The influence of ultrasound guidance in the rate of success of acromioclavicular joint injection: an experimental study on human cadavers

Ultrasound-guided shoulder girdle injections are more accurate and more effective than landmark-guided injections: a systematic review and meta-analysis

“…(3) Two efficacy studies reported blinding of the participants 28 32. (4) Four studies failed to report blinding of the investigator 25 26 34 37. (5) Three studies failed to report the actual number of patients who completed the full study 25 26 30.…”

“…Two studies performed a power analysis prior to the study 34 37. (2) All efficacy studies excluded patients with a prior cortisone injection and intervention, except for two studies which failed to exclude patients with a prior cortisone injection and/or intervention 26 32.…”

“…Another two papers had a weak diagnostic method to confirm the presence of bicipital tendinitis/tendinopathy or adhesive capsulitis (inclusion criteria were based on a clinical finding without a confirmatory imaging of the underlying pathology) 31 32. (4) Four studies failed to report an imaging evaluation of the shoulders prior to the injection 31 34 35 37. (5) All efficacy studies compared the patient demographics at baseline except for one study 26.…”

Degenerative Joint Disease of the Acromioclavicular Joint

“…15 The accuracy of intra-articular injection is improved, however, with the use of ultrasound guidance, which yields an increased frequency of reaching the intra-articular space ( Figure 5). 3,15 Upon follow-up, patients should be asked whether the local anesthetic portion of the injection provided any relief for the hours following the injection as well as whether the corticosteroid portion of the injection provided any relief for the weeks following the injection, as patients with symptomatic AC degeneration can experience the former without the latter. Only 28% of patients report resolved symptoms at 4 weeks after injection and 64% of patients fail to improve after an injection.…”

Clinical Aspects of Regenerative Medicine

“…It has been shown that ultrasound-guided knee injections have improved accuracy compared with anatomical guidance (95.8% versus 77.8%), with corresponding improved patient clinical outcomes and costeffectiveness [79,80]. Similarly, positive outcomes using ultrasound guidance have been reported with injections in other patient joints [81,82]. The ideal injection technique for knee OA has not been studied; whether best to solely target the suprapatellar recess or to target the surrounding structures, such as the meniscus, collateral ligaments, iliotibial band, etc., as well, remains unclear.…”
