Comorbidity-Specific Risk of Revision Following Single-Level Degenerative Spinal Fusion (2010-2023): US Cohort Study Among Over 399K Patients.

STUDY DESIGN Retrospective cohort. OBJECTIVE To evaluate the associations of 28 preoperative comorbidities with all-cause and etiology-specific revisions (pseudarthrosis, mechanical failure, adjacent segment disease [ASD], infection) following single-level degenerative spinal fusion. SUMMARY OF BACKGROUND DATA Revi...

Full versus partial correction of pelvic incidence-lumbar lordosis mismatch in lumbar fusion: a systematic review and meta-analysis.

Reverse pedicle subtraction osteotomy for iatrogenic hyperlordosis in a scoliosis patient: illustrative case

BACKGROUND Overcorrection of lumbar lordosis (LL) during deformity surgery can create iatrogenic hyperlordosis with negative sagittal balance, a rare but disabling complication with no standard treatment. OBSERVATIONS A 21-year-old woman with adolescent idiopathic scoliosis had undergone T3–L5 fusion, revision L4–5 tra...

3D-Printed Guides, Navigation, and Robotic Assistance in Spinal Instrumentation: A Network Meta-Analysis of Pedicle Screw Accuracy and Clinical Outcomes.

BACKGROUND Accurate pedicle screw placement is essential to prevent neurovascular injury, revision surgery, and excess healthcare costs. While navigation and robotic systems enhance accuracy over freehand or fluoroscopic techniques, they remain limited by high cost and patient radiation exposure. Three-dimensional prin...
