Q
  1. A 33-year-old man injures his right wrist and left leg in a motorcycle collision. He has a closed left midshaft tibia fracture and a closed comminuted right intra-articular distal radius fracture. Prior to treatment, he reports mild paresthesias in his right hand but can identify light touch on all digits. The surgeon performs closed reduction and splinting of both injuries, and the patient reports resolution of the median nerve paresthesias. Eight hours later, the surgeon is called to evaluate the patient because of increasing pain in his right arm. He appears agitated and uncomfortable, with a heart rate of 120 and blood pressure of 135/90 mm Hg. The surgeon opens his splint, and his right forearm compartments are soft. His fingers are pink and well perfused with brisk capillary refill. He cannot identify light touch to his thumb, index, or long finger, but can identify light touch to his small finger. He can actively flex and extend the digits through a small arc of motion with pain and has discomfort with passive stretch. What is the best next step?
  2. Measure forearm compartment pressures
  3. Obtain a stat complete blood count (CBC) and electrocardiogram (EKG)

Q
  1. A 64-year-old man is seen in the emergency department after tripping over a rug. An examination reveals a midshaft femoral fracture through a lytic lesion. Laboratory studies including a complete blood count, metabolic panel to assess renal and hepatic function, urinalysis, prostate specific antigen, and protein electrophoresis are conducted; all values are within defined limits. What is the best next step?
  2. MRI of the lesion; CT scans of the chest, abdomen, and pelvis; and an open biopsy for later planning
  3. MRI of the lesion; CT scans of the chest, abdomen, and pelvis; and biopsy of the lesion at the time of fixation
  4. MRI of the lesion; CT scan and positron emission tomography (PET)-CT scans of the chest, abdomen, and pelvis; biopsy of the lesion at the time of surgery
  5. CT scans of the lesion, chest, abdomen, and pelvis and a closed biopsy with an oncology review for method of fixation
  6. CT scan of the lesion; CT scan and PET-CT scans of the chest, abdomen, and pelvis; biopsy of the lesion at the time of surgery
