JULIET®TL Study #30001

The JULIET®TL, lumbar intersomatic Poly-Ether-Ether-Ketone cage used for symptomatic degenerative disc diseases treatment by arthrodesis. Safety and effectiveness evaluation after two years follow-up

Investigator initiated study

FDA approved for this indication

Region: France

Status: Completed


Post CE-Marking Follow-up Study submitted to HAS (FR)


Primary Objectives:

Safety of JULIET®TL, lumbar inter-somatic cage, evaluation based on all events observed

(controls, investigations, hospitalizations, interventions) during 2 year follow-up after arthrodesis:
• Overall performance of JULIET®TL, evaluated at the end of 2 years follow-up period, as a composite

primary endpoint, based on data at last visit:

- Incidence and seriousness of implant related complications
- Absence of lumbar and radicular pain
- Absence of neurologic disorders (sensitive and/or motor)
- Fusion status
- Patient satisfaction
- Global prognostic


Secondary objectives:

Early qualitative effectiveness evaluation, at 2 months after surgery for lumbar arthrodesis using JULIET®PO:

•  Overall success evaluated by Stauffer criteria:

- Pain relief
- Time after surgery for getting back to work
- Diminution of physical activities
- Pain medication

•  Functional improvement evaluated by Lassale criteria:

- Claudication
- Radicular pain (at rest and at effort)
- Lumbar pain
- Neurologic disorders
- Pain medication
- Kinesitherapy
- Time after surgery for getting back to normal life

•  Radiologic criteria:

- Implant positioning
- Radicular compression


Indication - condition:

Symptomatic lumbar disc degenerative disease
