Cervical Disk Arthroplasty: Surgical Technique and Technical Pearls

Cervical disk arthroplasty is indicated for the management of two-level cervical radiculopathy or myelopathy. Cervical disk arthroplasty is associated with better postoperative outcomes compared with two-level anterior cervical diskectomy and fusion (ACDF). Although the surgical approach for cervical disk arthroplasty is similar to that of ACDF, several key differences exist. First, diskectomy requires thorough foraminal decompression, with more limited uncinate resection than required for ACDF. Second, limited use of the burr or electrocautery is important to prevent heterotopic ossification. Finally, optimal implant sizing and midline placement are critical to ensure restoration of biomechanics.
