A compression plate which is exactly contoured to the bone surface produces asymmetric compression: only part of the cortex near the plate is compressed. Therefore a compression plate is not meant to be used selfstanding, it will rather be combined with additional means. Two of these have been studied: the increased stability provided by the use of lagging, inclined plate screws was compared to the one provided by the spring effect of a plate prebent for central elevation. 7-hole dynamic compression plates (DCP) and 4.5 mm cortex screws were used to stabilize transverse osteotomies in human tibiae in vitro. Flexural and torsional testing revealed that the use of an inclined lag screw or a prebent plate increases stability compared to the one achieved with an exactly contoured plate alone. Preliminary tests suggest, that a combination of plate lag-screw and prebending offers stability up to high loads.
只有接骨板附近的部分皮质骨受到压缩。因此，加压接骨板并非设计用于独立使用，而是会与其他方法结合使用。已对其中两种方法进行了研究：将使用拉力、倾斜接骨板螺钉所提供的更高稳定性与预弯成中央隆起的接骨板的弹性效应所提供的稳定性进行了比较。使用7孔动力加压接骨板（DCP）和4.5毫米皮质骨螺钉在体外稳定人体胫骨的横向截骨。弯曲和扭转测试表明，与单独使用精确贴合的接骨板相比，使用倾斜拉力螺钉或预弯接骨板可提高稳定性。初步测试表明，接骨板拉力螺钉和预弯相结合可在高负荷下提供稳定性。
