To verify the feasibility and discuss advantages and disadvantages of a piezoelectric orbitotomy during superior eyelid endoscopic transorbital approach (SETOA). An illustrative case demonstrating the application of this novel technique is also presented. ⋯ Piezoelectric orbitotomy may offer a viable, selective, effective, safe alternative to high-speed drilling during SETOA, especially for patients with intra-axial pathologies, in which a watertight closure is mandatory. This procedure could prevent or decrease the risk of some of the main postoperative complications associated with standard SETOA, potentially resulting in better functional and esthetic outcomes.

Spinal injuries occur in 3% of all patients with trauma, most commonly in males, and often as a result of high-velocity impact followed by abrupt deceleration. The most affected region after spinal trauma is the thoracolumbar junction because of the anterior center of gravity at the T12-L1 vertebral level and the relatively stiff thoracic spine uniting with the mobile lumbar spine. Many classifications exist to guide the choice of operative versus nonoperative management of traumatic injuries at this site. ⋯ Ignoring this aspect of thoracolumbar management often contributes to the development of posttraumatic malalignment and other complications. This review recommends that a new or modified classification system accounts for sagittal segmental alignment factors, including the level of the injured vertebra, the number of affected adjacent levels, imaging techniques with better specificity and sensitivity, and assessment for osteoporosis. Case studies are included to show the importance of segmental sagittal alignment and the vertebral level on patient outcomes.

Disparities in access and delivery of care have been shown to disproportionately affect certain racial groups. Studies have been conducted to assess these disparities within the spinal metastasis population, but the extent of their effects in the setting of other socioeconomic measures remains unclear. The purpose of this study was to perform a systematic review to understand the effect of racial disparities on outcomes in patients with metastatic spine disease. ⋯ Although some studies suggest race to be associated with presenting characteristics, treatment type and outcome of patients with spinal metastases, there was significant variability in the inclusion of measures of socioeconomic status in study analyses. As such, the association between race and outcomes in oncologic spine surgery remains unclear.

To evaluate the efficacy of hemilaminectomy as an approach to intradural tumors and to assess the risk of postoperative spinal instability. ⋯ Unilateral hemilaminectomy is an effective technique that facilitates complete tumor removal with a low rate of postoperative instability in the operated segments.
