Xenco Medical Lumbar Interbody System devices are intended for spinal fusion procedures at one or two contiguous levels (L2-S1) in skeletally mature patients with degenerative disc disease (DDD). DDD is defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies. DDD patients may also have up to Grade 1 spondylolisthesis or retrolisthesis at the involved levels. These patients may have had a previous nonfusion spinal surgery at the involved spinal level(s). The device is intended to be used with supplemental fixation systems that have been cleared for use in the lumbrosacral spine (e.g. posterior pedicle screw and rod systems, anterior plate systems, and anterior screw and rod systems). Hyperlordotic interbody devices (>=20° lordosis) must be used with at least anterior supplemental fixation. The device is intended to be used with autogenous bone graft. Patients must have undergone a regimen of at least six months of non-operative treatment prior to being treated with the Xenco Medical device.

I am sorry, but the provided text is a government document (FDA 510(k) clearance letter and Indications for Use) for a medical device called the "Xenco Medical Lumbar Interbody System." This type of document does not contain the information you are requesting about acceptance criteria from a study, device performance in terms of metrics like sensitivity/specificity, or details about the study design (sample size, experts, ground truth, MRMC studies, etc.).
This document focuses on:
- The FDA's determination of substantial equivalence to a legally marketed predicate device.
- The intended use and indications for the device.
- Regulatory class and product code.
- General controls and applicable regulations.
Therefore, I cannot provide the requested information based on the text provided.
§ 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.
