Intended Use

The CD HORIZON® Spinal System with or without SEXTENT® instrumentation is intended for posterior, non-cervical fixation for the following indications: degenerative disc disease (defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies); spondylolisthesis; trauma (i.e., fracture or dislocation); spinal stenosis; curvatures (i.e., scoliosis, kyphosis and/or lordosis); tumor; pseudarthritis; and/or failed previous fusion. Except for hooks, when used as an anterolateral thoracic/lumbar system, the CD HORIZON® Spinal System may also be used for the same indications. With the exception of degenerative disc disease, the CD HORIZON LEGACY 3.5mm rods and the CD HORIZON® Spinal System PEEK rods and associated components may be used for the aforementioned indications in skeletally mature patients. The CD HORIZON® SPIRE Plate is a posterior, non-pedicle supplemental fixation device intended for use in the non-cervical spine (T1-S1). It is intended for plate fixation/attachment to spinous processes for the purpose of achieving supplemental fusion in the following conditions: degenerative disc disease (as previously defined); spondylolisthesis, trauma; and/or tumor. In order to achieve additional levels of fixation, the CD HORIZON® Spinal System rods may be connected to the VERTEX™ Reconstruction System with the VERTEX™ rod connector. Refer to the VERTEX™ Reconstruction System Package Insert for a list of the VERTEX™ indications of use.

Device Story

Spinal fixation system comprising rods, hooks, screws, plates, and connectors; used to build rigid spinal constructs for immobilization and stabilization as an adjunct to fusion. Components implanted by surgeons in clinical settings; construct configuration tailor-made for individual patient anatomy. System allows for posterior or anterolateral thoracic/lumbar fixation; can connect to VERTEX™ Reconstruction System for additional levels of fixation. Provides mechanical stabilization to the spine to facilitate fusion; benefits patients by addressing instability caused by trauma, degenerative disease, or deformity.

Clinical Evidence

No clinical data provided; substantial equivalence based on design and risk analysis (bench testing only).

Technological Characteristics

System components include rods, hooks, screws, plates, and connectors. Materials include PEEK and metallic alloys. Modular design allows for various construct configurations. Non-sterile; intended for surgical implantation.

Indications for Use

Indicated for posterior, non-cervical fixation in patients with degenerative disc disease, spondylolisthesis, trauma (fracture/dislocation), spinal stenosis, spinal curvatures (scoliosis, kyphosis, lordosis), tumor, pseudarthrosis, or failed previous fusion. Anterolateral thoracic/lumbar use permitted (excluding hooks). PEEK rods and 3.5mm rods indicated for skeletally mature patients (excluding degenerative disc disease). SPIRE plate indicated for supplemental fusion in T1-S1 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.

#### IV. Product Description

The CD HORIZON® Spinal System consists of a variety of rods, hooks, screws, CROSSLINK® plates, staples, and other connecting components used to build a spinal construct. Instrumentation is also available to facilitate implantation of the device components.

The CD HORIZON® Spinal System is intended to help provide immobilization and stabilization of spinal segments as an adjunct to fusion of the thoracic, lumbar, and/or sacral spine. The CD HORIZON® Spinal System implant components can be rigidly locked into a variety of configurations, with each construct being tailor-made for the individual case. If necessary, the CD HORIZON® Spinal System can be connected to the VERTEX™ Reconstruction System through a rod connector.

Certain implant components from other Medtronic Sofamor Danek spinal systems can be used with the CD HORIZON® Spinal System. These components include TSRH® rods, hooks, screws, plates, CROSSLINK® plates, connectors, staples and washers; GDLH® rods, hooks, connectors and CROSSLINK® bar and connectors; LIBERTY® rods and screws; DYNALOK PLUS® bolts; and Medtronic Sofamor Danek Multi-Axial rods and screws.

CD HORIZON® hooks are intended for posterior use only. CD HORIZON® staples and CD HORIZON® ECLIPSE® rods and screws are intended for anterior use only. However, for patients of smaller stature, CD HORIZON® 4.5mm rods and associated components may be used posteriorly.

The purpose of this 510(k) submission is to add modified screws and lateral connectors to the CD HORIZON® Spinal System.

#### V. Indications

The CD HORIZON® Spinal System with or without SEXTENT® instrumentation is intended for posterior, non-cervical fixation for the following indications: degenerative disc disease (defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies); spondylolisthesis; trauma (i.e., fracture or dislocation); spinal stenosis; curvatures (i.e., scoliosis, kyphosis and/or lordosis); tumor; pseudarthritis; and/or failed previous fusion.

Except for hooks, when used as an anterolateral thoracic/lumbar system, the CD HORIZON® Spinal System may also be used for the same indications.

With the exception of degenerative disc disease, the CD HORIZON LEGACY 3.5mm rods and the CD HORIZON® Spinal System PEEK rods and associated components may be used for the aforementioned indications in skeletally mature patients.

The CD HORIZON® SPIRE is a posterior, non-pedicle supplemental fixation device intended for use in the non-cervical spine (T1-S1). It is intended for plate fixation/attachment to spinous processes for the purpose of achieving supplemental fusion in the following conditions: degenerative disc disease (as previously defined); spondylolisthesis, trauma; and/or tumor.

In order to achieve additional levels of fixation, the CD HORIZON® Spinal System rods may be connected to the VERTEX™ Reconstruction System with the VERTEX™ rod connector. Refer to the VERTEX™ Reconstruction System Package Insert for a list of the VERTEX™ indications of use.

#### VI. Substantial Equivalence

Documentation, including a Risk Analysis, was provided which demonstrated the subject multi-axial screws and lateral connectors to be substantially equivalent to components cleared in earlier CD HORIZON® Spinal System applications (K042025 and K020709 respectively). The labeling is identical to that of the CD HORIZON® Spinal System cleared in K060203.
