Hi Ron, I have good experience with the LIPUS, described by prof. Watson. It was a 86 yo patient with nonhealing proximal humerus comminuted fracture, surgicaly reduced with ORIF. It was not healed for 6 months when we started the LIPUS therapy. After two months there were Rx signs for fracture healing. After that we continiued for 3 or 4 weeks more and than discontiniued the therapy as three indipended orthopedic doctors confirmed that the fracture has healed. The therapy was delivered by a special LIPUS machine, called Osteotron, which I believe was made in Japan. The parameters were exactly as the described by prof. Watson. Hope it helps.
