## Indications for use
The SmartLoc TM is a spinal fixation system intended to provide immobilization and stabilization of thoracic, lumbar, and sacral spinal segments as an adjunct to fusion. When used as posterior, pedicle screw fixation, the system is intended for the treatment of severe spondylolisthesis (grades 3 and 4) of the L_5-S1 vertebra in skeletally mature patients. In addition, when used as a pedicle screw fixation system in the non-cervical posterior spine (Ti to S2), the system is intended for the treatment of the following acute and chronic instabilities or deformities: degenerative spondylolisthesis with objective evidence of neurologic impairment, fracture, dislocation, spinal stenosis, scoliosis, kylphosis, lordosis, spinal tumor, pseudarthrosis and failed previous fusion in skeletally mature patients. When used as a posterior, non-cervical, hook and/or sacral/iliac fixation system (i.e., nonpedicle screw), the SmarLocTM is intended for the treatment of the following acute and chronic instabilities or deformities: degenerative disc disease (as conformed by patient history and radiographic studies), spondylolisthesis, fracture, dislocation, scoliosis, kyphosis, lordosis, spinal stenosis, spinal tumor, pseudarthrosis and failed previous fusion.
