Multilevel lumbar spinal stenosis decompression: midterm outcome using a modified hinge osteotomy technique.
A prospective cohort study was carried out looking at the functional outcome and post procedure translational segmental instability after multi-level lumbar decompression using a hinge osteotomy technique. ⋯ Decompression of multi-level lumbar spine stenosis using the unilateral approach with the hinge osteotomy technique is a safe approach for multi-level stenosis, with good outcome and no evidence of significant segmental translational spinal instability.

Case ReportsSafety and efficacy of concurrent pediatric spinal cord untethering and deformity correction.
A retrospective clinical records analysis of concurrent pediatric spinal cord deformity correction and tethered cord release compared with a 2-staged approach. ⋯ Concurrent tethered cord release and spinal fusion for correction of scoliosis and/or kyphosis may be a safe and effective approach in patients likely to experience deformity progression.

Which is the preferred revision technique for loosened iliac screw? A novel technique of boring cement injection from the outer cortical shell.
An in vitro biomechanical cadaver study. ⋯ Wadding corticocancellous bone and increasing screw length failed to provide sufficient anchoring strength for a loosened iliac screw; however, both traditional and boring PMMA-augmented techniques could effectively increase the fixation strength. On the basis of the viewpoint of minimal invasion, the boring PMMA augmentation may serve as a suitable salvage technique for iliac screw loosening.

Lateral transpsoas interbody fusion (LTIF) with plate fixation and unilateral pedicle screws: a preliminary report.
Retrospective cohort study. ⋯ We report a series of patients treated with unilateral pedicle screw fixation with LTIF. Although the patient cohort is small, validated outcomes instruments were used and fusion was assessed by computed tomography scan in most cases. The data suggest that unilateral pedicle screw fixation may be adequate to achieve high fusion rates after LTIF surgery using anterior instrumentation. Applying this technique in patients with osteoporosis may lead to a significant risk of postoperative vertebral body fracture.
