Short oblique shaft fractures of the proximal phalanx – Compression plate fixation

Bending and contouring the plate

The dorsal surface of the proximal phalanx is gently convex. If a straight plate is not adequately contoured to follow this convexity, tightening of the distal screw will open the fracture on its palmar aspect.
To overcome this, the plate is slightly overcontoured so that when the distal load screw is tightened, compression is generated evenly over the whole fracture surface.
