In order to study the effect of pure torsional forces upon the rotational development of the growing tibia, 35 immature rabbits underwent torsional loading of one tibia in vivo with a spring-loaded cylinder while the other tibia was a control. The radiographic results showed rotation occurring only at the epiphysial plate. Histologically this was assocaited with angulation of the hypertrophic cartilage columns occurring as little as 24 hours after loading which with longer periods of loading produced angled primary and secondary trabeculae. Radiographic and histological analyses of the diaphysis using tetracycline labelling and Spalteholtz injection techniques failed to show any evidence of cortical remodelling or reorientation of the cortical vessels of a rotational nature, suggesting that rotational modelling occurs solely at the epiphysial plate.
为了研究纯扭力对生长中胫骨旋转发育的影响，35只未成熟兔子在体内对一侧胫骨施加弹簧加载圆柱体的扭转载荷，另一侧胫骨作为对照。放射学结果显示旋转仅发生在骨骺板处。组织学上，这与加载后仅24小时就出现的肥大软骨柱成角有关，随着加载时间延长，会产生成角的初级和次级小梁。使用四环素标记和斯帕尔托霍尔茨注射技术对骨干进行放射学和组织学分析，未发现任何皮质重塑或皮质血管旋转性重新定向的证据，这表明旋转塑形仅发生在骨骺板处。
