STUDY DESIGN Retrospective analysis of prospectively collected, nonrandomized radiographical data. OBJECTIVE To examine the relationship between the presence of preoperative metabolically active facet arthropathy (FA) and the amount of indirect foraminal decompression gained after extreme lateral interbody fusion (XLIF). SUMMARY OF BACKGROUND DATA(More)
STUDY DESIGN A prospective single-surgeon nonrandomized clinical study. OBJECTIVE To evaluate the radiographic and clinical outcomes, by fixation type, in extreme lateral interbody fusion (XLIF) patients and provide an algorithm for determining patients suitable for stand-alone XLIF. SUMMARY OF BACKGROUND DATA XLIF may be supplemented with pedicle screw(More)
Triamcinolone-induced alteration of the notochordal-basichondrocranial relationship in the rhesus monkey. Timed-mated pregnant rhesus monkeys received triamcinolone acetonide (10 mg/kg, IM) during early organogenesis. Treated and control embryos and fetuses were removed by hysterotomy on days 35, 42, 50, 60, and 70. All treated cases 42 days or older(More)
INTRODUCTION The lateral transpsoas approach for lumbar interbody fusion (XLIF) is gaining popularity. Studies examining a surgeon's early experience are rare. We aim to report treatment, complication, clinical, and radiographic outcomes in an early series of patients. METHODS Prospective data from the first thirty patients treated with XLIF by a single(More)
OBJECT The use of recombinant human bone morphogenetic protein-2 (rhBMP-2) in anterior lumbar interbody fusion (ALIF) is controversial regarding the reported complication rates and cost. The authors aimed to assess the complication rates of performing ALIF using rhBMP-2. METHODS This is a prospective study of consecutive patients who underwent ALIF(More)
