• Product Code: KWP · Orthopedic
• Decision Date: Apr 17, 2008
• Decision: SESE
• Submission Type: Special
• Regulation: 21 CFR 888.3050
• Device Class: Class 2
• Attributes: Therapeutic

Intended Use

The intended use of the Sierra spinal system is to promote fusion of the cervical spine and occipito-cervico-thoracic junction (occiput-T3). The indications for use are as follows: - degenerative disc disease (DDD) as defined by neck pain of discogenic origin with degeneration of the disc confirmed by patient history and radiographic studies, - spondylolisthesis, - trauma (i.e., fracture or dislocation), - spinal stenosis, - atlantoaxial fracture with instability, - occipitocervical dislocation, - revision of previous cervical spine surgery, and/or - spinal tumor. The occipital bone screws are limited to occipital fixation only. The use of the polyaxial screws is limited to placement in the upper thoracic spine (T1-T3) in treating thoracic conditions only. They are not intended to be placed in the cervical spine.

Device Story

Sierra spinal system components (rod connectors, crossbars, set screws) facilitate spinal fusion; titanium alloy construction; non-sterile supply requiring sterilization before use. Used by surgeons in clinical settings for occipito-cervico-thoracic stabilization. Components integrate into existing Sierra system to provide mechanical fixation; supports bone fusion; aids in treating instability and degenerative conditions.

Clinical Evidence

No clinical data provided; substantial equivalence based on design and technological characteristics.

Technological Characteristics

Titanium alloy components (rod connectors, crossbars, set screws); non-sterile; requires sterilization; mechanical fixation system for occipito-cervico-thoracic spine.

Indications for Use

Indicated for patients requiring cervical spine and occipito-cervico-thoracic (occiput-T3) fusion due to degenerative disc disease, spondylolisthesis, trauma (fracture/dislocation), spinal stenosis, atlantoaxial fracture with instability, occipitocervical dislocation, revision surgery, or spinal tumor. Occipital screws limited to occipital fixation; polyaxial screws limited to T1-T3 thoracic conditions only (not for cervical spine).

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.

## Substantial equivalence claimed to:

The devices used for comparison in this summary are SeaSpine, Inc.'s Sierra Spinal System (K062934) and Interpore Cross International's Altius OCT System (K022048, K033961 and K043229).

The overall designs of the rod connectors, crossbars and set screws in this submission are substantially equivalent to the predicate devices.

## Description :

Rod connectors, crossbars and set screws are being added to the Sierra spinal system. All products are fabricated from titanium alloy. All products are supplied "NON-STERILE" and must be sterilized prior to use.

Intended use: (The statements of intended use are identical.)

The intended use of the Sierra spinal system is to promote fusion of the cervical spine and occipito-cervico-thoracic junction (occiput-T3). The indications for use are as follows:

- degenerative disc disease (DDD) as defined by neck pain of discogenic origin with ● degeneration of the disc confirmed by patient history and radiographic studies,
- spondylolisthesis. .
- trauma (i.e., fracture or dislocation), .
- . spinal stenosis.
- atlantoaxial fracture with instability, .
- occipitocervical dislocation, .

- revision of previous cervical spine surgery, and/or
- . spinal tumor.

The occipital bone screws are limited to occipital fixation only.

The use of the polyaxial screws is limited to placement in the upper thoracic spine (T1-T3) in treating thoracic conditions only. They are not intended to be placed in the cervical spine.

## Summary of technological characteristics:

The rod connectors, crossbars and set screws in this notification are components of ScaSpine's stand alone occipito-cervico-thoracic spinal fixation system called Sierra. The addition of the new devices has not altered the fundamental scientific technology of the previously cleared system. The devices in this submission have substantially equivalent technological characteristics to the predicate devices.
