To revalidate the craniometric dimensions of classic posterior burr holes for ventricular catheter insertion in hydrocephalic patients, based on ideal catheter position on a 3-dimensional simulated computed tomography (CT) reconstruction model of the ventricles. ⋯ The use of a suggested burr hole point for posterior ventricular catheterization may decrease the amount of parenchymal mantle of the brain transgressed by the catheter, and may marginally improve the chance of successful posterior ventricular catheterization.

Comparative Study
Multilevel Posterior Column Osteotomies Are Not Inferior For the Correction of Rigid Adult Spinal Deformity Comparing to Pedicle Subtraction Osteotomy.
Posterior column osteotomy (PCO) has been used for the correction of various spinal deformities. However, little evidence is available regarding the effects of multilevel PCO in adult spinal deformity (ASD) surgery. This study aimed to show the usefulness of PCO in rigid ASD surgery by assessing radiographic and clinical outcomes. We also aimed to assess the corrective potential of multilevel PCOs compared with a single-level pedicle subtraction osteotomy (PSO). ⋯ Multilevel PCOs for the correction of rigid ASD were slightly superior to PSO, regarding clinical outcomes. Radiographic outcomes were similar between groups. Thus, multilevel PCOs may be a viable option for the treatment of rigid ASD with a mobile segment.

Although not life threatening, hemifacial spasm (HFS) can be disabling and significantly affect quality of life (QOL). The aim of this study was to assess the major factors affecting the QOL and further to investigate the impact of microvascular decompression (MVD) on QOL in patients with HFS. ⋯ HFS affects QOL both physically and mentally. Patients with severe HFS symptoms or a higher educational level are at higher risk of worse QOL. MVD not only provides high spasm-relief rate but also leads to significantly higher QOL after surgery.

Cervical and thoracic tandem spinal stenosis (ct-TSS) is a rare yet challenging degenerative disease. When the diagnosis is made, surgical decompression is indicated for both lesions. However, literature about the surgical approaches and prognosis of this disease is lacking. ⋯ The types of stenotic lesions should be considered when planning surgery for patients with ct-TSS. One-stage decompression is suitable for patients with adjacent stenotic lesions; staged procedures should be considered for other patients.

Observational Study
Influence of obesity on complications, clinical outcome and subsidence following anterior lumbar interbody fusion (ALIF): prospective observational study.
The complications associated with obesity have been well described for posterior lumbar spinal surgery. However, the influence of obesity on anterior lumbar interbody fusion (ALIF) is not well established. We aimed to compare complication risks, functional outcomes, and subsidence rates in normal-weight, overweight, and obese patients who underwent ALIF. ⋯ There were no differences in functional outcomes or complications in patients with elevated BMI compared with normal-weight patients. Fusion rates were lower for patients were obese. Obesity should not be considered a contraindication to surgery in patients with appropriate indication to undergo ALIF.
