-what was the effect of the SIRIUS bone reduction handle system?
improved fracture gap
Nabholz, VCOT 2020
Safety and accuracy of minimally invasive long bone fracture repair using a 2.5mm interlocking nail: a cadaveric feline study
-which bone encountered no complications?
-which site encountered most complciations
-effect of fluoroscopy?
tibia no complications
distal humerus most complications (damaging neurovascular structures distal humerus)
fluoroscopy did not affect any outcome measures.
Miranda, JFMS 2020
Radiographic study of the development of the pelvis and hip and the femorotibial joints in domestic cats
-what was the first growth plate to close?
- which were the last to close and at what time (i.e. when is complete growth plate closure)
ischiopubic (2 months)
distal femur and proximal tibial last to close ( 18 months)

infection rate?
explant rate of infected cases?
any benefit of post op abx?
4.6%
39% explanted
no benefit of post op abx, but tose that had post op abx and got an infection developed oxacillin resistant bacterial infectiones
