Assesment of Epidural Platelet-Rich Plasma (PRP) Injection During Uniportal Endoscopic Lumbar Disc Herniation Excision on Residual Neuropathies (HERDISPLA)
Assesment of Epidural Platelet-Rich Plasma (PRP) Injection During Uniportal Endoscopic Lumbar Disc Herniation Excision on Residual Neuropathies: An Exploratory Study.
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.

Intervention / Traitement |
|---|---|
|
Expérimental: Epidural PRP injection
PRP collection and injection at the end of surgery (herniated disc 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.

Principaux critères de jugement
Mesure des résultats |
Description de la mesure |
Délai |

Presence of neuropathic pain
Délai: At 6 months follow-up
|
Neuropathic 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)).

|
At baseline, 2 and 6 weeks follow-up and 3, 6 and 12 months follow-up.
|
|
Progression of back pain
Délai: At baseline, 2 and 6 weeks follow-up and 3, 6 and 12 months follow-up

Minimum value is 0, maximum value is 50 (maximum disability)
|
At baseline, 2 and 6 weeks follow-up, and 3, 6 and 12 months follow-up.
|
|
Therapeutic failure
Délai: At 2 and 6 weeks follow-up and 3, 6 and 12 months follow-up
|
Therapeutic failure will be assessed by presence or absence of additional surgery for persistent or worsening pain.
|
At 2 and 6 weeks follow-up and 3, 6 and 12 months follow-up
|
|
Post-operative complications
Délai: From surgery to 30 days follow-up
|
Post-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.
