ORTHOPAEDIC IMPLANT AND BONE SCREW ASSEMBLY

摘要

An apparatus for treating fractures. The apparatus may include one or both of an implant, such as an intramedullary nail (100), and a fastening assembly (200)), such as a lag screw (202) and compression screw assembly (204). The implant has a proximal section with a transverse aperture (118). The fastening assembly may be received to slide, in a controlled way, in the transverse aperture of the implant. The engaging member and the compression device are configured so that the compression device interacts with a portion of the implant and a portion of the engaging member to enable controlled movement between the first and second bone fragments. This configuration is useful for, among other things, compressing a fracture.
