前臂骨折在所有年龄段都很常见。即使相邻的关节没有直接参与,这些骨折具有关节内特征。这些损伤最常见的并发症之一是运动范围的痛苦限制,尤其是内旋和旋后。这通常是由于未被诊断的扭转畸形;然而,近年来,已经开发了新的方法,通过使用断层成像使这些扭转差异可见和可量化。测量原理对应于下肢的扭转测量。计算机断层扫描(CT)或磁共振成像(MRI)扫描是在定义的高度创建。通过搜索某些地标,扭转角是相对于定义的参考线测量的。一种新的替代方案是使用3D改革模型。扭转畸形的存在,特别是半径,导致前臂的内旋和外旋受损。在扭转畸形的存在下,放射性测量可以帮助决定是否需要手术。不像下肢,关于何时指示校正,仍然没有统一的截止值。必须考虑临床和放射学结果,与患者一起做出决定。
Forearm fractures are common in all age groups. Even if the adjacent joints are not directly involved, these fractures have an intra-articular character. One of the most common complications of these injuries is a painful limitation of the range of motion and especially of
pronation and supination. This is often due to an underdiagnosed torsional deformity; however, in recent years new methods have been developed to make these torsional differences visible and quantifiable through the use of sectional imaging. The principle of measurement corresponds to that of the torsion measurement of the lower limbs. Computed tomography (CT) or magnetic resonance imaging (MRI) scans are created at defined heights. By searching for certain landmarks, torsional angles are measured in relation to a defined reference line. A new alternative is the use of 3D reformation models. The presence of a torsional deformity, especial of the radius, leads to an impairment of the
pronation and supination of the forearm. In the presence of torsional deformities, radiological measurements can help to decide if an operation is needed or not. Unlike the lower limbs, there are still no uniform cut-off values as to when a correction is indicated. Decisions must be made together with the patient by taking the clinical and radiological results into account.
