Foreign material may present both a diagnostic and a surgical problem. Most irretrievable foreign bodies are wood and are radiolucent. Ultrasound offers an alternative way of preoperative imaging in these situations. We describe four cases of retained splinters in the hand that were localized with sonography and subsequently removed surgically. This report supports the reliability and efficiency of ultrasound as the primary imaging tool for the detection of foreign bodies if conventional radiographs are negative. Preoperative sonographic localization of the foreign body may be extremely useful to the surgeon and may minimize surgical dissection and operating room time.
异物可能会带来诊断和手术两方面的问题。大多数无法取出的异物是木质的，且在X射线下不显影。在这些情况下，超声提供了一种术前成像的替代方法。我们描述了4例手部残留木屑的病例，这些木屑通过超声检查定位，随后进行了手术取出。本报告支持了超声作为主要成像工具在传统X线片为阴性时检测异物的可靠性和有效性。术前对异物进行超声定位对外科医生可能极为有用，并且可以减少手术切口和手术时间。
