Porterhouse steak and its anatomic correlation
Porterhouse steak is composed of the Erector spinae muscles and the Psoas muscle. In other words, it is a KC or NY Strip combined with a large Filet mignon.
It is differentiated from the T-bone steak by being cut from a lower section which has a larger filet mignon (Psoas).
The Erector spinae (strip portion of the steak) can be subdivided into 3 separate muscles-
Iliocostalis muscle- Most lateral
Longissimus muscle
Spinalis muscle- Closest to the spine/ spinous process and most medial.
