The aims of this study were to establish the radiographic features of distal radial fracture malrotation on bone models and then assess the prevalence of distal radial malalignment in a series of extra-articular fractures in adults. We cut distal radial bone models and simulated pronation and supination malrotation in different positions of dorsal angulation. We also reviewed 160 displaced distal radial fractures in 158 adults assessing any malrotation immediately following fracture and after closed reduction. Malrotation was more obvious on lateral than posteroanterior radiographic images. Following a distal radial fracture, we noted malrotation in 58 (36%); 47 (33%) were either into supination or pronation, six definitely into supination and five clearly in pronation. Eleven were not manipulated. Of the remainder, 44 (of 149) (30%) were malrotated, 35 were into pronation or supination and 10 were into pronation. Malrotation was not associated with an ulnar styloid fracture. Distal radial fracture malrotation appears common but underappreciated. Future studies would be needed to determine if malrotation would affect clinical outcome. V.
本研究的目的是确定桡骨远端骨折旋转不良在骨模型上的影像学特征，然后评估一系列成人关节外骨折中桡骨远端对线不良的发生率。我们切割桡骨远端骨模型，并在不同背侧成角位置模拟旋前和旋后旋转不良。我们还回顾了158例成人的160例移位桡骨远端骨折，在骨折后立即及闭合复位后评估是否存在旋转不良。旋转不良在侧位X线片上比正位片上更明显。桡骨远端骨折后，我们发现58例（36%）存在旋转不良；47例（33%）旋前或旋后，6例明确旋后，5例明显旋前。11例未进行手法复位。其余149例中，44例（30%）存在旋转不良，35例旋前或旋后，10例旋前。旋转不良与尺骨茎突骨折无关。桡骨远端骨折旋转不良似乎很常见，但未得到充分认识。未来需要进行研究以确定旋转不良是否会影响临床结果。V.
