Assessment of BFX cup version in a three-dimensional model simulating the ventrodorsal radiographic view

Abstract

Objective: To measure truncated face and open face versions of the biological fixation (BFX) cup in a three-dimensional (3D) model simulating the ventrodorsal radiographic projection with different cup and pelvis positions. Study design: Computer simulation. Methods: Simulated ventrodorsal views were generated in silico using 3D models of a BFX cup and a medium-sized canine pelvis. Truncated face and open face versions of the BFX cup were defined and measured with various angles of cup version, cup inclination, and pelvic extension. Results: Truncated face version was different from and underestimated open face version by 12° to 22° (p
