Abstract
The present study was conducted on 12 backyard poultry birds taken as
experimental model for fracture repair. Tibio-tarsal bone fracture was created under
xylazine-ketamine anaesthesia by obtaining permission from Institutional Animal Ethics
Committee (IAEC). Birds were divided into two groups consisting of six birds in each
group. In group I, the fractures were stabilized with non-locking reconstruction plate and
in group II fractures were repaired with locking reconstruction plate. Xylazine @ 3mg/kg
BW and ketamine @ 30mg/kg BW proved to be a good general anaesthetic combination
for fracture repair in poultry. In group I, birds showed mild to moderate weight bearing
from day 15 onwards and good to very good weight bearing on 30th and 45th post-operative
days. However, in group II, the birds showed mild to moderate weight bearing from 7
th
post-operative day itself and good to very good weight bearing from 30th and 45th
post-operative days. On an average the weight bearing in birds fixed with both the plates
were slightly similar from 45
th and 60th post-operative day. Both the types of
reconstruction plates are not available commercially, have to be fabricated and are
successful for fracture repair in birds. The fracture healed with minimal callus resembling
primary union. The remodelling is quite early especially when screws were locked. In
group I, callus formation was more appreciable at the fracture site as the screws were not
locked for the reconstruction plate. In group II, the callus was very minimal for the
reconstruction plate. The bio-chemical analysis showed non significant rise in serum
calcium, serum inorganic phosphorous and serum alkaline phosphatase on 15th and 30th
post-operative days and were within normal limits. The levels returned to base values by
45th and 60th post-operative day
