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 fibreglass (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 osteotomized 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 greater with cranial FG splints than with cranial TP splints (p 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 with TP and may therefore have slight superiority for this application.
