Subacromial bursitis is an intense pain in your shoulder that gets worse when you move. Getting treatment early can help prevent long-term. El síndrome subacromial es una lesión por uso excesivo del síndrome subacromial, tendinitis del supraespinoso y bursitis del hombro. 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.

Subacromial bursitis is a condition caused by inflammation of the bursa that separates the superior surface of the supraspinatus tendon one of the four tendons of the rotator cuff from the overlying coraco-acromial ligamentacromion, sbacromial coracoid the acromial arch and from the deep surface of the deltoid muscle. Musculoskeletal complaints are one of the most common reasons for primary care office visits, and rotator cuff disorders are the most common source of shoulder pain.

Primary inflammation of the subacromial bursa is relatively rare and may arise from autoimmune inflammatory conditions such as rheumatoid arthritis ; crystal deposition disorders such as gout or pseudogout ; calcific loose bodies, and infection.

These factors are broadly classified as intrinsic intratendinous or extrinsic extratendinous. They are further divided into primary or secondary causes of impingement. Secondary causes are thought to be part of another process such as shoulder instability or nerve injury.

In Neer described three stages of impingement syndrome. The Neer classification did not distinguish between partial-thickness and full-thickness rotator cuff tears in stage III. InPark et al. For the diagnosis of impingement disease, the best combination of tests were “any degree of a positive Hawkins—Kennedy testa positive painful arc sign, and weakness in external rotation with the arm at the side”, to diagnose a full thickness rotator cuff tearthe best combination of tests, when all three are positive, were the painful arc, subbacromial drop-arm sign, and weakness in external rotation.

Subacromial bursitis often zubdeltoidea with a constellation of symptoms called impingement syndrome. Pain along the front and side of the shoulder is the most common symptom and may cause weakness and sundeltoidea. The onset of pain may be sudden or gradual and may or may not be related to trauma. Night time subacromiwl, especially sleeping on the affected shoulder, is often reported.

Localized redness or swelling are less common buursitis suggest an infected subacromial bursa.

Individuals affected by subacromial bursitis commonly present with concomitant shoulder problems such as arthritisrotator cuff tendinitisrotator cuff tearsand cervical radiculopathy pinched nerve in neck. Impingement may be brought on by sports activities, such as overhead throwing sports and swimming, or overhead work such as painting, carpentry, or plumbing.

Activities that involve subacrojial overhead activity, or directly in front, may cause shoulder pain. Direct upward pressure on the shoulder, such as leaning on an elbow, may increase pain.

The literature shbacromial the pathophysiology of bursitis describes inflammation as the primary cause of symptoms. Inflammatory bursitis is usually the result of repetitive injury to the bursa. In the subacromial bursa, this generally occurs due to microtrauma to adjacent structures, particularly the supraspinatus tendon.

The inflammatory process causes synovial cells to multiply, increasing collagen formation and fluid production within the bursa and reduction in the outside layer subdeltoifea lubrication. Less frequently observed causes of subacromial bursitis include hemorrhagic conditions, crystal deposition and infection.

Many causes have been proposed in the medical literature for subacromial impingement syndrome. The bursa facilitates the motion of the rotator cuff beneath the arch, any disturbance of the relationship of the subacromial structures can lead to impingement.


These factors can be broadly classified as intrinsic such as tendon degeneration, rotator cuff muscle weakness and overuse. Extrinsic factors include bone spurs from the acromion or AC jointshoulder instability and neurologic problems arising outside of the shoulder.

It is often difficult to distinguish between pain caused by bursitis or that caused by a rotator cuff injury as both exhibit similar pain patterns in the front or side of the shoulder. Irritation or entrapment of the lower subscapular nervewhich innervates the subscapularis and teres major muscles, will produce muscle guarding at the shoulder that will restrict motion into external rotation, abduction, or flexion. The aforementioned tests will assist in diagnosing bursitis over other conditions.

The diagnosis of impingement syndrome should be viewed with caution in people who are less than forty years old, because such individuals may have subtle glenohumeral instability. X-rays may help visualize bone spursacromial anatomy and arthritis. Further, calcification in the subacromial space and rotator cuff may be revealed. Osteoarthritis of the acromioclavicular AC joint may co-exist and is usually demonstrated on radiographs.

MRI imagining can reveal fluid accumulation in the bursa and assess adjacent structures.

In chronic cases caused subacromil impingement tendinosis and tears in the rotator cuff may be revealed. At USan abnormal bursa may show. In any case, the magnitude of pathological findings does not correlate with the magnitude of the symptoms. In patients with bursitis who have rheumatoid arthritisshort term improvements are not taken as a sign of resolution and may require long term treatment to ensure subacromixl is minimized.

Joint contracture of the shoulder has also been found to be at a higher incidence in type two diabetics, which may lead to frozen shoulder Donatelli, Many non-operative treatments have been advocated, including rest; oral administration of non-steroidal anti-inflammatory drugs ; physical therapy ; chiropractic ; and local modalities such as cryotherapyultrasoundelectromagnetic radiation, and subacromial injection of corticosteroids.

Shoulder bursitis rarely requires surgical intervention and generally responds favorably to conservative treatment. Surgery is reserved for patients who fail to respond to non-operative measures. Minimally invasive surgical procedures such as arthroscopic subxeltoidea of the bursa allows for direct inspection of the shoulder structures and provides the opportunity for removal of bone spurs and repair of any rotator cuff tears that may be found. In Morrison et al.

An attempt was made to exclude patients who were suspected bursitks having additional shoulder conditions such as, full-thickness tears of the rotator cuff, degenerative arthritis of the acromioclavicular joint, instability of the glenohumeral joint, or adhesive capsulitis.

All patients were managed with anti-inflammatory medication and a specific, supervised physical-therapy regimen. The patients were followed up from six months to over six years. Of the patients who improved, 74 had a recurrence of symptoms during the observation period and their symptoms responded to rest or after resumption of the subdeltlidea program. The Morrison study shows that the outcome of impingement symptoms varies with patient characteristics.

Younger patients 20 years or less and hursitis between 41 and 60 years of age, fared better than those who were in the 21 to 40 years age group. This may be related to the peak incidence of work, job requirements, sports and hobby related activities, that may place greater demands on the shoulder.

However, patients who were older than sixty years of age had the “poorest burstiis. It is known that budsitis rotator cuff and adjacent structures undergo degenerative changes with ageing. The authors were unable to posit an explanation for the observation of the bimodal distribution of satisfactory results with regard to age. They concluded that it was “unclear why those who were twenty-one to forty years old had less satisfactory results”.


The poorer outcome for patients over 60 years old was thought to be potentially bufsitis to “undiagnosed full-thickness tears of the rotator cuff”.

Educate the patient about their condition and advise to avoid painful activities and the importance of relative rest of the shoulder.
