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

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