Dyaphiseal fracture of the crus – open and closed. Flashcards
what are the open classification of tibial fractures ?
GUSTILO ANDERSON CLASSFICATION
grade 1 - clean open wound which is less than 1 cm
simple fracture pattern
grade 2 = 1-10cm
without significant soft tissue crushing
simple fracture pattern
grade 3 - more than 10 cm
and there is contamination
with significant soft tissue injury
3a - there is adequate tissue for closure
3b - patient would need flap due to inadequate soft tissue coverage
Treat proximal 1/3 fxs with gastrocnemius rotation flap,
middle 1/3 fxs with soleus rotation flap,
distal 1/3 fxs with free flap
3c - has vascular injury requiring repair or amputation indicated by segmented or comminuted fracture type
segmental fractures are grade three even if the open fracture is 1cm
what is the indication for amputation in open tibial fractures ?
warm ischemia for more than 6 hours, absent plantar sensation , several ipsilateral foot trauma
before we do surgery for open tibial fractures what needs to e done ?
need to give antibiotic prophylactic and meticulous debriment
what is the classification of closed fracture of the tibia ?
ota classification
soft tissue injury classification
grade 0 - negligible soft tissue damage from indirect forces
grade 1 - superficial abrasion with simple fractures
grade 2 - deep abrasion with muscle and skin contusion
impending compartment syndrome
grade 3 - excessive skin contusion , destruction of muscle , acute compartment syndrome
rupture of major blood and vessels
what are the indication for closed reduction
closed reduction and cast immobilisation
less than 5 degree varus or valgus angulation
less than 10 degree anterior or posterioir angulation
more than 50 percent cortical contact
less than 10 degree rotational malalignmnet
place in a long leg cast and convert to functional brace at weeks
what are the operative ways ?
is not meeting the non operative criteria
most open fractures , segmental fractures , comminuted fractures
ipsilateral tibia fracture
open reduction and intramedullary nail fixation
reamed nail is superior in closed tibial fractures but not open tibial fractures
but reaming can cause disruption of endosteal blood supply , thermal necrosis , fat embolism and intramedullary infection
unreamed rods uses smaller nails but preserves ensoteal blood supply
open tibial fractures can lead to what sort of problems ?
osteomyelitis
nonunion
infected nonunion
what causes tibial fractures ?
high-energy collision
direct forces often result in wedge or short oblique fx comminution
fibula fx at same level
severe soft tissue injury
low energy
typically caused by a twisting force and result in an oblique or spiral fracture
what are the complication in tibial fractures
anterior knee pain with IM nailing occurs with patellar tendon splitting for operational purposes
malunion - valgus and procurvatum
compartment syndrome
