Intended Use

When used as a posterior, non-pedicle system of the noncervical spine, the PLUS™ Pivot Link Universal System is indicated for: degenerative disc disease (discogenic back pain with degeneration of the disc confirmed by history and radiographic studies) spondylolisthesis fracture spinal stenosis deformities (i.e. scoliosis, kyphosis, lordosis) tumors failed previous fusion (pseudoarthrosis). The PLUS Pivot Link Universal System is also a pedicle screw system indicated for skeletally mature patients who: have severe spondylolisthesis (Grades 3 and 4) at the L5-S1 vertebra; receive fusions using autogenous bone graft only; have the device fixed or attached to the lumbar and sacral spine (L3 to sacrum); and have the device removed after the development of a solid fusion. In addition, the PLUS Pivot Link Universal System is a pedicle screw system 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 failed previous fusion (pseudoarthrosis).

Device Story

PLUS Pivot Link Universal System comprises spinal instrumentation including hooks, screws, rods, and connectors. Components assembled into constructs to provide immobilization and stabilization of thoracic, lumbar, and sacral spinal segments. Used by surgeons in clinical settings to treat spinal pathologies including deformities, fractures, and degenerative conditions. Device provides mechanical support as an adjunct to fusion. Benefits include stabilization of unstable spinal segments and correction of deformities.

Clinical Evidence

Bench testing only. No clinical data provided.

Technological Characteristics

Constructs consist of hooks, screws, rods, and connectors. Materials: stainless steel (ASTM F138, F1586), titanium alloy (ASTM F136), and commercially pure titanium (ASTM F67). Mechanical fixation system.

Indications for Use

Indicated for skeletally mature patients requiring spinal stabilization/immobilization for degenerative disc disease, spondylolisthesis, fractures, spinal stenosis, deformities (scoliosis, kyphosis, lordosis), tumors, dislocations, or pseudoarthrosis. Pedicle screw use restricted to L3-sacrum for severe L5-S1 spondylolisthesis (Grades 3-4) with autogenous bone graft and subsequent device removal.

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.
