Indications for Use

Blackstone Spinal Fixation System is intended for non-cervical use in the spine. The Blackstone Spinal Fixation System, when used for pedicle screw fixation, is intended only for patients: a) Having severe spondylolisthesis (Grades 3 and 4) at the L5-S1 joint; b) Who are receiving fusion using autogenous bone graft only; c) Who are having the device fixed or attached to the lumbar and sacral spine (L3 and below); and d) Who are having the device removed after the development of a solid fusion mass. The Blackstone Spinal Fixation System, when used as a pedicle screw system in skeletally mature patients, is intended to provide immobilization and stabilization of spinal segments, as an adjunct to fusion, in treatment of the following acute and chronic instabilities or deformities of the thoracic, lumbar and sacral spine: a) Degenerative spondylolisthesis with objective evidence of neurologic impairment; b) Fracture; c) Dislocation; d) Scoliosis; e) Kyphosis; f) Spinal tumor; and g) Failed previous fusion (pseudarthrosis). The Blackstone Spinal Fixation System, when used for anterolateral non-pedicle fixation, is intended for the following indications: a) Degenerative disc disease (as defined as back pain of discogenic origin with degenerative disc confirmed by patient history and radiographic studies); b) Spinal stenosis; c) Spondylolisthesis; d) Spinal deformities (i.e., scoliosis, kyphosis, and/or lordosis); e) Pseudarthrosis; f) Tumor; g) Trauma (i.e., fracture or dislocation); h) Previous failed fusion. The Blackstone Spinal Fixation System, when used for posterior non-pedicle fixation, is intended for the following indications: a) Degenerative disc disease (as defined as back pain of discogenic origin with degenerative disc confirmed by patient history and radiographic studies); b) Spinal stenosis; c) Spondylolisthesis; d) Spinal deformities (i.e., scoliosis, kyphosis, and/or lordosis); e) Pseudarthrosis; f) Tumor; g) Trauma (i.e., fracture or dislocation); h) Previous failed fusion.

Device Story

Blackstone Spinal Fixation System Posterior Hooks are titanium alloy components; adjunct to existing spinal fixation system (screws/rods). Used by surgeons in clinical settings to build spinal implant constructs for immobilization/stabilization during fusion procedures. Components are non-sterile, single-use; fully interchangeable with previously cleared Blackstone system components. Provides mechanical support to spinal segments; aids in fusion development; intended for removal after solid fusion mass formation.

Clinical Evidence

No clinical data provided; substantial equivalence based on design and intended use comparison to predicate device.

Technological Characteristics

Titanium alloy; non-sterile, single-use components; posterior hook form factor; mechanical fixation; manual surgical instrumentation.

Indications for Use

Indicated for skeletally mature patients requiring spinal immobilization/stabilization as an adjunct to fusion for thoracic, lumbar, and sacral spine instabilities/deformities including degenerative spondylolisthesis, fractures, dislocations, scoliosis, kyphosis, spinal tumors, pseudarthrosis, spinal stenosis, and degenerative disc disease. Specific pedicle screw use restricted to severe L5-S1 spondylolisthesis (Grades 3-4) with autogenous bone graft.

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.
