PMT Expandable Cage (PMT EXP) is an integrated construct comprised of a CAVUX Cage-E and a single ALLY Screw-E.
PMT EXP is placed bilaterally through a posterior surgical and spans the facet interspace with points of fixation at each end of the construct.
PMT EXP is intended for temporary stabilization as an adjunct to single level posterior cervical fusion in skeletally mature patients. PMT EXP is only intended for use with a single level anterior cervical fusion at the same spinal level that utilizes FDA cleared/approved spine stabilization hardware for anterior cervical fusion procedures.
PMT EXP is indicated for the treatment of patients with cervical degenerative disc disease (DDD) with radiculopathy from C3-C7.
PMT EXP is indicated for use with autogenous and/or allogenic bone graft.
The PMT Expandable Cage (PMT EXP) is comprised of a CAVUX Cage-E and an ALLY Expansion Screw as an integrated construct, manufactured from medical grade titanium alloy, and supplied sterile for single use only. The components are provided with a pre-attached disposable delivery handle/inserter. The device achieves facet fixation by spanning the interspace with points of fixation at each end of the construct and provides temporary, bilateral, rigid fixation as an adjunct to fusion.
CORUS® Spinal System is recommended to access the site and perform posterior cervical fusion.
The threads of the Expansion Screw interface with the slot features of the Cage-E to increase the height of the Cage-E and promote strength of the total construct. The profile of the Cage-E provides contact area between the device and adjacent bony surfaces to fixate the segment. The Expansion Screw is made of 6AL 4V ELI Titanium (ASTM F136) and the washer is made of Commercially Pure Titanium Grade 2 (ASTM F67).
This FDA K-number document refers to a Class II medical device, the PMT Expandable Cage (PMT EXP), which is an integrated construct for temporary stabilization as an adjunct to single-level posterior cervical fusion. This document does not describe an AI/ML powered device, therefore no information about acceptance criteria or supporting studies related to AI/ML device performance is available.
The document primarily focuses on the device's substantial equivalency to predicate devices based on:
-
Device Description:
- The PMT Expandable Cage is made from medical-grade titanium alloy, supplied sterile for single use.
- It consists of a CAVUX Cage-E and an ALLY Expansion Screw.
- It is designed to achieve facet fixation by spanning the interspace with fixation points at each end, providing temporary, bilateral, rigid fixation.
-
Indications for Use:
- Temporary stabilization as an adjunct to single-level posterior cervical fusion in skeletally mature patients (C3-C7).
- Only for use with a single-level anterior cervical fusion at the same spinal level, utilizing FDA cleared/approved spine stabilization hardware.
- Treatment of cervical degenerative disc disease (DDD) with radiculopathy.
- Indicated for use with autogenous and/or allogenic bone graft.
Performance Data and Conclusion (for the physical device, not AI/ML):
- Mechanical Tests: Static and dynamic axial compression using a custom setup, and axial pullout testing per ASTM F543 were performed.
- Biomechanical Studies: Cadaver fatigue and kinematic studies were conducted to assess spinal stability and risk of device migration.
- Clinical Data: Clinical data were provided comparing the subject device to other cervical fusion techniques. This included radiographic and CT evaluations, peri-operative findings, patient-reported outcomes, and assessments of safety and effectiveness. The conclusion was that the clinical and radiographic data supported satisfactory clinical outcomes for the specified use.
Absence of AI/ML Specific Information:
The document does not mention any AI/ML components, algorithms, or software. Therefore, the requested information regarding AI/ML device acceptance criteria, performance tables, sample sizes for test/training sets, ground truth establishment, expert qualifications, or MRMC studies for AI/ML assistance is not applicable and not present in this submission.

Dear Mr. Liou:
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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reporting-
