====== Epidural free fat graft ======

The use of an autogenous free [[fat graft]] in the [[epidural space]] has been employed in an attempt to reduce post-op epidural [[scar]] formation. Opinion varies widely as to the effectiveness, some feel it is helpful, others feel it actually exacerbates scarring
((Dunsker SB. Comment on Cobanoglu S, et al.: Complication of Epidural Fat Graft in Lumbar Spine Disc Surgery: Case Report. Surg Neurol. 1995; 44:481–482)).
In some patients, no evidence of the graft will be found on reoperation years later. The fat graft can very rarely be a cause of nerve root compression

within the first few days post-op, and there is a case report of compression 6 years following surgery
