Forty-eight patients with frozen shoulder for less than six months were assigned at random to receive three shoulder injections into the subacromial bursa or glenohumeral joint at weekly intervals. The treatment groups were (1) intra-articular methylprednisolone and lidocaine, (2) intrabursal methylprednisolone and lidocaine, (3) intra-articular lidocaine, (4) intrabursal lidocaine. The same physical therapy program was carried out for all patients. Assessments of pain and range of motion were performed by a physical therapist who was uninformed about the nature of the injection therapy. There was no significant difference in outcome between intrabursal injection and intra-articular injection. Injection of steroid with lidocaine had no advantage over lidocaine alone in restoring shoulder motion, but partial, transient pain relief occurred in two thirds of the steroid-treated patients. To compare the effectiveness of ultrasound guided corticosteroid injection in the subacromial bursa with systemic corticosteroid injection in patients with rotator cuff disease.
                Double blind randomised clinical trial.
                Outpatient clinic of a physical medicine and rehabilitation department in Oslo, Norway. Patients 106 patients with rotator cuff disease lasting at least three months.
                Ultrasound guided corticosteroid and lidocaine injection in the subacromial bursa and lidocaine injection in the gluteal region (local group); corticosteroid and lidocaine injection in the gluteal region and ultrasound guided lidocaine injection in the subacromial bursa (systemic group).
                Difference in improvement in the overall shoulder pain and disability index score after six weeks.
                Six weeks after the intervention, the mean difference in improvement in overall shoulder pain and disability index score between the local group and the systemic group was -5.2 (95% confidence interval -13.9 to 3.5); it was -4.1 (-12.3 to 4.1, P=0.32) after adjustment for baseline score. A small but statistically significant difference in improvement between groups occurred in favour of the local group for two secondary outcome measures: the Western Ontario rotator cuff index (8.1, 0.7 to 15.6) and change in main complaint (2.0, 0 to 4).
                No important differences in short term outcomes were found between local ultrasound guided corticosteroid injection and systemic corticosteroid injection in rotator cuff disease.
                Clinical trials NCT00640575. Local corticosteroid injections, commonly accepted by rheumatologists to be effective treating painful shoulder, have shown controversial results. High frequency ultrasonography is an accurate and safe imaging modality for guiding musculoskeletal injections. We prospectively compared the short term response to randomized blind injection versus sonographic-guided injection of local corticosteroid in patients with painful shoulder.
                We studied 41 consecutive patients with painful shoulder. Patients with previous trauma or chronic inflammatory arthritis were excluded. No patient had received previous physiotherapy or local steroid injection in the shoulder. Patients were randomized to receive either a blind subacromial injection of 20 mg triamcinolone (Group 1, n = 20) or a sonographic guided injection of 20 mg triamcinolone (Group 2, n = 21) by the same rheumatologist blinded to the clinical evaluation. In both groups we recorded shoulder abnormalities and the location of the steroid postinjection by ultrasound. Each patient was clinically assessed within 5 days before injection and 6 weeks after injection by another rheumatologist without knowledge of the injection technique performed. Clinical assessment included demographic and clinical data, a visual analog scale (VAS) for pain (0-100), the Shoulder Function Assessment (SFA) scale (0-70), and postinjection adverse effects. No patient received physical therapy during the followup period. Initially, demographic, clinical, and ultrasonographic findings in both groups showed no significant differences.
                Six weeks after injection, the VAS and the SFA score showed a significantly greater improvement in Group 2 compared with Group 1 (mean VAS score change 34.9 for Group 2 vs 7.1 for Group 1, p < 0.001; and mean SFA score change 15 for Group 2 vs 5.6 for Group 1, p = 0.012). One patient in Group 1 reported mild postinjection adverse effects.
                We suggest that sonographic-guided corticosteroid injections should be indicated, at least, in patients with poor response to previous blind injection to ensure accurate medication placement in order to improve therapeutic effectiveness. Seventy seven patients with soft tissue shoulder lesions including adhesive capsulitis and disorders of the rotator cuff and acromioclavicular joint were admitted to a trial comparing two different methods of corticosteroid injection with local anaesthetic in a randomly allocated double blind study. The method of anatomical injection after diagnosis by the technique of selective tissue tension gave 60% success compared with the method using tender or trigger point localisation, giving 20% success (p less than 0.001). Adhesive capsulitis is a common musculoskeletal disorder mainly affecting middle aged adults. It is associated with generalized pain and tenderness in the shoulder joint with severe loss of active and passive ranges of motion in all planes. The aim of this study was to compare the efficacy of local steroid injection and physical therapy measures for treating this disorder. Ten male and 10 female patients were enrolled in the study. The patients were divided randomly into two groups and treated with either 40 mg methylprednisolone acetate injection with local anesthetic (group A) or physical therapy measures plus nonsteroidal anti-inflammatory drugs (group B). The mean ages of the patients were 55.6+/-12.2 years in group A and 56.4+/-7.1 years in group B. Clinical assessment was performed on initial visit and at the 2nd and 12th weeks. Active and passive range of motion was recorded and the visual analogue scale was used to evaluate pain intensity. At initial visit, these data in both groups of patients were not statistically different. Although both treatment regimens resulted in significant improvement in range of motion, the differences between mean external rotation at the 2nd and 12th weeks were not statistically significant in either group. The improvement in range of motion at the end of the study was similar in both groups (P>0.05). All patients reported improvement during the study. The differences between mean VAS scores at the 2nd and 12th weeks were statistically significant in both groups. In conclusion, local steroid injection therapy was found to be as effective as physical therapy for the treatment of adhesive capsulitis. A double-blind, prospective study of 45 patients with adhesive capsulitis of the shoulder compared the therapeutic efficacy of distensive and nondistensive arthrography in combination with the intra-articular injection of corticosteroids. After 1 and 3 months there was no significant difference between the two treatments in the degree of pain or of limitation of movement experienced by the patients. More than 80% of the patients who experienced pain at rest and nocturnal pain improved under both treatment regimens. Scapulohumeral mobility increased significantly but only partially within the first month of treatment. Articular capacity and the duration of symptoms before treatment were of no prognostic value. To study the effect of manipulating a shoulder with adhesive capsulitis (frozen shoulder) under anesthesia with and without corticosteroid injection.
                Randomized trial.
                Hospital.
                Twenty-four patients referred for manipulation of a frozen shoulder.
                The patients were randomized into 2 groups. One group received an injection of corticosteroid and manipulation; the other was only administered manipulation during anesthesia.
                The degree of shoulder mobility and pain before and after the manipulation.
                Manipulation under anesthesia increased the mobility of the affected shoulder. Injection with lidocaine and betamethason did not enhance the effect of the manipulation.
                Manipulation under anesthesia without intraarticular corticosteroids is recommended as the therapy for frozen shoulder. A prospective, randomized, controlled, double-blind clinical study was performed to determine the short-term efficacy of subacromial injection of corticosteroids for the treatment of subacromial impingement syndrome. Forty patients were randomized to receive either six milliliters of 1 per cent lidocaine without epinephrine (the control group) or two milliliters containing forty milligrams of triamcinolone acetonide per milliliter with four milliliters of 1 per cent lidocaine without epinephrine (the corticosteroid group). The patients were re-examined serially until completion of the study. Nineteen patients, whose mean age was fifty-six years (range, thirty-two to eighty years), were randomized to the corticosteroid group, and twenty-one patients, whose mean age was fifty-seven years (range, thirty-two to eighty-one years), were randomized to the control group. The mean duration of symptoms before the injection was eight months for both groups. Eighteen patients in the corticosteroid group and nineteen patients in the control group had moderate or severe pain before the injection. At the most recent follow-up evaluation, at a mean of thirty-three weeks for the corticosteroid group and twenty-eight weeks for the control group, three patients in the corticosteroid group had moderate or severe pain, compared with fifteen patients in the control group. The mean active range of forward elevation and external rotation improved by 24 and 11 degrees, respectively, for the corticosteroid group and by 10 and 5 degrees, respectively, for the control group. We concluded that subacromial injection of corticosteroids is an effective short-term therapy for the treatment of symptomatic subacromial impingement syndrome. The use of such injections can substantially decrease pain and increase the range of motion of the shoulder. Using a prospective, double blind, double dummy protocol, we compared the efficacy of subacromial injection of 40 mg of triamcinalone acetonide versus oral indomethacin, 100 mg/day, in 40 patients with acute rotator cuff tendinitis. Repeat injection and refill of medication was given after 3 weeks, if necessary. At 6 weeks, there was no significant difference between the 2 groups with respect to the percentage of patients who improved (60 vs 66%) or the magnitude of the change of pain and motion variables. This study suggests that there is essentially no difference in the short term efficacy of oral nonsteroidal therapy compared to local corticosteroid injection(s) in the treatment of rotator cuff tendinitis.
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.
