The efficacy of ultrasonography for the detection of wooden foreign bodies in the foot was analyzed retrospectively. Twenty patients underwent real-time, high-resolution ultrasound studies (7.5 or 10 MHz, linear array transducers) to rule out the presence of a wooden foreign body in their feet. Ten out of the 20 patients had positive ultrasound findings for a wooden foreign body. With the aid of the ultrasound study and preoperative markings, the subsequent mean surgical time was 20.8 minutes, with a 100% retrieval rate of the foreign body. Ultrasound was found to be 100% sensitive in the detection of wooden foreign bodies in the soft tissues of the foot. Ultrasonography should be considered an important diagnostic modality in the foot and ankle surgeon's armamentarium for the detection of retained wooden foreign bodies.
回顾性分析超声检查在足部木质异物检测中的有效性。20例患者接受了实时、高分辨率超声检查（7.5或10MHz，线性阵列换能器），以排除足部存在木质异物。20例患者中有10例超声检查发现足部有木质异物阳性表现。借助超声检查和术前标记，随后的平均手术时间为20.8分钟，异物取出率为100%。发现超声在检测足部软组织中的木质异物时敏感性为100%。超声检查应被视为足踝外科医生用于检测残留木质异物的重要诊断手段。
