posterior approach to the glenohumeral joint

Last edited 06/2020

The patient should be seated with his/her back to the operator. The arm should be allowed to relax down by the side of the patient. The position of the anterior coracoid process and the prominent posterior corner of the acromium should be palpated. The needle is then inserted at a site 1cm inferior and 1cm medial to the posterior corner of the acromium. With the examiner's other hand palpating the coracoid process anteriorly the needle should then be directed towards the coracoid process until bone is felt and the articular space is entered.
