ACC Review: Rotator cuff disorders Part 2 – Management Issue 14 November 2004 General points Simple analgesics (e.g. paracetamol) may provide adequate pain relief. Use NSAIDs with some caution Use subacromial corticosteroid injection with caution but avoid where surgery may be considered as a future treatment option Supervised exercise may be beneficial but avoid therapeutic ultrasound If there is no improvement with non-operative management, refer to a specialist (see ACC Review Rotator Cuff Disorders Part 1 Diagnosis): within 4-6 weeks, for those with a full thickness tear at 6 months, for those with tendinosis/partial tears Refer patients with massive full thickness tears to a specialist immediately Background The recommendations for the management of rotator cuff disorders, summarised below, are based on the recent ACC guideline on the diagnosis and management of soft tissue shoulder injuries.1 Diagnosis is covered in the ACC Review - Rotator Cuff Disorders Part 1 – Diagnosis. Rotator cuff disorders include bicep tendon disorders, which should be managed like tendinosis. Non-operative Management The overall evidence to support or refute common interventions for rotator cuff disorders is unclear [1++]. The ACC guideline reviewed evidence on individual treatments where available. Tendinosis / partial tears Activity modification - People with acute pain can stay active but should avoid extremely painful movements. Activity can be increased as pain settles. Analgesia - Simple analgesics (e.g. paracetamol) may provide adequate pain relief. Non-steroidal anti-inflammatory drugs (NSAIDs) provide short-term symptomatic relief [1+] but there are possible adverse effects to consider (e.g. gastrointestinal bleeding, bronchospasm). Subacromial corticosteroid injection - This provides short-term symptomatic relief [1++], but should be used with caution as long term harm has not yet been established. Potential adverse effects include facial flushing, site infection, post-injection fl are and hyperglycaemia in patients with diabetes. A Cochrane metaanalysis3 found that the subacromial injection may be no more effective than NSAIDs. Refer to ACC Review Issue 6, December 2003. The benefits relative to physiotherapy are also unclear [1+]. It is advisable to document informed consent for this injection. Rehabilitation - There is some evidence that supervised exercise is beneficial. There is also good evidence that ultrasound is of no additional benefit and should not be used2 [1++]. Consider supervised active rehabilitation for people whose symptoms have failed to settle with activity modification and analgesics. Referral - Refer people to an orthopaedic specialist at six months if there is a poor response to treatment. Full thickness tears Non-operative management is appropriate in the acute phase of these tears. Activity modification and analgesia - The same consideration as for tendinosis and partial tears applies for these tears. Subacromial corticosteroid injection - There is insufficient evidence to determine the harm or benefit [1++]. It may be appropriate as part of longterm management where surgery is not considered as a future treatment option [4]. Note the discussion and cautions for tendinosis/partial tears. Rehabilitation – Supervised exercise may be of limited benefit when the acute symptoms have settled [4]. Referral - Active and physiologically young people who have a full thickness tear due to significant trauma should be referred to an orthopaedic specialist within 4-6 weeks if there is a poor response to non-operative management. Operative management for tears due largely to attrition (minimal trauma) may not be appropriate in older sedentary people. Massive tear Refer people with a massive tear immediately for orthopaedic evaluation. Delay compromises optimal outcomes for patients. Operative Management There is insufficient evidence regarding the benefit of surgical versus nonoperative management [1++]. However, there is consensus that early surgical management for a massive tear has the most to offer people who are physiologically young and active [4]. If in doubt, refer for specialist evaluation. Summary There is little evidence to support or refute common treatments. If pain is a problem, use simple analgesia or NSAIDs with caution. Activity modification and supervised exercise may be of benefit. Subacromial corticosteroid injections provide short-term symptomatic relief but use with caution and avoid where surgery may be undertaken. Therapeutic ultrasound is of no additional benefit and should be avoided. The timeframe to refer to a specialist depends on the tear. Refer massive tears immediately. References 1.
