Forty years ago I had a fusion which failed. I crushed L1 in a horse riding accident. Four years later I had Harrington rods put in and I was told that they must be removed within two years. No one would do this for me. Eleven years ago, I was having problems walking. After extensive testing they decided to operate and my Harrington rods were removed, but more rods were put in from T10 to L5.
