Perhaps you should try some spelling variations:
22radiation injuries » radiation injury, friction injuries
radiation injuries » radiation injury, radiation induced
rotation injuries » luxation injuries, motion injuries, amputation injuries
2f therapy » rf therapy, tnf therapy, 2.2 therapy
2 therapy » 2 therapie

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: %((((22radiation injuries) OR (rotation injuries))) OR (radiation injuries)) %((2f therapy) OR (2 therapy))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((((22radiation injuries) or (rotation injuries))) or (radiation injuries)) %((2f therapy) OR (2 therapy))%22".
• Adding a wildcard symbol may retrieve word variants: %((((22radiation injuries) or (rotation injuries))) or (radiation injuries)) %((2f therapy) OR (2 therapy))%22*.
