Summary

The main objective of the study is to compare the onset of adjacent segment disk degeneration in two groups of patients (one "spinal fusion group" and one "lumbar arthroplasty with disc replacement" group) with each patient acting as their own control for either group under study and more than three years of follow-up.

Detailed description

This is a non-randomized prospective monocentric open cohort study. Patients whose surgical intervention goes back to more than 3 years will be preselected from the KEOPS database and contacted by phone. Information on the study and its restrictions is delivered to the patient. The investigator organizes the inclusion visit. The patient is seen for consultation by the orthopedic surgeon (inclusion visit /end of research) ; the information notice is given to the patient who is free to ask questions about the study. The patient's consent is collected. The investigator proceeds with a clinical examination (the Lasègue manoeuver), evaluates pain (EVN, DN4) and administers four different questionnaires . The patient is then oriented towards the imaging department where he/she will have the benefit of and Magnetic Resonance Imaging and also a spinal X-ray(front and profile ; Roussouly classification). The patient's participation in the study ends once the examination is over. The consultation in the orthopedic department and the imaging session will be planned in such a way that they can be performed all on the same day. The study program provides for 12 months of inclusion and 4 months of data management, statistical analysis and writing up the report on the study.

Interventions

Type	Name	Description
OTHER	Consultation involving pain evaluation, questionnaires and the Lasègue Manoeuver	Raising the lower limb with the knee in extension reproduces sciatica pain if there is an impression of discal pain with its origin at the roots of the sciatica nerve L5 and S1. This test is evaluated by the degree of elevation of the lower limb relative to the examination table. During the Lasègue manoeuvre the sciatica pain is improved during dorsal flexion of the foot.The doctor notes whether the Lasègue manoeuvre done on the healthy side exacerbates the pain on the opposite side. It is said that contralateral Lasègue sign is positive.
OTHER	Magnetic Resonance Imaging of the lumbar spine	Sagittal proton density-weighted Dixon sequence on the lumbar spine and axial T2-weighted spin echo sequence on the lumbar discs.
