Table 2 The distributional pattern of complications according to the fracture types, the presence of medial support, and osteoporosis

From: Does medial support decrease major complications of unstable proximal humerus fractures treated with locking plate?

  1. Values are given as number (percentage).
  2. *Clinically serious major complication.
  3. One female patient had these two complications simultaneously.
  4. RL = reduction loss, SP = screw perforation, AVN = avascular necrosis.
