Brief summary

The aim of this study is to assess neuropathic pain in the lower limb at 6 months post-operation in patients who have undergone surgery for a lumbar disc herniation using single-port endoscopic discectomy combined with an epidural PRP injection. This study is based on the hypothesis that intraoperative epidural administration of PRP during discectomy may improve healing, reduce nerve inflammation and potentially minimise post-operative pain and complications. Participants will perform an epidural PRP injection and questionnaires as part of this research.

Interventions

PROCEDUREUniportal endoscopic lumbar disc herniation removal

PRP is obtained from the patient's own blood, prepared, and subsequently reinjected into the patient at the end of uniportal endoscopic lumbar disc herniation removal.

Design outcomes

Primary

MeasureTime frameDescription
Presence of neuropathic painAt 6 months follow-upNeuropathic pain will be assessed with DN-4 questionnaire. If the score is 4 or higher, the test is considered positive (0 is the minimum value, 10 the maximum value (the worst pain)).

Secondary

MeasureTime frameDescription
Progression of leg radicular painAt baseline, 2 and 6 weeks follow-up and 3, 6 and 12 months follow-up.Progression of leg radicular pain will be assessed with a numerical rating scale (0 is the minimum value (no pain), 10 is the maximum value (the worst pain))
Progression of back painAt baseline, 2 and 6 weeks follow-up and 3, 6 and 12 months follow-upProgression of back pain will be assessed with a numerical rating scale (0 is the minimum value (no pain), 10 is the maximum value (the worst pain))
Progression of disabilityAt baseline, 2 and 6 weeks follow-up, and 3, 6 and 12 months follow-up.Progression of disability will be assessed by ODI questionnaire. Minimum value is 0, maximum value is 50 (maximum disability)
Progression of neuropathic painAt baseline, 2 and 6 weeks follow-up and 3, 6 and 12 months follow-upThe progression of neuropathic pain will be assessed with DN-4 questionnaire, at all follow-up visit compared to baseline. 0 is the minimum value, 10 the maximum value (the worst pain).
Post-operative complicationsFrom surgery to 30 days follow-upPost-operative complications will be assessed on the occurrence of at least one complication within 30 days of the procedure, specifically including neurological deficits, infections and allergic reactions.
Presence of neuropathic painAt 2 and 6 weeks follow-up and 3, 6 and 12 months follow-upNeuropathic pain will be assessed with DN-4 questionnaire. If the score is 4 or higher, the test is considered positive (0 is the minimum value, 10 the maximum value (the worst pain)).
Therapeutic failureAt 2 and 6 weeks follow-up and 3, 6 and 12 months follow-upTherapeutic failure will be assessed by presence or absence of additional surgery for persistent or worsening pain.
