External ventricular drain (EVD) placement is a life-saving procedure performed frequently by neurosurgical residents. The July effect is a theoretic decline in quality of health care sometimes perceived in teaching hospitals at the start of an academic year. We sought to quantify the learning curve of ventriculostomy drain placement in teaching hospitals and determine its impact on patient outcomes, health care utilization, and cost. ⋯ There was no evidence of a July effect on EVD complication rates in outcomes for patients admitted in the beginning of an academic year versus the end.

There is still debate in the literature on the existence of the arcade of Struthers and moreover the potential role of this structure to cause compression of the ulnar nerve. ⋯ This case demonstrates that a muscular arcade of Struthers can cause symptoms of ulnar neuropathy. Ultrasound in this case proved to be helpful in the preoperative workup, clearly demonstrating this unusual site of compression.

Minimally invasive spine surgery (MISS) has continued to evolve over the past few decades, with significant advancements in technology and technical skills. From endonasal cervical approaches to extreme lateral lumbar interbody fusions, MISS has showcased its usefulness across all practice areas of the spine, with unique points of access to avoid pertinent neurovascular structures. ⋯ Although MISS has continued to make significant progress clinically, consideration must also be given to its economic impact and the learning curve surgeons experience in adding these procedures to their armamentarium. This review examines current innovations in MISS, as well as the economic impact and future directions of the field.

Intraoperative magnetic resonance imaging (iMRI) has been shown to optimize the extent of resection of parenchymal brain tumors. To facilitate the use of preoperative treatment plans after an intraoperative navigation update via iMRI, an elastic image fusion (EIF) algorithm was developed. ⋯ This feasibility study shows that EIF can compensate for surgery-related brain shift in a highly significant manner even in this small number of cases. The establishment of an easy applicable and reliable EIF tool integrated in the clinical workflow could open a large variety of new options for image-guided tumor surgery.
