Dr. Jess Mason presents the posterior approach for shoulder intra-articular injections. The same approach can be used for arthrocentesis. This technique is very similar to a subacromial bursa injection, so watch that video too and choose the right one for your needs. Procedure performed by Dr. Leann Mainis.

Can you please explain the difference between this and the bursa injection? I don't see where the difference is to be honest between the two videos. Thank you.

They are very similar. The joint injection is intraarticular, so the angle of the needle is aiming towards the coracoid process, the needle typically goes in deeper (assuming normal habitus) and there's often a pop sensation you feel with insertion. You do this to either inject medication for intraarticular pain or to aspirate fluid for suspected septic arthritis.
The bursa is outside the joint and more superior. The needle is more superficial and is aimed above the humeral head. You would do this for a shoulder impingement syndrome for pain relief or remove fluid if you think the bursa is infected.

what gauge/type needle do you prefer for shoulder reductions and how deep do you inject?
