In five fresh frozen arm specimens Colles' fracture was simulated by a dorsal wedge osteotomy of the distal radius. A spring load was applied to the cortex of the distal radius fragment exerting a constant traction force in proximal direction. The distal radius fragment showed minimal dorsal angulation as the forearm was positioned in neutral or pronation, assuming the distal radio ulnar joint including its radio ulnar ligament was kept intact. As the forearm was moved into supination the distal fragment angulated dorsally to close the dorsal open gap in spite of the ligament being intact. When the radio ulnar ligament was detached the stability was however lost in any forearm position. The result supports the concept of immobilizing a satisfactorily reduced Colles' fracture in neutral position, possibly in slight pronation but never in supination.
在五个新鲜冷冻的手臂标本中，通过桡骨远端背侧楔形截骨术模拟科雷氏骨折。对桡骨远端骨折块的皮质施加弹簧载荷，向近端方向施加恒定的牵引力。当假设桡尺远侧关节及其桡尺韧带保持完整，且前臂处于中立位或旋前位时，桡骨远端骨折块背侧成角最小。尽管韧带完整，但当前臂旋后时，远端骨折块向背侧成角以闭合背侧开口间隙。然而，当桡尺韧带被切断时，无论前臂处于何种位置，稳定性都会丧失。该结果支持将复位良好的科雷氏骨折固定于中立位、可能轻度旋前但绝不能旋后的观点。
