Intended Use

When intended to promote fusion of the cervical spine and occipito-cervicothoracic junction (occiput-T3), the PROTEX™ CT Spinal System is indicated for: degenerative disc disease (as defined by neck pain of discogenic origin with degeneration of the disc confirmed by patient history and radiographic studies), spondylolisthesis, spinal stenosis, fracture, dislocation, atlanto/axial fracture with instability, occipitocervical dislocation, revision of previous cervical spine surgery, and tumors. The use of 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. Occipital bone screws are limited to occipital fixation; they are not intended for fixation of the posterior cervical spine. The PROTEX™ CT System can also be linked to titanium rod systems ranging in diameter from 3.7mm to 6.5mm, including the PROTEX™ System, using parallel connectors.

Device Story

PROTEX™ CT Cervicothoracic Spinal System; spinal fixation hardware including rods, polyaxial screws, hooks, locking caps, t-connectors, lateral connectors, and occipital clamps. Titanium alloy construction. Used by surgeons in clinical settings to stabilize and promote fusion of cervical spine and occipito-cervicothoracic junction. System allows linkage to other titanium rod systems (3.7mm-6.5mm) via parallel connectors. Provides mechanical stabilization to address degenerative conditions, fractures, and tumors. Output is rigid structural support for spinal segments.

Clinical Evidence

Bench testing only; no clinical data provided.

Technological Characteristics

Titanium alloy implants; includes rods, polyaxial screws, hooks, and various connectors. Designed for spinal fixation. No software or electronic components.

Indications for Use

Indicated for patients requiring fusion of the cervical spine and occipito-cervicothoracic junction (occiput-T3) due to degenerative disc disease, spondylolisthesis, spinal stenosis, fracture, dislocation, atlanto/axial fracture with instability, occipitocervical dislocation, revision surgery, or tumors. Polyaxial screws contraindicated for cervical spine; limited to T1-T3 thoracic conditions. Occipital screws limited to occipital fixation.

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.
