FDA has approved a ZimVie PMA supplement for a smaller height of its Mobi-C Cervical Disc in seven sizes to address the anatomical needs of diverse patients. “The 4.5mm height implants are an important addition to the Mobi-C lineup,” a company release says. “Surgeons will be able to use the prostheses in more significantly collapsed discs and avoid over-distraction of the facet joints. This will expand the indications for cervical disc arthroplasty and therefore more patients can benefit from the clinically compelling Mobi-C Cervical disc.”  
  
The company says Mobi-C is the first cervical disc prosthesis approved by FDA for reconstruction of a cervical disc at both one and two levels (C3-C7). The device is a cobalt chromium alloy and polyethylene mobile-bearing prosthesis that is inserted in a single step, without requiring bone chiseling or other vertebral anchorage such as screws or keels, it says. It is indicated in skeletally mature patients for “reconstruction of the disc from C3-C7 following discectomy at one level or two contiguous levels for intractable radiculopathy (arm pain and/or neurological deficit) with or without neck pain or myelopathy due to abnormality localized to the level of the disc space and at least one of the following conditions confirmed by radiographic imaging (CT, MRI or X-rays): herniated nucleus pulposus, spondylosis (defined by the presence of osteophytes) and/or visible loss of disc height compared to adjacent levels,” according to the company.
