Intended Use

As a posterior, non-pedicle screw system of the T4-S2 spine, the Osteonics® Spinal System Rod/Plate System and Techtonix™ System are indicated for: Long and short curve scoliosis Vertebral fracture or dislocation Spondylolisthesis Begenerative disc disease (defined as back pain of discogneic origin with degeneration of the disc confirmed by history and radiographic studies) Previously failed fusion Spinal tumor Pedicular Use: When used as a pedicle screw fixation system of the non-cervical posterior spine in skeletally mature patients, the Osteonics Spinal System Rod/Plate System and Techtonix "M System are indicated for one or more of the following: degenerative spondylolisthesis with objective evidence of neurological impairment, fracture, dislocation, scoliosis, kyphosis, spinal tumor, and failed previous fusion (pseudoarthrosis). In addition, the Osteonics® Spinal System Rod/Plate System and Techtonix™ System are indicated for pedicle screw fixation in skeletally mature patients with severe spondylolisthesis (Grades 3 and 4) at the L5-S1 joint, having fusions with autogenous bone graft, having the device fixed or attached to the lumbar and sacral spine (with pedicle placement at L3 and below) with removal of the implants after the development of a solid fusion mass.

Device Story

Techtonix™ System is a low-profile posterior plate system; line extension to Osteonics® Spinal System Rod/Plate System. Comprised of anatomically shaped titanium alloy plates, bone screws, and blockers. Used by surgeons in clinical settings for spinal fixation. Components provide structural support to stabilize spine during fusion procedures. Mechanical properties verified via bench testing to ensure equivalence to predicate. Non-sterile delivery.

Clinical Evidence

Bench testing only. No clinical data presented.

Technological Characteristics

Titanium alloy (ASTM F-136, ISO 5832-3). Low-profile posterior plate system. Components include anatomical plates, bone screws, and blockers. Non-sterile.

Indications for Use

Indicated for T4-S2 posterior non-pedicle fixation or non-cervical pedicle screw fixation in skeletally mature patients. Conditions include scoliosis, vertebral fracture/dislocation, spondylolisthesis, degenerative disc disease, failed fusion, kyphosis, and spinal tumor. Specific indication for severe spondylolisthesis (Grades 3-4) at L5-S1 with autogenous bone graft.

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.

### Predicate Device Identification

The features of the Techtonix " System are substantially equivalent to the features of the Osteonics Spinal System Rod/ Plate System (RPS) which was determined substantially equivalent via 510(k) K991055.

### Description of Device Modification

This submission is intended to expand the Osteonics® Spinal System Rod/ Plate System product line by adding the Techtonix™ System, a low profile posterior plate system. Similar to its predicate device, the Techtonix™ System is comprised of anatomical shaped plates and bone screws available in a variety of lengths, and blockers (which tighten the bone screws to the plates). The components of the subject device are fabricated from Titanium alloy as described in ASTM F-136 and ISO 5832-3. The Techtonix™ System will be provided non-sterile.
