Perhaps you should try some spelling variations:
radiation injuries » radiation induced
luxation injuries » junction injuries, rotation injuries, amputation injuries
radiation injury » radiation induced
2f therapy » 2 therapy, 21 therapy, 20 therapy

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: %((((22((radiation injuries) OR (radiation injury))) OR (luxation injuries))) OR (((radiation injuries) OR (radiation injury)))) %((2f therapy) OR (2 therapie))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((((22((radiation injuries) OR (radiation injury))) or (luxation injuries))) or (((radiation injuries) OR (radiation injury)))) %((2f therapy) or (2 therapie))%22".
• Adding a wildcard symbol may retrieve word variants: %((((22((radiation injuries) OR (radiation injury))) or (luxation injuries))) or (((radiation injuries) OR (radiation injury)))) %((2f therapy) or (2 therapie))%22*.
