Finding Orthopaedic Knowledge Online more of what you want, less of what you don’t Christian Veillette M.D., M.Sc., FRCSC Assistant Professor, University of Toronto Shoulder & Elbow Reconstructive Surgery University Health Network Deputy Editor, Information and Communication Technology Clinical Orthopaedics and Related Research Email: orthonet@gmail.com
Objectives
Develop a strategy for searching the Internet for high quality resources to use when learning on the fly
Compare different Internet search tools and determine which tool is better for a certain search
Understand common search syntax
Use the advanced search functionality of the major search engines
Where you need the information
Next Best
Is the Internet an appropriate place to look for high quality orthopaedic information?
Information overload
Commercial bias
No quality assurance
All common and legitimate comments - Biermann et al. JBJS (Am) 2006; 88:1134-1140
Yes
Lack of a strategy for searching the Internet limits success
EBM = PICO
Search = FRIAR
Effective search engine use requires learning and practice
Different types of information, different search engines
Different coverage, different search features, different algorithms for sorting results
Must KNOW your Internet resources

Power Searching on the Web
Jargon terms = Technical terms
Multiple keywords = Avoid simple search
Quotation marks = Exact phrase searching
OR = Concept groupings
Parentheses = Multiple concept groups
Limit by site/title
Limit by filetype
+ (plus sign) = Stopword searching
- (minus sign) = Exclude
~ (tilde sign) = Thesaurus or synonym searching
Tip 1: Use Jargon Terms
Specialized or technical terminology
If the sites we wish to avoid are patient oriented
the words have different meanings in various subject areas
having the words adjacent to each other changes the meaning
it is important that the same word is repeated
Tip 3: Phrase Searching
Results have fewer false positives.
Tip 4: Boolean OR
Use this when you want ANY of the terms, not ALL of the terms
with at least one of the words
Be sure to capitalize the word “OR” so Google does not ignore it
Concept grouping
“ hip osteonecrosis” OR “hip avascular necrosis” OR “hip AVN” OR “osteonecrosis femoral head”
Tip 4: Boolean OR Results have fewer false negatives.
Tip 5: Concept Group Searching with Parentheses
Group terms that should be processed together, at the same time and in the same way in the search
Want to combine with another concept or term
Question: Do steroid injections improve shoulder pain?
Concept 1 = “steroid injections”
Concept 2 = “shoulder pain”
Concept 3 = “improve”
Tip 5: Concept Group Searching with Parentheses
(“steroid injection" OR cortisone OR depomedrol OR triamcinolone) (improve OR help OR placebo) (“shoulder pain” OR “subacromial impingement” OR “rotator cuff tear”)
Tip 6: Limit by site
When you want to control the quality of the search results
Want government reports on total hip replacement?
“ total hip replacement" site:fda.gov
When you know a site that is likely to have what you need
Want CME on topic from the AAOS, but without using their site search engine?
CME ("shoulder replacement" OR “shoulder arthroplasty"”) site:aaos.org
When you want to locate a known document
Remember a patient guide but not what organization released it?
(acute back pain OR “acute back pain”) site:.org
Tip 6: Limit by site
(“total hip replacement" OR "total hip arthroplasty") site:clinicaltrials.gov
Tip 7: Limit by filetype
When you have reason to suspect that the answer you need will be in a certain format
white papers, presentations, reprint
Find a presentation
((osteonecrosis OR AVN) (hip OR femur OR “femoral head”)) filetype:ppt
Find a reprint
((osteonecrosis OR AVN) (hip OR femur OR “femoral head”)) filetype:pdf
Tip 7: Limit by filetype
((osteonecrosis OR AVN) (hip OR femur OR “femoral head”)) filetype:ppt
Tip 8: + (plus sign)
Google ignores common words and characters such as where, the, how , and other digits and letters
If a common word is essential to getting the results you want, include it by putting a "+" sign in front of it
Be sure to include a space before the "+" sign
ACJ separation type +III
Tip 8: + (plus sign)
ACJ separation type +III
Tip 9: - (minus sign)
Use the minus sign to exclude terms from results when there is a clustering of irrelevant results
Help refine a search
bone-grafting in the treatment of ununited femoral shaft fractures
nonunion femoral (shaft OR diaphysis) "bone-grafting“ -supracondylar –hip -neck
Tip 9: - (minus sign)
nonunion femoral (shaft OR diaphysis) "bone-grafting“ -supracondylar –hip -neck
Tip 10: Use Advanced Search nonunion femoral shaft OR diaphysis "bone grafting" -supracondylar -neck -hip If creating this search string comes naturally, you don’t need Advanced Search
