Background:
Minimally invasive plate osteosynthesis (MIPO) is an emerging fracture management modality in small animal orthopedics. Although cranial plate application has been consistently advocated when performing radial MIPO, medial plating affords several purported advantages including improved screw purchase through the wider medial-to-lateral dimension of the radius, the potential to use smaller plates allowing more screws per unit length, and avoidance of extensor tendons which can complicate cranial plate placement in distal diaphyseal or metaphyseal fractures.
Aim:
To compare cranial verses medial MIPO applications for the stabilization of diaphyseal radius and ulna fractures in dog cadavers.
Methods:
Simulated bilateral antebrachial fractures were stabilized with cranial MIPO on one forelimb and medial MIPO on the contralateral limb, facilitated by a 2-ring circular fixator construct. Procedure times and ease, number of fluoroscopic images obtained, and post-procedural frontal and sagittal alignment and radial length, were compared between plating groups. The ease of construct placement, fracture reduction, radial approach, and plate application, were subjectively scored 1-5 for each procedure. Paired t tests were performed to identify significant differences (P
