Abstract
A femoral intramedullary rod system capable of treating a variety of femoral bone fractures using a uniform intramedullary rod design. The system generally comprising an intramedullary rod defining an opening having an upper surface and a transverse member including a bone engaging portion and a connection portion defining a thru-hole with the nail sized to pass therethrough. A pin is selectively coupled to the transverse member to rigidly assemble the transverse member to the nail when the nail is passed through the thru-hole and the pin is received within the opening.
Claims26
A system for treating bone fractures, the system comprising:
- an intramedullary nail defining an opening, said opening having an upper surface and a lower surface;
- a transverse member including a bone engaging portion and a connection portion, said connection portion defining a thru-hole, said nail being sized to pass through said thru-hole;
- and
- a pin selectively attached to said transverse member and operable to rigidly assemble said transverse member to said nail when said nail passes through said thru-hole and said pin is received within said opening.
A device for treating bone fractures, the device comprising:
- an intramedullary nail defining an opening, said opening having an upper surface and a lower surface;
- a transverse member including means for engaging bone, said transverse member defining a thru-hole, said nail being sized to pass through said thru-hole;
- and
- means for locking said transverse member in position relative to said nail, said locking means including a pin sized to pass through said opening and rigidly assemble said transverse member to said nail.
A method of treating a bone fracture, the method comprising:
- forming a first hole in a femur transverse to the medullary canal;
- introducing a transverse bone engaging member through the first hole, the bone engaging member including a thru-hole, the thru-hole being positioned adjacent the medullary canal;
- forming a second hole into the medullary canal;
- inserting an intramedullary nail into the medullary canal through the second hole, the nail passing through the thru-hole of the bone engaging member, the nail including an opening positioned adjacent the bone engaging member, the opening having an upper surface and a lower surface;
- and
- rigidly assembling the bone engaging member and the nail by passing a pin selectively coupled to the bone engaging member into the opening of the nail.
