Question

Quizplus · Accepted Answer

Bone spurring in the acromiohumeral space is a radiographic sign for impingement syndrome of the shoulder. It indicates the narrowing of the subacromial space, which can lead to compression of the rotator cuff tendons and bursa. Choice A, calcified tendons, can be seen in conditions such as calcific tendonitis, but is not specific to impingement syndrome. Choice B, fluid-filled joint space, can be seen in various shoulder pathologies such as bursitis and arthritis, but is also not specific to impingement syndrome. Choice C, fracture of the glenoid rim, is a completely different pathology unrelated to impingement syndrome.
