This study aimed to evaluate the clinical and radiological effects of indirect decompression after anterior lumbar interbody fusion for central spinal canal stenosis. The authors believe that their study makes a significant contribution to the literature because it reports on the effects of indirect decompression of central canal stenosis performed using anterior lumbar interbody fusion, which has been less studied, and this is also the first quantitative analysis of indirect decompression after anterior lumbar interbody fusion for central spinal canal stenosis.

This article assesses the long-term predictive capability of the SAFIRE grading scale using the Barrow Ruptured Aneurysm Trial (BRAT) patient population by comparing patient outcomes at the 1- and 6-year follow-ups. The SAFIRE grading scale is a simple bedside assessment that predicts the prognostic outcome of aSAH patients at 2 months. Furthermore, this study finds that the grading scale may also be used as a predictor of long-term outcomes in these patients.

The authors compared standing and supine radiographs for 73 patients and found that those with bilateral sacroiliac (SI) joint vacuum signs, as identified on CT, had a change in pelvic incidence between the supine and standing positions. This suggests there may be increasing motion across the SI joint with significant joint degeneration.

The object of this study was to evaluate the utility of proton density–weighted MRI and tractography of the intersecting dentato-rubro-thalamic tract for direct "intersectional" targeting of the ventral intermediate nucleus for treating patients with essential tremor (ET). This method was feasible for deep brain stimulation lead placement in patients with ET. These advanced targeting techniques can supplement awake intraoperative testing or be used independently in asleep cases to improve surgical efficiency and confidence.

The objective of this paper was to evaluate the clinical and hemodynamic benefits of an occipital artery–middle cerebral artery bypass for patients with pediatric moyamoya disease who had recurrent symptoms after initial revascularization. Cerebrovascular reactivity values in both middle cerebral artery and posterior cerebral artery territories are significantly improved, with clinical improvement after occipital artery–middle cerebral artery bypass despite progression of posterior cerebral artery stenosis in most patients. The occipital artery–middle cerebral artery bypass is an effective rescue therapy for cases of pediatric moyamoya disease.
