(purpose)
The description of incomplete rotator cuff tears using arthrography seems to be difficult. The purpose of this study is to evaluate the diagnostic value of cine radioarthrography.
(Materials and methods)
The subjects consisted of eighty shoulders of 80 patients who had been diagnosed as incomplete rotator cuff tears clinically; consisting of 62 males and 18 females, ranging in age from 16 to 75years(average,51.7 years).
The types of tears were 70 shoulders with articular side tears,8 with intratendinous tears and 2 with bursal side tears.
The arthrographic findings were compared to the surgical findings retrospectively.
(Results)
Fifty-five shoulders,68.7% showed pooling of the contrast medium in the rotator cuff and 25 shoulders,31.2% showed leakage to the subacromial bursa. In articular side tears,50 shoulders had pooling and 20 had leakage, in intratendinous tears,5 shoulders had pooling and 3 shoulders leakage, and in the bursal side tears,2 shoulders had leakage.
(Conclusion)
1) The findings of leakage to the subacromial bursa in 25 shoulders could represent the existence of a microperforation even in an incomplete rotator cuff tear.
2) It was suggested that cine-radioarthrography could be useful and necessory for the diagnosis of an incomplete rotator cuff tear.
