Abstract
The present study was conducted on 12 clinical cases of dogs of either sex with distal diaphyseal long bone fractures. The animals were randomly divided into two groups having equal numbers viz. Group A in which the fracture was stabilized with End threaded positive profile intramedullary pins and Group B by Titanium elastic nails. Diagnosis of the distal diaphyseal fracture done by preoperative clinical evaluation and radiography. Various parameters like clinic-physiological parameters like rectal temperature, heart rate, respiration rate, inflammation, pain score, lameness and weight bearing score, Haematobiochemical parameters like Hb, TEC, TLC,DLC & ALP were recorded in all the animals at various time interval. Clinico-physiological parameters did not show any significant difference between the both groups and were fluctuating within normal physiological range. Intra operative observation like duration of surgery, radiation exposure time, extent of manipulation and soft tissue damage, degree of technical difficulties, status of fracture reduction and fracture fixation was also recorded. The mean duration of surgery and intraoperative radiation exposure time significantly less in Group A compare to Group B. Lameness score was significantly less in group B compare to group A. The weight bearing score was significantly more in Group B as compare to Group A. Post-operative radiograph revealed intact implants with evidence of significant bridging callus and better radiographic healing grade in Group B as compare to Group A. Functional outcome score was significantly more in Group B as compare to Group A. The post-operative complication comprised of loosening and distal migration of pin in one case of Group A. The haematobiochemical parameters were within the physiological range and change in the mean values between the groups were statistically non-significant. For the physiological and anatomical repair of the fracture site, the titanium elastic nailing was found to be superior method than End threaded positive profile intramedullary pinning.Titanium elastic nailing resulted in early weight bearing and limb use along with better ability to withstand the stresses of weight bearing.
