Abstract
Maiti, S.K., Kumar, N., Singh, G.R. and Hoque, M. 2003. Effect of ultrasound therapy on fracture healing in rabbits. J. Appl. Anim. Res., 24: 25–32.
The effect of two different doses of ultrasound on fracture healing was studied in 12 adult New Zealand white rabbits divided equally in 3 groups (A, B and C). In all animals, midshaft transverse fracture of both the ulnae was created under thiopental (2.5%) anaesthesia. Ultrasound therapy at the rate of pulsed (1:1) 1W/cm2 and continuous 3W/cm2 were given on every alternative day (10 treatments), starting from day 4 post-fracture in groups A and C, respectively. Group B with no therapy served as control. Resolution of inflammatory swelling and pain was earlier in group A followed by groups B and C. Rectal temperature, Hb, TLC and DLC did not vary significantly at various stages of observations in all the three groups. In group A, periosteal proliferation started as early as on day 10 post-operatively and complete obliteration of fracture gap by bridging callus was observed on day 30. Remodeling of bridging callus and well-developed periosteal continuity were evident oil day 40 PO. Group C revealed pathological fracture and delayed and mal-union. Whereas, in control group B, fracture healing was comparatively slow, delayed and the defect site was well visible till day 40 PO. Histopathological observations further confirmed the radiological and clinical findings. No physiological side effects and other complications were observed in any group.
