Breakage of instruments in orthopedic surgery is rarely reported but the consequences can be serious for both patients and surgeons. The medical device directive classifies instruments, such as drills and saws into risk class 1 with low approval requirements. Also the number of applications of reusable instruments is not currently limited.
The aim of this study was determine to what extent instrument failure can lead to reportable incidents and how these incidents should be processed.
The study involved an evaluation of clinical cases from our institution with a selective literature review and discussion of the medical device directive.
The experience in our clinic showed that especially breakage of rasps in total hip and knee replacement surgery is associated with a major time extension of the operational procedure, a wider surgical access opening as well as complicated procedures to recover the fragments from the incident site. In individual cases a fenestration of the bone had to be conducted in order to collect the broken piece of the rasp. In one case a revision hip stem had to be used instead of the planned primary stem in order to bridge the fenestration site.
Such consequences of instrument failure were considered to be a reportable incident. A thorough documentation as well as incident reporting to the manufacturer and the Federal authorities are required for a sufficient processing and risk assessment of the incident.
骨科手术中器械断裂的情况鲜有报道,但对患者和外科医生而言,其后果可能很严重。医疗器械指令将诸如钻头和锯片等器械归类为风险等级1,审批要求较低。此外,目前可重复使用器械的使用次数也没有限制。
本研究旨在确定器械故障在何种程度上会导致可报告事件,以及应如何处理这些事件。
该研究包括对本机构临床病例的评估,并进行选择性文献综述以及对医疗器械指令的讨论。
我们诊所的经验表明,在全髋关节和膝关节置换手术中,尤其是锉刀断裂会导致手术时间大幅延长、手术切口扩大,以及从事故现场取出碎片的操作复杂。在个别情况下,必须进行骨开窗以收集锉刀的碎片。有一例不得不使用翻修髋关节柄而不是计划中的初次使用的柄,以跨越开窗部位。
器械故障的此类后果被视为可报告事件。为了对该事件进行充分处理和风险评估,需要进行详尽记录,并向制造商和联邦当局报告该事件。
