Abstract

Sonography and specific shoulder positions allow for injections into both the long head of the biceps tendon sheath (LHBTS) and the subacromial space (SS) with one needlestick. We validated this technique using cadavers. An experienced proceduralist injected latex solution into 12 unembalmed cadaveric shoulders, aiming for the LHBTS and SS, using an ultrasound-guided injection technique that employs a single-needle entry point. An experience surgeon dissected each specimen and graded latex location as: (1) completely accurate (in both the SS and LHBTS); (2) partially accurate (in either the SS or LHBTS); (3) accurate with overflow (in both locations, but also elsewhere); (4) partially accurate with overflow (in either location, but also somewhere else); or (5) completely inaccurate (no latex in either location). All 12 ultrasound-guided injections using the technique accurately placed latex into both LHBTS and SS (100% accuracy). Latex was also found in adjacent regions after two (17%) injections: one within the shoulder joint and one within the deltoid musculature. This newly described technique allows highly accurate access to the LHBTS and SS with single-needle entry. This technique could become a favored alternative to subjecting patients to two needlesticks and preparing separate injections to address often concomitant pathologies.
