Objective—To evaluate healing of pinch-grafted
wounds on the distal aspect of the limbs of ponies
bandaged with equine amnion or a standard nonadherent
wound dressing material.
Procedure—A 2.5 × 2.5-cm full-thickness section of
skin was removed from the dorsal aspect of each
limb at the midpoint of the metacarpus or metatarsus.
Six days later, wounds were grafted with partial-thickness
pinch grafts. Half the wounds were bandaged
with amnion, and the other half were bandaged with
a nonadherent dressing. Bandages were changed
every 3 days until wound healing was complete. At
each bandage change, numbers of grafts lost were
recorded, and wounds were measured.
Results—Percentage of grafts lost from wounds bandaged
with amnion was not significantly different
from percentage lost from wounds bandaged with
the nonadherent dressing. Median healing time for
wounds bandaged with amnion (30 days) was significantly
less than median healing time for wounds bandaged
with the nonadherent dressing (39 days). All
wounds were healed by day 45.
Conclusions and Clinical Relevance—Results suggest
that amnion can be used for bandaging pinchgrafted
wounds on the distal aspect of the limbs of
ponies. (Am J Vet Res 2000;61:326–329)
