The Kunovus Disc Device aims to preserve the structural and biomechanical integrity of the lumbar intervertebral disc in patients undergoing a discectomy procedure
Chronic low back pain is frequently due to the defects or failures of the lumbar intervertebral disc, leading to herniation of the inner disc material. This can cause irritation and/or mechanical compression of the spinal cord or the exiting nerves, which results in pain and/or reduced mobility. The conventional surgical approach for treating lumbar disc herniation is discectomy, wherein the loose nuclear fragments in the spinal canal are removed and clearance of the nuclear cavity is performed. Although discectomy generally results in immediate pain relief, the operated disc may gradually collapse and become a source of recurrent pain. Recent data shows that one in five discs will re-herniate within the first decade of surgery, necessitating another surgical procedure. The Kunovus System and the Kunovus Disc Device have been developed to address this procedural lacuna and aims to preserve the structural and biomechanical integrity of the lumbar intervertebral disc after a discectomy procedure.
