Obturator Externus Anatomy | The Deep Hip Stabilizer Everyone Forgets

The Obturator Externus is one of the Deep 6 hip external rotators — but it’s also one of the easiest muscles in the group to forget. Unlike most of the other deep hip rotators, Obturator Externus sits more anterior and inferior, originating from the external surface of the obturator foramen and obturator membrane before traveling underneath the femoral neck to insert into the trochanteric fossa. In this Anatomy Breakdown, we cover: 𖤓 Obturator Externus origin 𖤓 Obturator Externus insertion 𖤓 Obturator Externus innervation 𖤓 Obturator Externus function 𖤓 Hip external rotation 𖤓 Femoral head stability 𖤓 Why this muscle may matter for dancers, soccer players, hockey players, martial artists, gymnasts, and rotational athletes Clinically, Obturator Externus is more than just another external rotator. Because of its position underneath the femoral neck, it may play an important role in inferior hip stability, deep rotational control, and femoral head mechanics — especially in high-demand positions like turnout, cutting, kicking, pivoting, and end-range hip rotation.
