Ultrasonography Guided Glenohumeral Injection Using an Anterior Approach: A Cadaveric Study

ABSTRACT

OBJECTIVE: To assess the accuracy and confidence of the glenohumeral joint injection using an anterior approach in cadavers. METHOD: Eight shoulders from six cadavers were placed supine with arm abduction and external rotation. A single physiatrist performed all the ultrasonography guided injection using an anterior approach. A twenty-one gauge needle was placed into shoulder and intraarticular position was verified by small injection of blue dye. And then the anatomic dissection was done. RESULTS: Seven out of eight (87.5%) were judged to be accurately placed by the anatomic section. In one case, the needle tip was placed in supraglenoid space. In one of the seven accurate cases, the needle traversed the long head tendon of biceps muscle. Confidence of the injections was 87.5%. CONCLUSION: Ultrasonography guided glenohumeral injection using an anterior approach was efficient and safe.
