ANAT LE
The main blood supply for the femoral head in adults.
medial circumflex femoral artery
Osteoarthritic patients might develop Heberden nodes in this joint.
DIP joint
It's the most common benign bone tumor that's typical to adolescents.
osteochondroma
Emo kids might have this nerve impingement condition, causing a "burning" sensation to the lateral thigh.
meralgia paresthetica
A disorder caused by CTG repeat expansion with delayed muscle relaxation.
This muscle runs from the ASIS to the pes anserinus.
sartorius muscle
Treatment of rheumatoid arthritis with this class of medication puts patients at risk for infection reactivation (TB, Hep B).
TNF inhibitors
Tumors in Ewing sarcoma have this appearance on imaging.
onion skin
A proximal injury to this nerve will leave the patient feeling "holy" when trying to make a fist.
median nerve
This somewhat outdated test causes brief, rapid improvement in symptoms for myasthenia gravis patients.
edrophonium test
The femoral artery and femoral vein pass through this arch-like structure.
adductor hiatus
In gout patients, it's a negative finding in monosodium urate crystals under parallel light.
birefringence
Sickle cell disease patients are at highest risk for osteomyelitis from this species.
Salmonella
Compression of the axillary artery won't cut off blood supply to the arm or shoulder completely thanks to this network.
scapular anastomosis
Muscle weakness improving with activity would make this diagnosis more likely.
LEMS
The superior gluteal nerve innervates muscles that mainly contribute to this action at a certain joint.
hip abduction
The expected lab abnormality in Paget's disease.
increased ALP
The femoral head can show this celestial sign when it loses blood flow.
crescent sign
Resting medial rotation of the shoulder, extension of the elbow, and flexion of the wrist with muscle atrophy and sensation deficit.
Erb's palsy ("waiter's tip")
A muscular disorder associated with thymic hyperplasia/thymoma.
myasthenia gravis
The quadratus femoris muscle shares its innervation with this muscle.
inferior gemellus
This type of tissue forms during the soft callus stage of bone healing.
granulation tissue
These are two pathologic findings in osteomyelitis characterized by 1) necrotic bone fragments, and 2) new bone formation around them.
sequestrum + involucrum
Abnormal abduction, extension, and external rotation at the hip with extreme pain. Be specific!
anterior hip dislocation
A patient with perimysial inflammation and perifasicular muscle fiber atrophy might have this facial sign.
heliotrope rash
