I went to Montefiore. Had 1-2 days per week of dedicated ultrasound clinic, plus ultrasound workshops with the residents weekly. Other clinics had ultrasound available if we needed it for point-of-care. I did every kind of injection - SI joint, piriformis with sciatic hydrodissection, plantar fascia, trigger finger, cubital tunnel, etc, and of course the bread and butter shoulder, knee, hip. We also rotated in the spasticity clinic and used ultrasound there for botox or nerve blocks.
I think it is different now, but I also had 1 day per week of fluoroscopy. The Pain Medicine fellowship grew, so there may be less opportunity for the Sports fellows. But as far as personal experience, I did epidurals, medial branch blocks, SI Joint.
Unfortunately, orthobiologics was limited. Did Tenex and PRP. Of course, they are sexy, but technical skills are the same as any other injection.
