Using clinical and radiographic variables to predict intracranial aneurysm rupture status with machine learning.

Background: With excitement in the medical community around artificial intelligence, machine learning (ML) techniques have been applied to correlate clinical and radiographic variables with intracranial aneurysm (IA) rupture status. In this study, we applied various ML techniques, including random forest (RF), XGBoost (XGB), support vector machines (SVM), and multi-layer perceptron (MLP), to predict IA rupture status.

Methods: The dataset consisted of 178 IAs each with 53 clinical and radiographic features for analysis.

Validation of a Mathematical Model for Rupture Status of Spherical Intracranial Aneurysms.

Purpose: An accurate mathematical model of intracranial aneurysm (IA) mechanics is of great value for its potential utility in assessing probability of IA rupture. Such a model for spherical IAs has been developed which predicts a wall-thickness-to-IA-radius ratio (WTR) of 6.1 × 10 at which IAs rupture.

Inter-modality correlation across invasive and noninvasive angiography in the three-dimensional assessment of cerebral aneurysms.

Background: Non-invasive and invasive methods of cerebral angiography, including computed tomography angiography (CTA), magnetic resonance angiography (MRA), and digital subtraction angiography (DSA), are commonly used to characterize and follow cerebral aneurysms. Prior work has validated two-dimensional size measurements across these modalities. Our study aims to compare the reliability of three-dimensional (3D) shape measurements across CTA, MRA, and DSA.

Correlation Between Rod Fracture and Shear Stress: A Novel Parameter.

Background: We sought to assess the accuracy of a novel parameter proportional to the rod shear stress (RSS) in identifying patients at risk of rod fracture (RF) after surgery for correction of adult spinal deformity.

Methods: We performed a retrospective medical record review of patients aged ≥18 years treated for adult spinal deformity between 2004 and 2014 with ≥24 months of follow-up. The primary outcome was RFs identified radiographically.

Synthetic Interbody Devices and Traditional Bone Graft Are Associated With a Similar Rate of Surgical Complications After 1-2 Level Anterior Cervical Discectomy and Fusions.

Study Design: Retrospective cohort.

Objective: To compare the rates of all-cause surgical complications of synthetic interbody devices versus allograft or autograft in patients undergoing 1-2 levels anterior cervical discectomy and fusion (ACDF) procedures.

Summary Of Background Data: Cervical degenerative disorders affect up to 60% of older adults in the United States.

No Difference in Surgical Outcomes Between Stand-Alone Devices and Anterior Plating for 1-2 Level Anterior Cervical Discectomy and Fusion: A 1:1 Exact Matched Analysis.

Study Design: Retrospective cohort.

Objective: To compare rates of all-cause surgical and medical complications between zero-profile (ZP; stand-alone) implants versus any graft type with an anterior plate in patients undergoing 1-2 level anterior cervical discectomy and fusion (ACDF) for treatment of degenerative cervical myeloradiculopathy.

Summary Of Background Data: Degenerative cervical myeloradiculopathy is increasingly prevalent in older adults.

Surgeon Experience Matters: An Exact Matched Analysis of TLIF Outcomes Demonstrates No Difference in Surgical Outcomes Between Experienced Neurosurgeons and Orthopedic Surgeons.

Study Design: Retrospective cohort study.

Objective: To compare surgical and medical complications profile between neurosurgeons and orthopedic surgeons after transforaminal lumbar interbody fusion (TLIF) procedures.

Background: Studies comparing the impact of spine surgeon specialty (neurosurgery vs.

Cannabis Use is Associated With Higher Rates of Pseudarthrosis Following TLIF: A Multi-Institutional Matched-Cohort Study.

Study Design: This was a retrospective cohort study.

Objective: To compare the rates of pseudarthrosis in patients undergoing 1 to 3 level transforaminal lumbar interbody fusion (TLIF) procedures between cannabis users and noncannabis users.

Summary Of Background Data: Recreational use of cannabis is common, though it remains poorly studied and legally ambiguous in the United States.
