What are the different types of bursae in the shoulder?
The major bursae in the shoulder are: Subscapular Bursa or the Scapulothoracic Bursa: between the tendon of the Subscapularis muscle and the shoulder joint capsule. Subdeltoid Bursa: between the Deltoid muscle and the shoulder joint cavity. Subacromial Bursa: below the acromion process and above the greater tubercle of the humerus.
What is the function of the a bursa?
A bursa is a small sack of fluid. Its function is to help lubricate movement of the shoulder joint. The Supraspinatus muscle runs along the top of the shoulder blade (scapula) and inserts via the tendon at the top of the arm or humerus (upper arm) bone.
What is bursitis (bursae)?
All over your body there are small sacs filled with fluid called bursae (that’s plural for bursa). These are thin cushions between your bones and the moving parts of your body like muscles and tendons. If a bursa gets swollen and fills up with more fluid than it should, you have a condition called bursitis.
What is Sasd bursitis?
The subacromial-subdeltoid bursa (SASD) is a potentially pain-sensitive structure of the glenohumeral joint. Along with the rotator cuff tendons, it has been implicated as a primary pathology in painful shoulder conditions of overhead athletes (eg swimmers, weightlifters, gymnasts, tennis players etc).
What causes Sasd bursitis?
Subacromial bursitis is an inflammatory condition that is a common cause of shoulder pain. It is typically caused by repetitive overhead activities and minor trauma such as falls but the etiology can be multifactorial.

Does shoulder bursitis ever go away?
Full recovery from shoulder bursitis is very likely. Symptoms usually subside within a few weeks. Bursitis of the shoulder usually responds well to rest and anti-inflammatory medication. When there is another shoulder problem, such as bone problems or tendinitis, longer-term physical therapy may be needed.
Do you need surgery for shoulder bursitis?
Depending on the type of shoulder bursitis, treatment may include activity modification, immobilization with a splint, icing, injections, aspiration of the bursa (removing fluid with a syringe), antibiotics or anti-inflammatory pain medication. Surgery is rarely needed to treat bursitis.
What happens if you leave bursitis untreated?
Chronic pain: Untreated bursitis can lead to a permanent thickening or enlargement of the bursa, which can cause chronic inflammation and pain. Muscle atrophy: Long term reduced use of joint can lead to decreased physical activity and loss of surrounding muscle.
Do cortisone shots cure bursitis?
The most common type of bursitis is associated with trauma, and responds well to steroid (cortisone-type) injections. A successful steroid injection typically provides relief for about four to six months. After a successful injection, the bursitis may resolve completely and never recur.

laterally, the bursa lies over the superior surface of the supraspinatus and infraspinatus tendons. it sits deep to the deltoid muscle. subacromial impingement.
What is the subacromial subdeltoid bursa?
The subacromial-subdeltoid bursa (SASD), also simply known as the subacromial bursa, is a bursa within the shoulder that is simply a potential space in normal individuals.
What is the bursa of the subacromial subdeltoid?
The subacromial subdeltoid (SASD) bursa is one of the largest bursae in the body and plays an important role in patients with subacromial impingement. It is likely that much of the discomfort felt during arm abduction in patients with this clinical problem is due to inflammation within the bursa. Arm abduction, particularly between 30 and 60°, typically reproduces pain that is often felt over the lateral aspect of the deltoid rather than over the supraspinatus tendon itself. Patients find themselves unable to lie on the affected shoulder and sleep is interrupted. A variety of clinical signs assist in the diagnosis of impingement but do not clearly differentiate between bursitis and tendon tears. It can sometimes be difficult to differentiate between impingement and neural compression originating from cervical spondylosis. Pain obliterated by injection of local anaesthetic into the bursal space can be very helpful diagnostically.
Why is my bursa echogenic?
Haemorrhage within the bursa may also appear echogenic. This can be due to trauma, haemophilia or synovial angiomatous malformation. Less common causes include other synovial-based conditions, including infection, pigmented villo-nodular synovitis and synovial osteochondromatosis.
How to tell if bursal fluid is present?
It is generally no more than 1 mm in thickness but can occasionally be more. When fluid is present, there is separation of the fat layers and low-reflective fluid is detected. It is important not to press too hard with the ultrasound transducer or small quantities of fluid may be compressed out of the field of view and overlooked. If patients are examined in the seated position, it is important to look in the dependent area of the bursa to detect these small quantities of fluid. The probe should be passed around the margin of the deltoid so that the inferior part of the recess can be seen (Fig. 3.1). Another useful place to find small quantities of bursal fluid is anterior to the biceps tendon (Fig. 3.2). When fluid is detected around biceps, care needs to be taken to determine whether it lies within the biceps tendon sheath or within the SASD bursa. Fluid within the biceps tendon sheath extends more distally and surrounds the biceps tendon ( Fig. 3.3 ). Bursal fluid is limited by the lower limit of the bursal space anteriorly and cannot surround the tendon.
Can a bursal injection cause a full thickness tear?
Similarly, following a large volume bursal injection, if there is no increase in fluid in the glenohumeral joint or its extension into the biceps tendon sheath, communication between the bursa and glenohumeral joint indicating a full-thickness tear can also be considered unlikely.
Is bursal fluid proximal or distal?
The bursal fluid is more proximal, superficial and deep to the deltoid. The biceps sheath fluid is distal and surrounds the tendon. The presence of bursal fluid usually implies that bursitis is present, although a very tiny quantity could be considered normal.
Can a bursal ultrasound show peribursal fat?
In such cases, arthroscopy demonstrates a heavily injected but thin bursal lining. In most individuals, the normal bursa is represented by a thin, echo-poor line beneath brighter lines representing peribursal fat. Bursal thickening can be seen anywhere within the bursa, but the common locations to detect it are over the biceps tendon in long axis, around the anterior interval (Fig. 3.5) and, most commonly, over the supraspinatus tendon in the coronal plane ( Fig. 3.6 ), where the bursa abuts the coracoacromial ligament.
What is SASD bursitis?

What is the role of the bursa in shoulder pain?
This network may also provide valuable information for the proper control of the shoulder – namely to limit dangerous compressive and shear forces that may impinge the subacromial structures⁸.
What is the bursa on ultrasound?
Ultrasound. On ultrasound, the bursa is seen as an anechoic fluid-filled distended structure, with a hyperechoic wall and sometimes synovial hypertrophy. In the case of hemorrhage, there might be hyperechoic blood 2-4.
What is the pathological correlate of subacromial subdeltoid bursitis?
The pathological correlate of subacromial-subdeltoid bursitis is an inflammatory change of the bursa consistent with an increased amount of fluid and collagen formation e.g. as a result of excessive friction. Like other sorts of inflammatory conditions, subacromial-subdeltoid bursitis can be subdivided into "acute", "chronic" and "recurrent". The fluid can become hemorrhagic. In chronic bursitis, the wall becomes thicker due to the formation of collagen and might even calcify 2 and in a rare case scenario, rice bodies might be found 5. In case of an associated full-thickness rotator cuff tear, there will be a communication to the glenohumeral joint.

While MRI scanning can be used to identify bursitis, but it is uncommonly used for the diagnosis
How to heal a bursa?
What can the athlete do? 1 Rest – until there is no pain. Rest is important as every time movement causes pain in the shoulder the time taken to recover will be longer as the bursa becomes inflamed and swollen. 2 Mobility – if possible however continue pain-free mobility exercises to keep the full range of movement in the shoulder. This is important to prevent loss of movement in the shoulder and eventually muscle weakness. 3 Ice – apply cold therapy to reduce pain and inflammation. A cold pack or wrap can be applied every hour for 10 minutes reducing to 4 times a day as required. 4 Advice – see a sports injury specialist or doctor who can advise on subacromial bursitis treatment and rehabilitation.
What is the function of the subacromial bursa?
A bursa is a small sack of fluid. Its function is to help lubricate movement of the shoulder joint.
What causes subacromial bursitis?
Injury to the supraspinatus tendon may result in inflammation. As a result, the space in the joint is reduced, therefore increasing the likelihood the subacromial bursa will become impinged.
What to do if subacromial bursitis does not respond to rest and cold therapy?
Aspirate – if Subacromial bursitis does not respond to normal conservative treatment of rest and cold therapy then a doctor may aspirate the bursa which involves extracting the extra fluid through a needle injected into the bursa. Surgery – a surgeon may operate on persistent subacromial bursitis injuries.
Can a heavy fall on the shoulder cause bursitis?
Few athletes people bother to train the rotator cuff muscles, preferring to concentrate more on the muscles which accelerate the arm rather than decelerate it. A heavy fall onto the shoulder can also result in injuring the supraspinatus muscle, which may also lead to bursitis.
What is the bursa in the shoulder?
Your shoulder is another common place for bursitis. The subacromial bursa in each shoulder helps a group of muscles and tendons known as the rotator cuff to function. If it gets swollen, you have subacromial bursitis.
