When intended to promote fusion of the cervical spine and occipito-cervico-thoracic junction (occiput-T3), the Summit Occipito-Cervico-Thoracic (OCT) Spinal System is indicated for:
- ddd (neck pain of discogenic origin with degeneration of the disc as confirmed by patient history and radiographic studies)
- spondylolisthesis
- spinal stenosis
- fracture/dislocation
- atlantoaxial fracture with instability
- occipitocervical dislocation
- revision of previous cervical spine surgery
- tumors
The occipital bone screws are limited to occipital fixation only.
The use of the minipolyaxial screws is limited to placement in the upper thoracic spine (T1-T3) in treating thoracic conditions only. They are not intended to be placed in the cervical spine.
The Songer Cable System to be used with the Summit OCT Spinal System allows for wire/cable attachment to the posterior cervical spine.
The Summit OCT System can also be linked to the ISOLA, TiMX, Monarch and MOSS Miami Systems using the dual wedding band and axial connectors, and via dual diameter rods.
The Summit OCT Spinal System consists of plates, nuts, bone screws, rods, transverse rod connectors, cable connectors, dual wedding band and axial connectors, set screws, minipolyaxial screws and Songer Cables. For occipitocervicothoracic fusion, the transition rod is bent and cut to the appropriate length. The occipital plate is fixed to the occiput with bone screws and the transition rod is attached to the plate by a locking mechanism. This locking mechanism consists of a bolt and a washer which are free to rotate and translate along a slot in the occipital plates. The rod loads from the top and is fixed and locked into place with a mini outer nut. Sub-axially, cable connectors are fixed to the transition rod and attached to the spine via sublaminar cabling looped through the cable connectors. The end of the construct is stabilized with polyaxial screws and mini outer nuts to the upper thoracic spine, as required.
The Summit OCT System can also be linked to the ISOLA, TiMX. Monarch and MOSS Miami Systems using the dual wedding bands and axial connectors, and via dual diameter rods.
The provided text describes a medical device, the Summit Occipito-Cervico-Thoracic (OCT) Spinal System, and its submission for 510(k) clearance. It does not contain information about software, AI, or performance criteria typically associated with such technologies. Therefore, I cannot generate the requested table and study details.
The document focuses on the intended use, device description, and a general statement about "Biomechanical testing, including static and dynamic cantilever beam testing and axial slip testing" as performance data. This type of testing is standard for mechanical medical devices to establish their structural integrity and biocompatibility, not for assessing diagnostic accuracy or algorithmic performance.
Specifically, the document lacks information on:
- Acceptance Criteria for an AI/Software Device: There are no metrics like sensitivity, specificity, accuracy, F1-score, or any other performance thresholds typical for AI or software.
- Reported Device Performance of an AI/Software Device: No numerical results are provided that would correspond to the acceptance criteria.
- Sample Size for Test Set: There is no mention of a test set, only biomechanical testing performed on the physical device.
- Data Provenance: Not applicable as there's no data in the context of AI.
- Number of Experts & Qualifications for Ground Truth: Not applicable, as there's no algorithmic ground truth being established.
- Adjudication Method: Not applicable.
- MRMC Comparative Effectiveness Study: Not mentioned.
- Standalone Performance: Not applicable for a mechanical device.
- Type of Ground Truth: Not applicable for a mechanical device.
- Training Set Size and Ground Truth Establishment: Not applicable for a mechanical device.
The FDA letter confirms the device's substantial equivalence to predicate devices based on the information provided by the submitter, DePuy AcroMed, Inc. This 510(k) clearance process is for traditional medical devices, not for AI-enabled software.

§ 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.
