Abstract
ABSTRACT:
The present study was conducted on “Designing and evaluation of artificial
limb prostheses in dogs”. Among a total of 1001 canine cases referred to Department
of Veterinary Surgery and Radiology, College of Veterinary Science, Tirupati from
January to December 2017, 202 cases were related to orthopaedic ailments wherein,
14 cases were not suitable for surgical management and required amputation as a
salvage procedure. Based on inclusion and exclusion criteria six animals were
utilized for the study. Detailed clinical, orthopaedic and neurological examinations
were carried out on the cases included in the study. The animals had crush injuries
with loss of muscle, bone, cutaneous tissue, open wound and neoplasia. In all the
animals, amputation or disarticulation was performed as per the case. Biochemical
parameters like calcium, phosphorus and alkaline phosphatase were estimated at 0, 7,
14 and 21 days post surgery. The calcium and phosphorus values showed nonsignificant
changes whereas, alkaline phosphatase levels showed significant change in
the present study. Skiagrams taken provided information about types of fractures,
bones involved and level to which amputation or disarticulation to be performed.
After amputation or disarticulation measurements were taken on contralateral limb to
prepare prosthetic limb. Various steps like measurement recording, contouring of the
angulation, identification of pressure points, negative casting, filling the cast,
moulding with HDPE pipe, padding with ethylene foam and preparation of edges with
Velcro and belt were carried out. The prepared prosthetic limbs were applied to the
animals after complete healing. Outcome of the prosthetic limb usage was
characterized by its acceptance, functioning, loosening or break of the material. The
owners were advised to practice the adaptation of the prosthetic limb to the animal at
regular interval for better outcome
