Clinical Picture:
Usually a full range of movement.
Sometimes pain at the end of passive range.
Most typically in combination with a painful arc .
A chronic subdeltoid bursitis is not the late result of an acute subdeltoid bursitis. The inflammation is localised from the onset : only a small part of the bursal wall is affected.
The localisation may be
- under the acromial roof : acromion and coraco-acromial ligament (subacromial)
- under the deltoid muscle (superficial).
There is marked local tenderness if the lesion is at the deltoid area.
