Study of the Efficacy of Modified Bone Traction on the Treatment of Tibial Fracture in Rabbits
Objective:To investigate the efficacy of modified bone traction therapy on the reduction of oblique tibial frac-tures in rabbits,and to assess the feasibility of applying an alternative bone traction scheme in clinical practice for patients with oblique fractures.Methods:A total of 24 white rabbits with similar body size and weight were chosen to perform diag-onal tibial fracture modeling by osteotomy,and after successful modeling,they were randomly divided into the control group(12 cases)and the observation group(12 cases),in which the control group received traditional axial bone traction technology and the observation group received modified bone traction.They all sat in supine traction for 14 d,and the frac-ture reduction effect,injured limb circumference,and vascular endothelial growth factor(VEGF)and interleukin-6(IL-6)values in serum of the two groups of rabbits before and after traction were measured.Results:The reduction rate of the two groups:the reduction effective rate of the observation group was 83.33％and was higher than that of the control group of 75.00％(P＜0.05).The circumference of injured limbs on the 1st,3rd,5th,7th and 14th day after traction in the two groups:the circumference of injured limbs in the observation group were 14.38,12.95,11.49,9.59,9.26 cm,respective-ly,which was smaller than those of the control group(14.66,13.84,12.68,11.70,11.29 cm),and there was sig-nificant difference in the circumference of injured limbs be-tween the two groups on the 1st,3rd,5th,7th and 14th day after traction(P＜0.05).The VEGF and IL-6 levels in serum of the two groups of rabbits before and after traction were significantly improved,and the difference was statistically significant(P＜0.05).Conclusion:Modified bone traction has a significant efficacy in reducing oblique tibial fractures;its reduction efficacy is better than that of traditional axial bone traction,and the swelling circumference of the injured limb after modified bone traction is smaller than that of traditional axial bone traction,which indicates that it can be used as a new effective traction method on the treatment of tibial frac-tures.
