title: [Os acromiale: significance--diagnosis--pathology. Apropos of 28 cases including 2 with fracture separation].
abstract: In relation to two rare cases of fracture-separation of the os acromiale, 26 other cases of defective epiphysial fusion were studied. A review of the literature confirmed the rarity of this anomaly of the scapula which predisposes to subacromial impingement and rotator cuff rupture. The diagnosis is radiological. It requires both an antero-posterior and an axillary view which, together with a CT scan, precisely shows the os acromiale. It should be distinguished from a fracture of the acromion to avoid unnecessary immobilisation and post-traumatic effects. Degenerative changes provoke an impingement syndrome, the surgical treatment of which must include arthrodesis of this ossicle.
