My Mum, also 89 with a broken hip, is in theatre as I write. The drs have warned me that it is high risk and even if she survives the op things could go downhill quickly during rehab. I'll say a little prayer for them both.I am having similar problems, my 89 yr old mum broke her hip 5 weeks ago in nursing home. In rehab after hip operation. Physio not working for her. Rapid change since Sunday. More confused than normal. On antibiotics for an infection. Now unable to eat or drink normally. On thickened liquids etc. Not sure what has happened and why so quickly.
