The authors sought to evaluate the efficacy of hemispherectomy in pediatric epilepsy at their center and determine whether contralateral MRI abnormalities can predict seizure recurrence. This study is important as it will help guide surgical decision-making in children with intractable epilepsy.

To determine if subarachnoid space loss is associated with syrinx formation and if syrinx resolution is associated with the expansion of subarachnoid spaces after surgery, the authors performed a retrospective review of patients at their institution who underwent posterior fossa decompression for Chiari malformation type I (CM-I). The study results demonstrate that CM-I patients with a syrinx have significantly decreased patency of subarachnoid spaces compared with patients without a syrinx and that restoration of subarachnoid patency is associated with syrinx resolution.

In this study, the authors analyzed current age- and sex-specific aneurysmal subarachnoid hemorrhage (aSAH) incidence rates and 30-day case-fatality rates. The incidence of aSAH over 20 years in Olmsted County, Minnesota, was examined and compared to a previous analog study made in the same population. The results were also compared with regional trends in smoking habits. This study aims to show that both aSAH incidence and case-fatality rates have significantly decreased over time.

Currently, there is no clear answer of when to divert CSF in patients with posterior fossa tumors (PFTs). The ideal surgical option is also debatable. The protocol at the authors’ institution had been to perform endoscopic third ventriculostomy (ETV) before PFT resection as a temporizing measure if needed. They used the modified Canadian Preoperative Prediction Rule for Hydrocephalus (mCPPRH) retrospectively to determine which PFTs were at high risk of requiring CSF diversion. Until now, no study analyzed the role of ETV in children with high mCPPRH scores. Based on the findings from this study, the authors will change their practice.

The authors analyzed the impact of the L4–5 prosthetic positioning on functional results, which has not been done before. The prosthetic positioning can be chosen during surgery with the aid of fluoroscopic control. If a certain position provides better outcomes, the surgical technique can be improved to always reproduce the same accurate prosthetic positioning.
MIS lateral ACR for spinal deformity correction: technique and complication avoidance
Deformity correction using minimally invasive surgical (MIS) techniques can be challenging. Here the authors present a case in which an anterior column resection was performed using an MIS lateral approach to restore lumbar lordosis and improve sagittal balance. The authors demonstrate the technique and discuss potential complications and how they may be avoided.
