摘要： The device includes a medullary rod that is locked to a bone of a patient and that has at least one threaded hole with an axis parallel to the femoral neck of the bone, at least one self-drilling, self-tapping screw designed to pass through the hole in the rod and to engage the femoral neck of the bone, at least one sleeve designed to fit around a proximal end of the screw and to be threaded into the hole in the rod, and a shoulder on the sleeve for immobilizing the sleeve relative to the rod. According to the invention, the proximal end of the screw has a circular cross section which is formed to slide within a bore in the sleeve. Each sleeve has a threaded exterior portion which engages the threaded hole, and a proximal end portion shaped to allow the sleeve to be threaded into the hole in the rod. The shoulder on the sleeve bears against the rod to immobilize the sleeve relative to the rod when the sleeve has been fully threaded into the hole.

摘要： The present invention is directed toward a method for performing an internal fixation of fractures of tubular bones using a balloon catheter fixation device which is inflated inside the bone and tightened by applying pressure on the catheter outside of the bone to apply a compression force across the fracture site enhancing the stability of the fractured bone and promoting osseous healing.
摘要翻译：本发明涉及一种使用球囊导管固定装置进行管状骨折的内固定的方法，所述球囊导管固定装置在骨内膨胀并且通过在骨外部的导管上施加压力以在骨折上施加压缩力增强骨折的稳定性，促进骨愈合。

摘要： An intramedullary intertrochanteric fracture fixation appliance has an intramedullary rod having an angulated opening to receive a femoral neck screw. The femoral neck screw has a threaded portion at its proximal end of predetermined diameter. A locking element is provided which acts between the neck screw and the wall of the angulated opening to prevent relative rotation between the screw and the rod.
