KHEIRON@ Spinal Fixation System including patient specific K-ROD 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 thoracic, lumbar, and sacral spine: degenerative disc disease (defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies), degenerative spondylolisthesis with objective evidence of neurological impairment, fracture, dislocation, deformities or curvatures (i.e. scoliosis, kyphosis, and/or lordosis), spinal stenosis, spinal tumor, pseudarthrosis and failed previous fusion.

When used for posterior, non-cervical, pedicle screw fixation in pediatric patients, KHEIRON® Spinal Fixation System including patient specific K-ROD is indicated as an adjunct to fusion to treat progressive spinal deformities (i.e., scoliosis, kyphosis, or lordosis) including idiopathic scoliosis, neuromuscular scoliosis, and congenital scoliosis. Additionally, KHEIRON@ Spinal Fixation System including patient specific K-ROD is intended to treat pediatric patients diagnosed with spondylolisthesis/spondylolysis, fracture caused by tumor and/or trauma, pseudarthrosis, and/or failed previous fusion.

This system is intended to be used with autograft and/or allograft.

Pediatric pedicle screw fixation is limited to a posterior approach.

Patient specific K-ROD devices are compatible with NuVasive Reline System components that are only compatible with 05.5mm and/or 06.0mm rods as well as screws 04.5mm or larger and at least 25mm in length.

Patient specific K-ROD devices are compatible with Seaspine Mariner System components that are compatible with 05.5mm and/or 06.0mm rods as well as screws 04.5mm or larger and at least 25mm in length.

Patient specific K-ROD devices are compatible with VitalTM Spinal Fixation System components that are compatible with 05.5mm and/or 06.0mm rods as well as screws 04.0mm or larger and at least 20mm in length.
