Your patient’s x-ray shows a “Terry Thomas/David Letterman” sign. This finding suggests injury to which structure?

Which structure(s) would have a tensile force applied with hyperflexion of the knee?

Since ATP regeneration occurs through oxidative phosphorylation, we are able to calculate ATP usage during exercise by tracking the volume of oxygen flow in a test subject, and calculating the amount of oxygen used. This method of indirectly measuring ATP usage during exercise requires use to know the ratio of high energy phosphates (ATP) generated per unit of oxygen (O2).

What is the typical production ratio of high energy phosphates (ATP) per unit of oxygen (O2)?

What are the boundaries that define the axilla?

A patient in your clinic complains of knee pain, and demonstrates a positive lever sign. The positive lever sign suggests what structure is injured?

A patient comes to you complaining of hip pain. After preforming your exam, you suspect she has avulsed her sartorius from its origin. You order some diagnostic imaging to confirm your diagnosis.

Based on these suspicions, you would expect imaging to show injury to which bony prominence?

which test would be used to determine an anterior cruciate ligament (ACL) rupture?

A patient comes to you complaining of knee pain, after playing soccer two days ago. He states that he felt a “pop” and that he is reluctant to bear weight on his injured knee.

Which of the following findings would make you think he injured his anterior cruciate ligament (ACL)?

Compartment syndrome is a condition in which pressures around skeletal muscles rise to a level that cuts off blood flow and compresses nerves around the muscles. A 66-year old woman is involved in a high-speed motor vehicle collision and presents with a left femoral shaft fracture. After fixing her bone with an intramedullary rod, the patient is taken to the recovery room. Upon waking she complains of intense pain in her left thigh as well as sensory deficits in the anterior portion of the same thigh. You diagnose her with compartment syndrome and suspect that a nerve is being compromised.

If left untreated, what action do you expect the patient will not be able to perform?

While testing a patient with shoulder pain, you find that he has a positive anterior slide and positive crank tests. Based on these results, what pathology is the most likely cause of his symptoms?
