Intended Use

When intended to promote fusion of the cervical spine and occipito-cervico-thoracic junction (Occiput-T3), the STRYKER Spine Oasys System is intended for: - Degenerative Disc Disease (as defined by neck and back pain of discogenic origin . with degeneration of the disc confirmed by history and radiographic studies) - . Spondylolisthesis - . Spinal Stenosis - . Fracture/Dislocation - Atlanto/axial fracture with instability . - Occipitocervical dislocation . - Revision of previous cervical spine surgery . - Tumors . When used with the occipital plate, the bone screws are limited to occipital fixation only. The bone screws are not intended to be used in the cervical spine. The use of the polyaxial screws is limited to placement in the upper thoracic spine (TI -T3). They are not intended to be placed in the cervical spine. The hooks and rods are also intended to provide stabilization to promote fusion following reduction of fracture/dislocation or trauma in the cervical/upper thoracic (C I-T3) spine. The Stryker Spine OASYS® System can be linked to the Xia® System, SR90D System and Xia® 4.5 Spinal System via the rod-to-rod connectors and transition rods. The Stryker Spine OASYS® System can also be linked to the polyaxial screws of Xia® II and Xia® 3 System via the saddle connector.

Device Story

OASYS System line extension introduces transition rods to existing spinal fixation hardware; components include rods, polyaxial screws, bone screws, hooks, and occiput plates. Fabricated from Titanium alloy, CP Titanium, and Vitallium. System provides stabilization to promote fusion in cervical/upper thoracic spine (C1-T3). Surgeons implant hardware to address instability or deformity. Device links to Stryker Xia, Xia 4.5, and SR90D systems via connectors. Mechanical stabilization supports bone healing; benefits patient by restoring spinal alignment and structural integrity.

Clinical Evidence

Bench testing only. Static and fatigue compression bending and static and fatigue torsion bending tests were performed in accordance with ASTM F1717 to verify mechanical integrity and equivalence to predicate devices.

Technological Characteristics

Spinal interlaminal fixation orthosis. Materials: Titanium alloy, CP Titanium, Vitallium. Components: rods, polyaxial screws, bone screws, hooks, occiput plates. Mechanical testing per ASTM F1717. Non-sterile. Connectivity: mechanical linkage to Xia/SR90D systems via connectors.

Indications for Use

Indicated for patients requiring cervical or occipito-cervico-thoracic (Occiput-T3) fusion due to degenerative disc disease, spondylolisthesis, spinal stenosis, fracture/dislocation, atlanto/axial fracture with instability, occipitocervical dislocation, revision surgery, or tumors. Bone screws limited to occipital fixation; polyaxial screws limited to T1-T3 thoracic 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.
