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)
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)
We evaluated 14 children with primary ureteropelvic junction obstruction, using preoperative excretory urography and renal imaging with the renal cortical labeling agent 99mtechnetium dimercaptosuccinic acid. All children with a reduction in function of 10 per cent or more in the obstructed kidney had severe calicectasis; others with severe calicectasis had(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)
The lateral approach for anterior interbody fusion allows placement of a large footprint intervertebral spacer to indirectly decompress the neural elements through disc height restoration and resultant soft tissue changes. However, it is not well understood under what circumstances indirect decompression in lateral approach surgery is sufficient. This(More)
