Pelvic Girdle and Hip Joint Practice Exam

What would happen if the round ligament of the femur were completely torn?

• The head of the femur degenerates due to avascular necrosis

• The femur dislocates laterally

• The hip joint becomes hypermobile

• There is a loss of sensory innervation to the femoral head

Which of the ligaments of the hip limit excessive extension?

• Ligamentum teres and sacrotuberous ligament

• Transverse acetabular and round ligament

• Superior and inferior bands of iliofemoral, pubofemoral, ischiofemoral

• Inguinal ligament and iliopectineal ligament

What nerves provide sensory innervation to the hip joint?

• Tibial, common fibular, sural

• Femoral, obturator, sciatic, superior gluteal, and inferior gluteal

• Pudendal, genitofemoral, ilioinguinal, and perineal

• Lateral femoral cutaneous and saphenous

The trochanteric bursa lies between what structures?

• Greater trochanter and iliotibial band

• Greater trochanter and gluteus maximus

• Lesser trochanter and iliopsoas

• Greater trochanter and piriformis

The ischial bursa lies between what structures?

• Ischial spine and sacrotuberous ligament

• Ischial tuberosity and gluteus maximus

• Ischial tuberosity and piriformis

• Ischial ramus and obturator externus

What is the relationship of the sciatic nerve and the superior and inferior gluteal nerves and vessels to the piriformis muscle?

• All nerves pass superior to the piriformis

• Sciatic nerve pierces the piriformis while others pass inferior to the piriformis muscle

• Superior gluteal nerves and vessels enter above; inferior gluteal nerves and vessels enter below the piriformis

• Sciatic and inferior gluteal nerves and vessels pass superior to the piriformis, while the superior gluteal nerves and vessels pass inferiorly

Which gluteal muscle(s) abduct and internally rotate?

• Gluteus maximus and piriformis

• Gluteus medius and minimus

• Quadratus femoris and obturator internus

• Tensor fasciae latae only

Which gluteal muscle(s) extend and externally rotate?

• Gluteus minimus

• Piriformis

• Gluteus maximus

• Gluteus medius

Which gluteal muscle(s) externally rotate?

• Gluteus medius and minimus

• Tensor fasciae latae

• Gluteus maximus, piriformis, quadratus femoris, superior and inferior gemelli, internal and external obturators

• Adductor longus, piriformis, quadratus lumborum, gluteus medius, adductor magnus, and tensor fasciae latae

Damage to the superior gluteal nerve will affect which muscles?

• Gluteus maximus only

• Piriformis and quadratus femoris

• Gluteus medius and minimus, and tensor fasciae latae

• Obturator internus and externus
