I can't answer that as it may relate to a football player. Many don't make it back to find out. What I can tell you is that half will have some element of degeneration of disc space above and/or below the repaired level. Worsening of these areas can be expected in well over half due to the stresses now being transfered to the "good" levels. Furthermore, it is not uncommon for new areas to degenerated within a few years. Reoperation for cervical discectomy/fusion at one point in time for one reason or another is around 10%, and operation for new level degeneration 10-15." Most of the athlete recommendations to return to sports activities relate to sports such as tennis, weight lifting, golf, maybe basketball. Violent contact sports such as football and rugby don't present much data since, evidently, there are not enough numbers that return.............not only due to fear of reinjury, but also due to continued pain and/or numbness, or failure of return of strength to original level of competition (not unusual).
