When intended to promote fusion of the cervical spine and the thoracic spine, (CI-T3), the VERTEX™ Reconstruction System is indicated for the following:
DDD (neck pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies), spondylolisthesis, spinal stenosis, fracture, dislocation, failed previous fusion and/or tumors.
Hooks and Rods
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 (C1-T3) spine.
Screws/Connectors
The use of screws (3.5mm and 4.0mm cancellous, and 4.0mm cortical) is limited to placement in T1-T3 in treating thoracic conditions only. The screws are not intended to be placed in the cervical spine.
Titanium ATLAS™ Cable System to be used with the VERTEX™ Reconstruction System allows for cable attachment to the posterior cervical or thoracic spine.
The VERTEX™ Reconstruction System is a posterior system, which consists of a variety of shapes and sizes of rods, hooks, screws, multi-axial screws, and connecting components, which can be rigidly locked to the rod in a variety of configurations, with each construct being tailormade for the individual case. Titanium ATLAS™ cable may be used with this system at the surgeon's discretion.
The VERTEX™ Reconstruction System is fabricated from medical grade titanium or titanium alloy described by such standards as ASTM F67 or ASTM F136 or ISO 5832-3 or 5832-2. The VERTEX™ Reconstruction System also includes a retaining ring for the multi-axial screw made of Shape Memory Alloy (Nitinol - NiTi) as described by ASTM F2063. Shape Memory Alloy is compatible with titanium alloy implants only. Do not use with stainless steel. Medtronic Sofamor Danek expressly warrants that these devices are fabricated from one of the foregoing material specifications. No other warranties, express or implied, are made. Implied warranties of merchantability and fitness for a particular purpose or use are specifically excluded. See the MSD Catalog for further information about warranties and limitations of liability. Never use stainless steel and titanium implant components in the same construct.
The purpose of this submission was to add a CROSSLINK® Clip, a CROSSLINK® Bar and a modified laminar hook to the system.
The provided text is a 510(k) summary for the VERTEX™ Reconstruction System. It describes the device, its indications for use, and states that it was found to be substantially equivalent to itself (meaning it's an update to an already cleared device).
However, this document does not contain any information about acceptance criteria or a study that proves the device meets specific acceptance criteria. It is a regulatory submission for premarket notification, focusing on demonstrating substantial equivalence to a predicate device, rather than providing performance study results against predefined acceptance criteria for a new AI/software device.
Therefore, I cannot populate the requested table and study details based on the provided text. The questions posed are typically relevant for AI/ML-driven or software-based medical devices where performance metrics (sensitivity, specificity, accuracy, etc.) are crucial for demonstrating safety and effectiveness. The VERTEX™ Reconstruction System is a physical implantable device.
§ 888.3050 Spinal interlaminal fixation orthosis.
(a)
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.(b)
Classification. Class II.
