Although there is still some concern that the preservation of motion may retain some micro trauma to the spinal cord, cervical disc arthroplasty is gaining acceptance as a treatment of localized cord compression due to soft disc or osteophytic hernia. We treated chronic cord compressions with a novel cervical implant (Spineart, NY) in 12 patients with a twelve-months minimal follow up. We used a limited left anterior cervical approach giving exposure to the sole affected disc in all cases.Eight patients were male and 4 female. The mean age was 46 years (18 to 92), The mean operating time was 70 minutes (50 to 90 minutes). Functional outcome was assessed using the modified Japanese Orthopedic Association scale. The technique included la left lateral prevertebral approach and exposure of the affected disc only through a 4-centimeter incision. After 12 months of follow up, all but one patients experienced improvement and had scores indistinguishable of normal. One patient had no improvement but stabilization of the functional impairment after twelve months. Skin icisions were invisible after twelve months.Cervical discectomy using a minimal skin incision and replacement with the new device appears as a safe and efficient procedure and is now our standard indication in cervical myelopathy due to localized anterior hard and soft disc hernia
