By way of background here is an email I sent to the orthopaedic surgeon's secretary which explains all except what had had happened at the time. Read on to discover how I found out that the hip had dislocated (2 weeks ago!) and how this might yet be sorted out.
I was seen by the radiographer inside 5 minutes and the first clue that I had as to what was going on was when, after the initial X-ray of both hips, 2 more were taken of the head of femur and acetabulum of my right hip. Conspiratorial whispers between the 2 radiographers aroused my fears that the hip joint had dislocated. When they said they were arranging for a wheel chair, to take me to see the doctor again, it was pretty clear what had happened. They could not confirm that the hip had dislocated as this was "best left to the doctor to explain".
5 minutes later I was staring at a very clear picture which showed the round head of femur isolated from and outside of the cup. It had popped out and up. To my eye it was about one and a half inches above the centre line of the socket and about an inch to the outside. (no wonder my balance was affected!)
The rheumatologist spoke to the orthopaedic surgeon from another room as her phone was not working so I had to rely on her report of the discussion. The surgeon had said I was to go to a ward at his hospital and they would "pop it back". It sounded like this would be a manipulation and not require surgery at all. The rheumatologist could not confirm this but did agree it was possible.
A taxi was booked to take me home to prepare to get into the other hospital. I had taken a bus to the rheumatology clinic but they were reluctant for me to return home by bus with a dislocated hip - not surprising I suppose. A taxi was arranged. I rang a neighbour who agreed to take me in, I gathered overnight stuff together in an bag and decided not to have any food or drink in case a general anaesthetic would be required. I then rang my wife to leave a message but as it happened she was just finishing a morning clinic and was due to do admin in the afternoon so instead she caught a bus home and I told the neighbour his help would not be required - this time.
