MCQs of Gluteal Region, Posterior Thigh & Hip
- During recovery from a gunshot wound of the right pelvis, the patient notices a lurch in his gait. When he lifts his left foot off of the ground, his pelvis dips down on the left side. The nerve that appears to have been injured is the:
nerve to piriformis
nerve to obturator internus
superior gluteal nerve
- The team doctor tells a football player that he has “a pulled hamstring” muscle. This results from a tearing of the origin of a hamstring muscle from the:
posterior gluteal line
- If the head of the femur is dislocated postero-medially, compression of which nerve is likely to result?
- What muscle passes through the lesser sciatic foramen?
- In order to avoid injury to the sciatic nerve, intramuscular injections should be given in which quadrant of the buttock?
- The femoral artery enters the popliteal fossa (becoming the popliteal artery) by passing through the:
- The short head of biceps femoris muscle is innervated by which nerve?
- As a patient with paralyzed gluteus medius and minimus muscles on the left side attempts to stand on the left limb only, the right side of the pelvis typically:
- When the femur is fractured, the broken distal end often turns posteriorly to enter the popliteal fossa due to muscle traction. Because of its position deepest in the fossa, which structure is most vulnerable to laceration?
Common fibular n.
Lesser saphenous v.
- The deep femoral artery is the principle blood source for the muscles in which compartment of the thigh?
- After suffering a deep stab wound in the medial upper quadrant of the right buttock, an emergency room patient found walking to be very difficult. The basic problem was that, during stepping, her left hip sagged down as soon as the left foot was lifted off the ground to swing forward. What nerve was damaged?
- A fracture of the ischial tuberosity might be expected to most directly affect the muscles that produce which lower limb movement?
Abduction at the hip
Adduction at the hip
Extension at the knee
Flexion at the hip
Flexion at the knee
- When, in approximately 12% of people, the common fibular nerve passes through the piriformis muscle, the nerve may be compressed. This would affect part of which muscle?
- An elderly patient complains of difficulty in walking up stairs. Tests by her doctor reveal weakness in extension at her hip, but no change in hip flexion, or flexion or extension of the knee. Based upon these results, what muscle is most likely not functioning properly.
- Weakness in climbing stairs or jumping would indicate a lesion of which nerve?
- During surgical repair of a popliteal artery aneurism, ligation of the femoral artery at mid-thigh would not interrupt supply to the hamstring muscles because the
Genicular anastomosis ensures blood supply to the posterior thigh
Cruciate anastomosis ensures blood supply to the posterior thigh
Perforating branches of the deep femoral artery supply the posterior thigh
Obturator artery supplies the posterior thigh
Anterior and posterior femoral circumflex arteries anastomose with the inferior gluteal artery
- The medial thigh muscles rotate the femur medially, counterbalanced by muscles of the _____________ thigh, including the ___________ muscle, which rotates the femur laterally.
Lateral; tensor fasciae latae
Anterior; rectus femoris
Posterior; biceps femoris
Posterior; quadriceps femoris
- Following a major operation, a patient was placed on a course of antibiotics which were delivered via intramuscular injection to the buttocks. After one injection in the right buttock, the patient complained of more pain than usual in the region of the injection. Later, as he was walking in the hall, the nurse noticed that he had a limp that had not been present before–his left hip dropped every time he lifted his left foot off the floor. Which nerve had been injured by the injection?
- The hamstrings muscles are supplied by branches of which artery?
- Of the branches of the internal iliac artery, the one exiting from the greater sciatic foramen superior to the piriformis muscle is the:
Internal pudendal artery
Lateral sacral artery
Superior gluteal artery
- Because of its muscle attachments, a fracture to the ischial tuberosity would affect which movement of the lower limb?
Abduction of the thigh
Dorsiflexion of the foot
Extension of the leg
Flexion of the leg
Flexion of the thigh
- When the distal femur is fractured, the sharp broken ends of the bone often damage the structure that lies closest to the femur in the popliteal fossa, i.e., the:
Descending genicular artery
Greater saphenous vein
- In a hunting accident, an arrow pierces the mid-calf of a hunter. A major artery is lacerated in the posterior leg, and you notice that the sole of his foot is cold and pale. The dorsum of the foot is warm and normally colored. The artery that seems to be injured is the:
posterior tibial artery
medial plantar artery
- A patient complains of localized pain in a swollen lower calf and cannot strongly plantar flex his foot. What tendon may have ruptured?
flexor digitorum longus
flexor hallucis longus
- A tennis player feels a “pop” in her calf as she is playing. Her calf becomes tender and there is some slight amount of swelling. Upon examination, her physician informs her that she has ruptured the slender tendon of a small muscle that attaches to the calcaneus. She has apparently ruptured the:
- A football player tears his calcaneal tendon. You would expect to find weakness in:
dorsifiexion of the foot
eversion of the foot
extension of the knee
inversion of the foot
plantarflexion of the foot
- While on vacation in Florida following her final exams, a scuba diving medical student is accidentally speared by her diving partner. The end of the spear passes medial to lateral, posterior to the medial malleolus. It severs an artery there, which is the:
- A patient with painful swelling in the distal calf cannot plantar flex at the ankle with any power. Which tendon was likely ruptured?
Extensor digitorum longus
Extensor hallucis longus
