Read the full statement (220 words)
LnK Spinal Fixation System is non-cervical spinal fixation devices intended for use as posterior pedicle screw fixation
system T1-S2/ilium), or as an anterolateral fixation system (T8-L5). All components in the system are limited to
skeletally mature patients. These devices are indicated as an adjunct to fusion for all of the following indications
regardless of the intended use: degenerative dis disease (defined as discogenic back pain with degeneration of the disc
confirmed by history and radiographic studies); spondylolisthesis; trauma (i.e., fracture or dislocation); deformities or
curvatures (i.e., scoliosis, kyphosis, and/or lordosis); tumor; stenosis; and failed previous fusion (pseudoarthrosis).
The LnK Spinal Fixation 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.
In addition, the LnK Spinal Fixation System 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 of the thoracic, lumbar and sacral spine: degenerative spondylolisthesis with objective evidence of
neurological impairment, fracture, dislocation, scoliosis, kyphosis, spinal tumor, and failed previous fusion
(pseudoarthrosis).
Indications for use as stated in the FDA summary.
