Perhaps you should try some spelling variations:
radiation injuries » radiation induced
luxation injuries » junction injuries, amputation injuries, friction injuries
rotation injuries » motion injuries, amputation injuries, extraction injuries
radiation injury » radiation induced
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: %((((radiation injury) OR (((luxation 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: "%((((radiation injury) or (((luxation injuries) OR (rotation injuries))))) or (radiation injuries)) %((2f therapy) or (2 therapy))%22".
• Adding a wildcard symbol may retrieve word variants: %((((radiation injury) or (((luxation injuries) OR (rotation injuries))))) or (radiation injuries)) %((2f therapy) or (2 therapy))%22*.
