Sagittal plane alignment
Once a second screw has been inserted into the main proximal segment, the
sagittal plane alignment is fixed. Therefore, check the reduction on the
lateral image intensifier image before the second proximal screw is placed. A
common deformity is that the distal end of the proximal segment is projecting
anteriorly and must be pushed down into appropriate reduction. This is often
accomplished by pushing with a mallet.
