Objective: to evaluate the use of intra-articular anaesthesia combined with positive contrast arthrography (collectively called ‘anaesthetic arthrography’ [AA]) in the shoulder in order to identify and confirm the source of pain in lame dogs.

Methods: anaesthetic arthrography was performed in 30 dogs with shoulder joint lameness with a mixture of contrast medium (iohexol: 240 mg i/ml) and a local anaesthetic (mepivacaine 2%:

20 mg/ml). The effect of intra-articular anaesthesia was evaluated by an objectified visual scoring system and the arthrograms were evaluated for their diagnostic value. ...
