Anterior& Middle Thigh Published on August 30, 2020 by ehudspeth Thigh, Gluteal Region, & Popliteal Fossa You are on rotations when an attending asks you to scrub in for an ACL repair surgery. In order to perform the surgery while also minimizing the loss of blood flow to the leg, the surgeon should ligate which of the following arteries? Superior medial genicular Popliteal artery just superior to the level of the ACL Inferior lateral genicular Inferior medial genicular Middle genicular Which of the following is NOT a border of the popliteal fossa? Semitendinosus Biceps Femoris Medial Head of Gastrocnemius Lateral head of gastrocnemius and plantaris Adductor magnus A patient presents with bruising on the posterior thigh/gluteal region and severe pain upon extension of the hip. You take an x-ray and acquire the image shown below. Which of the following best describes the injury exhibited by the patient? A hamstring strain which caused a subsequent avulsion fracture of the ischial tuberosity A quadriceps strain which caused a subsequent avulsion fracture of the ischial tuberosity A gluteal strain which caused a subsequent avulsion fracture of the ischial tuberosity A hamstring strain which caused a subsequent avulsion fracture of the ischial spine A gluteal strain which caused a subsequent avulsion fracture of the gluteal tuberosity A patient with osteoarthritis walks into your office. Before your exam even starts you see her walking to the exam room and notice her hip dropping to one side. What nerve is injured? Sciatic Nerve Superior Gluteal Nerve Inferior Gluteal Nerve Anterior Rami branches of S1 and S2 Nerve to Quadratus femoris An attending tries to embarrass you in front of a patient by asking you the best place to insert a needle when giving an intragluteal injection. But because you went to ARCOM, you can confidently say the needle should be placed: Superomedial Quadrant to avoid the Sciatic Nerve Suprerolateral Quadrant to avoid the Common Fibular Nerve Superolateral Quadrant to avoid the Sciatic Nerve Superomedial Quadrant to avoid the Common Fibular Nerve You are doing clinical rotations when an 82 year old female patient comes into the emergency department complaining of severe right hip pain. You acquire the x-ray shown below. Due to the possibility of avascular necrosis, which of the following arteries are you most concerned about being damaged? Acetabular branch of obturator artery Lateral circumflex femoral Medial circumflex femoral Femoral artery Internal pudendal artery Which of the following is NOT a border of the femoral triangle? inguinal ligament Sartorius tensor fascia latae adductor longus none of the above While jogging down a poorly lit road, Ricky slipped on a wet spot and managed to severely tear his pectineus. Which actions will he now have difficulty performing? flexion and medial rotation of the thigh abduction and medial rotation of the leg adduction and flexion of the thigh abduction and extension of the leg abduction and extension of the thigh A patient comes into the clinic complaining of pain along the medial aspect of their calf, foot, and ankle. Upon examination of their posterior knee you notice a large pulsating mass and suspect an aneurysm of the popliteal artery. Which of the following nerves is mostly likely being affected by this condition? Common fibular nerve Sural nerve Saphenous nerve Superficial fibular nerve Tibial nerve After he fell off a roller coaster, Johnny broke every bone and tore nearly every nerve in his body. However, his femoral nerve remained unscathed and Johnny made a full recovery. Which muscle was still functional after the miraculous landing? Vastus medialis Piriformis Quadratus femoris Semitendinosus Obturator externus Which of the quadriceps muscles has a primary function other than extension at the knee joint? Vastus Lateralis Vastus Medialis Vastus Intermedius Articularis Genu Rectus Femoris Chloe suffers from chronic kidney infections usually brought about from UTIs. She usually gets Doribax, an IM-injected antibiotic, at the first sign of a UTI to prevent it from becoming a kidney infection. While at the doctor’s office, a new nurse is training and begins to prep the lower lateral quadrant of her left buttcheck when her trainer stops her. Why shouldn’t the shot be injected there? There isn’t enough subcutaneous fat in this region so it would cause unnecessary pain This region is highly vascular and would cause bleeding This drug should be given IV and not IM This region has large nerves passing through that could be punctured causing nerve damage There is too much subcutaneous fat in this area and it would not be well-absorbed. Which of the following is NOT a component of the Femoral Triangle? Sartorius Iliopsoas Inguinal Ligament Gracilis Adductor Longus Edna was carrying in her groceries when she slipped and fell on the ice hitting the posterolateral aspect of her hip and buttocks. She is unable to rotate her toes inward with her leg straight from a standing position. Which of the following muscles is likely injured? Tensor Fasciae Latae Gluteus maximus Piriformis Pectinius Obturator externus Which of the following is NOT a function of the Sartoris? Flexion at the hip Lateral Rotation of the Thigh Extension at the knee Medial Rotation of the Leg Flexion at the knee Vivian is an avid rock-climber. While rappelling down, her cable was too loose causing her to rappel down very quickly. On her rapid dissent, she was punctured in her right gluteal region with a very sharp stick which went into the thickest part of her right glute about two inches. While in the ER, she is asked to stand on her left leg and her right hip veers up. Which of the following nerves did Vivian injure? Sciatic Superior gluteal Nerve to quadratus femoris Nerve to obturator internus Inferior gluteal A patient comes into the ER and has reportedly injured his pudendal nerve. Your attending tells you that he is concerned for the injury but also other possible injuries in the roots in the Sacral Plexus. What roots might be of concern? L5-S3 L4-S4 L4-S5 L2-S2 S1-S4 Respectively, which of the following muscle-nerve pairs is INCORRECT? Gluteus Maximus, Inferior Gluteal Nerve Gluteus Medius, Superior Gluteal Nerve Gluteus Minimus, Superior Gluteal Nerve Inferior Gemelli, Nerve to Obturator internus Superior Gemelli, Nerve to Obturator internus Which of the following muscles makes up a part of the floor for the popliteal fossa? Semitendinosus Biceps Femoris Plantaris Gastrocnemius Soleus A blockage is discovered in the popliteal artery just after it has passed through the adductor hiatus. Which of the following blood vessels will receive blood and then be able to bypass the blockage to allow blood flow inferior to the knee? Superior medial genicular artery Middle genicular artery Inferior lateral genicular artery Anterior tibial recurrent artery Descending genicular artery Which of the following nerves is sensory only? Sciatic Common Fibular Tibial Sural All of the above are mixed (sensory and motor) nerves A soccer player comes into the ED with pain in her posterior thigh after injuring herself in a game earlier that night. When looking at the patients MRI T2 scan you notice a large white area where she is feeling pain. What does the large white area represent? Hematoma Edema Muscle Strain Ischial tuberosity avulsion Tumor Time is Up!
