Metatarsal Fractures Flashcards
Order of frequency for metatarsal fractures
5 - 3 - 2 - 1 - 4
Usually confirms the diagnosis and the sagittal plane is the most important
Radiographs
Usually for diagnosing metatarsal base fractures and intra-articular fractures
CT Scan
MOI of metatarsal head fractures
Direct trauma or Impaction
Vassal Principle
Fix the main fracture and the other fractures come together b/c they all share a common soft tissue structure
Typical MOI of metatarsal shaft fractures
Direct Trauma
Blunt force
Torsional injuries
Metatarsal base fractures often need what imaging?
CT
X-ray, too
Metatarsal base fractures are often associated with what?
Tarsometatarsal fracture-dislocation
If unable to treat within first few hours or if soft tissue envelope compromised then what how main days or until what?
7 days or swelling reduces

Type 1 Stewart
Metaphyseal-Diaphyseal junction
-Jones fracture
Type 2 Stewart
Intra-articular tuberosity without comminution
Type 3 Stewart
Extra-articular tuberosity fracture
Type 4 Stewart
Intra-articular, comminuted tuberosity
Type 5 Stewart
Fracture of the epiphysis
Factors influencing Jones fracture outcome (4)
Vascular supply
Mechanical Forces
Treatment inconsistencies
Population involved
Torg type 1 treatment
Same as Jones
Torg type 2 treatment
Inlay bone graft
IM screw
Torg type 3 treatment
Inlay bone graft
