DDD is defined as discogenic pain with degeneration of the disc confirmed by patient history and radiographic studies. This device is to be used in patients who have had six weeks of non-operative treatment. The MOD-C device is to be used with supplemental fixation, such as a cervical plate system. The MOD-C device is intended to be used with autogenous and/or allogeneic bone graft composed of cancellous and/or corticocancellous bone graft to facilitate fusion and is to be implanted via an anterior approach. # SUBJECT DEVICE DESCRIPTION MOD-C implants have a rounded, rectangular footprint with overall dimensions of 16 mm (medial-lateral) x 12 mm (anterior-posterior), with heights ranging from 5 mm to 12 mm in 1 mm increments. The implants are provided in each height with endplates that are parallel or with endplates having 7° of lordosis. To allow for placement of autogenous bone graft, MOD-C implants have two hollow chambers, open to the superior and inferior surfaces, each with a rounded rectangular shape (footprint). MOD-C implants are manufactured from a composite of an acrylic polymer and synthetic beta-tricalcium phosphate/hydroxyapatite (β-TCP/HA). The acrylic conforms to ASTM F3087, the synthetic β-TCP conforms to ASTM F1088, and the HA conforms to ASTM F1185. MOD-C implants are provided sterile by gamma irradiation for single patient use. # PERFORMANCE DATA Non-clinical data submitted to demonstrate substantial equivalence included: - sterilization gamma irradiation sterilization validation to a sterility assurance level of 10⁻⁶ by selecting and substantiating a 25 kGy dose using method VDmax25, according to ISO 11137-1 and ISO 11137-2; bacterial endotoxin testing including Limulus amebocyte lysate (LAL) test according to USP <85> to demonstrate that all sterile product meets a limit of < 20 EU/device; - reprocessing validation for the device-specific instruments according to AAMI TIR12 and AAMI TIR30; - moist heat sterilization for the device-specific instruments, validated to a sterility assurance level of 10⁻⁶ by the overkill method according to ANSI/AAMI/ISO 17665-1 and ANSI/AAMI ST79; - shelf life testing of samples after accelerated aging to the equivalent of one (1) year of real time aging according to ASTM F1980, with testing of the packaging sterile barrier and analysis of the implant devices; - biocompatibility testing according to ISO 10993-5, ISO 10993-10, ISO 10993-23, ISO 10993-11, ISO 10993-3, ISO 10993-18, and a toxicological risk assessment according to ISO 10993-17; - static and dynamic axial compression, static and dynamic compression shear, and static and dynamic torsion per ASTM F2077, subsidence per ASTM F2267, and expulsion testing; and - animal studies using a standardized osseointegration model in cortical and cancellous sites comparing the subject device material to PEEK and titanium alloy implants after time periods of 3, 6, 12, and 26 weeks. No clinical data were included in this submission. # EQUIVALENCE TO MARKETED DEVICES The Indications for Use Statement for the subject device is substantially equivalent to that of the predicate devices. All are indicated for single-level fusion in the cervical spine from C2 to T1 for patients with degenerative disc disease, who have had an adequate duration (6 weeks) of non-operative treatment prior to treatment with the device. The subject device and predicate devices all are indicated for use with supplemental cervical fixation. Slight differences in the specific language among the Indications for Use Statements do not change the intended use or impact the substantial equivalence of the Indications for Use Statements. The additional predicate device K142264 has additional indications for use in the lumbar spine, which does not affect the indications for use in the cervical spine. The design and overall range of dimensions of subject device implants are similar to those of the predicate devices. The superior and inferior surfaces of subject device and predicate devices are serrated (transverse ridges or teeth) and {6} K242303 Page 3 of 3 designed to help stabilize the device and resist unwanted intraoperative and postoperative migration. Similarly, the designs of the subject device and predicate devices include a hollow architecture with superior and inferior openings that together enable placement of autogenous bone graft for the purpose of achieving a solid fusion mass with the adjacent vertebral body endplates. The range of overall dimensions (medial-lateral width, anterior-posterior depth) and heights of the subject device are substantially equivalent to those of the predicate devices. The footprint (implant cross-sectional area), volume available for bone graft, and lordotic angles of the subject device are substantially equivalent to the primary predicate device. Mechanical testing performed according to ASTM F2077, ASTM F2266, and expulsion testing demonstrated the subject device to be substantially equivalent to the primary predicate device or to published literature. ## CONCLUSION Any differences in the technological characteristics between the subject device and predicate devices do not raise different questions of safety or effectiveness. The data included in this submission demonstrate substantial equivalence to the predicate devices listed above. Overall, the subject device has the following similarities to the predicate devices: - have the same intended use, - use the same operating principles, - incorporate the same basic designs, - incorporate similar materials, and - have similar packaging and are sterilized using the same materials and processes. --- **Source:** [https://fda.innolitics.com/device/K242303](https://fda.innolitics.com/device/K242303) **Published by [Innolitics](https://innolitics.com)** — a medical-device software consultancy.
