Metallic implants are often involved in the open reduction and internal fixation of fractures. Open reduction and internal fixation is commonly used in cases of trauma when the bone cannot be healed using external methods such as casting. The locking compression plate combines the conventional screw hole, which uses non-locking screws, with a locking screw hole, which uses locking head screws. This allows for more versatility in the application of the plate. There are many factors which affect the functionality of the plate (e.g., screw placement, screw choice, length of plate, distance from bone, etc.). This paper presents a review of the literature related to the biomechanics of locking compression plates and their use as internal fixators in fracture healing. Furthermore, this paper also addresses the materials used for locking compression plates and their mechanical behavior, parameters that control the overall success, as well as inherent bone quality results.
金属植入物常用于骨折的切开复位内固定术。当骨折无法通过诸如石膏固定等外部方法愈合时,切开复位内固定术常用于创伤病例。锁定加压钢板将使用非锁定螺钉的传统螺孔与使用锁定头螺钉的锁定螺孔结合在一起。这使得钢板的应用更具通用性。有许多因素会影响钢板的功能(例如,螺钉放置、螺钉选择、钢板长度、与骨的距离等)。本文对与锁定加压钢板生物力学及其在骨折愈合中作为内固定器的应用相关的文献进行了综述。此外,本文还讨论了锁定加压钢板所用的材料及其力学行为、控制整体成功的参数以及固有的骨质量结果。
