Percutaneous transforaminal endoscopic lumbar discectomy with intervertebral foramen expanding plasty under the protective working tube in the treatment of lumbar intervertebral disc herniation

Abstract

Objective To discuss the safety and effectiveness of percutaneous transforaminal endo-scopic lumbar discectomy (PELD) with intervertebral foramen expanding plasty under the protective working tube. Methods Ninety-six patients with lumbar intervertebral disc herniation were underwent PELD in pro-tecting with working tube. The situation of the intervertebral foramen expand plasty and fibrous ring protection were observed. VAS and ODI of all patients before operation and at 7 d, 3 months, 6 months, 12 months after operation were evaluated and compared. MacNab method was used to assess the efficacy of treatment. Results The situation of the intervertebral foramen expanding plasty and fibrous ring protection were good. Com-pared with preoperation, VAS and ODI were both significantly reduced in different evaluation time points after operation (P<0.05). The efficacy evaluation results were excellent in 70 cases, good in 22 cases, general in 4 cases, poor in 0 case, the excellent and good rate was 95.8%. No nerve damage and other complications were found. Conclusion Intervertebral foramen expanding plasty under the protective working tube in the applica-tion of PELD is safe and effective for the treatment of intervertebral disc herniation.
