Musculoskeletal injections

Different joint and musculoskeletal injections are common in family practice settings and they can offer a lot of benefits for the patient. The hard thing for nurse practitioner students is getting the opportunity to practice because a lot of becoming proficient in this has to do with how often you can practice these. I do see some have difficulty with finding the right spot, and I’ve encountered situations myself where I found it very different. For example, I had a morbidly obese patient who I would see for bilateral knee injections related to her arthritis, but her extreme obesity obscured the normal landmarks I would be able to palpate and visualize in other patients. Have you found any tools or study resources you find helpful in learning to practice where these injections need to be given?
