Prevalence of Neuropathic Pain After Non-instrumented Lumbar Spinal Surgery

Prevalence of Neuropathic Pain After Non-instrumented Lumbar Spinal Surgery

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.

Inclusion criteria:

• Patients admitted for scheduled primary lumbar spine surgery without pedicle osteosynthesis or interbody cage.
• Pathology concerned by programmed surgery: herniated disc or lumbar spinal stenosis, uncomplicated by motor or sphincter deficits.
• Delay between 1st painful symptoms and surgery > 48h.

Non-inclusion criteria:

• Surgery scheduled within 48 hours of onset of symptoms.
• Presence of cauda equina syndrome
• Presence of motor-radicular deficit
• Patients with neurological pathology prior to surgery
• Major cognitive or sensory disorders preventing completion of the self-questionnaire
• Patients under guardianship
• Patients not covered by French social security.
• Patients who develop an identified neurological pathology after surgery, regardless of the initial surgery (e.g. multiple sclerosis, spinal cord injury, etc.).
