Anatomical measurement of radius in New Zealand rabbits

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. Key words: New Zealand rabbits; Radius; Anatomy
