The F1 - Modular Pedicle Screw System (F1-MPS) is intended for posterior, noncervical pedicle fixation (T1-S1) 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 of the thoracic, lumbar, and sacral spine: severe spondylolisthesis (Grade 3 and 4) of the L5-S1 vertebra, degenerative spondylolisthesis with objective evidence of neurological impairment, spinal stenosis, fracture, dislocation, scoliosis or kyphotic deformities, spinal tumor, Schuermann’s disease, and failed previous fusion.
The F1-MPS is intended for posterior, noncervical pedicle fixation (T1-S1) to provide immobilization and stabilization of spinal segments in skeletally mature patients as an adjunct to fusion in the treatment of degenerative disc disease (back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies) and spondylolisthesis other than either severe spondylolisthesis (grades 3 and 4) at L5-S1 or degenerative spondylolisthesis with objective evidence of neurologic impairment.
The F1-MPS is also intended for posterior, non-cervical fixation in pediatric patients indicated as an adjunct to fusion to treat adolescent idiopathic scoliosis. The device is intended to be used with autograft and/or allograft.
Indications for use as stated in the FDA summary.
