Sentinel Spine

Centinel Spine is a privately held medical device company focused on anterior column reconstruction for cervical and lumbar spinal disease. The company commercializes motion-preserving total disc replacement systems under the prodisc brand and has historically also marketed integrated interbody fusion products under the STALIF brand. In 2023, Centinel divested its global fusion business to Silony Spine and sharpened its focus on motion-preservation technologies. Its current business centers on commercially available cervical and lumbar total disc replacement implants, including products in the prodisc C and prodisc L portfolios, for surgeons treating degenerative disc disease.
