Secure a loose vertebra by tightening a ligament?
A recent article reported that the Saudi King had surgery to secure a loose vertebra by tightening a ligament, this does not sound like any procedure I am familiar with domestically. Internet search provides nothing,
"The king, in his late 80s, underwent an operation to tighten ligaments around his third vertebra in October of last year...."
"The official said Saturday's surgery at the King Abdel Aziz medical compound in Riyadh sought to secure a loose vertebra. "
This phrasing seems awkward if they are simply describing a fusion, anybody know what type of procedure this refers too?
