Results
For this case series review,
we selected patients that presented with persistent shoulder pain,
functional impairment and/or persistent shoulder instability after shoulder surgery.
From the forty-four patients enrolled in this study,
there were twenty-eight men and sixteen women.
The pathology seen before the surgery are divided between rotator cuff tear,
Bankart lesion,
calcified tendinitis and acromion-clavicular fracture (table 1).
In some patients the rotator cuff lesions were accompanied with glenohumeral instability,
usually labrum tears.

Thirty-six patients,
that underwent surgery and had persistent symptons after surgery,
had post-surgical complications,
diagnosed on the post-surgical MRI scan (table 2).

Table 2.
Distribution of the postoperative shoulder complications.
The most common complication was tear or retear of the rotator cuff tendons (supraspinatus,
infraspinatus and subscapular),
followed by labrum lesions and superior displacement of the humeral head.
We found one humeral head fracture,
one glenohumeral arthrosis and one glenohumeral osteoarthritis (Figures 8 – 17).
