unilateral, injury
A patient presents with ankle pain associated with climbing stairs. After finding the ankle to be swollen and stiff, you diagnose the patient with osteoarthritis. For many patients with this condition, a non-pharmacological, non-surgical treatment results in symptom relief. What is that “treatment”?
weight loss
A 34 year-old male presents with posterior ankle pain. He states that the pain onset acutely when he attempted to steal a base in a softball game. The patient describes feeling as if he’d been “shot in the back of the leg”. On exam, you find the posterior ankle swollen and tender. The patient is unable to plantar flex the ankle.

Plantar fasciitis
A patient presents with bilateral femur fractures, a posterior hip dislocation, and a scaphoid fracture that resulted from an automobile crash. What is your first priority in managing this patient?
Airway, Breathing, Circulation
A patient presents with right knee pain and associated effusion. You perform a joint aspiration and find the fluid’s cellularity to be greater than 100,000. Which common knee pain treatment is absolutely contraindicated in this case?
Steroid injection
A patient presents with shoulder pain that radiates down the upper arm unilaterally. The patient states that the pain began after a weekend that he spent painting his living room. Suspecting shoulder impingement syndrome, which two specific tests do you perform?

Do you use cocaine? Wait…no, not that.
Bowel/bladder dysfunction (incontinence, urinary retention)
A 20 year-old male presents with lower back pain and stiffness that is worse in the morning and somewhat relieved by activity.

Ankylosing Spondylitis
A 19 year-old male presents with joint pain and stiffness in the knees and ankles. He also endorses pain with urination and penile discharge. On exam, you note uveitis. WBC and ESR are elevated. What is the most likely diagnosis, and what is its most common etiology?
Reiter Syndrome
Chlamydia Trachomatis
A patient presents with swelling and tenderness of the DIP joints. On exam, you find the DIP joints to be red and warm, and note that there is pitting and yellowing of the fingernails as well. X-rays of the hand show a “pencil in cup” deformity. What is the most likely diagnosis?
Psoriatic arthritis
A patient presents with swelling and tenderness of the DIP joints. On exam, you find the DIP joints to be red and warm, and note that there is pitting and yellowing of the fingernails as well. X-rays of the hand show a “pencil in cup” deformity. To support a diagnosis of psoriatic arthritis, which serum factor should be negative?
Rheumatoid factor
A rheumatology PA is examining a patient with a history of SLE who has developed some chest pain that is relieved by leaning forward. The PA goes to the store and buys a stethoscope, then calls a friend from PA school who reminds her how to use it. The PA notices a pericardial friction rub and orders an EKG that shows diffuse, concave ST-segment elevations. Which potential complication of SLE is most likely?
Pericarditis
The vast majority of patients with lupus will have a ______(positive/negative) ANA test. Most people with a positive ANA test ______ (do/don’t) have lupus. In diagnosing lupus, ANA testing is highly ______ (sensitive/specific), but lacks ______ (sensitivity/specificity).
positive, don’t, sensitive, specificity
48 hours after undergoing ORIF for a tibial fracture, a 25 year-old male patient develops intense leg pain that is refractory to morphine and hydromorphone. He has significant pain with passive ROM. What is the most likely diagnosis, and what is the treatment of choice?
Compartment syndrome, fasciotomy
A patient presents with anterior shoulder pain within the intertuberous groove that is aggravated by resisted supination. What is the most likely diagnosis?
Biceps tendonitis
An abnormal Cobb angle is indicative of what disorder?
Scoliosis
A patient presents with an inferiorly displaced patella. Which tendon is most likely damaged?
Quadriceps tendon
Compared to benign lesions, malignant bone lesions are more likely to be ______ (lytic/blastic), are ______ (more/less) likely to be painful, and have a ______ (higher/lower) likelihood of invading adjacent tissue.
lytic, more, higher
A patient presents with a dislocated knee. You reduce the dislocation and then consider an angiogram to assess for vascular damage. Which vessel are you most concerned about, given the injury?
Popliteal artery
A patient who is recovering from a generalized tonic-clonic seizure complains of shoulder pain. Which radiographic view will be most useful in assessing this patient’s condition?
Axillary lateral view
A patient suffers radial nerve injury in an automobile crash. You have a high index of suspicion for a fracture of which bone, since it’s the most common site of median nerve injury?
Humerus
A 65 year-old female presents with a 1-month history of shoulder and hip pain. She also reports a 10-pound unintentional weight loss and low-grade fever during that time. On exam, strength is 5/5 throughout, but ROM is limited in the shoulders. Which laboratory study would be of most value in confirming your clinical suspicion?
ESR
A 65 year-old female presents with a 1-month history of shoulder and hip pain. She also reports a 10-pound unintentional weight loss and low-grade fever during that time. On exam, strength is 5/5 throughout, but ROM is limited in the shoulders. You suspect that the pt has polymyalgia rheumatica. What is the most serious potential complication of this disease, and what is the gold standard for its diagnosis?
Temporal arteritis, temporal artery biopsy
