A 63-year-old female patient says that she has pain in her groin and upper thigh. Upon examination, you palpate a lump located below the inguinal ligament lateral to its attachment to the pubic tubercle. You suspect that this may be a hernia passing through the: femoral canal adductor hiatus obturator canal deep inguinal ring superficial inguinal ring
The femoral canal contains the:
Deep inguinal lymph node(s) Femoral artery Femoral nerve Femoral vein Ilioinguinal nerve
Which movement would fail in case of paralysis of the quadriceps femoris muscle?
Adduction at the hip Extension at the hip Extension at the knee Flexion at the knee Medial rotation at the knee
Which structure does NOT enter or leave the inguinal region by passing deep to the inguinal ligament?
Femoral artery Femoral nerve Femoral vein Psoas major muscle Round ligament of the uterus
An elderly woman was found to have a hernial sac in the right femoral triangle and a marked weakness in adduction at the right hip joint. Which nerve was likely compressed by this herniation?
Femoral Inferior gluteal Obturator Pudendal Sciatic
When walking, the action of the iliopsoas muscle results in what motion at the hip joint?
Abduction Adduction Extension Flexion Medial rotation
The pulse of the femoral artery is best felt at which superficial reference point?
Anterior to the ankle joint Femoral triangle Mid-thigh Popliteal fossa Right lateral portion of the hypogastrium
If the femoral artery is occluded at the beginning of the adductor canal, which artery could help provide viability to the leg through collateral circulation?
Descending branch of the lateral circumflex femoral Descending genicular First perforating branch of the deep femoral Medial circumflex femoral Obturator
At which site could one expect to enter the femoral vein with a simple percutaneous (through the
skin) introduction of an instrument?
Above the middle of the inguinal ligament Lateral to the femoral arterial pulse Lateral to the pubic tubercle Medial to the femoral arterial pulse Medial to the pubic tubercle
What anterior thigh muscle must be retracted to expose the adductor canal and its contents?
Adductor magnus Gracilis Rectus femoris Sartorius Vastus intermedius
A serious complication of fractures of the femoral neck is avascular necrosis of the femoral head.
This usually results from rupture of which artery?
Acetabular branch of obturator Deep circumflex iliac Descending branch of lateral circumflex femoral Medial circumflex femoral Second perforating branch of lateral circumflex
A ruptured aneurysm in the most proximal portion of the deep femoral artery would result in a hematoma located initially in the:
Adductor canal. Femoral canal. Femoral triangle. Inguinal canal. Popliteal fossa.
Following a penetrating injury to the left femoral triangle, a patient related that walking was virtually impossible because at every step the left knee collapsed into flexion. This history suggests paralysis of which muscle?
Adductor magnus. Biceps femoris. Gluteus maximus. Quadriceps femoris. Sartorius.
A patient with a tuberculous abscess (localized collection of pus) on the iliopsoas muscle in the femoral triangle presented impaired flexion of the thigh and extension of the leg. Which of the following nerves was likely involved?
femoral inferior gluteal obturator sciatic superior gluteal
An obturator hernia that compresses the obturator nerve in the obturator canal may affect the function of all of the following muscles EXCEPT:
Adductor brevis Adductor longus Gracilis Obturator externus Pectineus
Childhood immunizations are sometimes given via intramuscular injections into the quadriceps muscles of the anterior thigh. At the mid-thigh level, a needle passing into the space deep to the sartorius muscle might pierce the femoral vessels as they lie in the:
Adductor canal Adductor hiatus Adductor triangle Femoral canal Femoral ring
A female patient complains of pain in her groin region that increases with coughing. An MRI reveals a loop of ilium passing inferiorly, posterior to the superior pubic ramus. What type of hernia is this? obturator femoral direct inguinal indirect inguinal lumbar
During a surgical procedure in which the lower abdominal wall has been opened, the retractor blades damaged a nerve lying between the iliacus and psoas major muscles. The patient has weakened hip flexion and an inability to extend the knee, as well as analgesia on the anterior thigh and medial leg. What nerve has been compressed?
obturator femoral sciatic tibial common fibular
Which of the following is NOT located within the adductor canal?
Saphenous nerve Femoral artery Nerve to vastus medialis Femoral vein Deep femoral artery
Inability to extend the knee and loss of cutaneous sensation over the anterior surface of the thigh would indicate a lesion or compression of the: Superior gluteal nerve Lateral femoral cutaneous nerve Sciatic nerve Femoral nerve Obturator nerve
Which statement is true?
The femoral artery lies medial to the femoral vein The femoral vein lies medial to the femoral artery The external iliac veins join to form the inferior vena cava The inferior vena cava can not be imaged radiographically A and C
Blood flow around an occlusion of the femoral (superficial femoral) artery at the apex of the femoral triangle could be provided by:
Anterior tibial recurrent Descending branch of the lateral circumflex femoral Descending genicular Medial circumflex femoral Perforating branches of the deep femoral
After suffering a penetrating injury in the left femoral triangle, a patient was unable to walk normally because her left knee collapsed into flexion upon weight bearing. The nerve to which muscle was damaged?
Adductor magnus Biceps femoris Gluteus maximus Gluteus medius Quadriceps femoris
"Scissor gait" is a condition in which one limb crosses in front of the other during stepping as a result of powerful hip adduction caused by continuous, unwanted nerve activity. What is the nerve involved in this condition?
Femoral Inferior gluteal Obturator Tibial
In the middle third of the thigh, the superficial and deep femoral arteries are separated by:
Adductor longus Adductor magnus Gracilis Pectineus Vastus medialis
Fracture of the femoral neck may lead to avascular necrosis of the femoral head due to the interruption of which artery?
First perforating branch of the deep femoral Inferior epigastric Internal pudendal Lateral circumflex femoral Medial circumflex femoral
Following surgical opening of the adductor canal, a patient experienced a loss of cutaneous sensation of the medial side of the leg. Which nerve was cut? Ilioinguinal Femoral Obturator Medial sural cutaneous Saphenous
