Is Bridge Plating of Comminuted Humeral Shaft Fractures Advantageous When Using Compression Plates with Three versus Two Screws per Fragment? A Biomechanical Cadaveric Study

Figure 6

Photographs of exemplified specimens presenting four different catastrophic failure types identified in the current study: (a) bone fracture through the proximal screws without any screw pullout; (b) breakage of proximal screw #3 and simultaneous bending and pullout of screws #1 and #2 (the latter in group 2 only) without any bone fracture; (c) bending and pullout of the proximal screws, followed by a bone fracture through these screws; (d) bone fracture through the three distal screws without any previous screw pullout or bending (in group 2 only).
