Core Tip

Core tip: Severe traction spur type heterotopic ossification (HO) occurred after cervical disc arthroplasty (CDA) with Bryan discs and matured in the second year after operation. A second CDA for the adjacent segment disease herniation of the intervertebral disc with Baguera C disc over the C3-C4 level achieved excellent outcome. Based on the second operation experience, the avoidance of unnecessary soft tissue traction and trauma such as burring, milling, or keeling during the operation and the prophylactic use of non-steroidal anti-inflammatory drugs are mandatory to prevent HO formation.
