Medial border of the scapula
Margo medialis scapulae
Reviewed by Dr. Ryan Rietz, D.P.T. and Dr. John Breyman, D.C.
The medial border is the long inner edge of the shoulder blade, running roughly parallel to the spine a few centimetres out from it. It is a tug-of-war line. The rhomboids insert along it and the levator scapulae attaches at its upper corner, both pulling the blade inwards and upwards; the serratus anterior grips its front surface from the ribs and pulls it forwards and around. When a shoulder blade wings away from the ribcage, this is the edge that lifts.
