Tibia Flashcards
3 common sites of tibial stress fractures
TOP: caudolateral cortex proximally
MIDDLE: mid-shaft caudolateral cortex
BOTTOM: caudomedially or laterally distally
Can be bilateral
Scintigraphy is the dx test of choice <50% will have radiographic evidence even if repeated in 2 weeks
Most common tibial fracture configuration in foals? How is this thought to occur?
Where is the implant placed for repair of this fracture?
SHII fracture of the proximal tibial physis. Metaphyseal fragment located on the LATERAL side
Occurs dt trauma eg foal attempts to stand with upper limb trapped, mare stands on distal limb or direct trauma to physis.
Trauma to the lateral aspect of the physis exherts bending force - fracture line opens on medial side → tracks laterally then deviates through the metaphysis to create a lateral metaphyseal fragment
Implant (LCP pref) placed MEDIALLY on the proximal tibia
