Reduction and preliminary fixation

Reduction

Reduction

B1.2 fractures involve the surgical neck of the humerus and the lesser tuberosity.

Sequence of repair:

  1. Reduce and fix the lesser tuberosity to the humeral head (thereby converting the 3-part fracture into a 2-part situation)
  2. Reduce the proximal humeral fragment to the shaft and fix it.

If needed, fix the lesser tuberosity with an additional (cannulated) lag screw.
