Abstract
A stem-like bone fixation device allows for bony in-growth on its surface and across fracture fragments or between bones that are to be fused.
Claims16
A method for the fixation or fusion of a first bone segment to a second bone segment across a joint, the method comprising:
- providing an elongate implant having a proximal end, a distal end, a longitudinal axis, and a lumen extending through the elongate implant along the longitudinal axis, wherein the elongate implant has a tapered distal end and a first fenestration positioned on a middle portion of elongate implant such that the first fenestration is offset from both the distal end and the proximal end, wherein the elongate implant is made from a metal or metal alloy, wherein the elongate implant comprises external screw threads;
- and
- inserting the elongate implant through the first bone segment and across the joint and into the second bone segment at a first location such that the first fenestration lies at least partly in the joint between the first bone segment and the second bone segment.
The method of claim, wherein the external screw threads are located on a distal portion of the elongate implant.
A method for the fixation or fusion of a first bone segment to a second bone segment across a joint, the method comprising:
- providing an elongate implant having a proximal end, a distal end, a longitudinal axis, and a lumen extending through the elongate implant along the longitudinal axis, wherein the elongate implant has a tapered distal end and a first fenestration positioned on a middle portion of elongate implant such that the first fenestration is offset from both the distal end and the proximal end, wherein the elongate implant is made from a metal or metal alloy;
- inserting a guide pin through the first bone segment and across the joint and into the second bone segment;
- and
- inserting the elongate implant over the guide pin and through the first bone segment and across the joint and into the second bone segment at a first location such that the first fenestration lies at least partly in the joint between the first bone segment and the second bone segment.
