Shoulder Injection

Video Transcription

This picture demonstrates the surface anatomy with the acromion, the clavicle, and the coracoid. The most common injection is into the subacromial bursa. This can be achieved through a posterior portal, which is two centimeters medial and inferior to the posterior lateral corner of the acromion. The needle is angled superiorly and laterally towards the anterior lateral corner of the acromion as shown in the picture. The subacromial bursa can also be injected laterally as shown. The AC joint has different morphology and can be injected from superior or anterior. It is important to recognize the morphology according to the x-ray and angle the needle accordingly. This picture demonstrates the anterior approach to injecting the AC joint, adjusting the needle as required.
