The most important step is to accurately diagnose the condition. This is done by an accurate physical examination. On occasion, I will get an XR and MRI scan of the shoulder to exclude other conditions that can mimic a Frozen Shoulder.
The commonest way that I treat a Frozen Shoulder is by a procedure called a Hydrodilatation. This is where a Radiologist injects the shoulder joint with anaesthetic and steroid, followed by sterile saline to stretch the capsule. The procedure may cause a feeling of tightness, pressure or heaviness in the shoulder and arm. A minority of people describe the procedure as painful. The procedure should take less than 10 minutes to do. After the procedure, the shoulder may feel squelchy for a day or two. Once the anaesthetic wears off, the shoulder can be achy for a few days.
3-4 days following the procedure, your physiotherapist should re-start gentle passive stretches to help improve the range of motion. How much or how little you do, is dependent on what your shoulder feels like.
On occasion, a second hydrodilatation may be recommended, if the first does not do the trick. Thanks to the success of the majority of hydrodilatations, it is uncommon that a surgical procedure (such as a manipulation under anaesthetic or shoulder arthroscopy) is required.
Any surgical or invasive procedure carries risks. Before proceeding, you should seek a second opinion from an appropriately qualified health practitioner.
