The word comes from the name of the family Anatidae, and was used in Gary Larsons The Far Side. Anoraknophobia – a portmanteau of "anorak" and "arachnophobia". It was used in the Wallace and Gromit comic book Anoraknophobia. Also the title of an album by Marillion. Arachibutyrophobia – fear of peanut butter sticking to the roof of the mouth, from Latin arachis "peanut" and butyrum "butter". The word is used by Charles M. Schulz in a 1982 installment of his Peanuts comic strip, and by Peter ODonnell in his 1985 Modesty Blaise adventure novel Dead Mans Handle. Charlophobia – the fictional fear of any person named Charlotte or Charlie, mentioned in the comedic book A Duck is Watching Me: Strange and Unusual Phobias (2014), by Bernie Hobbs. The phobia was created to mock name bias, a form of discrimination studied by researchers at the University of California, Berkeley and the University of Chicago. Hippopotomonstrosesquipedaliophobia – fear of long words, from the root word sesquipedalophobia combined with monstrum and hippopotamus. This was mentioned on the first episode of Brainiac Series Five as a Tickles Teaser. Keanuphobia – fear of Keanu Reeves, portrayed in the Dean Koontz book, False Memory, where a woman has an irrational fear of Reeves and has to see her psychiatrist, Mark Ahriman, each week, unaware that she only has the fear in the first place because Ahriman implanted it via hypnotic suggestion to amuse himself. He calls her "Keanuphobe" in his head.
The role of disc replacement must come from new indications not defined in todays literature or a relaxation of current contraindications.A study by Regan     found the result of replacement was the same at L4-5 and L5-S1 with the CHARITE disc. However, the ProDisc II had more favorable results at L4-5 compared with L5-S1.A younger age was predictive of a better outcome in several studies. In others it has been found to be a negative predictor or of no predictive value. Older patients may have more complications.Prior spinal surgery has mixed effects on disc replacement. It has been reported to be negative in several studies. It has been reported to have  no effect in other studies. Many studies are simply inconclusive. Existing evidence does not allow drawing definite conclusions about the status of disc replacement at present. Electrical stimulation
Many failed back patients are significantly impaired by chronic pain in the back and legs. Many of these will be treated with some form of electrical stimulation. This can be either a transcutaneous electrical nerve stimulation device placed on the skin over the back or a nerve stimulator implanted into the back  with electrical probes which directly touch the spinal cord. Also, some chronic pain patients utilize fentanyl or narcotic patches. These patients are generally severely impaired and it is unrealistic to conclude that application of neurostimulation will reduce that impairment. For example, it is doubtful that neurostimulation will improve the patient enough to return to competitive employment. Neurostimulation is palliative.
