Results
Images showed a spectrum of tears involving the biceps pulley complex and were subdivided into four groups according to the Habermeyer classification: 3 patients had superior gleno-humeral ligament (SGHL) tear (Type I) (Fig.1),
5 patients had SGHL and supraspinatus tendon (SSP) tears (Type II) (Fig.
2),
7 patients SGHL and subscapularis tendon (SSC) tears (Type III) (Fig.
3) and 8 patients SGHL,
SSP and SSC tears (Type IV) (Fig.4).
Arthroscopic evaluation demonstrated that 1 patient had Type I,
5 patients Type II,
5 patients Type III and 10 patients Type IV lesions.
Arthro-MRI scans performed in extrarotation showed an inchoate anteromedial subluxation of the LHBT in patients with Type II lesion.
A LHBT significant anteromedial subluxation was always demonstrated in patients with Type III and Type IV lesions.
At the dynamic tests,
during arthroscopy,
only 13 patients had ASI features (3 with Type III and 10 with Type IV lesions).
