The device description focuses on the mechanical components and materials of a pedicle screw system, with no mention of software, algorithms, or data processing that would indicate the use of AI/ML. The performance studies are mechanical tests, not related to algorithmic performance.
Yes.
The device is intended as an adjunct to fusion for various medical conditions like degenerative disc disease, trauma, spinal stenosis, and curvatures, which are therapeutic indications aimed at treating or alleviating disease or injury.
No
The M.U.S.T. pedicle screw system is described as a device for "stabilization and fusion of the lumbar and thoracic spine" and is "intended for posterior non-cervical pedicle fixation or anterolateral fixation." This indicates it is a therapeutic or reconstructive device, not one used for diagnosis.
No
The device description clearly outlines physical components made of Titanium alloy and CoCrMo, such as screws and rods, which are implanted into the spine. This indicates it is a hardware medical device, not software-only.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly describes a surgical implant system for spinal fixation and fusion. This is a therapeutic device used in vivo (within the body).
- Device Description: The description details the physical components of the system (screws, rods, set screws) and their materials. It describes a mechanical device for stabilizing the spine.
- Lack of IVD Characteristics: There is no mention of the device being used to examine specimens derived from the human body (like blood, urine, tissue, etc.) to provide information for diagnosis, monitoring, or compatibility testing.
IVD devices are used to perform tests in vitro (outside the body) on biological samples. This device is a surgical implant used in vivo.

Device Description
The M.U.S.T. pedicle screw system is intended to be used for the stabilization and the fusion of the lumbar and thoracic spine. The M.U.S.T. pedicle screw system is characterized by different sizes of screws and rods. The screws are fixed in the pedicle and the vertebrae. The rods act as a connector between the different screws to create a stable construct. The M.U.S.T. pedicle screw implants can be applied with the common surgical technique for posterior instrumentation.
The M.U.S.T. pedicle screw implants are made of Titanium alloy (Ti6Al4V ELI - ISO 5832-3, ASTM F136) and CoCrMo (ISO 5832-12, ASTM F 1537). The M.U.S.T. pedicle screw implants consist of either cannulated or non cannulated poly-axial pedicle screws. The screws are offered with a diameter between 4.5 and 7mm and a length between 20 and 90mm. The screw shaft is color anodized to simplify the identification of the screw diameter. The pedicle screw has a dual lead thread to simplify the screw insertion and reduce the number of turns. The threads are designed with a cylindrical diameter. The pedicle screw is connected by 5.5mm Titanium alloy (Ti6Al4V ELI - ISO 5832-3, ASTM F136) or CoCrMo (ISO 5832-12, ASTM F 1537) rods to create a stable construct. The rods are offered straight and pre bent. The pre bent rods have a curvature of 200mm. The construct is secured using a set screw made of CoCrMo (ISO 5832-12, ASTM F 1537). The pedicle screws, set screws and rods are available both in sterile and unsterile packaging.

§ 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 Mr. Gross:
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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to 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.
