Cervical Total Disc Replacement: Indications and Technique

Cervical Arthroplasty: A Clinical Update

“…Current indications include 1 or 2 contiguous levels of cervical pathology; herniated cervical disc without significant loss of disc height; cervical spondylosis or degenerative disc disease; and cervical radiculopathy or myelopathy. 24,25 Contraindications include more than 2 levels of adjacent cervical pathology; patients older than 65 years; significant loss of disc height or significant cervical deformity in the sagittal or coronal plane; cervical instability; prior surgery 3…”

Cervical Radiculopathy: Focus on Factors for Better Surgical Outcomes and Operative Techniques

“…3) Location of implant After applying the implant to the disc space, fluoroscopic imaging should confirm proper positioning [54,61]. The proper position of the device in the coronal plane is to check the line connecting the spinous process that is projected with the center of the stone connecting the unit on fluoroscopy.…”

“…The semi-constrained types include the ProDiscC, Prestige ST, Simplify, M6, and Secure-C, which are known to demonstrate similar results to those of the unconstrained types. Recently, a patient-specific device using 3D printing has been introduced, which may have a better effect on patient outcomes in the future [ 49 , 54 ].…”

“…There are advantages and disadvantages to preserving and removing the PLL. The hypotheses that preserving the PLL can maintain adequate cervical ROM and that removing the PLL can cause hypermobility are conflicting [ 54 ]. Voronov et al [ 63 ] have suggested that hypermobility can be solved by applying a stiffer device during device implantation.…”

“…Kim et al [ 64 ] also mentioned that PLL is already damaged in case of severe herniation of the disc material, so it is removed only in this case. Some surgeons consider PLL removal the best means to ensure sufficient decompression [ 54 ].…”
