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.
