Abstract
A bone fixation nail having an elongated body configured and dimensioned for insertion into a bone. The elongated body has a first slot extending from the leading end to a first end and defining first and second wings, the first and second wings configured to splay radially outward upon application of an internal stress thereto.
Claims26
A bone fixation nail, comprising:
- an elongated body configured and dimensioned for insertion into a bone, the elongated body having a leading end and a trailing end;
- and
- a first slot extending through the elongated body from the leading end to a first point on the elongated body and defining first and second wings, the first and second wings configured to splay radially outward upon application of an internal stress thereto.
A system for bone fixation, comprising:
- a bone fixation nail having an elongated body configured and dimensioned for insertion into a bone and a first slot extending through the elongated body from the leading end to a first point on the elongated body, the first slot defining first and second wings, the first and second wings being configured to splay radially outward upon application of an internal stress thereto;
- and
- an expansion device extending from a first end to a second end and having an engagement portion on a first end thereof, the engagement portion being configured and dimensioned to engage the first slot and to cause the first and second wings to splay radially outward.
A method of preparing a bone fixation nail for use in surgery, the method comprising coupling an engagement portion of an expansion device to an expandable end region of a bone fixation nail and arranging the expansion device in a first position in the expandable end region, the engagement portion being moveable relative to the expandable end region to a second position, movement of the engagement portion from the first position to the second position expanding the expandable end region.
A method for bone fixation, comprising the steps of:
- inserting a leading end of a reamer into a first portion of a bone and guiding the reamer through the bone until the leading end exits a second portion of the bone;
- pulling the leading end of the reamer to pull a bone fixation nail into the bone and guiding the bone fixation nail into a target position within the bone, the bone fixation nail having an expandable region to which an expansion device is connected in a first position;
- and
- expanding the expandable region by moving the expansion device to a second position different to the first position.
A bone fixation nail comprising a transverse opening formed adjacent an end of an elongated body thereof, the transverse opening defining an insertion axis extending at an angle to a longitudinal axis of the elongated body and configured to receive a bone fixation element therethrough to prevent rotation of the elongated body relative to the bone.
