Evaluation of fixation devices for resistance of bending and rotations in supracondylar femoral fracture fixation in dogs

Transverse supracondylar femoral fracture was done in 20 dogs, divided equa lly in groups, A, B, C and D. Fixation was done using cross intramedullary pins (group A), single pin passed through the intercondyloid fossa (group B ), standard stainless steel plate (group C) and properly contoured horn pla te (group D). Intramedullary pins (groups A and B) could resist bending for ces more effectively compared to plates (groups C and D) and maximum bendin g was recorded in stainless steel plated animals. Rotation of the distal fr agment was more with single pin fixation (group B): than any other group. H orn plating effectively counteracted both rotational and bending forces and thus provided rigid fracture fixation.
