Minimally invasive surgery through endoscopic laminotomy and foraminotomy for the treatment of lumbar spinal stenosis

摘要

BackgroundLumbar spinal stenosis is a common cause of radicular and generalized back pain among older adults. Endoscopic minimally invasive surgery, in contrast to open decompression, may provide the opportunity for a less invasive surgical intervention. Thus, the purpose of this study is to evaluate the safety (operative complications, estimated blood loss, operative room time) and effectiveness (pre- versus postoperative level of disability and pain severity) of minimally invasive surgery using endoscopic laminotomy and foraminotomy among a large sample of patients with lumbar spinal stenosis.
