Intended Use

When used as a pedicle screw fixation system, the SHIRAZ Posterior System is intended for treatment of severe spondylolisthesis (Grades 3 and 4) at the fifth lumbar first sacral (L5-S1) vertebral joint in skeletally mature patients receiving fusion by mutogenous bone grafting having implants attached to the lumbar and sacral spine (L3 to sacrum) with removal of the implants after the attainment of a solid fusion. When used as a pedicle screw fixation system, the SHIRAZ Posterior System is also 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: degenerative spondylolisthesis with objective evidence of neurologic impairment, fracture, dislocation, scoliosis, kyphosis, spinal tumor, and failed previous fusion (pseudoarthrosis).

Device Story

Spine Next SHIRAZ Posterior System is a pedicle screw fixation system designed for surgical stabilization of thoracic, lumbar, and sacral spinal segments as an adjunct to fusion. System components include screws, rods, and connectors. Implants are placed by surgeons during spinal procedures to provide immobilization while bone graft fusion occurs; implants are intended for removal after solid fusion is achieved. Device provides mechanical support to the spine to treat deformities and instabilities.

Clinical Evidence

No clinical data. Bench testing only; biomechanical static and dynamic testing performed in accordance with ASTM F1717 and ASTM F1798.

Technological Characteristics

Materials: Titanium Alloy (Ti6Al4V) per ASTM F136/ISO 5832 or commercially pure Titanium (Grade 4) per ASTM F67/ISO 5832. Components: screws, rods, connectors, secondary sacral connectors. Mechanical fixation principle.

Indications for Use

Indicated for skeletally mature patients requiring spinal fusion. Conditions: severe spondylolisthesis (Grades 3-4, L5-S1), degenerative spondylolisthesis with neurologic impairment, fracture, dislocation, scoliosis, kyphosis, spinal tumor, and pseudoarthrosis. Used in thoracic, lumbar, and sacral spine.

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.
