Epidural scarring after lumbar disc surgery: Equivalent scarring with/without free autologous fat grafts.

ABSTRACT: To limit epidural fibrosis and prevent scar formation/nerve tethering that may contribute to chronic postoperative pain; some surgeons have utilized epidural autologous fat grafts following lumbar microdiscectomy.We investigated the correlation between post-microdiscectomy epidural scarring [including select magnetic resonance imaging (MRI) studies] and clinical outcomes in 36 patients operated for symptomatic. MRI documented L4-L5 and L5-S1 disk herniations with (18 patients) and without (18 patient) the application of free fat grafts. In addition, histological evaluation of the original fat grafts was performed in 4 patients requiring additional surgery.We found no clear association between the use of autologous graft fats and the clinical outcomes in this study.In this preliminary study involving only 36 patients, the prospective randomized use of free autologous fat grafts did not appear to influence outcomes following microdiscectomy.
