Intended Use
The Xia Spinal System and the Xia Stainless Steel System are intended for use in the noncervical spine. When used as a pedicle screw fixation system, the Xia Spine System and Xia Stainless Steel Systems are intended for patients: (a) having severe spondylolisthesis (Grades 3 and 4) at the fifth lumbar - first sacral (L5-S1) vertebral joint; (b) who are receiving fusions using autogenous bone graft only; (c) who are having the device fixed or attached to the lumbar and sacral spine; and (d) who are having the device removed after the development of a solid fusion mass. When used as a pedicle screw fixation system, the Xia Spinal System and Xia Stainless Steel Systems are also 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: degenerative spondylolisthesis with objective evidence of neurologic impairment, fracture, dislocation, scoliosis, kyphosis, spinal tumor, and failed previous fusion (pseudarthrosis). When used as an anterior screw fixation system or a posterior hook and sacral/iliac screw fixation system, the Xia Spinal System and Xia Stainless Steel Systems are indicated for patients with degenerative disc disease which is defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies, spondylolisthesis, fracture, spinal stenosis, spinal deformities such as scoliosis, lordosis, tumor, pseudoarthrosis or revision of failed fusion attempts.

No
The summary describes a spinal fixation system made of mechanical components (screws, rods, hooks, etc.) and does not mention any software, algorithms, or AI/ML capabilities.

Yes
The device is described as an "adjunct to fusion" in the treatment of various spinal instabilities and deformities, such as spondylolisthesis, fracture, and scoliosis, indicating a therapeutic purpose to alleviate or treat a medical condition.

No

This device, the Xia Spinal System and Xia Stainless Steel System, is described as a fixation system for the spine used in surgical procedures for various spinal conditions, such as spondylolisthesis, fractures, and scoliosis. Its purpose is to provide immobilization and stabilization, not to diagnose medical conditions.

No

The device description explicitly lists physical components like screws, hooks, blockers, rods, and connectors, indicating it is a hardware-based medical device.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use clearly describes the device as a spinal fixation system used in surgical procedures to provide immobilization and stabilization of spinal segments. This is a therapeutic and structural function within the body.
  • Device Description: The device description details components like screws, hooks, rods, and connectors, which are all physical implants used in surgery.
  • Lack of IVD Characteristics: There is no mention of the device being used to examine specimens derived from the human body (like blood, tissue, etc.) to provide information for diagnosis, monitoring, or compatibility testing.

IVD devices are used in vitro (outside the body) to analyze biological samples. This device is used in vivo (inside the body) as a surgical implant.

§ 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.

Dear Ms. Ariemma:

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 vour 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.
