放射学和骨显像在疑似舟骨骨折的诊断性治疗中的作用存在争议。我们比较了两种诊断策略：重复放射学检查和选择性骨显像。使用已知的放射性核素检查阳性预测值，在一系列连续的78例患者中，评估了两种诊断方法的敏感性和特异性。初始X线片的Kappa值为0.76，但随访X线片的Kappa值降至0.5。同样，在随访X线片中，敏感度从的%下降到30%。骨扫描的特异度为98%。临床怀疑舟状骨骨折的最佳诊断策略是在放射片阴性的患者中进行初始放射学检查和骨闪烁检查。
The role of radiography and bone scintigraphy in the diagnostic management of suspected scaphoid fracture is controversial. Two strategies were compared for patients with initial negative radiographs: repeated radiography versus selective bone scintigraphy.Using the known positive predictive value of scintigraphy, the sensitivity and specificity of both diagnostic strategies were evaluated in a series of 78 consecutive patients. The kappa value for initial radiographs was 0.76 but decreased to 0.5 for follow-up radiographs. Similarly, sensitivity decreased from 64% to 30% in follow-up radiographs. Specificity of the bone scan was 98%.The best diagnostic strategy in the management of clinically suspected scaphoid fractures consists of initial radiography followed by bone scintigraphy in patients with negative radiographs.
