Percutaneous HydroDiscectomy Compared to TESI for Radiculopathy

Stopped early · Phase 4

Conditions studied: Lumbar Herniated Disc

In brief

To compare the outcomes of percutaneous lumbar Hydrodiscectomy (HydroD) with the SpineJet Hydrodiscectomy System to transforaminal epidural steroid injections (TESI) in patients with lumbar radiculopathy due to contained disc herniation with symptoms that persist following a treatment course of conservative management including physical therapy and anti-inflammatory medication.
