This study was a retrospective chart and radiographic review. ⋯ Compared with prone intraoperative fluoroscopic images, disk wedging below LIV remains stable at 2 years postsurgery on standing radiographs in patients with AISundergoing PSF, including structural lumbar curves, whereas LIV-tilt improvement is not maintained. Intraoperative fluoroscopy provides a reliable prediction of disk wedging below LIV, 2 years after surgery on standing radiographs.

Predictors of Motor Weakness and Delayed Recovery in Cervical Disk Herniation.
Retrospective study. ⋯ Decreased disk height, percentage of HNP in the spinal canal, or presence of signal intensity change in the spinal cord seem to be the important risk factors for motor weakness in patients with cervical disk herniation. Moreover, the presence of signal intensity change in the spinal cord seems to be an important risk factor for delayed recovery.
