What is the most common torn rotator cuff muscle
Supraspinatus
A patient presents to the emergency department for a laceration on the lateral aspect of their posterior wrist. All movements at the wrist joint and all movements of the fingers are unaffected, and she states that she cannot feel the back of her hand. Which nerve was likely injured?
Superficial radial nerve
What two structures are at risk of being injured with a mid shaft humerus fracture?
Radial nerve and deep brachial artery
What muscles attach to the extensor expansion
Extensor digitorum, extensor digiti minimi, and extensor indicis
What three muscles comprise the borders of the anatomical snuff box
Abductor pollicis longus, extensor pollicis brevis, extensor pollicis longus
A 25-year-old medical student presents to the clinic after sustaining a fall while playing soccer. On physical examination, the patient has difficulty extending the leg at the knee and experiences weakness when attempting to flex the hip.
Injury to which muscle group is most likely responsible for these deficits, and what is the primary function of this group?
Anterior compartment of the thigh; extension of the knee and flexion of the hip
A 68-year-old woman presents to the emergency department with a painful bulge in her right groin that has worsened over the past two days. She reports nausea and vomiting but denies any prior similar episodes. On physical examination, a tender, firm mass is palpated inferior to the inguinal ligament and medial to the femoral pulse. Bowel sounds are absent over the mass.
Which of the following best describes the anatomical location of this hernia and its boundaries within the femoral triangle?
Within the femoral canal
The adductor canal is located deep to which muscle
Sartorius
True or false, tapping the patellar tendon stimulates the patellar reflex and tests the function of the femoral nerve and spinal cord segments L1-L4
False
A 45-year-old man presents to the clinic with difficulty walking and pain in his inner thigh after a pelvic fracture. On physical examination, he has weakness in thigh adduction but intact hip flexion and knee extension. Sensory testing reveals decreased sensation over the medial thigh.
Which nerve is most likely injured?
Obturator nerve
Which superficial vein is sometimes used as a point of entrance for cannulation to provide a patient with prolonged administration of drugs, blood, or electrolytes
Great saphenous vein
The iliotibial tract is a thickening of what tissue layer in the thigh region
Fascia lata (deep fascia)
A 24-year-old medical student is practicing intramuscular injection techniques under the supervision of a clinical instructor. The student is asked to demonstrate proper placement of an intragluteal injection. The student identifies the posterior superior iliac spine and the greater trochanter as landmarks and proceeds to divide the buttock into quadrants. The instructor stops the student just before administering the injection and asks them to explain why the chosen site minimizes complications.
Which of the following is the correct location for intragluteal injections, and why is it preferred?
Upper outer quadrant to avoid injury to the sciatic nerve
What 4 muscles originate from the ischial tuberosity
Semitendinosus, semimebranosus, long head of biceps femoris, adductor magnus
The tendon of which muscle joins those of gracilis and sartorius muscles to help form the pes anserinus along the proximal tibia
Semitendinosus
The sciatic nerves exit the greater sciatic foramen by passing immediately inferior to what muscle
Piriformis
What nerve innervates the gluteus maximus muscle
Inferior gluteal nerve
A 52-year-old man presents to the emergency department with severe pain and pallor in his right lower leg after a fall from a ladder. On examination, there are weak pulses in the foot and near the ankle on the affected side. His right knee is swollen and tender, and he is unable to fully extend it. Imaging reveals a posterior knee dislocation.
Which of the structures lies immediately posterior to the knee joint in the popliteal fossa and was likely injured?
Popliteal artery
A 32-year-old female runner presents to the clinic with pain and swelling in the anterior aspect of her lower leg. She reports that the discomfort started gradually after increasing her weekly running distance. On examination, she has tenderness over the anterior compartment of the leg, particularly around the upper shin. She also complains of weakness when attempting to dorsiflex her foot. Which of the following muscles is most likely weakened in this patient?
Tibialis anterior
Which of the following nerves is responsible for innervating the skin of the web between digits 1 and 2 on the foot?
Deep fibular
Which of the following muscles attaches to the medial cuneiform and first metatarsal?
Fibularis longus
Dorsalis pedis artery is a direct continuation of which of the following arteries?
Anterior tibial
A 25-year-old male presents to the clinic with complaints of calf pain and difficulty plantarflexing his foot. He reports that he has been running long distances for the past few months in preparation for a marathon. On physical examination, he is unable to stand on his tiptoes or push off the ground with his foot. His posterior leg is tender to palpation, and there is mild swelling over the mid-calf.
Based on the symptoms described, which tendon is most likely to be involved in this patient’s condition?
Calcaneal tendon
