[Sub-acromio-deltoid bursography]

Subacromio-deltoid bursography may be diagnostic and/or therapeutic. As a diagnostic procedure, it opacifies the bursa, which may be more or less fused. It visualises the superior surface of the cuff, which may be fissured and it demonstrates exaggerated impression of the acromio-coracoid ligament. It is only indicated when arthrography of the shoulder is normal. As a therapeutic procedure, it constitutes a more sensitive test than Neer's test. When it is negative, the diagnosis of anterior conflict is doubtful. The addition of a corticosteroid prolongs the therapeutic effect and facilitates rehabilitation.
