Thirty-five patients with cervical OPLL after anterior decompressin surgery were followed up, and fifteen of them showed radiologically recognized reossification of OPLL at the ossification-removed levels. They were examined by CT scanning. The CT findings of ossification were classified into four types by the manner of reossifications. The etiology of reossification is unknown.
