Atlas Spine Project X Expandable Posterior Lumbar Interbody Spacers are intended for use in patients with degenerative disc disease (DDD) at one or two contiguous levels of the lumbosacral spine (L2-S1). DDD is defined as discogenic back pain with degeneration of the disc confirmed by history and radiographic studies. These patients should be skeletally mature and have had at least six (6) months of nonoperative treatment. In addition, these patients may have up to Grade 1 spondylolisthesis or retrolisthesis at the involved level(s).
Atlas Spine Project X Expandable Posterior Lumbar Interbody Spacers are to be filled with autogenous bone graft material. This device is intended to be used with supplemental fixation, such as the Apelo™ Pedicle Screw System.
Not Found
The provided FDA 510(k) clearance letter for the "Atlas Spine Project X Expandable Posterior Lumbar Interbody System" does not contain information on acceptance criteria or a study that proves the device meets specific performance criteria.
The letter is a regulatory document confirming that the device has been reviewed and found substantially equivalent to legally marketed predicate devices. It focuses on regulatory compliance, classification, and applicable regulations (such as Quality System regulations, UDI rules, and adverse event reporting).
Therefore, I cannot provide the requested information from the given input because the document does not contain details about:
- Acceptance criteria and reported device performance.
- Sample size, data provenance, number of experts, or adjudication methods for any test set.
- MRMC comparative effectiveness study results.
- Standalone performance studies.
- Type of ground truth used.
- Training set sample size or how its ground truth was established.
The letter mentions the "Indications for Use" for the device, detailing the patient population and conditions for which it is intended, but this is distinct from performance criteria and study results.
§ 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.
