Unstable ankle fractures and impacted tibial pilon fractures often benefit from provisional external fixation as a temporizing measure prior to definitive fixation. Benefits of external fixation include improved articular alignment, decreased articular impaction, and soft tissue rest. Uniplanar external fixator placement in the Emergency Department (ED ex-fix) is a reliable and safe technique for achieving ankle reduction and stability while awaiting definitive fixation. This procedure involves placing transverse proximal tibial and calcaneal traction pins and connecting the pins with two external fixator rods. This technique is particularly useful in austere environments or when the operating room is not immediately available. Additionally, this bedside intervention prevents the patient from requiring general anesthesia and may be a cost-effective strategy for decreasing valuable operating time. The ED ex-fix is an especially valuable procedure in busy trauma centers and during mass casualty events, in which resources may be limited.
不稳定型踝关节骨折和胫骨平台压缩骨折通常可受益于临时外固定,作为确定性固定前的一种临时措施。外固定的益处包括改善关节对线、减少关节撞击以及让软组织得到休息。在急诊科进行单平面外固定器放置(急诊外固定)是一种可靠且安全的技术,可在等待确定性固定期间实现踝关节复位和稳定。该操作包括在胫骨近端和跟骨放置横向牵引针,并通过两根外固定杆连接这些针。这种技术在条件简陋的环境中或手术室无法立即使用时特别有用。此外,这种床边干预可避免患者需要全身麻醉,并且可能是减少宝贵手术时间的一种具有成本效益的策略。急诊外固定在繁忙的创伤中心以及资源可能有限的大规模伤亡事件中是一种特别有价值的操作。
