Spot Delt injections?

[!@#$%^&]

I know how to do regular delt shots, in the medial delt. Now if i wanted to hit the posterior head (rear) how would i go about doing this? Its a pretty small spot to be hitting. Where about on the rear head would i stick the needle? What needle length is recommended?

I use 25g 1". I lean my arm on a table and look over my shoulder or into a mirror. Rather than "reach around" (back off, Dr VJ!), I reach over the TOP of the shoulder and inject downward into the posterior head. Works like a charm, although it's a little tough to conceptualize and describe.
