The role of interspinous devices (ISD) after lumbar herniated disc surgery for the prevention of postoperative back pain is controversial. The aim of this comparative prospective study was to determine outcomes in a selective cohort with L5-S1 disc herniation and degenerative disc changes after microdiscectomy with or without insertion of an ISD. One hundred and two consecutive patients underwent an L5-S1 microdiscectomy with or without implantation of an ISD. Group 1 consisted of 47 patients, with mild (n=22), moderate (n=14) or severe (n=11) degenerative disc changes who had microdiscectomy alone.…Detalles
