The management of comminuted tibial fractures is a challenging problem in small animal orthopedics. External skeletal fixators with Maynard clamps and Schanz pins are commonly used for the osteosynthesis of such fractures. The aim of this study was to perform a clinical assessment of Schanz pins with type II frame external fixators in the treatment of comminuted tibial fractures, and the possibility of pin changing when osteolysis and pins loosening appear using Maynard clamps. Schanz pins and external fixators were applied in five dogs. The healing of the treated tibia bones was noted in all cases. Radiological signs of osteolysis, pin loosening and pin tract discharge were observed in two dogs. The results obtained indicate that Schanz pins with type II frame external fixators are reliable and easily manageable. It was also ascertained that Maynard clamps are especially useful for quick pin changing.
