The OsteoCentric Spine MIS Pedicle Fastener System is intended to provide immobilization of spinal segments in skeletally mature patients as an adjunct to fusion in the treatment of acute and chronic instabilities or deformities of the thoracic, lumbar, and sacral spine.
The OsteoCentric Spine MIS Pedicle Fastem is intended for noncervical pedicle fixation for the following indications: degenerative disc disease (defined as back pain of discogenic origins 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, pseudoarthrosis; and failed previous fusion in skeletally mature patients.
When used in a posterior percutaneous approach with MIS instrumentation, the OsteoCentric Spine MIS Pedicle Fastener System is intended for noncervical pedicle fixation for the following indications: degenerative disc disease (defined as back pain of discogenic origins 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); turnor, pseudoarthrosis; and failed previous fusion in skeletally mature patients.
The OsteoCentric Spine MIS Pedicle Fastemer System is a posterior fusion spinal fixation system which consists of non-sterile pedicle fasteners (Ø4.5 - 08.5, 25 - 180 mm), cannulated pedicle fasteners (05.5 - 08.5, 25 - 100 mm), reduction fasteners, extended tab implants, locking caps, and rods (05.5, 30 - 180 mm). The fasteners are used to attach the system components to the non-cervical spine and allows a surgeon to build an implant construct with the intent to stabilize the operative site during the fusion process.
The implant components are manufactured from titanium alloy (ASTM F136).
The provided text is a 510(k) Summary for the OsteoCentric Spine MIS Pedicle Fastener System. This document is a regulatory submission to the FDA, demonstrating "substantial equivalence" to a legally marketed predicate device, rather than a study proving the device meets specific performance acceptance criteria for a new AI/software medical device.
Therefore, the information required to answer your prompt, which focuses on acceptance criteria and a study proving an AI/software device's performance (including sample sizes, expert ground truth, adjudication methods, MRMC studies, standalone performance, training sets, etc.), is not present in the provided text.
The document states:
- "The OsteoCentric Spine MIS Pedicle Fastener System's components were previously cleared under predicate K151648. No additional performance data was submitted to demonstrate the substantial equivalence of the subject device to the predicate." (Page 5, Section VII. Performance Data)
This explicitly indicates that no new performance study was conducted or submitted for this specific 510(k) application (K221332) to demonstrate the device meets new acceptance criteria. Instead, it relies on the prior clearance of its components and its substantial equivalence to an existing predicate device (K151648) based on identical indications for use, materials, sterilization, and manufacturing methods.
In summary, based on the provided text, I cannot answer the questions about acceptance criteria, study details, sample sizes, expert involvement, or ground truth establishment because no such performance study was conducted or submitted for this device's 510(k) clearance.
§ 888.3070 Thoracolumbosacral pedicle screw system.
(a)
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.
(b)
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.
