Pinned feet, coloured X-ray. Top view of the feet of a female patient, showing screws placed throughout the big toe and in the outermost toe on both feet. A fracture is clearly seen in the big toe of the right foot. Pinning is a common solution to mending broken bones, as the pins immobilise the joints and bring the two ends of a fractured bone back together in alignment for healing. It is important that a bone is correctly aligned if it is to heal properly and avoid future complications.
