As you say the "hot spots" may indicate healed fractures and those kind of fractures can be cause by strangulation.
And 'strangulation' always involves the neck. The supposedly-Schiavo bone scan report did not note any abnormal findings anywhere near her neck. It mentioned the thoracic & lumbar areas, ribs, sacroiliac joints, femur, knees & ankles. The Strangulation Theory is Pure BS.
You are right, I am wrong in that regard. Sorry.
Where you are wrong is that the strangulation theory is BS. Strangulation is achieved by compressing soft tissue and doesn't have to leave any bone indications. The fall once unconscious would leave some other non-neck injury that could show on a bone scan.
In any case -- she could have been strnagled. Just how many miles where on the odometer when loving Mike looked at it that night?
