Hi, I'm new to this site but not new to the world of neck pain. I would like to hear from anyone that has had a failed acdf surgery since I'm scheduled to have a revision on April 30th and am extremely nervous. My failure is two-fold. Apparently my cadavar graft did not heal and then in February I was involved in a rear end collision (I was the one hit). I felt fine right after the wreck but by that evening, I was feeling some pain. I scheduled an appt. to see my GP and was told that what I was feeling was muscle stiffness. This was on Friday and by Monday there was a significant increase in discomfort. I then went to see my surgeon who took an xray and reported that the hardware appeared to be fine. After a couple more weeks of worsening pain, I finally requested a CT scan which was done. At my flup appt. I found out that the graft (one level) had in fact not healed and now there is a large crack in the graft, most likely caused by the collision. The revision will be done with an autograft this time and the whole thing is making me very nervous!!! I would appreciate any replies as to pain level and more importantly, the successes!!! Thanks so much!!
