Accuracy of the biceps tendon sheath injection: ultrasound-guided or unguided injection? A randomized controlled trial

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

“…Additionally, five more studies did not report the randomisation method used 25 26 31 33 34. (2) The allocation concealment method was reported in three studies 29 30 36.…”

“…(II) Limitations related to patient selection and sample size (table 3-II) : (1) Small sample sizes (10–15 participants in each group) were noted in two studies 33 35. Two studies performed a power analysis prior to the study 34 37.…”

“…(5) All efficacy studies compared the patient demographics at baseline except for one study 26. One study had significantly older participants in the landmark group compared to the US group 33. Two cadaver studies failed to report cadaver demographics (body mass index) 34 37.…”

Musculoskeletal Ultrasound in Physical Medicine and Rehabilitation

“…Although there are few absolute indications for the performance of ultrasound-guided interventional procedures, studies have clearly demonstrated that needle placement is more accurate with image guidance, specifically ultrasound, when compared to anatomical landmark or unguided techniques at a variety of anatomical locations [8][9][10][11][12][13]. The data are conflicting whether this translates into improved clinical efficacy [9,[14][15][16].…”

“…The emergence of these new treatments, combined with the needle tenotomy techniques, have been made possible by the ability to visualize the degenerative tendon, perform percutaneous needling of the tendon and accurately place the injectate into the desired area.
