or disc (dĭsk)1. Computer Science A magnetic disk, such as a hard disk, or an optical disk, such as a compact disk.2. Anatomy See intervertebral disk.Usage Have you ever noticed that when you buy a music CD, it is a compact disc, but when you buy a CD in a computer store it is usually a compact disk? Sometimes spelling varies according to how a word is used. Back in the late 19th century, when people were developing the technology for recording sound on a flat plate (what later became the vinyl phonograph record), the inventors referred to the plates as discs, using an alternate spelling of disk. The c spelling eventually became prevalent in the music industry, known for its disc jockeys. When American computer scientists developed flat storage devices back in the 1940s, they chose the common American spelling disk, and this is why we have hard disks installed on our computers. When the storage device known as the compact disk was invented, people in the music industry saw them as shiny substitutes for phonograph records, and they referred to them as compact discs, despite the fact that these same discs were compact disks when they stored nonmusical data. One of the advantages of abbreviations like CD is that they make spelling much simpler!

Patient discussion about disk

Q. Is degenerative disc disease and arthritis the same thing? My husband was recently in a auto accident at work. They did a CT Scan of his head and neck. The doctor said that the CT Scan found that he has arthritis in his neck. After receiving the report ourselves to take to another doctor it reads: "There is minimal early degenerative disc disease with osteophyte formation predominately at C5-6. " My husband never had a problem with his neck before the accident A. I was suffering from pain for 2 years and undergoing numerous test for causes when a trip to a neurologist for migraines gave me an answer. FINALLY! This was in July of this year so I am still learning and finding out about fibromyalgia but I do know in the last couple of years there has been a greater acceptance BUT there are still a lot of doctors not being supportive (from experience and talking with others) and the public in general can be unaccepting b/c you look healthy, seem to be healthy and they can not understand why you are in pain that "can't be explained!" I encourage suffers of fibro to find support within their peers! it really helps to talk to people that understand! That's what brought me to this site to start with and I am so glad I found it!

Q. What alternatives are there for DDD.De generative Disc Disease? I can't sit upright for long periods of time, at times the symptoms are worse and then days and weeks where I feel fine. When I lean into my right legit alleviates it a little but it is excruciating when I shift weight. I also have to sleep with a pillow between my legs and have to shift frequently.I have a lot of strength in my legs and back. But if I stuck in my stomach more and curve my like doing a crunch. the pain is fine.A. Degenerative disc disease can often be successfully treated without surgery. One or a combination of treatments such as Physical therapy, chiropractic manipulative therapy (CMT), osteopathic manipulation, anti-inflammatory medications such as nonsteroidal anti-inflammatory drugs, chiropractic treatments, Traction (orthopedics), or spinal injections often provide adequate relief of these troubling symptoms.
The option of surgery may be recommended if the conservative treatment options do not provide relief within 2 to 3 months. If leg or back pain limits normal activity, if there is weakness or numbness in the legs, if it is difficult to walk or stand, or if medication or physical therapy are ineffective, surgery may be necessary. You should dicucss this with an orthopedic surgeon.

Q. what does c4-5 mild central disk bulging impinging upon cervical cord without spinal stenosis or distortion of the cord . mild righ neural foraminal narrowing from uncovertebral joint hypertropy meanA. Well this basically means there is a very small narrowing of the cervical (your neck area) spinal canal (where the spinal cord is), however the narrowing does not cause any damage to the spinal cord, therefore probably does not cause any major symptoms involving the nerves. The c4-5 bulging part refers to the part in between the two cervical vertebras c4 and c5, in which the disc (a part in the spinal cord) is sliding a bit side-ways, but again, it does not seem to be causing any trouble.
