Intended Use

The Range Spinal System is comprised of the Denali Deformity and Mesa spinal systems all of which are cleared for the following indications: Non-cervical spinal fixation devices intended for posterior, non-pedicle stabilization as an adjunct to fusion for the following indications: degenerative disc disease (DDD) (defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies ); spondylolisthesis; trauma ( i.e. fracture or dislocation ); spinal stenosis; curvatures ( i.e. scoliosis, kyphosis; and/or lordosis); tumor; pseudoarthrosis; and failed previous fusion. Non-cervical pedicle screw fixation devices for stabilization as an adjunct to fusion for the following indications: trauma ( i.e. fracture or dislocation ); spinal stenosis; curvatures (i.e. scoliosis; and/or lordosis); turnor; pseudoarthrosis; and failed previous fusion. It is also indicated for the treatment of severe spondylolisthesis ( grades 3 and 4 ) of the LS-S1 vertebra in skeletally mature patients receiving fusion by autogenous bone graft having implants attached to the lumbar and sacral spine ( 1.3 to sacrum) with removal of the implants after the attainment of a solid fusion.

Device Story

Mesa Spinal System is a top-loading, posterior spinal fixation system; components include pedicle screws, rods, hooks, and transverse connectors. Used by surgeons in clinical settings to provide immobilization of thoracic, lumbar, and sacral spinal segments as an adjunct to fusion. System components are available in various sizes to match patient anatomy. Device provides mechanical stabilization to facilitate spinal fusion; implants are intended for removal after solid fusion is attained.

Clinical Evidence

Bench testing only. Biomechanical testing performed per ASTM F1717 compared the device to predicate and other currently marketed systems; results showed performance equal to or better than these systems.

Technological Characteristics

Manufactured from Ti6Al-4V ELI alloy per ASTM and ISO standards. System is a top-loading, posterior spinal fixation construct consisting of pedicle screws, rods, hooks, and transverse connectors. Mechanical immobilization principle.

Indications for Use

Indicated for non-cervical spinal stabilization as an adjunct to fusion in patients with degenerative disc disease, spondylolisthesis, trauma (fracture/dislocation), spinal stenosis, spinal curvatures (scoliosis, kyphosis, lordosis), tumor, pseudoarthrosis, or failed previous fusion. Specifically indicated for severe spondylolisthesis (grades 3-4) at L5-S1 in skeletally mature patients using autogenous bone graft with implants attached to lumbar/sacral spine (L3 to sacrum).

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.

## 3. Predicate or legally marketed devices which are substantially equivalent :

- Mesa Spine System ( K2M, Inc. ) .
#### 4. Description of the device :

The Mesa Spine System is a top-loading, multiple component, posterior spinal fixation system which consists of pedicle screws, rods, hooks, and transverse connectors. All of the components are available in a variety of sizes to match more closely the patient's anatomy.

Materials: The devices are manufactured from Ti6Al-4V ELI alloy per ASTM and ISO standards.

Function: The system functions as an adjunct to fusion to provide immobilization of spinal segments of the thoracic, lumbar and / or sacral spine.

#### 5. Intended Use:

The Range Spinal System is comprised of the Denali Deformity and Mesa spinal systems all of which are cleared for the following indications:

Non-cervical spinal fixation devices intended for posterior, non-pedicle stabilization as an adjunct to fusion for the following indications: degenerative disc disease (DDD) (defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies ); spondylolisthesis; trauma ( i.e. fracture or dislocation ); spinal stenosis; curvatures ( i.e. scoliosis, kyphosis; and/or lordosis); tumor; pseudoarthrosis; and failed previous fusion.

Non-cervical pedicle screw fixation devices for stabilization as an adjunct to fusion for the following indications: trauma ( i.e. fracture or dislocation ); spinal stenosis; curvatures (i.e. scoliosis; and/or lordosis); turnor; pseudoarthrosis; and failed previous fusion. It is also indicated for the treatment of severe spondylolisthesis ( grades 3 and 4 ) of the LS-S1 vertebra in skeletally mature patients receiving fusion by autogenous bone graft having implants attached to the lumbar and sacral spine ( 1.3 to sacrum) with removal of the implants after the attainment of a solid fusion.

## 6. Comparison of the technological characteristics of the device to predicate and legally marketed devices :

The Mesa Spine System was biomechanically tested and compared to predicate systems and other currently marketed systems and performed equal to or better than these systems in ASTM testing to F1717. The design features and sizing of the components were also compared and the Mesa System found to be substantially the same as these systems. It is manufactured from the same FDA recognized materials and is indicated for the same intended uses as these systems. There are no significant differences between the Mesa Spinal Systems currently being marketed which would adversely affect the use of the product. It is substantially equivalent to these other devices in design, function, material and intended use.

Dear Mr. Woods:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food. Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
