4a. Feet Flashcards
what are march fractures
stress fracture of the 2nd or 3rd metatarsal
what are the 3 5th metatarsal # types
stress, jones, avulsion
where is the jones # located
transition between metaphysis and diaphysis
where is the stress # located
within the diaphysis
what does the apophysis fracture look like
vertical fracture of base of 5th metatarsal
runs parallel to bone
what are calcaneal fractures
impacted fractures and stress fractures
what is the boehlers angle in terms of where the 2 lines are
line drawn from highest part of the ant process of the calcaneum and the highest point of the posterior articular surface of this bone
line between highest point of posterior articular surface of the calcaneus and the most superior part of the calcaneal tubersocity
what is the normal angle for boehler angle
25-40 degrees
what are the 2 midjoint foot fractures
chopart and lisfranc
what is the chopart fracture in terms of where it is
through the calcaneocuboid and talonavicular joints
what is the lisfranc fracture in terms of where it is
through the tarsal metatarsal junction
what are the components of a lisfranc fracture
Subluxation of metatarsals and move to one side generally and rupture of lisfran ligament but there is a pothole that the metatarsal sits in so It cant move out without breaking so always a fracture
Subluxation rather than dislocation
what are the 2 types of lisfranc fractures
divergent and homolateral
what is a divergent lisfranc fracture
metatarsal 2-5 are subluxed laterally
what is a homolateral lisfranc fracture
all metatarsals are subluxed laterally
