39 Florrimell responded to the submissions of the TAC by arguing that there was adequate evidence that the accident made a 'material contribution' to the injury.[20] He submitted that his Honour was correct to rely principally on the evidence of Dr Stobart, which I have set out above, to the effect that a new condition was discovered after the accident, namely, a bursitis or inflammatory condition in the right shoulder. As mentioned above, Dr Stobart saw Florrimell before and after the accident and had treated him for the pain in the AC joint of his right shoulder. He knew of his pre-existing condition and was in a position to identify additional pathology. This understanding was supported by Mr Dooley and the MRI image showing subacromial bursitis in the right shoulder joint. The difference in the ultrasound images taken before and after the accident also demonstrated, it was submitted, that bursitis was not present in the right shoulder before the accident and that as such, Dr Stobart's opinion was justified and his Honour was similarly justified in relying upon it. Thus, while the report of the pre-accident ultrasound of 24 November 2003 stated that there ' is no rotator cuff or tendinopathy change. Sub-deltoid bursa is not distended', the post-accident ultrasound of 27 October 2004 stated that there was a 'moderate quantity of hypoechoic fluid ... within the subdeltoid - subacromial bursa, consistent with bursitis'.
