STUDY DESIGN: Prospective cohort study.OBJECTIVE: To compare the long-term, radiographic coronal and sagittal outcomes of these two approaches at 10-year follow-up.SUMMARY OF BACKGROUND DATA: Both anterior and posterior instrumented fusions…
STUDY DESIGN: A retrospective study.OBJECTIVE: To evaluate the effect of degeneration of paraspinal muscles, including psoas muscles, erector spinae muscles and multifidus muscles on pedicle screw loosening at lower instrumented…
STUDY DESIGN: Retrospective cohort.OBJECTIVE: We present a universal model of risk prediction for patients undergoing elective cervical and lumbar spine surgery.SUMMARY OF BACKGROUND DATA: Previous studies illustrate predictive risk models…
PURPOSE: To define and analyze the learning curve of percutaneous endoscopic transforaminal decompression (PETD) for lumbar spinal stenosis (LSS).METHODS: From July 2015 to September 2016, 78 patients underwent PETD; one…
The pathogenesis of lumbar adjacent segment disease is thought to be secondary to altered biomechanics resulting from fusion. Direct in vivo evidence for altered biomechanics following lumbar fusion is lacking.…
STUDY DESIGN: Retrospective Study OBJECTIVE.: The purpose of this study is to determine how BMI affects patient reported outcome measurements (PROMs) after lumbar fusions.SUMMARY OF BACKGROUND DATA: Although greater preoperative…
STUDY DESIGN: A retrospective cohort study.OBJECTIVE: The purpose of this study was to evaluate marijuana usage and its effect on outcomes following transforaminal lumbar interbody fusion (TLIF).SUMMARY OF BACKGROUND DATA:…
