Purpose
Considering the evidence of the available literature,
the loose bodies located inside the scapulo-humeral articulation,
whether intra-articular or in the mucosal bags,
are an exceptional finding.
Even though osteocartilaginous loose bodies are most likely to be of traumatic (eg: bony-Bankart) or atraumatic (osteochondritis dissecans) origin,
in case of primary or secondary osteochondromatosis,
they can originate from synovial metaplasia.
Patients during clinical evaluation often suffer from joint pain and locking sensation.
The traditional radiological examination is useful in case of bony fragments but is intrinsically not sensitive enough for non-calcified fragments.
In those cases,
ultrasonography and,
eventually,
MRI are essential to achieve the correct diagnosis.
The earlier the diagnosis the better the results will be: early diagnosis could prevent chondral erosions or tendon injuries resulting from repeated impacts between the movable body and the joint structures.
