Are spermatic cord torsion and testicular torsion the same thing?

Sort of.....: Torsion simply means "turning or twisting" any organ that lives at the end of a stalk or pedicle (like an ovary or a testis) can torse. Usually it is the stalk that twists (like the spermatic cord) but it is the testicle that is affected.

Different in...: Spermatic cord torsion is extravaginal with its twisting hinge inside inguinal canal in prenatal or newboens; the commonly discussed testicular torsion is intravaginal with its twisting hinge below external inguinal ring in adolescents and adults with its peak around 15-19.
