About

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.
