COMPARISON OF FORAMINAL INDIRECT DECOMPRESSION OUTCOMES IN DEGENERATIVE SPONDYLOLISTHESIS AND OTHER DEGENERATIVE LUMBAR DISEASE AFTER MINIMALLY INVASIVE EXTREME LATERAL INTERBODY FUSIONCarlos De La Torre, Khai S. Lam
Purpose
• Lateral recess and neural foramina stenosis commonly results from degenerative changes such as collapsed or bulging discs and spondylolisthesis. • The purpose is to determine which condition benefits more from
indirect decompression with the ELIF approach • Degenerative spondylolisthesis (DS) vs.• Other degenerative disease of the lumbar spine (ODD) (i.e. disc
disease, scoliosis, ASD).
Materials and Methods
• January 2013 and January 2020• 67 subjects• PROMS were collected from 67 patients preoperatively and up to 12
months postoperatively as well as demographic data.• PROMS: ODI, VAS BP, VAS LP, PCS and MCS• Foraminal area was measured on the preoperative and intraoperative
(i.e. after placement of interbody cage)
Conclusion
• In ELIF, indirect decompression is realised through placement of large intervertebral spacers that restore and realign lumbar segments and indirectly decompresses neural elements through disc and foraminal height restoration• Similar improvements in both foraminal area restoration and PROMS • These results corroborate that indirect decompression in ELIF has
shown to be adequate in providing symptom relief in most patients with degenerative spinal conditions
