Although trauma is a major cause of symptomatic scapholunate interosseous ligament (SLIL) pathology, many patients do not recall a specific injury or repetitive trauma. We report on: (1) the prevalence of SLIL signal changes in patients who underwent wrist magnetic resonance imaging (MRI) for various indications; and (2) the prevalence of SLIL signal changes on MRI in patients without prior wrist trauma.
This is a retrospective study evaluating 1021 patients who underwent wrist MRI or magnetic resonance arthrogram. We collected data on SLIL signal changes on MRI. Patients were divided into 6 groups, based on age, to calculate the proportions of SLIL signal changes across different age groups.
There were a total of 317 (31%) patients with SLIL signal changes, of whom 264 (26% from 1021 and 83% from 317) had a documented low clinical suspicion of SLIL pathology. The prevalence was 15% among 18 to 30 years old and increased to 50% in those above 70 years old. Of the 317 patients with SLIL signal changes, 161 (51%) had no documented prior wrist trauma. The prevalence of SLIL signal changes in this group was 28% in 18 to 30 years old and increased to 80% in patients older than 70 years.
Magnetic resonance imaging signal changes demonstrating SLIL pathology in patients of a younger age may be more clinically meaningful as there is a lower prevalence of incidental SLIL pathology in these patients. Furthermore, it should be kept in mind that SLIL changes on MRI in older patients are common and may not represent acute pathology.
尽管创伤是有症状的舟月骨间韧带（SLIL）病变的主要原因，但许多患者并未回忆起特定的损伤或重复性创伤。我们报告：（1）因各种适应证接受腕关节磁共振成像（MRI）的患者中SLIL信号改变的患病率；（2）既往无腕部创伤的患者中MRI上SLIL信号改变的患病率。
这是一项回顾性研究，评估了1021例接受腕关节MRI或磁共振关节造影的患者。我们收集了MRI上SLIL信号改变的数据。根据年龄将患者分为6组，以计算不同年龄组中SLIL信号改变的比例。
共有317例（31%）患者出现SLIL信号改变，其中264例（占1021例的26%，占317例的83%）临床对SLIL病变的怀疑程度较低。患病率在18至30岁人群中为15%，在70岁以上人群中增至50%。在317例有SLIL信号改变的患者中，161例（51%）既往无腕部创伤记录。该组中SLIL信号改变的患病率在18至30岁人群中为28%，在70岁以上患者中增至80%。
在较年轻患者中，磁共振成像显示SLIL病变的信号改变可能更具临床意义，因为这些患者中偶然出现的SLIL病变患病率较低。此外，应记住老年患者MRI上的SLIL改变很常见，可能并不代表急性病变。
