Article Synopsis
  • The study evaluates the effectiveness of two surgical methods, minimally invasive posterior cervical foraminotomy (MIS-PCF) and anterior transcorporeal approach (ATCA), for treating cervical radiculopathy.
  • A systematic review analyzed data from 40 studies and found that both techniques had similar complication and reoperation rates, along with comparable blood loss and operation time.
  • However, the ATCA technique resulted in a significantly greater reduction in neck pain, as measured by the visual analog scale (VAS), indicating it might be the better option for relieving symptoms.

Introduction: Interbody fusion is commonly utilized for arthrodesis and stability among patients undergoing spine surgery. Over the last few decades, interbody device materials, such as titanium and polyetheretherketone (PEEK), have been replacing traditional autografts and allografts for interbody fusion. As such, with the exponential growth of bioengineering, a large variety cage surface technologies exist.

Background: The adoption of the transradial approach (TRA) has been increasing in popularity as a primary method to conduct both diagnostic and therapeutic interventions. As this technique gains broader acceptance and use within the neuroendovascular community, comparing its complication profile with a better-established alternative technique, the transfemoral approach (TFA), becomes more important. This study aimed to evaluate the safety of TRA compared with TFA in patients undergoing diagnostic, therapeutic, and combined neuroendovascular procedures.

Background: The utility of intraoperative neurophysiological monitoring (IONM) is well established for some spine surgeries (eg, intramedullary tumor resection, scoliosis deformity correction), but its benefit for most degenerative spine surgery, including anterior cervical discectomy and fusion (ACDF), remains debated. National datasets provide "big data" approaches to study the impact of IONM on spine surgery outcomes; however, if administrative coding in these datasets misrepresents actual IONM usage, conclusions will be unreliable. The objective of this study was to compare estimated rates (administrative coding) to actual rates (chart review) of IONM for ACDF at our institution and extrapolate findings to estimated rates from 2 national datasets.

Article Synopsis
  • A study was conducted to evaluate the outcomes of direct pars repair for lumbar spondylolysis, a condition affecting 5%-8% of adults.
  • Researchers reviewed cases where patients underwent open fracture reduction and were treated with cannulated screws, collecting data on demographics, clinical presentation, and postoperative results.
  • The results showed that all three patients experienced symptom relief and returned to manual labor, with a high rate of fusion and good screw placement confirmed in follow-up imaging, indicating that the treatment is safe and effective even if fusion isn't achieved.

Background: Lifestyle modifications and advances in surgical and endovascular techniques for treating unruptured intracranial aneurysm (UIA) have vastly evolved over the last few decades and may have reduced the incidence of aneurysmal subarachnoid hemorrhage (aSAH). However, the actual impact of these changes on the rates and outcomes of aSAH remain unexplored. Thus, we studied national aSAH admissions and outcome trends and changes of major risk factors over time.
