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.

Presence of neuropathic pain
Prazo: 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

|
At baseline, 2 and 6 weeks follow-up, and 3, 6 and 12 months follow-up.
|
|
Therapeutic failure
Prazo: 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
Prazo: 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.
