Free epidural fat-grafting was performed to prevent adhesion between scar tissue of the epidural space and dura and nerve root after lumbar laminectomy.
The results were evaluated using MRI. 15 cases were operated upon with an average follow-up period of 7.5 months.
MRI was recorded and the findings were classified into four types as follows; I, equally high signal case; II, slight fibrosis case; III, severe fibrosis case; IV, high signal disappeared case.
The results showed 3 cases of type I, 7 cases of type II 3 of type III 2 cases of type IV.
According to MRI findings, free epidural fat is supposed to be still viable and alive, although slightly fibrosed but the dural side remains a high signal area.
Free epidural fat-grafting was useful for preventing adhesion around the epidural space.
There was high relation ship to age and sex with regard to viability of the free fat graft.
