Hip and Pelvis Functional Anatomy

A 42 year-old male presents with 3 weeks of pain over right gluteal musculature. He recently noticed weakness in right foot when standing on his tippy-toes. On exam, he has no weakness in dorsiflexors or evertors of the foot. What is the most likely diagnosis?

• Lumbar radiculopathy

• Piriformis syndrome

• Greater trochanteric bursitis

• Sacroiliitis

What is the strongest ligament in the body?

• Iliofemoral ligament

• Pubofemoral ligament

• Ischiofemoral ligament

• Sacroiliac ligament

A 28 year-old resident is attempting to win the PM&R monthly squat challenge. He began noticing a painful “pinch” in his right hip with deep squatting. An astute co-resident points out that he may have femoroacetabular impingement. Assuming they are correct, what muscle groups should be targeted in therapy to treat his FAI?

• Hip adductors and internal rotators

• Hip adductors and external rotators

• Hip abductors and internal rotators

• Hip abductors and external rotators

A 72 year-old female with chronic left hip pain 2/2 osteoarthritis walks into office holding a cane in her right hand. A cane on the contralateral side reduces joint reactive forces  through the affected hip by which mechanism?

• Increasing hip flexor muscular pull

• Moving the center of rotation of the femoroacetabular joint

• Reducing hip abductor muscular pull

• Moving the center of gravity posterior to 2nd sacral vertebra

Which of the following muscle is an internal rotator of the hip?

• Quadratus femoris

• Obturator internus

• Semitendinosus

• Superior gemellus

82 yo f w PMHx of HTN and CAD sustains a fall while walking down her driveway in NYC and fractures her right hip. She undergoes ORIF wo complications. Orthopedic surgeon places partial weight bearing restrictions on right lower extremity. Patient is severely deconditioned and has weak upper extremities but maintains good balance. The appropriate assistive device would be:

• Rolling walker

• Quad cane

• Axillary crutches

• Standard walker

44 yo f patient reports difficulty climbing stairs to her 4th story walkup apartment which has progressively worsened over the last 3 months. She denies a history of low back pain and trauma. A lesion is discovered on MRI of which of nerve?

• Tibial

• Superior gluteal

• Obturator

• Inferior gluteal

Q angle is measured by the angle between intersecting lines drawn through:

• Greater trochanter/center of patella + center of patella/middle of tibia

• Ischial tuberosity/center of patella + center of patella/middle of tibia

• Greater trochanter/center of patella + center of patella/tibial tuberosity

• ASIS/center of patella + center of patella/tibial tuberosity

A 52 y.o. patient was in a MVA and found to have a Hemoglobin of 5 mg/dl. He was stabilized with 2 packs of RBC. He has tenderness and contusions at his left side of the abdomen with a fluctuant swelling of his anterolateral thigh. His US image of his thigh is below. He likely has:

• Hematoma

• Morel-Lavallee lesion

• A lot of subcutaneous tissue

A 26 y.o. resident presents with right gluteal pain that radiates down her posterolateral thigh down to her foot. Her symptoms are worse with prolonged sitting and walking. She denies any back pain. Her exam is notable for full spinal ROM without pain, positive SLR, pain with palpation of the right gluteus, and reproduction of her symptoms with internal rotation of her right leg when extended. What is this maneuver:

• Beatty maneuver

• Pace maneuver

• Freiberg maneuver

• FAIR maneuver
