The lumbar neural foraminal stenosis still is a challenging condition in minimally invasive spine surgery. Because of the anatomic situation a complete decompression of the nerve root often leads to a subtotal facetectomy associated with potential instability and the need for additional instrumentation of the decompressed segment. The iO-Flex system was introduced to address this problem by using a minimally invasive wire-guided microblade shaver to increase the neuroforaminal space by reducing the stenosis from intraforaminal while sparing bigger parts of the facet joint. In this study, we evaluated the feasibility and the surgical and radiological success in relation to the experience of the surgeon. ⋯ The flexible micro blade shaver system is feasible with a steep learning curve and achieves sufficient decompression of the neuroforamen in this cadaveric study.

Cavernous sinus hemangioma (CSH) is a rare type of benign vascular tumor. Microsurgery for CSH treatment usually results in profuse bleeding and cranial nerve injury. Radiosurgery is an alternative treatment for CSH. The objective of this study was to elucidate the efficacy and safety of gamma knife surgery (GKS) for the treatment of CSH. ⋯ GKS is a safe and effective treatment for most cases of CSH. The concept of GKS as an adjuvant treatment for CSH requires reconsideration.

Epidemiologic studies show that an increasing proportion of those presenting with head trauma are elderly. This study details the outcomes of elderly patients with head trauma admitted to a regional United Kingdom neurosurgical unit. ⋯ Most elderly patients admitted under neurosurgery after head injury have SDHs. Our results are better than many previously reported; however, the rate of death for those with ASDH is still high.
