In the diagnosis of ankle injuries routine radiography is often productive. An international survey of the average number of radiographs made of injured ankles suggested that two projections are adequate to detect fractures. This was confirmed in a prospective study of 242 patients coming to a hospital emergency department with recent ankle injuries. All the fractures could be identified on an anteroposterior or a lateral projection, although some were more obvious on an oblique view. As well, all the fractures were associated with malleolar soft-tissue swelling. Thus, radiography for acute ankle injuries could safely be restricted to patients with soft-tissue swelling, and fractures could be diagnosed using only two routine projections, though for management purposes additional projections might be needed. With a policy of limiting the use of radiography substantial cost reductions are possible.
在踝关节损伤的诊断中，常规X线摄影常常能有所发现。一项关于受伤踝关节平均拍摄X线片数量的国际调查表明，两张投照足以检测出骨折。这在一项对242例近期踝关节受伤前来医院急诊科就诊患者的前瞻性研究中得到了证实。所有骨折均可在前后位或侧位投照上识别出来，尽管有些在斜位片上更明显。此外，所有骨折均伴有踝关节软组织肿胀。因此，对于急性踝关节损伤，X线摄影可安全地仅限于有软组织肿胀的患者，仅用两张常规投照即可诊断骨折，不过为了治疗目的可能需要额外的投照。采取限制X线摄影使用的策略可大幅降低成本。
