Percutaneous Discectomy to Treat Symptomatic Lumbar Disc Herniation : Evaluation of Clinical Efficiency, Patient Reported Outcomes and Economical Impact by Assessing Time Before Return to Work and Duration of Hospitalization Stay

Percutaneous Lumbar Discectomy : Evaluation of Patient Reported Outcomes, Aconomical Impact and Return to Work

This study aims to evaluate the clinical (pain) and functional (patient reported outcomes) efficacy of percutaneous discectomies under CT guidance to treat lumbar disc herniations resistant to conservative treatment and nerve root infiltrations.

The aim is also to evaluate the economic impact of the procedure, mainly through the length of hospitalization and the time to return to work.

Patients were evaluated initially before surgery and then at 1, 3 and 6 months.

Inclusion Criteria:

• radiculalgia related to lumbar disc herniation with clinical radiological concordance
• age > 18
• resistance to conservative treatment and nerve root infiltrations

Exclusion Criteria:

• prior discal surgery at the same level,
• lumbar canal stenosis,
• extruded discal herniation,
• neurological deficit,
• no capacity to answer to follow-up calls
