Abstract:
Fractures, joint luxations and severe injuries of the equine distal limb are indications for the use of fibreglass casts in horses. Pressure ulcers are a frequent complication of limb immobilization, may prolong healing and worsen the prognosis. In this in vitro study two different immobilization techniques were used to compare skin pressures on equine distal forelimbs during simulated walking load. Ten pairs of equine cadaveric distal forelimbs were used. Pressure detecting films were placed on common pressure ulcer sites and the limbs were immobilized either with PFI or FCI. Limbs were then axially loaded 100times with 3000N in a tensile testing machine. Perfect conformation to the limb was achieved with PFI. Pressure at proximal sesamoid bones and dorsal fetlock were significantly higher with PFI. High pressures are exerted on the limb with PFI, so strong confirmation and stabilization to the limb is expected. However the incidence to create pressure ulcers may be enhanced too. In both immobilization techniques high pressures at the proximal sesamoid bones and proximal dorsal metacarpus substantiate the risk of the development of pressure ulcers at these sites. Further studies are required to optimize and establish the PFI technique for routine use in equine practice.
