Proximal articular, shearing

Compression fracture / shearing fracture

The mechanism of this fracture is a combination of compression and shearing forces. The patient usually presents with angular deviation and malrotation.


Use of lag screw

Be sure to insert the screw as a lag screw, with a gliding hole in the near (cis) cortex, and a threaded hole in the far (trans) cortex.
Inserting a screw, across a fracture plane, that is threaded in both cortices (position screw) will hold the fragments apart and apply no interfragmentary compression.
