DR MSK Flashcards
with a displaced transverse humerus fracture which nerve is most susceptible to injury?
axillary nerve
what clinical sign if axillary nerve is damaged?
sensory loss over regimental badge region
weakened abduction due to loss of innervation to deltoid and teres minor
how does a posterior shoulder dislocation appear on x ray?
‘lightbulb’ sign
what is colles fracture? what clinical sign is seen?
transverse fracture of distal radius
‘dinner fork’ deformity > dorsal angulation of distal fragment of fracture
what is a risk factor for colles fracture?
osteoarthritis
how would the leg appear with a posterior hip dislocation?
shortened and internally rotated
which nerve greatest risk of damage from posterior hip dislocation?
sciatic
how is the blood supply affected with an extra capsular NOF fracture?
blood supply from circumflex, femoral and retinacular artery preserved !!! as its extracapsular
which nerves runs in close proximity to medial malleolus?
tibial
borders of the adductor canal?
roof/anterior boundary= sartorius
lateral= vastus medialis
posterior= adductor longus + magnus
borders of the axillary region
medial= serratus anterior lateral= humerus anterior= pec major and minor posterior= latissimus dorsi/ subscapularis
