Fracture classifications Flashcards
(16 cards)
Type1: dislocation of hallux and sessamoids, sesamoid apparatus intact, closed reduction Is irreducible
Type 2:A: disruption of intersesamoid ligament, closed reduction possible
Type 2:B: transverse sesmoid fracture, closed reduction possible
Jahss-mpj dislocation
transverse fracture of 5th mt base at diaphyseal-metaphyseal junction
- poor vascularity=poor healing
- aka jones fracture
stewart type 1
intra-articular avulsion fracture of 5th mt base
stewart type 2
extra-articular true avulsion fracture of 5th mt base
stewart type 3
Intraarticular comminuted fracture of 5th mt base
stewart type 4
Extraarticular avulsion fracture at the apophysis of 5th mt base
(in patient with open growth plates)
stewart type 5
navicular avulsion fracture of the tuberosity by the TP tendon
watson-jones type 1
navicular dorsal lip fracture
-don’t confuse with os supranavicular
watson-jones type 2
fracture of the body of the navicular
watson-jones type 3
piece of the 2nd mt pulled off by lisfranc’s ligament (from 1st cuneiform to base of 2nd mt) makes a large gap
Fleck sign
- total incongruity in lisfran fracture
- homolateral or homomedial (all mt to lateral or medial direction)
Hardcastle Type A
- Partial incongruous lisfranc fracture
- less than all the mt are dislocated in the same direction
Hardcastle type B
- Divergent lisfranc fracture
- medial dislocation of first mt and partial/total lateral dislocation of mt 2-5
hardcastle type c
ecchymosis seen on plantar, medial, and lateral aspect of calcaneus
mondur’s sign
Angles a/w calcaneal fractures
boehler’s angle: measures sagittal plane relationshop between talus and calcaneus. normal is 25-40 and fracture will lower or reverse the angle
critical angle of gissane: normal is 130 and will dec with intraarticular stj calcaneal fracture
- Fracture of plantar calcaneal tuberosity
- due to aBduction/aDduction exerted when heel strikes ground in inversion (lateral tuberosity fx) or eversion (medial tuberosity fx)
Rowe Type 1A
