The pedicle-facet angle and tropism in the sagittal plane in degenerative spondylolisthesis: a computed tomography study using multiplanar reformations techniques.
A case-control study. ⋯ The P-F angle was the highest at L4-L5 both in the DS and the control group, which might explain the fact that L4 vertebra is more likely to slip forward. The P-F angle of the slipped vertebra alone was more horizontally inclined and facet tropism in the sagittal plane may relate well to DS.

The influence of thoracic inlet alignment on the craniocervical sagittal balance in asymptomatic adults.
A prospective radiographic study. ⋯ The thoracic inlet alignment had significant correlations with craniocervical sagittal balance. To preserve physiological NT around 44 degrees, large TIA increased T1 slope and CL and vice versa. TIA and T1 slope could be used as parameters to predict physiological alignment of the cervical spine. The results of this study may serve as baseline data for the evaluation of sagittal balance or planning of a fusion angle in the cervical spine.

Comparative StudyComparing vertebral body reconstruction implants for the treatment of thoracic and lumbar metastatic spinal tumors: a consecutive case series of 37 patients.
Retrospective case series. ⋯ Vertebral body reconstruction after corpectomy for patients with metastatic tumors to the thoracic and lumbar spine can be performed effectively with metal, bone, or cement implants. Although metal implants are used in the majority of reconstruction cases, they seem to have a higher rate of overall complications, with bone interbody constructs showing a higher rate of revision surgery.

Axial presacral lumbar interbody fusion and percutaneous posterior fixation for stabilization of lumbosacral isthmic spondylolisthesis.
Case series. ⋯ The minimally invasive presacral axial interbody fusion and posterior instrumentation technique is a safe and effective treatment for low-grade isthmic spondylolisthesis.

Investigation of segmental motor paralysis after cervical laminoplasty using intraoperative spinal cord monitoring with transcranial electric motor-evoked potentials.
A retrospective study of segmental motor paralysis after cervical laminoplasty for cervical myelopathy. ⋯ There were no abnormal findings on transcranial electric motor-evoked potential monitoring even in those patients who developed postoperative C5 palsy. These results indicate that the development of postoperative segmental motor paralysis after cervical laminoplasty occurs even if there are no abnormal findings during intraoperative monitoring.
