To describe our clinical experience with a system named SureShot? Distal Targeting (Smith & Nephew, Memphis, USA) based on magnetic field presence and discuss our suggestions on this technique.
We analysed prospectively 47 patients affected by humeral, tibial or femoral fractures, treated in our institution during a 3-year period of time (August 2010 to September 2013). We considered the following parameters: the time to set up, the time to position a single screw, the effectiveness of the system (drilling ad screwing), the irradiation exposure time during distal locking procedure and surgical complications.
A total number of 96 screws were inserted. The mean preparation time of the device was 5.1 min ± 2 min (range 3-10 min). The mean time for single screw targeting was 5.8 min ± 2.3 min (range 4-18 min). No major complications occurred. Only a few locking procedures were needed to be practiced in order to obtain the required expertise with this targeting device.
According to our results, this device is reliable and valid whenever the correct technique is followed. It is also user friendly, exposes to lower radiation and needs less surgical time compared to relative data from the literature. However, the surgeon should always be aware of how to use the free hand technique in case of malfunctioning of the system.
描述我们使用一种名为SureShot？远端瞄准系统（美国孟菲斯的施乐辉公司）的临床经验，并讨论我们对该技术的建议。
我们前瞻性分析了在3年期间（2010年8月至2013年9月）在我们机构接受治疗的47例肱骨、胫骨或股骨骨折患者。我们考虑了以下参数：设置时间、单个螺钉定位时间、系统有效性（钻孔和拧入螺钉）、远端锁定过程中的辐射暴露时间以及手术并发症。
共插入96枚螺钉。设备的平均准备时间为5.1分钟±2分钟（范围3 - 10分钟）。单个螺钉瞄准的平均时间为5.8分钟±2.3分钟（范围4 - 18分钟）。未发生重大并发症。为了获得使用该瞄准设备所需的专业技能，仅需进行少数锁定操作练习。
根据我们的结果，只要遵循正确的技术，该设备是可靠且有效的。与文献中的相关数据相比，它还使用方便，辐射暴露更低，手术时间更短。然而，在系统出现故障时，外科医生应始终清楚如何使用徒手技术。
