TREATMENT OF LUMBAR DISC HERNIATIONS IN DEGENERATIVE
SPONDYLOLISTHESIS

For the patients with lumbar disc herniation with a progressive neurogoic deficit,
operative intervention is necessary. The conventional surgical treatment is open
discectomy with laminotomy. Degenerative spondylolisthesis is a condition of older
people, and defined as the presence of forward slippage of a vertebral body in the
presence of an intact neural arch. It has been reported that either laminectomy or
laminotomy may carry the risk of developing a progression of slip and instability. The
recent development of a working channel scope and percutaneous endoscopic
procedures make it possible to remove lumbar disc herniations effectively without
any damage to intact neural arch.Objective: To evaluate the clinical efficacy of PELD
for the treatment of lumbar disc herniations in degenerative spondylolisthesis.
Materials and Methods: Five patients presented with lumbar disc herniations in
Degenerative Spondylolisthesis underwent PELD. All the patients had lumbar disc
herniation with a progressive neurogoic deficit. Under local anesthesia, the 6mm
working channel endoscope was introduced into the epidural space. Herniated disc
material was removed using forceps and laser under clear endoscopic visualization.
Clinical and radiological data was reviewed postoperatively with the minimum followup
of 1 years. Patient satisfaction was evaluated by the Macnab’s criteria of latest
follow-up. Results: All the patients showed excellent outcome at their latest follow-up.
There was no progression of slip at their latest follow-up standing radiographs.
Conclusion: PELD is a effective method for the the treatment of lumbar disc
herniations in degenerative spondylolisthesis.
