Abstract

A system is provided for inserting and securing, through a suprapatellar region of a leg, a nail into a medullary canal of a bone. The system can include a flexible sleeve configured to be partially inserted in the leg. The flexible sleeve can define a leading end and a trailing end spaced apart from the leading end along a first axis. The flexible sleeve can define a first cannulation that extends along the first axis between the leading and trailing ends. The first cannulation can be sized to receive therethrough at least the intramedullary nail. The system can further include a retaining member configured support at least a portion of the flexible sleeve. The retaining member can be configured to position the flexible sleeve through the suprapatellar region of the leg such that the flexible sleeve leading end is aligned with the proximal end of the bone. The intramedullary nail can be insertable through the flexible sleeve and into the medullary canal.

Claims9

Dependent claims

A method for implanting an intramedullary nail into a medullary canal in a bone through a suprapatellar region of a leg, the method comprising:

supporting a flexible sleeve with a retaining member, the flexible sleeve defining a leading end, a trailing end spaced apart from the leading end along a first direction, and a first cannulation extending between the leading end and the trailing ends along the first direction;
inserting a rigid sleeve at least partially in the first cannulation of the flexible sleeve, the rigid sleeve defining a leading end, a trailing end spaced apart from the leading end, and a second cannulation extending between the leading end and the trailing ends along the first direction;
and
inserting the flexible sleeve and the rigid sleeve at least partially into the leg such that the leading end of the flexible sleeve is positioned in alignment with a proximal end of the bone;
inserting a wire guide into the second cannulation of the rigid sleeve, the wire guide defining at least one bore;
inserting at least one wire into the at least one bore to align the at least one wire with a desired location on the bone;
and
inserting the intramedullary nail through the flexible sleeve and into the medullary canal.
