English to Spanish Medical Medical (general)

Hi all,

I am translating some medical reports and I am struggling with the term "medial hamstring", which is used many times in the documents, for example in an MRI report:

Clinical History:
Pain left hip
Hip arthroscopy 4/16
no groin pain but pain over medial hamstrings
? Hamstring injury

I would normally translate "hamstring" as "musculo isquiotibial" but it's that "medial" I don't know how to translate. Fernando Navarro's Libro Rojo says:

hamstring (o hamstring tendons). Este nombre dan en inglés a los tendones isquiotibiales o tendones poplíteos, que limitan a ambos lados el espacio poplíteo. Llaman, pues, medial hamstring a los dos tendones de los músculos semimembranoso y semitendinoso, y lateral hamstring al tendón del músculo bíceps femoral (o bíceps crural). ● hamstring injury (lesión de los isquiotibiales), hamstring muscles (músculos isquiotibiales; esto es, los músculos semimembranoso, semitendinoso y bíceps femoral [o bíceps crural]).


So they give an explanation of what it refers to but not an actual translation. Is there not a way to say it in Spanish? Musculo isquiotibial medio? Central?

Thank you in advance,
