摘要： A support rod for a hollow, flexible torque transmitting shaft for treating a bone includes support and flex portions. When the rod is received at a desired position within the shaft, the support portion extends through a first non-bendable portion of the shaft. An outer diameter of the support portion substantially corresponds to an inner diameter of the shaft to support the first portion. When the support rod is received at the desired position, the flex portion extends through a second bendable portion of the shaft. The flex portion includes a holding portion having an outer diameter substantially corresponding to an inner diameter of the second portion and a gap portion having an outer diameter reduced relative to the outer diameter of the holding portion to form an annular gap between the gap portion and an inner surface of the holding portion.

摘要： A retrograde intramedullary nail for insertion in the medullary canal of a femur includes a body that is elongate and defines a leading end and a trailing end spaced from each other at a length sufficient to extend from an intercondylar region at least to a subtrochanteric region of the femur. The body further defines a leading portion that extends to the leading end. The leading portion defines at least one locking hole configured to receive a fixation member. The at least one locking hole defines a central hole axis that is oriented to extend through the neck and head of the femur.

摘要： A system for penetrating the lateral cortex of a long bone includes a tubular cortex penetrator having an inner surface and an outer surface, a proximal end, and a distal end comprising a beveled cutting edge configured to penetrate the lateral cortex. A guide wire is configured to pass over the tubular cortex penetrator, and a guide sleeve is configured to surround the outer surface of the tubular cortex penetrator. A hollow extraction screw with an axial bore, a proximal end, a distal end, and a threaded cutting edge is configured to pass through the axial bore of the hollow extraction screw; and the hollow extraction screw is configured to retract into a distal end of a bore through the tubular cortex penetrator.

摘要： A system for treating a bone includes an insertion device for an intramedullary nail. A first end includes a channel extending therethrough so that, when the insertion device is coupled to an intramedullary nail, the channel of the device is aligned with and in communication with a channel of the nail. The system also includes a guide sleeve extending from a proximal end to a distal end and including a first bend extending along a portion of a length thereof so that a longitudinal axis of a distal portion of the sleeve is angled with respect to a longitudinal axis of a remaining portion of the sleeve. In an operative position, the distal end of the sleeve is inserted into the channel of the device and the remaining portion of the sleeve extends toward a lateral side of a bone being treated.
