This study aimed to compare the holding strength of various commercially-available anchorage devices for artificial ligaments, so that surgeons might make a reasoned choice. Tensile tests to failure were performed on screws, bollards, toggles and staples which had been implanted into cadaveric bones. The holding strength of all devices correlated significantly with the local thickness of cortical bone, so it is recommended that anchorages should be placed away from the joint line, into diaphyseal bone if possible. A new trans-cortical grommet was developed which, when used around an AO screw, had significantly greater holding strength than the other devices.
本研究旨在比较各种市售人工韧带锚固装置的握持强度，以便外科医生能够做出合理的选择。对植入尸体骨骼的螺钉、系船柱、肘节和钉进行了拉伸至破坏试验。所有装置的握持强度均与皮质骨的局部厚度显著相关，因此建议锚固应远离关节线，如有可能应置于骨干骨中。研发了一种新型跨皮质索环，当围绕AO螺钉使用时，其握持强度明显高于其他装置。
