Broken is cut/chiseled in half. Then the nail is inserted into the bone (my femur) up near the top.
The "extra" bone comes from the body's natural healing mechanism. If you pull the bone apart slowly enough, the body forms a continuous connection of new bone in the gap. I did 1mm a day, I think.
- q1w2 4y agoWhat actually happens is that the new bone material is initially gelatinous, so as you lengthen the gap, the gelatinous material is elongated and doesn't harden (at least not in the in the middle of the gap). The rate of hardening and the rate of gap extension should be optimized to create the best bone quality. I wonder if then science to find the correct balance has been done.
