To look at it another way, what instructions has she been given about how much weight she allowed to put through her hip? If the surgeon has said she is to be non-weight bearing or partial weight bearing, you are generally dependent on having 2 hands on a frame, and I can see why the physio isn't too involved at this stage . Now that she is a week post surgery, it is worth asking if she is allowed to use a gutter frame (takes weight through the forearms) to try mobilising, but this is again very dependent upon the wishes of the consultant, and how protective he/she is the relocation of the shoulder joint. I'm hoping she has been taught bed exercises to strengthen the muscles around the hip, and I'm surprised that no-one has been around to see how she's getting on with them.
