Abstract

Ossification of the posterior longitudinal ligament (OPLL) is a condition where abnormal bone growth occurs within the spinal ligament. While often asymptomatic, OPLL can lead to spinal cord compression, resulting in neurological symptoms. A 66-year-old Thai man with progressive upper extremity weakness was diagnosed with OPLL and underwent cervical decompression surgery. Despite the surgery, the patient developed postoperative lower extremity weakness (paraparesis). Further investigation revealed reduced blood flow during surgery, and a subsequent CT brain scan demonstrated pre-existing bilateral anterior cerebral artery infarction. This case highlights the complexity of managing OPLL and the importance of a comprehensive approach involving multiple medical specialties.
