Epiduroscopy is a type of spinal intervention that visualizes the epidural space through the sacral hiatus using a fiberoptic scope. However, it is technically difficult to perform compared to conventional interventions and susceptible to complications. Surgery simulator has been shown to be a promising modality for medical education. ⋯ The realism of the epidural simulator was evaluated to be acceptable in 40%. Participants improved their simulator skills through repeated attempts. The epiduroscopy simulator helped participants understand the anatomical structure and actual epiduroscopy.

Fluoroscopy-Guided Blockade of the Greater Occipital Nerve in Cadavers: A Comparison of Spread and Nerve Involvement for Different Injectate Volumes.
Fluoroscopy-guided blockade of the greater occipital nerve (GON) is an accepted method for treating the symptoms of cervicogenic headaches (CGHs). However, the spread patterns among different injectate volumes of fluoroscopy-guided GON blocks are not well defined. ⋯ A 3.5 or 5 mL fluoroscopy-guided GON injection of methylene blue successfully stains the GON, TON, and suboccipital nerves. This suggests that such an injection would generate blockade of all three nerve groups, which may contribute to the efficacy of the block for CGH. A volume of 3.5 ml may be enough for the performance of a fluoroscopy-guided GON block for therapeutic purposes.

Clinical and radiological data of 204 patients were reviewed. The patients were divided into Group A (PVP alone) and Group B (PVP and FB combined therapy) according to treatments. Back pain was evaluated with Visual Analog Scale (VAS) and Oswestry Disability Index (ODI). The operation, fluoroscopic exposure time, and bone cement leakage were recorded. The χ2 test, Student's t-test, and repeated measures analysis of variance were used to compare the differences between the two groups. ⋯ PVP and FB combined therapy could provide better pain relief than PVP alone in short term after operation in patients with OVCFs associated back pains.

We aimed to present our experience in anchoring technique and evaluate the efficacy and safety of unilateral percutaneous vertebroplasty in patients with neurologically intact Kümmell's disease. ⋯ We considered that the anchoring technique in unilateral PVP could provide an effective and safe alternative for neurologically intact Kümmell's disease.
