M6®-C Artificial Cervical Disc Two-Level IDE Pivotal Study
March 22, 2024 updated by: Spinal Kinetics
Prospective, concurrently controlled, multi-center study to evaluate the safety and effectiveness of the Spinal Kinetics M6-C™ artificial cervical disc compared to anterior cervical discectomy and fusion (ACDF) for the treatment of contiguous two-level symptomatic cervical radiculopathy at vertebral levels from C3 to C7 with or without spinal cord compression.

Detailed Description
Patients will be concurrently enrolled in the M6-C treatment group and the ACDF control group.
Patients should have failed at least six weeks of conservative treatment or demonstrate progressive symptoms despite continued non-operative treatment.
For the study, 263 patients will undergo either a two-level cervical artificial disc procedure, or an instrumented (ACDF) procedure as per site group assignment.
Patients will be evaluated clinically, radiographically, and via the collection of patient-reported outcomes at 6 Weeks, 3 Months, 6 Months, 12 Months and 24 Months.
The primary endpoint is Overall Success at 24 Months.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: M6-C Artificial Cervical Disc
The M6-C is an investigational device composed of two outer and inner endplates made of titanium with a polycarbonate urethane nucleus (plastic center) and a polyethylene fiber annulus (strong thread-like binding).
Around the polyethylene annulus is a polyurethane sheath (plastic cover).
The outer endplates have keels to anchor the disc to bone.
The outer endplates and keels are both coated with a titanium plasma spray.
The M6-C is provided in two heights (6mm and 7mm) and four footprints (Medium, Medium Long, Large, Large Long).
|
An incision will be made in the front of the neck and the damaged disc located between cervical vertebrae (neck bones) will be removed so that the M6-C artificial cervical disc can be placed into the space where the damaged disc was removed.
This procedure will be performed using x-ray technology (fluoroscopy) guide the surgeon in placement of the M6-C in between the cervical vertebrae.
This process will be repeated to replace the second damaged disc.
|
Active Comparator: Anterior Cervical Discectomy & Fusion (ACDF)
ACDF will be performed using one of four FDA-approved anterior cervical plate systems and corticocancellous allograft bone. The four plating systems used in this study are:
|
One of four FDA-approved cervical plate systems will be used for the ACDF.
An incision will be made in the front of the neck and the damaged disc located between cervical vertebrae (neck bones) will be removed.
Then, a piece of donor bone will be placed in the space where the damaged disc was removed and a metal plate will be screwed into the bones above and below the disc.
This procedure will be performed using x-ray technology (fluoroscopy) to guide the surgeon in the placement of the cervical plate system.
This process will be repeated to treat the other damaged disc.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Functional Impairment - Neck Disability Index Score (NDI)
Time Frame: 24 Month
|
Change in condition-specific functional impairment will be evaluated using a 10 item NDI outcomes questionnaire to assess change in the functional impairment score.
NDI scores range from 0-50 (0%-100%) with higher scores demonstrating greater disability.
|
24 Month

Time Frame: 24 Month
|
Quantitative and qualitative assessments compared to baseline evaluating surgical success outcomes for both cohorts.
|
24 Month
|
FOSS Dysphagia Scale
