What can result from a displaced 5th metatarsal fracture and crushed cuboid bone injury?

Non-union: May require surgery with internal fixation.

Nothing good: If not treated promptly and properly, arthritis, poor biomechanical function at minimum. May develop nerve related dystrophy and other injuries or traumas. Potential for severe diasabilty. Need to have fracture realigned and repair crushed bone: this may require bone grafting and recontructive surgery.

Many problems: The fact that 3 muscles attach to the fifth metatarsal ( the peroneals) and that the fracture is displaced can cause an imbalance in these muscles and a non-healing fracture of that metatarsal. The peroneus longus passes under the cuboid- this muscle stabilizes the inner foot in gait and this crush fracture can cause problems with walking-- you should see your podiatrist for reconstruction.
