Abstract

Bone scintigraphy with $^{99m}Tc-methylene$ diphosphonate(MDP) performed for 20 weeks per two weeks interval respectively after fracture in seven(male 3 heads, female 4 heads) canine radius were analysed. All of bone scans performed 2 weeks to 20 weeks after fracture showed increase in generalized tracer uptake and showed localized increase in tracer uptake at the fracture site. Bone scans and ratio performed 6 weeks after fracture showed the most outstanding increase in generalized and localized tracer uptake. New bone formation had been observed from 2 weeks and they were incorporated completely on 18 weeks, they showed most activity during 6-10 weeks after fracture. It was recognized that the bone scan with $^{99m}Tc-methylene$ was quite sensitivity but low specificity on the fracture healing in canine radius.
