The Wiltse System Is a pedicle screw system indicated for the treatment of severe spondylolisthesis (Grades 3 and 4) of the L5-S1 vertebra in skeletally mature patients receiving fusion by autogenous bone graft having implants attached to the lumbar and sacral spine (L3 to sacrum) with removal of the implants after the attainment of a solid fusion.

The Wiltse System is also intended for anterolateral screw fixation of the noncervical spine. Indications for this system include treatment of cases of spondylolisthesis, fracture, spinal stenosis, deformittes (including scollosis, kyphosis, and lordosis), tumor, pseudoarthrosis, and revision of failed previous fusion surgery. Other indications include degenerative lumbar scollosis, degenerative spondylolisthesis, and in spinal stenosis, where decompression is required.
