Superior surgical fixation using a novel orthopaedic expandable fastener

外科医生用金属板和螺钉修复骨折。有时螺钉松动，需要重复手术。可伸缩螺钉更坚固，但更困难，有时无法拆卸。研究小组将测试一种新型螺钉，这种螺钉将骨头固定在一起，强度更大（我们目前的工作显示强度增加了40%），但必要时可以很容易地取出。这笔拨款将允许进行广泛的机械测试，为首次人体临床试验做准备。

Surgeons repair bone fractures using metal plates and screws. Sometimes the screws loosen and the surgery needs to be repeated. Expandable screws are stronger, but more difficult and sometimes impossible to remove. The research team will test a new type of screw that holds the bones together with greater strength (our current work shows 40% stronger) but can be removed easily if necessary. This grant will allow extensive mechanical testing in preparation for a first-in-human clinical trial.
