Prediction of TEI Success in Sciatica

Recruiting
Conditions
Lumbar Radiculopathy
Lumbar Disc Herniation
Lumbar Spinal Stenosis
Interventions
Drug: Transforaminal Epidural Injection
Registration Number
NCT04540068
Lead Sponsor
Eduard Verheijen
Brief Summary

Rationale: Treatment with transforaminal epidural injections is part of usual care in patients suffering from lumbar radiculopathy. However, not all patients experience a satisfactory result from this treatment and it is unclear what percentage of patients responds well and if any clinical or radiological factors exist that predict a positive response.

Objectives:

Primary: to develop a model based on demographic, clinical and radiological parameters for prediction of treatment success after TEI

Secondary: to estimate the short-term efficacy of TEI in patients with LDH and spinal stenosis based on pain, functionality and perceived recovery scores, to determine the correlation between clinical and radiological baseline parameters and physical and psychological patient outcome measures, to determine the rate of additional injections and rate of surgery after treatment with TEI, to determine the short-term (cost)effectiveness of TEI on physical and psychological patient outcome measures, and to determine the rate of complications associated with TEI

Study design: Prospective cohort study

Study population: Patients that are scheduled for TEI as part of usual care suffering from a new episode of lumbar radiculopathy

Main study parameters/endpoints: leg and back pain scores at baseline, 30 minutes, 2 and 6 weeks after treatment. ODI, HADS, Quality of Life and PCI at baseline, 2 and 6 weeks after treatment. Perceived recovery at 2 and 6 weeks after treatment. Usage of healthcare at baseline, 2 and 6 weeks after treatment.
