Hi Colm,
I can’t remember the last time I was asked to guide this injection.
We are asked to inject adductor origins from time to time, but the actual symphysis is not so common.
It always makes my eyes water !
You can scan the anterior symphysis in the axial plane and bring the needle in fairly steeply like when you do an AC joint. In fact when I think about it the technique is really identical.
We get the needle between the pubic bones and inject.
Like the AC joint you can also turn the transducer 90 degrees and scan in the sagittal plane right through the disk. You can then inject in plane into the middle of the disk.
I don’t have any difference for gender.
If we find that the disk is tight and we can not inject we slowly withdraw the needle until we find a place where injecting is possible. In these cases some of the injection will end up in the symphysis and some will end up in the collagen superficial to it.
Steve.
