Non-human primate cervical subtotal discectomy prosthesis (CSDP) implantation surgery. (A) After separating the skin, the platysma was cut with an electric knife. Then, the envelope fascia was sharply separated until the sternocleidomastoid muscle was seen. The sternocleidomastoid muscle was separated from the scapulohyoid muscle. Finally, the vertebral body was exposed by peeling off the longuscolli. (B) The size of the CSDP was modified based on the cervical spine anatomy of the non-human primates before implantation.
