| 【Abstract】 Objectives: To evaluate the fusion effect and stability of self-designed upper thoracic vertebra instrument in goat. Methods: 16 adult Boer goats were divided into four groups randomly: group A underwent self-designed upper thoracic vertebra anterior titanium plate, group B with non-shaped Orion plate, group C with shaped Orion plate, and group D included normal thoracic vertebra specimens. The goats of group A, B and C underwent T3 corpectomy and bone graft, while group D underwent T3 corpectomy alone. The fusion effects and complications were observed by radiological and histological examinations 3 months later after the surgery. Results: One goat in group D died of anesthesia accident, while the others survived with no instrument-related complication. Imaging fusions were as follows: grade Ⅰ in 4 goats of group A, 1 of group B, 2 of group C; grade Ⅱ in 3 goats of group B, 2 of group C and D; grade Ⅲ in 1 of group D. Histological fusions were as follows: grade Ⅰ in 3 of group A, 2 of group B, 1 of group C; grade Ⅱ in 1 of group A, 2 of group B and C; grade Ⅲ in 1 of group C, 2 of group D; grade Ⅳ in 1 of group D. Group A was better than the other 3 groups(P＜0.05), and group B and C were better than D(P＜0.05). No significant difference between B and C was found(P＞0.05). Conclusions: The anterior titanium plate after upper thoracic vertebra corpectomy proves to have satisfactory reliability and better fusion effect in goat. |
