UNASSIGNED: An institutional review board-approved retrospective chart review was conducted of adult patients who underwent diagnostic arthroscopy with a ligamentous wrist injury from 2015 to 2020. Standard posteroanterior, lateral, and clenched fist stress radiographs were reviewed and scapholunate ligament gaps recorded.
UNASSIGNED: A total of 124 patients were included, of which 88 had normal standard radiographs and clenched fist radiographs. The positive predictive value of the clenched fist view was 69%, whereas the negative predictive value was 58%. The sensitivity of the clenched fist view was 40%, while the specificity was 82%. Of those patients with a negative clenched fist view, 42% were found to have an arthroscopic Geissler classification of 3 or higher scapholunate ligament injury.
UNASSIGNED: Despite the emphasis on stress radiographic views, a normal stress clenched fist view does not preclude arthroscopic findings of a Geissler class 3 or greater injury in symptomatic patients. The sensitivity of a clenched fist view is only 40%. These findings question the utility of stress radiographs when assessing for scapholunate ligament injuries.
■对2015年至2020年接受关节镜诊断性腕关节韧带损伤的成年患者进行了机构审查委员会批准的回顾性图表审查。标准后前,横向,回顾握紧的拳头应力X光片,并记录肩胛骨韧带间隙。
■共纳入124例患者,其中88人有正常的标准X光照片和握紧的拳头X光照片。握紧拳头观点的阳性预测值为69%,而阴性预测值为58%。紧握的拳头视图的敏感度是40%,而特异性为82%。在那些握紧拳头的患者中,42%的人被发现有3或更高的肩胛骨韧带损伤的关节镜Geissler分类。
■尽管强调应力射线照相,正常的压力握紧拳头视图并不排除有症状患者的Geissler3级或更大损伤的关节镜检查结果。紧握的拳头视图的灵敏度仅为40%。这些发现质疑应力X线片在评估肩胛骨韧带损伤时的实用性。
