What is it indicated for?
The Patriot Spinal Fixation System, when used in the non-cervical posterior spine (T1 to S1), is intended to provide immobilization and stabilization of spinal segments in skeletally mature patients as an adjunct to fusion in the treatment of the following acute and chronic instabilities or deformities: degenerative spondylolisthesis with objective evidence of neurologic impairment, fracture, dislocation, deformities or curvatures (i.e., scoliosis…
Read the full statement (108 words)
The Patriot Spinal Fixation System, when used in the non-cervical posterior spine (T1 to S1), is intended to provide immobilization and stabilization of spinal segments in skeletally mature patients as an adjunct to fusion in the treatment of the following acute and chronic instabilities or deformities: degenerative spondylolisthesis with objective evidence of neurologic impairment, fracture, dislocation, deformities or curvatures (i.e., scoliosis, kyphosis, and/or lordosis), spinal stenosis, tumor, pseudoarthrosis, and failed previous fusion.
In addition, when used placed between L5 and S1, the Patriot Spinal Fixation System is indicated for the treatment of severe spondylolisthesis (Grade 3 and 4) in skeletally mature patients receiving fusion with autologous bone graft.
