The presence of intradiscal vacuum phenomenon was associated with increased restoration of disc height and segmental lordosis in patients who underwent lateral lumbar interbody fusion between L1 and L-5 for degenerative lumbar disease, according to recently published results.
Using data from the University of South Florida’s Department of Neurosurgery, researchers performed a retrospective chart review of 140 patients with 247 disc levels treated with lateral lumbar interbody fusion during a 4-year period. Investigators reviewed plain radiographs and CT scans for the presence of the intradiscal vacuum phenomenon (IVP). Disc levels with IVP were compared to disc levels without IVP with regard to preoperative and postoperative posterior disc height (PDH), anterior disc height (ADH) and segmental lordosis (SL). Factors predictive of PDH, ADH and SL were evaluated with linear regression.
