The middle meningeal artery (MMA) is a major dural vessel that plays a significant role in developing chronic subdural hematomas (cSDHs). Understanding its variable anatomy is essential for the effective management of cSDH and the prevention of complications. ⋯ The most common configuration of MMA was Adachi-type IC. The MMA most often originated from the maxillary artery. The posterior branch of the MMA was typically dominant and most frequently originated from the distal segment. There was no significant impact of Adachi type on treatment results or fluoroscopy time.

The subsidence of vertebral body replacement may occur after anterior cervical corpectomy and fusion (ACCF) , which may lead to cervical kyphosis, spinal cord compression and neurological dysfunction. The authors aim to investigate the risk factors for early subsidence of 3D printed artificial vertebral (3D-PAVB) after ACCF surgery and to provide guidance for clinical practice. ⋯ The occurrence of early subsidence of 3D-PAVB post ACCF surgery is influenced by two independent risk factors - smoking and low HU. To predict the likelihood of this outcome, it is advisable to consider smoking history and measure CT HU value prior to surgery. A lower CT HU value is indicative of a greater risk of subsidence.

The most widely adopted materials for interbody fusion implants are titanium and polyetheretherketone (PEEK), both of which have potential advantages and disadvantages. Despite the differences between PEEK and titanium, there is no consensus on which material provides better clinical and radiological outcomes. Therefore, the purpose of this meta-analysis was to analyze the clinical and radiographic outcomes between the 2 cages. ⋯ In the lumbar spine, titanium cages were shown to have a lower rate of subsidence and revision compared with PEEK cages. In the cervical spine, the difference between cages did not reach statistical significance in any of the analyzed outcomes.

Postoperative pain is the most common undesirable outcome after neurosurgery. Ketorolac is a non-steroidal anti-inflammatory drug (NSAID) which is administered parenterally and carries a theoretical increased risk of bleeding. Our study aims to determine whether ketorolac after craniotomy for tumor resection significantly changes the rate of postoperative adverse events, adequately controls pain, and decreases concurrent narcotic usage. ⋯ Ketorolac is a safe and effective option for pain control after craniotomy for tumor resection. Prospective data is needed to better validate these retrospective observations.
