To determine whether preoperative presence of degenerative lumbar spondylolisthesis (DS) worsens the minimum 10-year outcome of patients undergoing microendoscopic decompression (MED) for lumbar spinal stenosis (SS). ⋯ Our study indicated that preoperative DS did not worsen the outcome of patients with SS undergoing MED.

To understand how physicians in the United States manage patients with small unruptured intracranial aneurysms and factors that influence the management. ⋯ For aneurysms 2-4 mm, majority of the physicians preferred regular follow-up, whereas for aneurysms 5-7 mm, the majority favor treatment. There remains heterogeneity in practice among physicians in the United States regarding follow-up strategies for small unruptured aneurysms. Further studies are needed to evaluate the optimal management strategy, follow-up frequency and duration of imaging for small unruptured intracranial aneurysms.

The aim of this study is to determine if frailty, defined as modified frailty index (MFI) >2.7, correlated with worse postoperative outcomes in patients with chronic subdural hematomas (CSDHs). We also compare the predictive ability of the MFI with another widely used frailty measure, the Clinical Frailty Scale (CFS). ⋯ Elderly patients presenting with CSDH who are frail (MFI >0.27) have significantly worse functional outcomes following twist-drill craniostomies. Therefore assessing frailty in this population is important before managing these patients, and for this purpose the CFS is a superior predictor of postoperative function than the MFI.

The treatment of unilateral CFD in patients without neurologic deficits remains controversial, especially in the choice of the best surgical approach. Our objective is to determine the way spine surgeons from Latin America manage this condition. ⋯ Wide variations exist in the management of unilateral CFD by Latin American surgeons, with early injuries generally treated using either an anterior or posterior approach and treated early but after an MRI, while a combined approach is used more commonly with late injuries. Either an anterior or combined approach is used when disk herniation is present.

Cavernous sinus hemangiomas (CSHs) are extraaxial vascular malformations that tend to bleed during surgery. ⋯ A combination of low signal on T1, high signal on T2 and fluid-attenuated inversion recovery, no diffusion restriction and homogenous enhancement should place CSH at the top of the list of differential diagnoses. This is especially true when there is a "filling-in" pattern on dynamic or delayed imaging. Doing so may alert surgeons to the possibility of copious intraoperative bleeding and therefore avoid complications of hemorrhage.
