title: Variable segmental plating for the treatment of spinal instability.
abstract: 1. Posterior lumbar interbody fusion (PLIF) incorporates variable screw placement and slotted plates with transpedicular screws to correct spondylolisthesis, a subluxation or displacement of the vertebrae. 2. The indications for PLIF include degenerative disc disease, recurrent disc herniation, spinal stenosis including the central and lateral foraminal varieties, various forms of instability associated with these disorders, and cases of asymptomatic spondylolysis with or without spondylolisthesis. 3. Complications include infection, fracture of the pedicle, nerve root impingement associated with the bone graft, and screw breakage. In cases where infection does occur, the hardware must be removed.
