Read the full statement (236 words)
The Preference Pedicle Fixation System is intended to help provide immobilization and stabilization of spinal segments as an adjunct to fusion of the lumbar and/or sacral spine, specifically as follows:
When used as a pedicle screw fixation system of the non-cervical posterior spine in skeletally mature patients, the Preference Pedicle Fixation system is indicated for one or more of the following: (1) degenerative spondylolisthesis with objective evidence of neurologic impairment, (2) fracture, (3) dislocation, (4) spinal tumor, and/or (5) failed previous fusion (pseudarthrosis) and/or spinal deformities such as scoliosis, kyphosis or excessive lordosis.
In addition, when used as a pedicle screw fixation system, the Preference Pedicle Fixation System is indicated for skeletally mature patients: (a) having severe spondylolisthesis (Grades 3 and 4) of the fifth lumbar-first sacral (L5-S1) vertebral joint; (b) who are receiving fusions using autogenous bone graft only; (c) who are having the device fixed or attached to the lumbar and sacral spine (L3 and below); and (d) who are having the device removed after the development of a solid fusion mass.
When used as a posterior, non-cervical, non-pedicle screw fixation system, the Preference Pedicle Fixation System is intended for the following indications: (1) degenerative disc disease (as defined by back pain of discogenic origin with degeneration of the disc confirmed by patient history and radiographic studies), (2) spinal stenosis, (3) spondylolisthesis, (4) fracture, (5) pseudarthrosis, (6) tumor resection and/or (7) failed previous fusion.
Indications for use as stated in the FDA summary.
