Comparative StudyComparison and correlation of pelvic parameters between low-grade and high-grade spondylolisthesis.
This study was retrospectively conducted on 51 patients with L5-S1 spondylolisthesis. ⋯ A significant difference in the lumbosacral angle, slip angle, L5 incidence, PI, L5 slope, sacral inclination, and PT was shown between the patients with high-grade spondylolisthesis and patients with low-grade spondylolisthesis. Among the aforementioned measurements, the PI showed a significant difference between the 2 groups and also had a significant correlation with the dislocation level in all the patients.

Comparative StudyRelative benefit of TLIF versus PSF stratified by diagnostic indication.
Case-matched retrospective. ⋯ Clinical outcome was not significantly altered with TLIF as compared with PSF in patients with spondylolisthesis or disk pathology. However, TLIF resulted in better outcomes at 2 years postoperatively in patients with postdecompression instability.

Case ReportsRadiologic evaluation after posterior instrumented surgery for thoracic ossification of the posterior longitudinal ligament: union between rostral and caudal ossifications.
Retrospective clinical study. ⋯ All patients needing surgery had discontinuity across the disk space between the rostral and caudal ossified lesions as seen on CT. This discontinuity was considered to be the main reason for the myelopathy because a high-intensity area on magnetic resonance imaging was seen in 18 of 19 patients at the same level. Rigid fixation with instrumentation may allow the discontinuous segments to connect in patients without a concomitant thickening of the OPLL.

Analysis of sagittal balance of ankylosing spondylitis using spinopelvic parameters.
Prospective study. ⋯ AS patients and normal controls were found to be significantly different in terms of sagittal spinopelvic parameters. Significant relationships were found between sagittal spinopelvic parameters in AS patients. Pelvic tilt was a significant parameter in determination of sagittal balance in AS patient. Furthermore, VAS scores were significantly related to sagittal spinal parameters which were closely related with pelvic orientation in AS patients.

Surgical treatment of scoliosis in osteogenesis imperfecta with cement-augmented pedicle screw instrumentation.
A retrospective study. ⋯ Pedicle screw instrumentation in OI scoliosis is safe and effective. Cement augmentation in these patients may help to increase the pedicle pull-out strength and decrease the screw failure rates, especially at the proximal and the distal ends of instrumentation.
