APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -The pubofemoral ligament limits hip abduction and extension.

Detailed explanation-2: -The iliofemoral ligament provided primary external rotation restraint in all hip positions, and both primary internal and external rotation restraint when the hip was extended or in neutral hip flexion (Fig.

Detailed explanation-3: -Those muscles include your adductors as well as your gluteus medius and minimus. Both groups of muscles can limit hip external rotation and the adductors can limit both hip internal and hip external rotation, depending on which adductor you are referring to.

Detailed explanation-4: -At the point of limitation of true right hip flexion, any further flexion of the thigh must entail rotation of the pelvis: this means the left hip will be extending so long as the left thigh remains lying on the couch surface.
