Intended Use

The Array® Spinal System is a non-cervical spinal fixation device intended for use as a pedicle screw fixation system, a posterior hook and sacral/iliac screw fixation system, or as an anterolateral fixation system. Pedicle screw fixation is limited to skeletally mature patients. The device is indicated for all of the following indications regardless of the intended use; degenerative disc disease (defined as discogenic back pain with degeneration of the disc confirmed by history and radiographic studies), spondylolisthesis, trauma, (i.e., fracture or dislocation), deformity or curvature (i.e., scoliosis, and/or lordosis), tumor, stenosis, pseudarthrosis, and failed previous fusion.

Device Story

The Array Spinal System is a non-cervical spinal fixation implant set. It functions as a mechanical stabilization system for the spine, utilizing pedicle screws, hooks, and sacral/iliac screws to provide structural support. The system is used by surgeons in an operating room setting to treat spinal pathologies such as degenerative disc disease, trauma, and deformity. The device provides rigid fixation to facilitate fusion or stabilization of the spinal column. This specific submission introduces a stainless steel material variant to the existing product line. The device is purely mechanical; it does not involve software, sensors, or electronic processing.

Clinical Evidence

Bench testing only. Mechanical performance testing was conducted to demonstrate that the system conforms to design specifications and meets requirements established by predicate devices.

Technological Characteristics

Non-cervical spinal fixation system consisting of pedicle screws, hooks, and sacral/iliac screws. Fabricated from stainless steel. Mechanical fixation device; no energy source, connectivity, or software components.

Indications for Use

Indicated for skeletally mature patients requiring non-cervical spinal fixation via pedicle screw, posterior hook, sacral/iliac screw, or anterolateral fixation. Conditions include degenerative disc disease, spondylolisthesis, trauma (fracture/dislocation), deformity (scoliosis, lordosis), tumor, stenosis, pseudarthrosis, and failed previous fusion.

Regulatory Classification

Identification

(1) Rigid pedicle screw systems are comprised of multiple components, made from a variety of materials that allow the surgeon to build an implant system to fit the patient's anatomical and physiological requirements. Such a spinal implant assembly consists of a combination of screws, longitudinal members (e.g., plates, rods including dual diameter rods, plate/rod combinations), transverse or cross connectors, and interconnection mechanisms (e.g., rod-to-rod connectors, offset connectors).(2) Semi-rigid systems are defined as systems that contain one or more of the following features (including but not limited to): Non-uniform longitudinal elements, or features that allow more motion or flexibility compared to rigid systems.

Special Controls

*Classification.* (1) Class II (special controls), when intended to provide immobilization and stabilization of spinal segments in skeletally mature patients as an adjunct to fusion in the treatment of the following acute and chronic instabilities or deformities of the thoracic, lumbar, and sacral spine: severe spondylolisthesis (grades 3 and 4) of the L5-S1 vertebra; degenerative spondylolisthesis with objective evidence of neurologic impairment; fracture; dislocation; scoliosis; kyphosis; spinal tumor; and failed previous fusion (pseudarthrosis). These pedicle screw spinal systems must comply with the following special controls:(i) Compliance with material standards; (ii) Compliance with mechanical testing standards; (iii) Compliance with biocompatibility standards; and (iv) Labeling that contains these two statements in addition to other appropriate labeling information: “Warning: The safety and effectiveness of pedicle screw spinal systems have been established only for spinal conditions with significant mechanical instability or deformity requiring fusion with instrumentation. These conditions are significant mechanical instability or deformity of the thoracic, lumbar, and sacral spine secondary to severe spondylolisthesis (grades 3 and 4) of the L5-S1 vertebra, degenerative spondylolisthesis with objective evidence of neurologic impairment, fracture, dislocation, scoliosis, kyphosis, spinal tumor, and failed previous fusion (pseudarthrosis). The safety and effectiveness of these devices for any other conditions are unknown.” “Precaution: The implantation of pedicle screw spinal systems should be performed only by experienced spinal surgeons with specific training in the use of this pedicle screw spinal system because this is a technically demanding procedure presenting a risk of serious injury to the patient.” (2) Class II (special controls), when a rigid pedicle screw system is intended to provide immobilization and stabilization of spinal segments in the thoracic, lumbar, and sacral spine as an adjunct to fusion in the treatment of degenerative disc disease and spondylolisthesis other than either severe spondylolisthesis (grades 3 and 4) at L5-S1 or degenerative spondylolisthesis with objective evidence of neurologic impairment. These pedicle screw systems must comply with the following special controls: (i) The design characteristics of the device, including engineering schematics, must ensure that the geometry and material composition are consistent with the intended use. (ii) Non-clinical performance testing must demonstrate the mechanical function and durability of the implant. (iii) Device components must be demonstrated to be biocompatible. (iv) Validation testing must demonstrate the cleanliness and sterility of, or the ability to clean and sterilize, the device components and device-specific instruments. (v) Labeling must include the following: (A) A clear description of the technological features of the device including identification of device materials and the principles of device operation; (B) Intended use and indications for use, including levels of fixation; (C) Identification of magnetic resonance (MR) compatibility status; (D) Cleaning and sterilization instructions for devices and instruments that are provided non-sterile to the end user; and (E) Detailed instructions of each surgical step, including device removal. (3) Class II (special controls), when a semi-rigid system is intended to provide immobilization and stabilization of spinal segments in the thoracic, lumbar, and sacral spine as an adjunct to fusion for any indication. In addition to complying with the special controls in paragraphs (b)(2)(i) through (v) of this section, these pedicle screw systems must comply with the following special controls: (i) Demonstration that clinical performance characteristics of the device support the intended use of the product, including assessment of fusion compared to a clinically acceptable fusion rate. (ii) Semi-rigid systems marketed prior to the effective date of this reclassification must submit an amendment to their previously cleared premarket notification (510(k)) demonstrating compliance with the special controls in paragraphs (b)(2)(i) through (v) and paragraph (b)(3)(i) of this section.

## TECHNOLOGICAL CHARACTERISTICS:

#### Performance Testing

Mechanical testing of the Array® Spinal System was conducted and demonstrates that the proposed system conforms to its design specifications. The design requirements were established based on those of the previously cleared predicate devices. The results of testing

{1}------------------------------------------------

conducted demonstrate that the worst case of the proposed system adequately meets the requirements established in design specifications for its mechanical performance.

### Substantial Equivalence

The Array® Spinal System is substantially equivalent to other legally marketed spinal fixation devices with respect to intended use and indications, technological characteristics, and basic principles of operation. This premarket notification is being submitted to reflect the addition of a spinal system fabricated from stainless steel. As demonstrated by mechanical testing, these technological differences do not present any new issues of safety or effectiveness.
