Eighty-five first-year medical and surgical residents at the University of Pennsylvania School of Medicine took a 25-question test; 82% failed to get a passing score.
We've received many inquiries about the study, including quite a few requests to see the questions.
Here they are. The answers appear at the bottom of the page. Basic competency is judged to be a score of 73%.
Basic-Competency Examination in Musculoskeletal Medicine*
Question- What common problem must all newborns be examined for?
- What is a compartment syndrome?
- Acute septic arthritis of the knee may be differentiated from inflammatory arthritis by which laboratory test?
- A patient dislocates his knee in a car accident. What structure(s) is/are at risk for injury and therefore must be evaluated?
- A patient punches his companion in the face and sustains a fracture of the 5th metacarpal and a 3mm break in the skin over the fracture. What is the correct treatment and why?
- A patient comes to the office complaining of low back pain that wakes him up from sleep. What two diagnoses are you concerned about?
- How is compartment syndrome treated?
- A patient lands on his hand. It is tender to palpation in the "snuff box" (space between the thumb extensor and abductor tendons). Initial radiographs do not show a fracture. What diagnosis must be considered?
- A 25-year-old male is involved in a motor-vehicle accident. His left limb is in a position of flexion at the knee and hip, with internal rotation and adduction of the hip. What is the most likely diagnosis?
- What nerve is compressed in carpal tunnel syndrome?
- A patient has a disc herniation pressing on the 5th lumbar nerve root. How is motor function of the 5th lumbar nerve root. How is motor function of the 5th lumbar nerve root tested?
- How is motor function of the median nerve tested in the hand?
- A 12-year-old boy severely twists his ankle. Radiographs show only soft-tissue swelling. He is tender at the distal aspect of the fibula. What are two possible diagnoses?
- A patient presents with new onset low back pain. Under what conditions are plain radiographs indicated? Please name five (example: history of trauma).
- A patient has a displaced fracture near the fibular neck. What structure is at risk for injury?
- A 20-year-old injured his knee playing football. You see him on the same day; he has a knee effusion. An aspiration shows frank blood. What are the three most common diagnoses?
- What are the five most common sources of cancer metastatic to bone?
- Name two differences between rheumatoid arthritis and osteoarthrosis.
- Which malignancy may be present in bone yet typically is not detected with a bone scan?
- What is the function of the normal anterior cruciate ligament at the knee?
- What is the difference between osteoporosis and osteomalacia?
- In elderly patients, displaced fractures of the femoral neck are typically treated with joint replacement, whereas fractures near the trochanter are treated with plates and screws. Why?
- What muscle(s) is/are involved in lateral epicondylitis (tennis elbow)?
- Rupture of the biceps at the elbow results in weakness of both elbow flexion and _______________?
- What muscle(s) control(s) external rotation of the humerus with the arm at the side?
