Comparative StudySagittal alignment after lumbar interbody fusion: comparing anterior, lateral, and transforaminal approaches.
Retrospective radiographic analysis. ⋯ After lumbar interbody fusion, improvement of lordosis was significant for both the anterior and lateral groups, but not the transforaminal group. Intergroup analysis showed the anterior group had significantly improved lordosis compared to both the other groups. The anterior and lateral groups had significantly increased disk height compared to the transforaminal group. All the 3 groups significantly reduced spondylolisthesis, with no difference between the groups.

Risk factors for L5-S1 disk height reduction after lumbar posterolateral floating fusion surgery.
This is a retrospective study. ⋯ In posterolateral floating fusion surgery, there was a higher risk of L5-S1 disk height reduction and consequent foraminal stenosis in patients with multiple-level fusion. Surgical methods and fusion levels should be chosen after considering their association with L5-S1 disk height reduction.

Review Meta Analysis Comparative StudyLumbar fusion versus nonoperative management for treatment of discogenic low back pain: a systematic review and meta-analysis of randomized controlled trials.
Systematic review and meta-analysis of randomized controlled trials (RCTs). ⋯ Despite the significant improvement in ODI in the lumbar fusion groups in 3 studies, pooled data revealed no significant difference when compared with the nonoperative group. Although there was an overall improvement of 7.39 points in the ODI in favor of lumbar fusion, it is unclear that this change in ODI would lead to a clinically significant difference. Prospective randomized trials comparing a specific surgical technique versus a structured physical therapy program may improve evidence quality. Until then, either operative intervention by lumbar fusion or nonoperative management and physical therapy remain 2 acceptable treatment methods for intractable low back pain.

Comparative StudyEffective cervical decompression by the posterior cervical foraminotomy without discectomy.
A retrospective review. ⋯ Despite the surgical and anatomic limitations, PCF with or without discectomy is an effective treatment for cervical disk herniation.

Influence of prone positioning on potential risk of aorta injury from pedicle screw misplacement in adolescent idiopathic scoliosis patients.
A prospective magnetic resonance imaging (MRI) study. ⋯ Prone positioning may increase the potential risk of aorta injury in RT-AIS patients, particularly at T5-T6 and T11 even if a left TPS just barely touches the anteriolateral or lateral cortex of the vertebrae. Laterally misplaced TPSs should be removed at these high aorta-at-risk levels.
