NCT05776628

Brief Summary

The goal of this clinical trial is to compare if adding a polydioxanone membrane prevents epidural fibrosis and, consequently, the rate of occurrence of the post-laminectomy syndrome in participants undergoing microdiscectomy for treatment of disc herniation.

Conditions

Outcome Measures

Primary Outcomes (1)

  • Patient's quality of life

    Assessed by the Oswestry Questionnaire for lumbar evaluation (The low back pain disability Oswestry questionnaire).

    Change from the baseline, to immediate potostoperative period (14 days) and to late postoperative period (6 months).

Secondary Outcomes (4)

  • Epidural fibrosis

    6 months postoperatively.

  • Patient's quality of life

    Before the procedure, in the immediate postoperative period (14 days) and in the late postoperative period (6 months).

  • Low back and leg pain

    Before the procedure, in the immediate postoperative period (14 days) and in the late postoperative period (6 months).

  • Intervention safety

    Through study completion, an average of 6 months

Study Arms (2)

Polydioxanone membrane

ACTIVE COMPARATOR

After flavectomy and manipulation of the spinal nerve and dura mater to resect the herniated intervertebral disk, the membrane will be placed on top of the dura mater.

Device: Plenum® Tissue ortho membrane (polydioxanone membrane)

Control

NO INTERVENTION

The microdiscectomy procedure will be performed routinely, without the addition of any device over the dura mater.

Interventions

Membrane addition after flavectomy and spinal nerve and dura mater manipulation.

Polydioxanone membrane
