Radiographic predictors of residual low back pain after laminectomy for lumbar spinal canal stenosis: minimum 5-year follow-up.
Retrospective study of patients who underwent laminectomy for unification. ⋯ Our results indicate that preoperative lordosis angle and lumbar ROM were the significant radiographic predictors for residual LBP after laminectomy for LCS. Patient with flatback and limited lumbar mobility before surgery are prone to suffer residual LBP. It is suggested that these sagittal radiographic parameters should be taken into account when choosing laminectomy as the surgical option for LCS.

Randomized Controlled TrialPosition of interbody spacer in transforaminal lumbar interbody fusion: effect on 3-dimensional stability and sagittal lumbar contour.
Biomechanical study. ⋯ Difference in ROM and NZ between anterior (TLIF-A) or posterior (TLIF-P) positions was not statistically significant. Similarly, both positions did not influence segmental lordosis.

Case ReportsCervical myelopathy caused by pseudoarthrosis between posterior arch of the atlas and lamina of the axis in Klippel-Feil syndrome: a case report.
Case report. ⋯ Coincidence of several bony anomalies such as assimilation of C2 and C3, which were fused in hyperlordosis, and the bipartition of the atlas may biomechanically influence the formation of pseudoarthrosis between the posterior arch of the atlas and the lamina of the axis. Because symptoms appeared in the patient's 60s despite congenital bony anomaly, degeneration might contribute to the formation of massive osteophytes. Posterior decompression was effective in this case.

Long-term biomechanical stability and clinical improvement after extended multilevel corpectomy and circumferential reconstruction of the cervical spine using titanium mesh cages.
Retrospective review of clinical case series. ⋯ Circumferential reconstruction using titanium mesh cages after EACC can provide appropriate, biomechanically stable fixation and allows for significant correction of preexisting kyphosis. Supplemental posterior instrumentation may limit delayed cage subsidence and loss of sagittal balance after this procedure. EACC and circumferential reconstruction seems to be an effective treatment for symptomatic degenerative, traumatic, or infectious pathology involving 3 or more levels of the anterior cervical spine.
