1 Impingement syndrome Impingement syndrome: resulting from compression upon shoulder flexion and internal rotation of the rotator cuff (typically the supraspinatus tendon) or swollen subacromial bursa, between the lateral portion of acromion and the head of the humerus tendons become trapped leading to compression, inflammation and damage can lead to rotator cuff tendonitis is caused by: injury general wear and tear an occupational or sporting activity requiring repetitive use of the shoulder, eg tennis or cricket 2 Clinical features The symptoms and signs of impingement syndrome, rotator cuff tendonitis and subacromial bursitis are similar and there may be some overlap between the conditions they include: pain and tenderness to upper arm, subacromial space and lateral deltoid night pain pain with upward reaching movements reduced shoulder strength, especially abduction and external rotation in the presence of a tear possible muscular atrophy usually a full range of passive movement but limited active movement due to pain and rotator cuff weakness may be reduced range of movement in the presence of a rotator cuff tear or adhesive capsulitis low painful arc of motion, with maximum pain at 60-120, is typical for impingement inability to maintain painful arm at 90 angle when arm is passively abducted and then released indicates possible tendon rupture 3 Management Consider the following: patient education advise to avoid activities that aggravate symptoms simple analgesia or non-steroidal anti-inflammatory drugs (NSAIDs) to minimise inflammation, unless contra-indicated NSAIDS: provide short-term symptomatic relief, but are associated with adverse effects contra-indications include: patients with severe renal disease Page 2 of 7
pregnancy patients with aspirin allergy prescribe with caution in patients with: hypertension gastrointestinal complaints mild liver or kidney disease use lowest effective dose and monitor renal function asthma monitor adverse effects gentle exercises to restore range of motion: stretching exercises to maintain shoulder elevation and internal and external rotation shoulder strengthening exercises once range of motion is restored advise to apply ice packs intermittently to the painful and inflamed area discourage use of arm slings if no response, consider corticosteroid and local anaesthetic injection into subacromial space: may provide symptomatic relief in the short-term for those with tendonitis or partial tears three injections in total, separated by 6 weeks in patients with diabetes, monitor blood sugar levels following intra-articular injection NB: Consider immediate referral to an orthopaedic specialist for early surgical assessment if there is any suspicion of a severe rotator cuff tear.

Clin Evid 2008; 1: 1107-31. 4 Poor response Poor response: some or all of the patient's symptoms, including pain, persist treatment does not fully restore the patient's ability to perform normal daily activities, including work, sleep, recreational and other activities 5 Good response Good response: symptoms, including pain, improve treatment restores the patient's ability to perform normal daily activities, including work, sleep, recreational and other activities 8 Investigations imaging may involve ultrasound scan, X-ray, or magnetic resonance image (MRI) as judged clinically appropriate, to: confirm or exclude diagnosis evaluate for any underlying pathology check the integrity of rotator cuff tendons Page 3 of 7

Health Technol Assess 2003; 7: 1-185. 9 Rotator cuff tear diagnosed Rotator cuff tears: can be painless or painful most patients have a longstanding history of painful shoulder condition, such as impingement syndrome or subacromial bursitis are related to repetitive use of the rotator cuff and therefore incidence increases with age; they are relatively rare before age 35 years occasionally tendon tear can be caused by acute trauma, sprain or sudden jerking injury to the shoulder may be partial or full thickness Risk factors include: subacromial spurs or impingement syndrome osteoarthritic thickening of the acromioclavicular (AC) joint systemic inflammatory conditions of the shoulders, such as rheumatoid arthritis or gout prolonged, excessive or unaccustomed use of the shoulder in the impingement position American Academy of Orthopaedic Surgeons (AAOS).

Clin Evid 2005; 1543-60. 11 Follow-up Follow-up: will depend upon the therapeutic procedure performed if rotator cuff is torn and a surgical repair has been performed: encourage patient to take passive exercise for 6-8 weeks discourage patient from making active movements for 6-8 weeks protect arm in a sling for up to 3 months if rotator cuff does not require repair: advise patient to begin active and passive movement exercises after surgery, as soon as pain is under control full recovery after procedure may take up to 9 months Page 5 of 7
