Study design: Retrospective cross-sectional study. Objective: (1) To determine the incremental increase in intraoperative ionizing radiation conferred by CT as compared to conventional radiography; and (2) To model different lifetime…
Study design: Retrospective database analysis. Objective: To elucidate trends in the utilization of IONM during elective lumbar surgery procedures and to investigate the association between the use of IONM and…
Purpose: In response to sagittal malalignment, compensatory spinal and lower extremity mechanisms are recruited. Thoracolumbar realignment surgery has been shown to yield reciprocal changes in these compensations. Thus, whole-body radiographic…

Study design: Retrospective analysis. Objectives: To calculate the range of minimum clinically important difference threshold values using anchor-based and distribution-based methods for back pain, leg pain, the Oswestry Disability Index…
Introduction: In structural thoracolumbar/lumbar (TL/L) curves, lowest instrumented vertebra is selected mostly as the lower end vertebra (LEV). To save more lumbar mobile segments, fusion may be stopped one level…
Introduction: As an increasing number of lumbar fusion procedures are being conducted at specialty hospitals and surgery centers, appropriate patient selection and risk stratification is critical to minimizing patient transfers.…
Objectives: To assess lumbar sympathetic chain (LSC) relation to the surgical corridor for oblique lumbar approach and the ability to mobilize the LSC. Methods: Forty-three cadavers were included. Left-sided anterior…
