The Altus Spine Titanium Interbody Fusion System is indicated for use with autogenous bone graft in skeletally mature patients with degenerative disc disease ("DDD") at one or two contiguous spinal levels from L2-S1. DDD is defined as discogenic back pain with degeneration of the disc confirmed by history and radiographic studies. These patients should have had six months of non-operative treatment. These DDD patients may have had a previous non-fusion spinal surgery at the involved spinal level(s), and may have up to Grade 1 spondylolisthesis or retrolisthesis at the involved level(s).
The Altus Spine Titanium Interbody Fusion System is to be combined with cleared supplemental fixation systems, such as the Altus Spine Pedicle Screw System.
The Altus Spine Titanium Interbody Fusion System implants are available in a variety of different shapes and sizes to suit the individual pathology and anatomical conditions of the patient.
The Altus Spine Titanium Interbody Fusion System implants are made of titanium alloy (Ti-6Al-4V) that conforms to ASTM F136.
The Altus Spine Titanium Interbody Fusion System has a hollow chamber to permit packing with autogenous bone graft to facilitate fusion. The superior and inferior surfaces of the construct have a pattern of teeth to provide increased stability and to help prevent movement of the device.
The provided text is a 510(k) premarket notification decision letter from the FDA for the Altus Spine Titanium Interbody Fusion System. It states that the device is substantially equivalent to legally marketed predicate devices.
The document discusses the mechanical properties and design equivalency, but it does not describe any clinical study or provide acceptance criteria related to device performance in a clinical setting (such as accuracy, sensitivity, specificity, etc.) for an AI/ML device.
Therefore, I cannot provide the requested information regarding acceptance criteria and the study proving device performance in the context of an AI/ML device, as this document pertains to a medical device for spinal fusion that does not appear to involve AI/ML.
Here's why some of the requested points are not applicable to the provided document:
- A table of acceptance criteria and the reported device performance: This document focuses on demonstrating substantial equivalence based on material and design, not clinical performance metrics for an AI/ML system.
- Sample size used for the test set and the data provenance: No clinical test set or data provenance is mentioned.
- Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable.
- Adjudication method: Not applicable.
- If a multi reader multi case (MRMC) comparative effectiveness study was done: Not applicable.
- If a standalone (i.e. algorithm only without human-in-the loop performance) was done: Not applicable.
- The type of ground truth used: Not applicable.
- The sample size for the training set: Not applicable.
- How the ground truth for the training set was established: Not applicable.
The document states that "Engineering analysis was presented to demonstrate that the Altus Spine Titanium Interbody Fusion System does not present a new worst case in performance and is substantially equivalent to the predicates." This refers to mechanical integrity and design equivalence, not AI/ML performance.
§ 888.3080 Intervertebral body fusion device.
(a)
Identification. An intervertebral body fusion device is an implanted single or multiple component spinal device made from a variety of materials, including titanium and polymers. The device is inserted into the intervertebral body space of the cervical or lumbosacral spine, and is intended for intervertebral body fusion.(b)
Classification. (1) Class II (special controls) for intervertebral body fusion devices that contain bone grafting material. The special control is the FDA guidance document entitled “Class II Special Controls Guidance Document: Intervertebral Body Fusion Device.” See § 888.1(e) for the availability of this guidance document.(2) Class III (premarket approval) for intervertebral body fusion devices that include any therapeutic biologic (e.g., bone morphogenic protein). Intervertebral body fusion devices that contain any therapeutic biologic require premarket approval.
(c)
Date premarket approval application (PMA) or notice of product development protocol (PDP) is required. Devices described in paragraph (b)(2) of this section shall have an approved PMA or a declared completed PDP in effect before being placed in commercial distribution.
