While cervical disc pathology can unquestionably produce radiculopathy, many patients presenting with arm pain, paresthesia or perceived weakness do not exhibit the clinical behavior of true nerve-root compromise. In these cases, failure to differentiate the primary pain generator may lead to unnecessary spinal injections, nerve ablation procedures or surgical consultation despite limited likelihood of benefit.
Not All Search Engines Are Created Equal
With approximately 30 million web site pages on the Internet, the volume of material accessible on any given subject is dramatically dependant on one's choice of a "search engine."
To illustrate this point, we did an Internet search for "chiropractic" using a number of the more popular search engines:
| Alta Vista | 44,800 |
| Excite | 15,864 |
| Galaxy | 93 |
| HotBot | 22,638 |
| Infoseek | 11,097 |
| Lycos | 4,481 |
| Magellan | 1,226 |
| MetaCrawler | 49 |
| WebCrawler | 1,366 |
| Yahoo | 178 |
Note: WebCrawler is the standard search engine for America Online. All of the other search engines are pre-installed with Netscape Navigator.
