This prospective study investigated static scapholunate dissociation (SLD) in wrists associated with distal radius fractures. SLD was detected as a widening of the scapholunate (SL) joint interval by SL gap view. Ninety-six distal radius fractures and 154 normal wrists were investigated by SL gap view, which is better for detecting SLD than the standard posteroanterior (PA) view. Incidences of non-symptomatic SLD detected by SL gap view in normal wrists increased by age. In the young age bracket, incidences of SLD in distal radius fractures were significantly higher than in normal wrists. Our results indicated that in patients younger than 30 years old, SLD in distal radius fractures was a fracture-caused abnormality. In those over 30, ascribing SLD to the fracture was difficult. Close examinations, like arthroscopy and dynamic cineradiography, need to be made in patients with SLD associated with distal radius fractures, especially in those younger than 30.
这项前瞻性研究调查了与桡骨远端骨折相关的腕关节静态舟月骨分离（SLD）情况。通过舟月间隙位片将SLD检测为舟月（SL）关节间隙增宽。对96例桡骨远端骨折和154例正常腕关节进行了舟月间隙位片检查，该检查在检测SLD方面比标准正位（PA）片更具优势。正常腕关节通过舟月间隙位片检测出的无症状SLD发生率随年龄增加。在年轻年龄段，桡骨远端骨折中SLD的发生率显著高于正常腕关节。我们的结果表明，在30岁以下的患者中，桡骨远端骨折中的SLD是由骨折导致的异常情况。在30岁以上的患者中，将SLD归因于骨折则较为困难。对于与桡骨远端骨折相关的SLD患者，尤其是30岁以下的患者，需要进行诸如关节镜检查和动态荧光透视等仔细检查。
