| Summary: Fracture healing outcomes using an Aircast pneumatic (pressurized) brace were compared to healing with a fiberglass cast. The authors found that "a pressurized brace yields a stronger healed fracture than does a traditional cast… intermittent elevation in venous pressure may occur as the dog bears weight and therefore may increase capillary filtration and perfusion of osteoblasts at the fracture site." By measuring compartment pressure with the application of the pressurized brace, they found that the "pressure [was] below the levels that would induce any cellular metabolic derangement." |
