A. legg calve perthes dz
B. osgood schlatter dz
C. osteomyelitis
D. recurrent sprain
E. septic arthritis
F. slipped capital femoral epiphysis
G. stress fracture
H. tibia vara
I. toxic synovitis
I was pretty sure that B was the right answer. It was wrong. I thought this was a classic OSD with an athletic teen story, but it's apparently not. Any thoughts?
65 y/o female came to ER 1 hour after she fell. she has right wrist pain, her last doctor's visit was 10 yrs ago, exam shows swelling/tenderness of the Rt. wrist. x-ray of the wrist shows no fracture, but subperiosteal bone resorption is noted in the distal phalanges. her serum Ca2+ is 12.4, serum creatinine is 1.2, which of the following serum conc is most likely to be decreased in this pt?
A. 1,25 dihydroxycholecalciferol
B. magnesium
C. parathyroid hormone
D. phosphorus
E. vitamin C
I chose C but still got it wrong. any idea? thanks!
