|dc.description.abstract||Objectives: Various materials are used to construct splints for mid-diaphyseal tibial fracture stabilization. The objective of this study was to compare construct stiffness and inter-fragmentary (bone) motion when fiberglass (FG) or thermoplastic (TP) splints are applied to either the lateral or cranial aspect of the tibia in a mid-diaphyseal fracture model. Methods: A coaptation bandage was applied to eight cadaveric canine pelvic limbs, with a custom formed splint made of either FG or TP material applied to either the lateral or cranial aspect of the tibia. Four-point bending tests were performed to evaluate construct stiffness and inter-fragmentary motion in both frontal and sagittal planes. Results: For a given material, FG or TP, construct stiffness was not affected by splint location. Construct stiffness was significantly higher with cranial FG splints than with cranial TP splints (p<0.05) but this difference was less evident when comparing splints applied laterally (P=0.15). Inter-fragmentary motions in the sagittal and frontal planes were similar across splint types for cranial splints, but for lateral splints there was a 64% reduction in frontal plane motion when FG was used as the splint material (p=0.03). Clinical Significance: FG produces a stiffer construct but the difference is not reflected in a reduction in inter-fragmentary motion. For lateral splints, FG splints are associated with reduced inter-fragmentary motion as compared to TP and may therefore have slight superiority for this application.|
