The Easyspine System is a posterior, noncervical pedicle and non-pedicle system 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 of the thoracic, lumbar and sacral spine:

Degenerative disc disease (defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies)
Spondylolisthesis
Trauma (i.e. fracture or dislocation)
Spinal stenosis
Deformities or curvatures (i.e. scoliosis, kyphosis, and/or lordosis)
Tumor
Pseudoarthrosis
Failed previous fusion

Device Description

The Easyspine System is designed to aid in the surgical correction of several types of spinal conditions. This system is intended only to provide stabilization during the development of a solid fusion with a bone graft. These implants are intended to be removed after the development of a solid fusion mass. Easyspine® consists of sacral and pedicle screws, cross-connections, rods of different rigidities and hooks. Specialized associated instrumentation is designed for implantation of these devices and for the distraction, compression or reduction of the lumbar and thoracic spine.

AI/ML Overview

The provided text describes a 510(k) premarket notification for the LDR Spine Easyspine® System. This is a medical device submission, and the content focuses on establishing substantial equivalence to a predicate device, primarily through mechanical performance data. It does not contain information about acceptance criteria, device performance metrics, or a study involving human readers or AI algorithms as requested in your prompt.

Specifically, the document states:

"Mechanical test results demonstrate that the proposed Easyspine System is substantially equivalent to the predicate device." (pg. 2, Section 8, "Non-Clinical Performance Data")

This indicates that the primary method of demonstrating equivalence was through mechanical testing, not through a clinical study with human readers or AI.

Therefore, I cannot provide the requested information about acceptance criteria, device performance, sample sizes, expert qualifications, adjudication methods, MRMC studies, or standalone algorithm performance. The device described is a physical implant (spinal system), not a diagnostic device or AI software that would typically have such performance metrics.

Dear Mr. Burrows:

Re:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA), You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies.

Regulation Number and Section

§ 888.3050 Spinal interlaminal fixation orthosis.

(a)
Identification. A spinal interlaminal fixation orthosis is a device intended to be implanted made of an alloy, such as stainless steel, that consists of various hooks and a posteriorly placed compression or distraction rod. The device is implanted, usually across three adjacent vertebrae, to straighten and immobilize the spine to allow bone grafts to unite and fuse the vertebrae together. The device is used primarily in the treatment of scoliosis (a lateral curvature of the spine), but it also may be used in the treatment of fracture or dislocation of the spine, grades 3 and 4 of spondylolisthesis (a dislocation of the spinal column), and lower back syndrome.(b)
Classification. Class II.
