Based on follow-up studies of forearm fractures in children the connection between malunion and limitation of forearm rotation has been examined. This limitation of forearm rotation is often caused by deviations of the ulnar and radial shaft in the same direction which have not been corrected by growth. With the aid of geometric drawings it is demonstrated that palmar deviations of bones lead to limited supination whereas dorsal deviations must cause reduced pronation. This limitation increases in proportion to the angle of deviation and proximity to shaft middle.
基于对儿童前臂骨折的随访研究，对骨折畸形愈合与前臂旋转受限之间的关系进行了研究。前臂旋转受限通常是由尺骨和桡骨干在同一方向上的偏差所致，且这种偏差未随生长而得到纠正。借助几何图形可以证明，骨骼的掌侧偏差会导致旋后受限，而背侧偏差必然会导致旋前减少。这种受限程度与偏差角度以及距骨干中点的距离成正比增加。
