The subcoracoid bursa or subcoracoid bursa of Collas is a synovial bursa located in the shoulder. It is located anterior to the subscapularis muscle and inferior to the coracoid process . Its function is to reduce friction between the coracobrachialis , subscapularis and short head of the biceps tendons , thus facilitating internal and external ...
A bursa (which communicates with the cavity of the shoulder joint [1] [2] via an aperture in the joint capsule [2]) intervenes between the tendon and a bare area at the lateral angle of the scapula [1] /the neck of the scapula. [2] The subscapularis (supraserratus) bursa separates the subscapularis is from the serratus anterior. [2]
The coracobrachial bursa is between the subscapularis muscle and the tendon of the coracobrachialis muscle. Between the capsule and the tendon of the subscapularis muscle is the subscapular bursa, this is also known as the subtendinous bursa of the scapularis. The supra-acromial bursa does not normally communicate with the shoulder joint.
A radiograph of a left hip joint, which reveals a thin, curvilinear lucent line parallel to the cortical margin of the femoral head, in a patient with avascular necrosis. In radiology , the crescent sign is a finding on conventional radiographs that is associated with avascular necrosis .
The supra-acromial bursa is located on the superior aspect of the acromion and normally does not communicate with the glenohumeral joint. [1] Supra-acromial bursitis has not been receiving much attention from literature and remains described mainly as case reports of presumptive diagnosis with no histopathological correlation. [ 2 ]
Ultrasound and MRI can help in diagnosis by assessing the coracohumeral ligament, with a width of greater than 3 mm being 60% sensitive and 95% specific for the diagnosis. Shoulders with adhesive capsulitis also characteristically fibrose and thicken at the axillary pouch and "rotator interval", best seen as a dark signal on T1 sequences with ...
The SSB bursa is located deep to the deltoid muscle and the coracoacromial arch and extends laterally beyond the humeral attachment of the rotator cuff, anteriorly to overlie the intertubercular groove, medially to the acromioclavicular joint, and posteriorly over the rotator cuff.
MRI has been shown to have 100% sensitivity and specificity in prospective studies of occult hip fractures. These fractures were diagnosed by bone marrow edema and a low signal fracture line, mainly on T1 or T2 weighted images (Figure 10). [1] Figure 10:
