Conclusion
ASI was associated with more or less extensive tears of the biceps pulley.
Habermeyer first described the combination of these tears with arthroscopy.
According to this classification we propose an initial diagnosis with a Type I,
II,
III and IV pattern.
Arthroscopic findings matched the proposed initial diagnosis as shown in Table 1.
Arthro-MRI can provide complete depiction of the rotator cuff,
the biceps pulley and the anterior tendinous components of the rotator cuff; its limits are mainly related to the low specificity in the identification of SGHL tears.
On the other hand,
the use of dynamic acquisitions (in internal and external rotation) is useful in the detection of early LHBT instability and could suggest the presence of ASI.
However in our experience,
according to arthroscopic dynamic tests,
only complex lesions of the pulley system and of the LHBT are probably related to ASI.
