Intra-articular distension and steroids in the management of capsulitis of the shoulder

Dysphonia Associated with Shoulder Steroid Injection

Glucocorticosteroid injections into the shoulder are commonly used in the treatment of rotator cuff tendinitis. These injections rarely result in any serious complications and are generally considered a safe therapeutic intervention. Despite the extensive application of this treatment, there have been no reports of dysphonia occurring after corticosteroid injection into the subacromial space. We report the case of a 66-yr-old man with dysphonia after undergoing subacromial glucocorticosteroid injection for treatment of rotator cuff tendinitis.

Effects of Repeated Distension Arthrographies Combined with a Home Exercise Program Among Adults with Idiopathic Adhesive Capsulitis of the Shoulder

OBJECTIVE

The purpose of this study was to measure the effect of repeated distension arthrographies combined with a home exercise program on impairments and disability of the upper limb in subjects with adhesive capsulitis of the shoulder.

DESIGN

A total of 15 subjects with idiopathic adhesive capsulitis participated in the study. Intervention consisted of three distension arthrographies with steroid, done at 3-wk intervals, and a home exercise program. The repeated-measures design included five clinical evaluations with disability, pain, range of motion, and pain-free static strength outcomes. Two evaluations done before the first arthrography verified the stability of the condition.

RESULTS

There was a significant improvement of all outcomes at the end of intervention. The greatest effects occurred after the first distension arthrography. After the second, less marked, albeit significant, changes were observed in three motions of the shoulder and in the pain level. After the third distension arthrography, very small changes were noted. A comparison between sides revealed incomplete recovery of the range of motion on the affected side.

CONCLUSIONS

These findings showed that two distension arthrographies with steroid combined with a home exercise program reduce shoulder disability and impairments. Adding a third distension arthrography does not seem to provide any further benefit.

Shoulder injections for osteoarthritis and other disorders

Shoulder injection procedures are powerful diagnostic and therapeutic tools for the care of patients with osteoarthritis and other pathologic conditions of the shoulder-girdle region. Although questions regarding many of the details of the specific procedures still need to be answered, a modest body of literature is available. The musculoskeletal physiatrist is in a good position to contribute to this knowledge base through further clinical research.

Arthrographic joint distension with saline and steroid improves function and reduces pain in patients with painful stiff shoulder: results of a randomised, double blind, placebo controlled trial

OBJECTIVE

To determine whether arthrographic distension with a mixture of saline and steroid, in patients with painful stiff shoulder for at least 3 months, is better than placebo in improving function, pain, and range of motion at 3, 6, and 12 weeks.

METHODS

A randomised, placebo controlled trial with participant and outcome assessor blinding in which shoulder joint distension with normal saline and corticosteroid was compared with placebo (arthrogram). Outcome measures, assessed at 3, 6, and 12 weeks, included a shoulder-specific disability measure (SPADI), a patient preference measure (Problem Elicitation Technique (PET)), pain, and range of active motion.

RESULTS

From 96 potential participants, 48 were recruited. Four withdrew from the placebo group after the 3 week assessment and three subsequently received arthrographic distension with saline and steroid. At 3 weeks, significantly greater improvement in SPADI (p = 0.005), PET, overall pain, active total shoulder abduction, and hand behind back was found in participants in the joint distension and steroid group than in the placebo group. At 6 weeks the results of the intention to treat analysis favoured joint distension, although the between-group differences were only significant for improvement in PET (difference in mean change in PET between groups = 45.9 (95% CI 3.2 to 88.7). Excluding the four withdrawals, the between-group differences for the disability and pain measures significantly favoured distension over placebo. At 12 weeks, both the intention to treat analysis and an analysis excluding the four withdrawals demonstrated a significantly greater improvement in PET score for the distension group.

CONCLUSIONS

Short term efficacy of arthrographic distension with normal saline and corticosteroid over placebo was demonstrated in patients with painful stiff shoulder.

Hydrodilatation in the management of shoulder capsulitis

The aim of this study was to research the benefit of hydraulic arthrographic capsular distension (hydrodilatation) in the management of adhesive capsulitis of the shoulder. One hundred and nine shoulders with primary adhesive capsulitis were treated with hydrodilatation. Prior to the procedure, 93 shoulders were painful. Two months following the procedure, 31 continued to have some pain. In the 109 shoulders, the measured range of passive glenohumeral movement improved by approximately 30 degrees in all directions. The procedure was of similar benefit if carried out early or late in the disease process. The absolute improvement in movement range was similar in severe and mild cases. The severe cases in the long term, although improved, still had more restriction in movement and tended to have more pain than the other cases. There was considerable improvement in all the non-diabetic patients. The patients with diabetes responded less well in the long term to hydrodilatation and had an increased requirement for arthroscopic surgery. Effective treatment of adhesive capsulitis can be achieved in the majority of cases with an immediate hydrodilatation of the shoulder. Technically, it is important to achieve maximum distension, preferably with capsular rupture, and to utilize cortisone in the fluid injected.

Intraarticular corticosteroids, supervised physiotherapy, or a combination of the two in the treatment of adhesive capsulitis of the shoulder: a placebo-controlled trial

OBJECTIVE

To compare the efficacy of a single intraarticular corticosteroid injection, a supervised physiotherapy program, a combination of the two, and placebo in the treatment of adhesive capsulitis of the shoulder.

METHODS

Ninety-three subjects with adhesive capsulitis of <1 year's duration were randomized to 1 of 4 treatment groups: group 1, corticosteroid injection (triamcinolone hexacetonide 40 mg) performed under fluoroscopic guidance followed by 12 sessions of supervised physiotherapy; group 2, corticosteroid injection alone; group 3, saline injection followed by supervised physiotherapy; or group 4, saline injection alone (placebo group). All subjects were taught a simple home exercise program. Subjects were reassessed after 6 weeks, 3 months, 6 months, and 1 year. The primary outcome measure was improvement in the Shoulder Pain and Disability Index (SPADI) score.

RESULTS

At 6 weeks, the total SPADI scores had improved significantly more in groups 1 and 2 compared with groups 3 and 4 (P = 0.0004). The total range of active and passive motion increased in all groups, with group 1 having significantly greater improvement than the other 3 groups. At 3 months, groups 1 and 2 still showed significantly greater improvement in SPADI scores than group 4. There was no difference between groups 3 and 4 at any of the followup assessments except for greater improvement in the range of shoulder flexion in group 3 at 3 months. At 12 months, all groups had improved to a similar degree with respect to all outcome measures.

CONCLUSION

A single intraarticular injection of corticosteroid administered under fluoroscopy combined with a simple home exercise program is effective in improving shoulder pain and disability in patients with adhesive capsulitis. Adding supervised physiotherapy provides faster improvement in shoulder range of motion. When used alone, supervised physiotherapy is of limited efficacy in the management of adhesive capsulitis.

Corticosteroid injections for shoulder pain

BACKGROUND

While many treatments, including corticosteroid injections in and around the shoulder, are advocated to be of benefit for shoulder pain, few are of proven efficacy. This review of corticosteroid injections for shoulder pain is one in a series of reviews of varying interventions for shoulder disorders.

OBJECTIVES

To determine the efficacy and safety of corticosteroid injections in the treatment of adults with shoulder pain.

SEARCH STRATEGY

MEDLINE, EMBASE, CINAHL, Central and Science Citation Index were searched up to and including June 2002.

SELECTION CRITERIA

Randomised and pseudo-randomised trials in all languages of corticosteroid injections compared to placebo or another intervention, or of varying types and dosages of steroid injection in adults with shoulder pain. Specific exclusions were duration of shoulder pain less than three weeks, rheumatoid arthritis, polymyalgia rheumatica and fracture.

DATA COLLECTION AND ANALYSIS

Trial inclusion and methodological quality was assessed by two independent reviewers according to predetermined criteria. Results are presented separately for rotator cuff disease, adhesive capsulitis, full thickness rotator cuff tear and mixed diagnoses, and, where possible, combined in meta-analysis.

MAIN RESULTS

Twenty-six trials met inclusion criteria. The number, site and dosage of injections varied widely between studies. The number of participants per trial ranged from 20 to 114 (median 52 participants). Methodological quality was variable. For rotator cuff disease, subacromial steroid injection was demonstrated to have a small benefit over placebo in some trials however no benefit of subacromial steroid injection over NSAID was demonstrated based upon the pooled results of three trials. For adhesive capsulitis, two trials suggested a possible early benefit of intra-articular steroid injection over placebo but there was insufficient data for pooling of any of the trials. One trial suggested short-term benefit of intra-articular corticosteroid injection over physiotherapy in the short-term (success at seven weeks RR=1.66 (1.21, 2.28).

REVIEWER'S CONCLUSIONS

Despite many RCTs of corticosteroid injections for shoulder pain, their small sample sizes, variable methodological quality and heterogeneity means that there is little overall evidence to guide treatment. Subacromial corticosteroid injection for rotator cuff disease and intra-articular injection for adhesive capsulitis may be beneficial although their effect may be small and not well-maintained. There is a need for further trials investigating the efficacy of corticosteroid injections for shoulder pain. Other important issues that remain to be clarified include whether the accuracy of needle placement, anatomical site, frequency, dose and type of corticosteroid influences efficacy.

[Physical therapy of frozen shoulder: literature review]

OBJECTIVE

To determine the efficacy of physical treatments in adhesive capsulitis of the shoulder by a systematic review of literature, attempting to perform a meta-analysis from randomised clinical trials.

METHOD

A systematic literature search was conducted to retrieve all randomised controlled trials of physical therapy such as physiotherapy and manipulation, but also arthrographic distension, mobilisation under general anaesthesia or nerve block, arthroscopic distension or arthrolysis, and intra-articular corticoid injections. The main outcome for meta-analysis was the restoration of range of movement between the sixth week and the third month.

RESULTS

Only 16 articles could be selected, and only three about capsular distension were included in a meta-analysis because of the heterogeneity of the criteria assessing the functional results and of the poor methodological value of most of the articles.

DISCUSSION

Some open studies stressed the value of daily manipulations and physiotherapy, intra-articular corticosteroid injections, but their quality was poor or limited. Nothing was written about antalgic drugs to facilitate joint mobilisation, and the use of a thoraco-brachial abduction device between exercises was only quoted. The most refractory cases might need more aggressive interventions: arthrographic distension with local anaesthesia and steroid injection; mobilisation under general or local anaesthesia, specially interscalene brachial plexus block; arthroscopic release. But there was no randomised controlled study comparing these three techniques and it seemed impossible to come to any conclusion about the superiority of one of them. The meta-analysis showed yet that capsular distension with intra-articular corticoid injections was better than corticoid injections alone.

CONCLUSION

This demonstrated the need of a consensus about the criteria of assessment, the time of evaluation, before assessing by randomised clinical trials of good quality their therapeutic value.

Adhesive capsulitis: optimal treatment of 'frozen shoulder'

Idiopathic adhesive capsulitis is an enigmatic shoulder disorder that causes pain and reduced range of motion from joint capsule fibrosis. In most cases, the fibrosis resolves and shoulder function returns to normal or near normal. Physicians' major tasks are to differentiate adhesive capsulitis from rotator cuff dysfunction and other causes of shoulder pain and to assist the patient in choosing appropriate treatment. Conservative therapies include rest, analgesia, and range-of-motion exercises. Other treatments include corticosteroid injections, capsular distention, manipulation under anesthesia, and surgical capsular release.

Interventions for shoulder pain

OBJECTIVES

To review the efficacy of common interventions for shoulder pain.

SEARCH STRATEGY

We searched the Cochrane Musculoskeletal Group trials register, Cochrane Controlled Trials Register, Medline, Embase, Cinahl, and Science Citation Index) up to May 1998, and hand searched major textbooks, bibliographies of relevant literature, the fugitive literature, and the subject indices of relevant journals including: American College of Rheumatology;British College of Rheumatologists; the Biennial Conference of the Manipulative Physiotherapy Association of Australia;International Federation of Manual Therapists conference proceedings; British Orthopaedic Association;and American Orthopaedic Association.

SELECTION CRITERIA

Each identified study was assessed for possible inclusion by two independent reviewers based on the blinded methods sections. The determinants for inclusion were that the trial include an intervention of interest (non-steroidal anti-inflammatory drugs, intra-articular or subacromial glucocorticosteroid injection, oral glucocorticosteroid treatment, physiotherapy, manipulation under anaesthesia, hydrodilatation, or surgery); that treatment allocation was randomized; and that the outcome assessment was blinded.

DATA COLLECTION AND ANALYSIS

Methodological quality was assessed by two independent, blinded reviewers. Data relating to selection criteria, outcome measurement and treatment effect was extracted from the blinded trials. Range of motion scores were entered as degrees of restriction to movement, and all pain and overall effect scores were transformed to 100 point scales. For continuous outcome measures, where standard deviation was not reported it was either calculated from the raw data or converted from standard error of the mean. If neither of these were reported, authors were contacted in an effort to obtain the missing values. Effect sizes were calculated and combined in a pooled analysis if study population, endpoint and intervention were comparable.

MAIN RESULTS

Thirty one trials met inclusion criteria. Mean methodological quality score was 16.8 (9.5 - 22) out of possible score of 40. Selection criteria varied widely even for the same diagnostic label. There was no uniformity in outcome measures used and their measurement properties were rarely reported. Effect sizes for individual trials were small (-1.4 to 3. 0). The results of only three studies investigating rotator cuff tendonitis could be pooled. Benefit of subacromial steroid injection over placebo for improving range of abduction (weighted difference between means (WMD) 35 degrees, 95% CI 14 to 55) was the only positive finding.

REVIEWER'S CONCLUSIONS

There is little evidence to support or refute the efficacy of common interventions for shoulder pain. As well as, the need for further well designed clinical trials, more research is needed to establish a uniform method of defining shoulder disorders and developing outcome measures which are valid, reliable and responsive in these study populations.

Effectiveness of corticosteroid injections versus physiotherapy for treatment of painful stiff shoulder in primary care: randomised trial

OBJECTIVE

To compare the effectiveness of corticosteroid injections with physiotherapy for the treatment of painful stiff shoulder.

DESIGN

Randomised trial.

SETTING

40 general practices.

SUBJECTS

109 patients consulting general practitioners for shoulder pain were enrolled in the trial.

INTERVENTIONS

Patients were randomly allocated to 6 weeks of treatment either with corticosteroid injections (53) or physiotherapy (56).

MAIN OUTCOME MEASURES

Outcome assessments were carried out 3, 7, 13, 26, and 52 weeks after randomisation; some of the assessments were done by an observer blind to treatment allocation. Primary outcome measures were the success of treatment as measured by scores on scales measuring improvement in the main complaint and pain, and improvement in scores on a scale measuring shoulder disability.

RESULTS

At 7 weeks 40 (77%) out of 52 patients treated with injections were considered to be treatment successes compared with 26 (46%) out of 56 treated with physiotherapy (difference between groups 31%, 95% confidence interval 14% to 48%). The difference in improvement favoured those treated with corticosteroids in nearly all outcome measures; these differences were statistically significant. At 26 and 52 weeks differences between the groups were comparatively small. Adverse reactions were generally mild. However, among women receiving treatment with corticosteroids adverse reactions were more troublesome: facial flushing was reported by 9 women and irregular menstrual bleeding by 6, 2 of whom were postmenopausal.

CONCLUSIONS

The beneficial effects of corticosteroid injections administered by general practitioners for treatment of painful stiff shoulder are superior to those of physiotherapy. The differences between the intervention groups were mainly the result of the comparatively faster relief of symptoms that occurred in patients treated with injections. Adverse reactions were generally mild but doctors should be aware of the potential side effects of injections of triamcinolone, particularly in women.

Intra-articular triamcinolone acetonide injection in patients with capsulitis of the shoulder: a comparative study of two dose regimens

BACKGROUND AND PURPOSE

Although corticosteroid injections have been reported to be effective in capsulitis of the shoulder, the optimal dose has not been established. The purpose of this study was to compare relief of symptoms following a lower dose with that following a higher dose of triamcinolone acetonide given intra-articularly.

SUBJECTS

Thirty-two patients were given low dose suspension; 25 patients were given high dose suspension.

METHOD

Randomized, double-blind clinical trial. Each patient was given a course of three injections. Pain, sleep disturbance, functional impairment and passive range of motion (ROM) were assessed at intake and at one, three and six weeks after the initial injection. Data were analysed by independent sample t-tests and nonparametric Mann-Whitney U-tests.

RESULTS

The group which received the 40 mg dose showed significantly greater improvement than the group receiving the 10 mg dose.

CONCLUSIONS

The study shows that in the treatment of frozen shoulder greater symptom relief is obtained with a dose of 40 mg triamcinolone acetonide intra-articularly than with a dose of 10 mg. The effect on pain and sleep disturbance was more marked than on ROM. Intra-articular injections with triamcinolone acetonide appear to be an effective method to obtain symptom relief for patients with painful capsulitis of the shoulder.

Percutaneous treatments of painful shoulder

Percutaneous treatments are useful in two, frequent, painful conditions involving the shoulder. In frozen shoulder syndrome, distention arthrography with intra-articular injection of steroid is used to provide pain relief and to improve joint motion. In rotator cuff tendon calcifications, needle aspiration of calcific deposits is used to treat pain. Surgery should be restricted to failures of needle aspiration. The techniques of these procedures are described and their results are reported.

Comparison of the accuracy of steroid placement with clinical outcome in patients with shoulder symptoms

OBJECTIVE

To study the effect of accuracy on the clinical outcome of local steroid injections to the shoulder.

METHODS

37 patients with shoulder symptoms of at least two months' duration received local injections of a mixture of triamcinolone and radiographic contrast material using a standardised technique. Radiographs of the joint were taken immediately afterwards. Details of the patients' symptoms (assessed by visual analogue scales) and range of movement at the joint were obtained before and two weeks after the injection. At follow up the patients were also assessed by means of a five point global rating scale of maximum and current benefit.

RESULTS

14 of the 38 procedures (37%) were judged to be accurately placed: four of the 14 attempted subacromial injections (29%) and 10 of the 24 attempted glenohumeral injections (42%). There were significant differences in relation to outcome between the accurately placed and the inaccurately placed groups.

CONCLUSIONS

Accuracy of steroid placement by injection in patients with shoulder symptoms may significantly affect the clinical outcome.

The utility of parenteral glucocorticoids in the emergency department

Exogenous glucocorticoids have wide clinical applicability in emergency medicine. Many uses reported for this class of drugs are supported by only anecdotal evidence of efficacy, while others have been proven or disproven by well-designed studies; this evidence is evaluated here. Because adverse effects are relatively common and may be serious after initiation of steroid therapy in the emergency department, it is important for the emergency physician to review systematically the indications, contraindications, and precautions for the use of parenteral glucocorticoids.

The value of shoulder distension arthrography with intraarticular injection of steroid and local anaesthetic: a follow-up study

A series of 51 patients, seen in Leicester, with "frozen shoulder", and referred for arthrographic examination, were assessed both before and after distension arthrography, using air and a low-osmolar contrast media combined with a steroid and local anaesthetic injection. 38 attended for further assessment at up to 6 months later. 16 patients were found to have a rotator cuff tear. There was no significant change in the mean range of active movement in the patients with rotator cuff tears, but symptomatic improvement ensued in 44% of cases. In those found to have no rotator cuff tear, and external rotation of less than 35 degrees, a significant improvement in range of movement was seen. While those with less limitation of external rotation showed no change in their range of movement, they did experience symptomatic improvement in 73% of cases. We conclude that shoulder distension arthrography, with steroid and local anaesthetic injection, may be of symptomatic benefit in patients with frozen shoulder and without a rotator cuff tear, while only those with external rotation of less than 35 degrees are likely to improve their range of motion.
