Overview
Brief Summary
Chronic neuropathic pain following lumbar spine surgery is often under-diagnosed and difficult to relieve. It can persist long after the operation, sometimes for months or even years, and has a major impact on the quality of life of patients who suffer from it. However, the scientific literature on the subject remains relatively poor, as evidenced by the absence of scientific studies on the prevalence of neuropathic pain after lumbar spinal surgery, whether instrumented or not.
The main aim of this study is to determine whether lumbar spine surgery has an impact on the prevalence of neuropathic pain. Participants will be followed up and complete a quality-of-life questionnaire for one year after surgery.

Outcomes
Primary Outcomes
Comparison of the proportion of patients with neuropathic pain between the day before surgery and 12 months after surgery.
Time Frame: The day before surgery and 12 months after surgery
Comparison of the proportion of patients with a score ≥ 4 measured with the DN4 questionnaire one day before surgery and 12 months after surgery. The DN4 questionnaire (4-question neuropathic pain scale) is a diagnostic tool used to identify and assess neuropathic pain. The questionnaire aims to measure the presence of symptoms and signs commonly associated with neuropathic pain. The questionnaire comprises 10 items: * 7 items relate to the patient's description of his or her pain (burning, painful cold, electric shocks, tingling, numbness, itching). * 3 items are based on the clinician's sensory examination, focusing on touch and pinprick hypoesthesia, as well as brush-induced allodynia. The DN4 is scored out of 10 points. A score of 4 or more suggests the presence of neuropathic pain.
Secondary Outcomes
- Evolution of post-operative neuropathic pain(At 1, 3 and 6 months after surgery)
- Evolution of overall pain(The day before surgery and at 1, 3, 6 and 12 months after surgery)
- Evolution of functionality and disability of patients(The day before surgery and at 1, 3, 6 and 12 months after surgery)
- Evolution of quality of life measured with EQ-5D-5L(The day before surgery and at 1, 3, 6 and 12 months after surgery)
