Diagnostic ultrasound was used in 103 patients with a clinically suspected fracture of the scaphoid bone in order to achieve an early diagnosis. There were 48 women and 55 men aged 10-75 years (mean 31.4 years) tested with ultrasound. Of the patients, 72 were tested within 3 days after injury the remainder between 4 and 42 days. Fracture was confirmed radiologically in 27. We found that the ultrasound test, applied with a frequency of 1 MHz and intensity of 0.5 W/cm2 and 2.0 W/cm2 for 30s, had a sensitivity of 37 per cent and a specificity of 61 per cent. We thus conclude that ultrasound is not suitable for early diagnosis of scaphoid fracture.
为了实现早期诊断，对103例临床疑似舟状骨骨折的患者使用了诊断性超声。对48名女性和55名年龄在10至75岁（平均31.4岁）的男性进行了超声检查。其中72例患者在受伤后3天内接受检查，其余患者在4至42天之间接受检查。经放射学检查确诊骨折的有27例。我们发现，使用频率为1MHz、强度为0.5W/cm²和2.0W/cm²持续30秒的超声检查，其灵敏度为37%，特异性为61%。因此我们得出结论，超声不适用于舟状骨骨折的早期诊断。
