Article Synopsis
- The current method for assessing pedicle screw loosening relies heavily on radiation-emitting imaging, which can be unreliable in certain cases.
- The authors propose a new, radiation-free technique using vibroacoustic sensing that involves exciting the vertebrae with vibrations and measuring them with a sensitive sensor attached to the screw.
- The new method has been validated through simulations and physical tests on cadaveric lumbar spine specimens, achieving high sensitivity and specificity in detecting loose implants.
Article Synopsis
- Increasing use of spinal instrumentation has led to the development of 3D surgical navigation to improve implant placement accuracy, but challenges like high radiation exposure and workflow disruptions have limited its adoption.
- The X23D is a new AI-driven technique that creates a 3D spinal model from just four fluoroscopy images, designed to assist in real-time surgical navigation for placing lumbar pedicle screws.
- An ex-vivo study found that while X23D navigation and traditional fluoroscopy had similar breach rates and execution times for screw placements, X23D showed reduced radiation exposure, indicating potential for further refinement and clinical use.
Introduction: Previous studies show heterogeneity when applying estimated glomerular filtration (eGFR) equations to kidney transplant recipients (KTRs). However, research on the impact of transplantation-related characteristics on eGFR equations using creatinine (eGFRcr) compared to cystatin C (eGFRcys) is scarce.
Methods: We conducted a comprehensive analysis with three eGFRcr equations (Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) 2009, European Kidney Function Consortium (EKFC) 2021, kidney recipient specific-glomerular filtration rate KRS-GFR) 2023), comparing them to two eGFRcys (CKD-EPI 2012 and EKFC 2023) in 596 KTRs.
Study Design: Heterogeneous data collection via a mix of prospective, retrospective, and ambispective methods.
Objective: To evaluate the effect of biological sex on patient-reported outcomes after spinal fusion surgery for lumbar degenerative disease.
Summary Of Background Data: Current literature suggests sex differences regarding clinical outcome after spine surgery may exist.
Spinal fusion surgery requires highly accurate implantation of pedicle screw implants, which must be conducted in critical proximity to vital structures with a limited view of the anatomy. Robotic surgery systems have been proposed to improve placement accuracy. Despite remarkable advances, current robotic systems still lack advanced mechanisms for continuous updating of surgical plans during procedures, which hinders attaining higher levels of robotic autonomy.
