To evaluate the association between postoperative lumbar curve progression and the shoulder height in patients with Lenke type 2B/C adolescent idiopathic scoliosis (AIS). ⋯ Postoperative lumbar curve progression is a risk factor for deterioration of shoulder imbalance in patients with Lenke 2B/C AIS during the follow-up period.

The number of endovascular treatment procedures performed for cerebral aneurysms has markedly increased. However, little is known about the annual effective radiation dose to medical staff in neurointervention fields. We performed a retrospective observational study to investigate the real-time radiation dose to surgeons, nurses, anesthesiologists, and radiologic technologists during endovascular treatment of intracranial aneurysms. ⋯ We confirmed the differences in the amount of radiation exposure for different roles. An additional lead screen, which provided more effective protection on the operator side, was proved effective for attenuating radiation exposure during endovascular treatment. All personnel involved in the hybrid operating room were exposed to acceptable effective doses.

Presacral schwannomas are rare benign tumors that may reach large size before becoming symptomatic. Total surgical removal has been considered the best treatment option. Tumors arising from the presacral area are commonly managed through anterior approaches, whereas posterior approaches are used for pure intrasacral tumors or large lesions with both intra and presacral extension, alone or in combination with anterior approaches. ⋯ The posterolateral trans-sacral ala approach may represent a minimally invasive option in the surgical management of presacral well-circumscribed benign tumors. Spinal navigation could be properly used to facilitate lesion exposure, and to minimize the bone removal. The intraoperative neurophysiological monitoring is an essential tool for the preservation of the lumbosacral nerve roots.

We report a retrospective analysis of hardware failure in patients requiring instrumentation for spinal metastasis. ⋯ The rate of hardware failure in this cohort was 13.8%, although operative revision rate was 3.4%. Spinal instrumentation in patients with poor preoperative functional status or multiple myeloma may be more likely to develop instrumentation failure.

To compare the results of full-endoscopic decompression (FED) in lumbar lateral recess stenosis via an interlaminar or transforaminal approach. ⋯ FED could provide satisfactory clinical outcomes for lumbar lateral recess stenosis. However, the IL-FED procedure demonstrated shorter operation time and lesser radiation exposure, but higher risk for anesthetic when compared with the TF-FED procedure.
