Intended Use

When used as a pedicle screw fixation system of the non-cervical posterior spine in skeletally mature patients, the COLORADO 2™ Spinal System Spinal System is indicated for one or more of the following: (1) degenerative spondylolisthesis with objective evidence of neurologic impairment, (2) fracture, (3) dislocation, (4) scoliosis, (5) kyphosis, (6) spinal turnor, and/or (7) failed previous fusion (pseudarthrosis). In addition, when used as a pedicle screw fixation system, the COLORADO 2" Spinal System is also 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 COLORADO 2™ Spinal 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) spinal deformities (i.e., scoliosis, kyphosis, and/or lordosis), (5) fracture, (6) pseudarthrosis, (7) tumor resection, and/or (8) failed previous fusion. When used as an anterolateral thoracic/lumbar system, the COLORADO 2TM Spinal 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) spinal deformities (i.e., scoliosis, kyphosis, and/or lordosis), (5) fracture, (6) pseudarthrosis, (7) tumor resection, and/or (8) failed previous fusion.

Device Story

Spinal fixation system comprising rods, hooks, screws, and cross-connectors; components rigidly locked in tailor-made configurations for individual patient anatomy. Used in posterior non-cervical or anterolateral thoracic/lumbar procedures. Operates as mechanical stabilization construct; provides structural support to spine during fusion. Surgeon-implanted in clinical/OR setting. System allows connection to specific Medtronic spinal systems (TSRH, CD HORIZON, GDLH, TENOR) via axial rod connectors. Benefits patient by stabilizing spinal segments to facilitate fusion and correct deformities.

Clinical Evidence

No clinical data; bench testing only.

Technological Characteristics

Materials: medical grade stainless steel (ASTM F138, ISO 5832-1/9) or titanium/titanium alloy (ASTM F67, ISO 5832-3/2). Mechanical fixation system; modular components (rods, hooks, screws, connectors). 5.5mm and 6.35mm rod compatibility.

Indications for Use

Indicated for skeletally mature patients requiring non-cervical spinal fixation for degenerative spondylolisthesis, fracture, dislocation, scoliosis, kyphosis, spinal tumor, pseudarthrosis, degenerative disc disease, spinal stenosis, or tumor resection. Specific pedicle screw use for severe L5-S1 spondylolisthesis (Grades 3-4) with autogenous bone graft.

Regulatory Classification

Identification

A spinal interlaminal fixation orthosis is a device intended to be implanted made of an alloy, such as stainless steel, that consists of various hooks and a posteriorly placed compression or distraction rod. The device is implanted, usually across three adjacent vertebrae, to straighten and immobilize the spine to allow bone grafts to unite and fuse the vertebrae together. The device is used primarily in the treatment of scoliosis (a lateral curvature of the spine), but it also may be used in the treatment of fracture or dislocation of the spine, grades 3 and 4 of spondylolisthesis (a dislocation of the spinal column), and lower back syndrome.

#### III. Product Description

The COLORADO 2™ Spinal System consists of a variety of shapes and sizes of rods, hooks, screws, cross connectors, and connecting components. COLORADO 2 ™ implant components can be rigidly locked into a variety of configurations, with each construct being tailor-made for the individual case. COLORADO 2™ Spinal System implant components are fabricated from medical grade stainless steel described by such standards as ASTM F138 or ISO 5832-1 or ISO 5832-9. Alternatively, the entire system may be made out of medical grade titanium or titanium alloy described by such standards as ASTM F67 or ISO 5832-3 or 5832-2.

The COLORADO 2™ Spinal System can be connected to only 5.5mm rods of the TSRH® Spinal System, CD HORIZON® Spinal System, GDLH®, and the TENOR™ Spinal Systems through 5.5mm axial rod connectors (i.e., CD HORIZON® Domino, COLORADO 2™ Connector for Sacral and Illio-Sacral Plates, TSRH® Offset and Axial Plates, etc.). Components from other systems may not be combined with components of the COLORADO 2™ Spinal System. When used with the COLORADO 2™ Spinal System components, the components from the other systems may only be used for the COLORADO 2™ Spinal System indications.

#### IV. Indications

When used as a pedicle screw fixation system of the non-cervical posterior spine in skeletally mature patients, the COLORADO 2TM Spinal System Spinal System is indicated for one or more of the following: (1) degenerative spondylolisthesis with objective evidence of neurologic impairment, (2) fracture, (3) dislocation, (4) scoliosis, (5) kyphosis, (6) spinal turnor, and/or (7) failed previous fusion (pseudarthrosis).

In addition, when used as a pedicle screw fixation system, the COLORADO 2" Spinal System is also 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.
