Convulsions and Coma Associated with Iatrogenically Elevated CSF Calcium Levels Post Spinal Surgery: A Case Report.
Following elective revision of lumbar decompression and non-instrumented fusion, a 69 year old woman developed confusion, convulsions and coma associated with greatly elevated cerebrospinal fluid (CSF) calcium levels. It is presumed that the elevated calcium was secondary to the use of OsteoSet, a calcium sulfate pellet preparation used to augment autologous bone graft growth.
