PAEA Surgery End Of Rotation (EOR) Practice Exam

What type of pain is indicated by passive rotation of a flexed hip?

1. Psoas's

2. Obturator's

3. Gluteus medius

4. Iliac crest

The correct answer is: Obturator's

Passive rotation of a flexed hip typically indicates the presence of obturator-related pain. The obturator internus and externus muscles are located deep in the pelvis and play a role in the medial and lateral rotation of the hip. Specifically, when the hip is flexed and internally rotated, it can exacerbate pain if there is an underlying issue such as obturator nerve entrapment or obturator muscle strain. This type of pain is often assessed during a physical examination for conditions like hip pathology or when evaluating for possible injury or irritation in the obturator region. The reproduction of pain with movement in this manner is a key indicator used by clinicians to localize issues associated with the obturator nerve or muscle groups. Other factors may contribute to hip pain, but the mechanism behind this specific movement correlates directly with the obturator function. For instance, while psoas pain is typically associated with issues in hip flexion or lumbar situations, and gluteus medius pain may relate to abduction or stabilization problems, neither of these would reproduce pain in the same manner as the passive rotation of a flexed hip. Additionally, iliac crest pain is generally localized to the hip or low back and does not present specifically with passive hip rotation. Thus
