OBJECTIVE: The goal of this study was to evaluate the difference in weight bearing in a toes-in splint versus a toes-out forelimb splint and to determine the difference in sub-bandage pressures between the groups. We hypothesized that (1) weight bearing would not be different between the 2 splints and that (2) sub-bandage pressures would be distributed higher on the distal digits in the toes-out splint and pressures would be more evenly distributed across the paw in the toes-in splint.
METHODS: In this controlled crossover trial, a random forelimb of 10 healthy dogs was bandaged with a splint that left the digits exposed and again with a splint that encompassed the digits. The ground reaction forces and the difference in sub-bandage pressures between 2 sensor sections were compared between the toes-in and toes-out bandages.
RESULTS: The mean (SD) of peak vertical force was 26.76% (11.86%) for the toes-in bandage and 49.85% (9.21%) for the toes-out bandage. The mean (SD) sub-bandage pressure differences between sections were -121.28 (138.28) mm Hg and 130.32 (116.40) for toes-in and toes-out bandages, respectively (P = .001). This remained significant even after weight bearing was removed as a factor (P < .001).
CONCLUSIONS: Leaving the distal aspect of digits 3 and 4 exposed by a splint results in better weight bearing, but also creates a sub-bandage pressure increase on the toes relative to the rest of the paw.
CLINICAL RELEVANCE: These results suggest that splint placement should be adjusted based on the needs of each patient.
