“Anatomy is to physiology as geography is to history; it describes the theatre of events.”
The anatomy is quite similar in the musculoskeletal apparatus. Just think at the correlations between shoulder and hip antomy; the gluteus medius and gluteus minimus externally rotate the thigh and a bursa separates the tendons from the surface of the trochanter over which they glide (that anatomy ring a bell with you?). Performing an ultrasound study at the trochanter site, you can find lots of similarities with the shoulder anatomy.

Don’t forget these similarities, regarding both to anatomy and function, because it will be helpful for your clinical and ultrasound evaluation.
