Retroperitoneal oblique approach to lumbar spine used surgical corridor between psoas muscle and aorta for exposure to anterior part of lumbar spine. Lumbar sympathetic chain (LSC) runs in the corridor to make it a structure at risk of injury. ⋯ LSC moves away from psoas muscle and becomes closer to aorta in L4-5 disc level.

Multicenter Study Observational Study
Magnetic resonance spectroscopy (MRS) can identify painful lumbar discs and may facilitate improved clinical outcomes of lumbar surgeries for discogenic pain.
The goal of this study was to refine clinical MRS to optimize performance and then determine whether MRS-derived biomarkers reliably identify painful discs, quantify degeneration severity, and forecast surgical outcomes for chronic low back pain (CLBP) patients. ⋯ MRS correlates with PD and may support improved surgical outcomes for CLBP patients. Noninvasive MRS is a potentially valuable approach to clarifying pain mechanisms and designing CLBP therapies that are customized to the patient.

To evaluate whether 3D-printed vertebrae offer realistic haptic simulation of posterior pedicle screw placement and decompression surgery with normal to osteoporotic-like properties. ⋯ In this pilot study, 3D-printed vertebrae displayed haptically and biomechanically realistic simulation of posterior spinal procedures and outperformed Sawbones. This approach enables surgical training on bone density-specific vertebrae and provides an outlook toward future preoperative simulation on patient-specific spine replicas.

Sacroiliac joint (SIJ) dysfunction is an underdiagnosed condition. Several published cohorts have reported favorable midterm outcomes after SIJ fusion using titanium implants placed across the SIJ. Herein, we report 12-month follow-up from SIJ fusion in a standard clinic setting. ⋯ In standard clinical practice, SIJ fusion with triangular titanium implants produces significant improvement in pain and disability related to SIJ dysfunction.

'After-hours' non-elective spinal surgeries are frequently necessary, and often performed under sub-optimal conditions. This study aimed (1) to compare the characteristics of patients undergoing non-elective spine surgery 'After-hours' as compared to 'In-hours'; and (2) to compare the perioperative adverse events (AEs) between those undergoing non-elective spine surgery 'after-hours' as compared to 'in-hours'. ⋯ Non-elective spine surgery performed 'after-hours' is independently associated with increased risk of perioperative adverse events, length of stay and possibly, mortality. Research is needed to determine the specific factors contributing to poorer outcomes with 'after-hours' surgery and strategies to minimize this risk.
