Abstract
Distal limb reconstruction is complicated by the paucity of local tissues and
the frequent association of orthopedic injury with cutaneous loss. Though,
second-intention healing or skin stretching techniques are used for wounds
involving less than a 30% circumference of the limb, however, skin grafts are
recommended for reconstruction of larger superficial wounds. The present study
was designed to clinically evaluate the viability of split thickness autogenous
skin transplantation (STAST) in dogs. Standardized surgical defects of variable
size i.e. 3×3, 4×4 and 5×5 sq cm were made on the left middle radial area
(forearm) of 15 mongrel dogs assigned to Group A, B and C, respectively having 5
dogs each. Split thickness autogenous skin grafts were harvested from mid thorax
and placed in these defects through several simple interrupted sutures. Results
indicated a success rate of 80% with no clinical difference in the survival rate
of three different sizes of grafts used. Hence, STAST can successfully be used
for canine distal limb reconstruction.
