I have a back injury. Before the operation I was 6ft 1in and after the operation I was 6ft dead on. This is despite replacing a disc with a lump of plastic.
This could be explained away by posture issues. When I was way more obese than I am now, I had posture problems. Before I got obese I averaged 6ft 4in. Once I was obese I lost 2 inches. Later I found out after seeing someone who specializes in physical therapy that I just wasn't standing as straight as I could have been and had been hunched over enough to lose the 2 inches. I lost the weight and sort of improved my posture and got the 2 inches back.
If you injured your back and it doesn't curve in the same way it used to or you've adapted your posture to the injury and post recovery, this could easily explain the loss in height.
On a side note, you do lose skeletal mass as you get into the elderly age bracket, and you will probably be shorter at that time in life then you are now.
