activ® C is the cervical disc prosthesis for a motion preserving treatment of degenerativ cervical disc disease. It is indicated for light to moderate degeneration of cervical disc with light to moderate changes of the disc, vertebral endplates, osteophytes and/or with fresh herniated disc. The specific motion pattern, physiological center of rotation and the shape of prosthesis-plates ensure the best possible adaption to natural anatomy and biomechanics of the patient for a fast reduction/elimination of pain/neurological deficits and a longterm preservation of motion patterns and the protection of adjacent levels.
Safe anchorage and prevention of vertebral body splitting by the combination of spikes and keel and specific technique of keel preparation
Improved primary stability and fast ingrowth fo bone cells through Plasmapore® coating
Fast and safe bonding between bone and prosthesis surface
Natural motion pattern through shape and type of inlay/prosthesis, analogy between motion patterns of facet joints and prothesis
Good conformity with anatomy of vertebral body and improved primary stability by anatomical shape of prosthesis plates
Safe and easy application in cases with narrow disc space through small height of prosthesis
Felxible use in different grades of degeneration through specific designs
Low risk of complication by safe materials and simple surgical technique
Motion preserving treatment of degenerativ cervical disc disease.
Light to moderate degeneration of cervical disc with light to moderate changes of the disc, vertebral endplates, osteophytes and/or with fresh herniated disc.
Age is limited by the maturation of epiphysis in young adults and the bone and healing quality in higher age.
Primary stability by a combination of spikes and keel
Secondary and primary stability by Plasmapore® coating
Radius of inlay adapetd to mean values of normal distribution of anatomy
Anatomical shape of prosthesis plates
Smallest height with 5 mm
Different designs for indications with light to moderate degeneration
