Effect of sagittal plane deformity of the lumbar spine on epidural fibrosis formation after laminectomy: an experimental study in the rat.

Study Design: An animal model of postlaminectomy lumbar column sagittal plane deformity was designed in rats.

Objectives: To analyze the effect of lumbar column deformity (lordosis and kyphosis) on postlaminectomy epidural fibrosis formation.

Summary Of Background Data: Incidence of peridural fibrosis formation after lumbar spinal surgery is considerably high.
