Hydrodilatation invented by an Australian doctor is the best procedure to have for frozen shoulder. I had this done to both of my frozen shoulders and I walked out of the outpatients that day able to get full rotation of my shoulders. It involves a needle into the shoulder cavity guided by xray and they inject about 40 to 60 ml of water and some local anesthetic into the cavity and it pops it back out of the ‘lock’ of the ‘frozen’ shoulder. I think there are now some doctors doing it in the US and UK. It works very well and the only risk from having it done is obvious things like infection etc like any procedure.
