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.

Extreme lateral interbody fusion approach for isolated thoracic and thoracolumbar spine diseases: initial clinical experience and early outcomes.
Retrospective review of prospective collected data on 22 patients. ⋯ The XLIF technique can be expanded to treat diseases in the thoracic spine. Although the magnitude of deformity correction achieved is less than that of the traditional open approaches, the lesser invasiveness of this technique may be tolerable for the elderly and in patients with significant medical comorbidities.

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.

Migration of thoracic aorta after the anterior correction of thoracic idiopathic scoliosis without parietal pleura closure.
To compare the preoperative and postoperative relative position of the thoracic aorta to the vertebrae in patients with idiopathic scoliosis (IS) after anterior corrective surgery without parietal pleura closure. ⋯ The thoracic aorta in patients with predominant right thoracic IS migrated posterolaterally relative to the vertebral body after anterior surgery without parietal pleura closure.

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.
