FIG. 25.15 Biceps Tendon Sheath Injection: Rotator Interval Approach. A 44-year-old woman with anterior shoulder pain. (A) Gray-scale
ultrasound image obtained slightly oblique to the intraarticular biceps tendon (arrow). The greater tuberosity (gt), humeral head (hh), and deltoid (D)
are labeled. (B) A 25-gauge needle is positioned using a short-axis lateral approach adjacent to the margin of the biceps tendon within the rotator
interval. The tip of the needle is indicated (arrow). A test injection with anesthetic is performed to ensure appropriate needle position. Fluid should
not accumulate by the needle tip and the needle position should be adjusted accordingly. (C) Short-axis view of the biceps tendon within the
sheath before needle placement and injection. The tendon (arrow) and bicipital groove (BG) are labeled. (D) Postinjection image at approximately
the same anatomic level as (C) depicting the distended biceps tendon sheath. See also Video 25.2.

FIG. 25.16 Ultrasound-Guided Iliopsoas Bursa Injection for Pain Relief. This 66-year-old woman with a total hip arthroplasty had developed
pain with hip lexion. (A) Preinjection image shows 22-gauge spinal needle (N) positioned deep to the tendon (T) at the level of the iliopectineal
eminence (e), using a short-axis approach. fa, Femoral artery; fn, femoral nerve. (B) After injection and needle removal, luid surrounds the tendon
within the distended iliopsoas bursa (arrow).
