Ultrasound has been used previously in fracture identification, analgesia delivery, and fracture reduction for patients in the emergency department. It has not been previously described as a tool for the guidance of closed fracture reduction in fifth metacarpal neck fractures ("boxer's fractures").
A 28-year-old man presented with hand pain and swelling after punching a wall. Point-of-care ultrasound revealed a significantly angulated fifth metacarpal fracture, which was confirmed with a subsequent hand x-ray study. After an ultrasound-guided ulnar nerve block, closed reduction was performed. Ultrasound was used to assess reduction and ensure improvement in bony angulation during the closed reduction attempts. Post-reduction x-ray study confirmed improved angulation and adequate alignment. Why Should an Emergency Physician Be Aware of This? Point-of-care ultrasound has previously had efficacy in fracture diagnosis and anesthesia delivery for fifth metacarpal fractures. Ultrasound can also be used at the bedside to assist in the determination of adequate fracture reduction when performing closed reduction of a boxer's fracture.
超声已被用于急诊科患者的骨折识别、镇痛和骨折复位。但尚未有研究将其作为第五掌骨颈骨折(“拳击手骨折”)闭合复位的指导工具。
一名 28 岁男性因拳击墙壁后手疼痛和肿胀就诊。即时超声显示第五掌骨明显成角性骨折,随后手部 X 线检查证实了这一诊断。行超声引导下尺神经阻滞麻醉后,进行闭合复位。超声用于评估复位情况,并在闭合复位尝试过程中确保骨角度改善。复位后的 X 射线研究证实了角度的改善和对线的恢复。
为什么急诊医生应该了解这一点?即时超声以前在第五掌骨骨折的骨折诊断和麻醉给药方面具有疗效。在进行拳击手骨折的闭合复位时,超声也可以在床边使用,以协助确定骨折复位是否充分。
