新西兰大白兔桡骨的解剖学观测

Anatomical measurement of radius in New Zealand rabbits

目的 获取新西兰大白兔桡骨的解剖学数据,为其相关的实验研究提供参考.方法 选取成年新西兰大白兔20只,观察桡骨外形,并测量桡骨长度,前曲度,桡骨中点矢状径及横径.结果 新西兰大白兔桡骨外形与人类相似,稍前曲,前曲度（26.08±2.54）度;桡骨长（70.66±1.91）mm;桡骨中点横径（4.18±0.37）mm;桡骨中点矢状径（3.07±0.29）mm;桡骨中点横径/桡骨全长（0.059±0.005）;桡骨中点矢状径/桡骨全长（0.043±0.004）;平均体质量：（2.88±0.22）kg;桡骨长度与体质量呈正相关,横径与体质量、矢状径与体质量、桡骨横径与长度比较均无明显相关.结论 新西兰大白兔桡骨的解剖特点及测量数据,可为其相关实验研究提供参考.

Objective To obtain anatomical data of radius in New Zealand rabbits and provide references for relevant experimental research. Methods Twenty adult New Zealand rabbits were selected. The contours of radius were observed, and the anatomical parameters including the length and the front curvature of radius, the transverse diameters and the sagittal diameters of the middle of radius were measured respectively. Results The contours of radius were similar to those of human. The length and the front curvature of radius were （70. 66 ± 1. 91） mm and （26. 08 ±2. 54）°. The transverse diameters and the sagittal diameters of the middle of radius were （4. 18±0. 37） mm and （3. 07 ±0. 29） mm. The ratio of transverse diameters/ length was （0.059 ± 0.005） and of sagittal diameters/length was （0. 043 ± 0. 004）. The weight of rabbits was （2. 88 ±0. 22） kg. The length of radius was positively correlated with body weight. The transverse diameters and the sagittal diameters of the middle of radius were not correlated with weight, and the transverse diameters were irrelevant with length. Conclusion The anatomical features and the data of radius in New Zealand rabbits may provide credible references for relevant experimental research.
