1. A separation system comprising:
- a stabilizer configured to slide over an introducer for delivery of a bone fixation device to a bone cavity, the stabilizer being further configured to score a proximal end of the bone fixation device;
wherein the stabilizer includes a tube assembly having a cutting distal edge and a swivel assembly engaged to a proximal end of the tube assembly for rotating the tube assembly; and
a separator configured to engage the introducer and to provide an impact to the introducer to separate the introducer from the bone fixation device.

9. A separation system comprising:
-
an introducer having a distal end and a proximal end; a bone fixation device engaged to the distal end of the introducer; a stabilizer advanceable over the introducer to a proximal end of the bone fixation device, the stabilizer having a cutting distal edge to score the proximal end of the bone fixation device; and a separator having a shaft attachable to the proximal end of the introducer, and a hammer slidably disposed along the shaft to provide an impaction force on the introducer to separate the introducer from the bone fixation device. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
