The use of implants is widespread in orthopaedic practice. In recent times screws and plates have increasingly been supplied individually pre-packaged. We hypothesised that there is a potential for an increased risk of infection associated with the practice of using individually packaged screws. In this study an attempt was made to recreate as closely as possible the standard practice of opening screw packets in the operating theatre. The exterior of 50 screw packets was cultured. The outer screw packets were then opened over a draped instrument table above a petri dish. As a control, petri dishes were left open to the air in the same theatre environment. The packet exteriors grew cultures of organisms in 24/50 cases. The act of opening the packets yielded a growth in 7/50 cases. There was no growth on the control petri dishes. The significance of the result and potential solutions are discussed.
植入物在矫形实践中被广泛应用。近年来，螺钉和钢板越来越多地被单独预包装供应。我们假设，使用单独包装的螺钉可能会增加感染的风险。在这项研究中，我们试图尽可能地重现手术室中打开螺钉包的标准操作。对 50 个螺钉包的外表面进行了培养。然后，将外螺钉包在覆盖着手术器械台的培养皿上方打开。作为对照，将培养皿在同一手术室环境中敞开置于空气中。在 24/50 例中，包的外表面培养出了细菌。在 7/50 例中，打开包的操作导致了生长。对照培养皿没有生长。讨论了结果的意义和潜在的解决方案。
