Heterotopic ossification(HO) and progressive bone formation(PBF) are main factors affecting the motion ability of target segments after cervical artificial disc replacement(CADR).The severity of pre-operative degeneration of target segment is the most important factor in the occurrence and progression of HO and PBF. The occurrence and progression of HO and PBF can be reduced basically through the improvement of degeneration evaluation system for intervertebral disc (including height, range of motion and osteophyte formation), uncovertebral joint and facet joint and standardization of surgical indication. The application of new anatomical prosthesis and improved surgical technique are also important factors to reduce the occurrence and development of HO and PBF.
