A new material for prevention of epidural fibrosis after laminectomy: oxidized regenerated cellulose (interceed), an absorbable barrier.

Epidural fibrosis, which may cause persistent back and leg pain, may develop after laminectomy. Several materials have been used in attempts to minimize epidural fibrosis, with varying results. We evaluated the efficacy of an absorbable cellulose adhesion barrier in preventing epidural fibrosis.
