Fractures of the distal radius and ulna are common, and methods of obtaining pain relief prior to their reduction include general anesthesia, intravenous regional anesthesia, and local infiltration of the fracture hematoma (hematoma block). A prospective study of 132 distal forearm fractures treated with hematoma block was undertaken. This group was compared with a control group of 100 patients who had had either general anesthesia or intravenous regional anesthesia. Results revealed no incidence of infection in either group. If appropriate precautions are taken, hematoma block does not increase the risk of infection.
桡骨远端和尺骨骨折很常见，在复位前缓解疼痛的方法包括全身麻醉、静脉区域麻醉以及骨折血肿局部浸润（血肿阻滞）。对132例采用血肿阻滞治疗的前臂远端骨折患者进行了一项前瞻性研究。该组与100例接受全身麻醉或静脉区域麻醉的患者组成的对照组进行了比较。结果显示两组均未发生感染。如果采取适当的预防措施，血肿阻滞不会增加感染风险。
