Mom went into the operating room shortly before 1pm. They'll be fusing 3 vertebrae, and determining during surgery if a brace will be necessary. Please pray that a brace is not required. It will be a rather unpleasant 6 - 8 weeks for Mom if one is required. Given the location of the vertebrae being fused, the brace would require the inclusion of a thigh (that is, the position of at least one leg would be fixed for the 6-8 week period.
Surgery (once they get started) will take just over an hour, then at least an hour in recovery.
More post-surgery! Please pray in the meantime!
