The proposal of C1-C2 fusion as a better treatment option compared with foramen magnum decompression (FMD) for the treatment of Chiari 1 malformations has led to controversy. Although FMD is a time-tested treatment option, a group of patients exists who will benefit from C1-C2 fusion. We have proposed an objective system for defining complex Chiari malformations and studied the outcomes of fusion with decompression versus decompression alone for these patients. ⋯ We have proposed a novel set of criteria for defining complex Chiari malformations. Fusion with decompression provided better outcomes than decompression alone.

Effective pain control is vital for successful surgery in the ambulatory setting. Our study aims to characterize a case series of patients who underwent lumbar decompression (LD) in the ambulatory surgical center (ASC) with the use of a multimodal analgesic (MMA) protocol. ⋯ This is the largest clinical case series focused on LD procedures within an ASC requiring no planned 23-hour observation. This study demonstrates the feasibility of performing LD surgery in an ASC with proper patient selection, surgical technique, and MMA protocol. All patients were discharged from the surgical center on the same day of surgery.

Enhanced recovery after surgery has been attempted in neurosurgery at a greater rate. However, concern exists regarding the feasibility of using enhanced recovery after neurosurgery (ERANS). How to manage available resources to safely perform ERANS and improve clinical outcomes has been the subject of much debate and discussion. ⋯ Applying an ERANS protocol was feasible, associated with a low incidence of complications, and acceptable intensive care unit and postoperative hospital lengths of stay. The findings from the present study might provide a new approach for the further research of ERANS.

Fixation Strength of Modified Iliac Screw Trajectory Compared to Traditional Iliac and S2 Alar-Iliac Trajectories: A Cadaveric Study.
Traditional iliac (TI) screws require extensive dissection, involve offset-connectors, and have prominent screw heads that may cause patient discomfort. S2 alar-iliac (S2AI) screws require less dissection, do not need offset connectors, and are less prominent. However, the biomechanical consequences of S2AI screws crossing the alar-iliac joint is unknown. The present study investigates the fixation strength of a modified iliac (MI) screw, which has a more medial entry point and reduced screw prominence, but does not cross the alar-iliac joint. ⋯ No statistically significant differences were found between the TI, S2AI, and MI techniques with regard to screw toggle or rod strain. Advantages of the MI screw include its lower profile and a medialized starting point eliminating the need for offset-connectors.

To identify rates of and factors associated with repeat revascularization in a large cohort of patients prospectively followed over 10 years in Carotid Revascularization Endarterectomy versus Stenting Trial. ⋯ A low rate of repeat revascularization was seen without any significant difference among patients who underwent CEA or CAS over 10 years. The 6.7% rate of composite end point within 30 days after procedure highlights the need for standardizing the indications for repeat revascularization.
