摘要：
A compression screw comprising: a shaft capable of being stretched, the shaft having a proximal end and a distal end, the proximal end of the shaft comprising a bone-engaging feature and the distal end of the shaft comprising a distal screw thread, and the proximal end of the shaft comprising a drive feature for turning the shaft； wherein inserting the compression screw into bone across a fracture line generates a force, and wherein the force generates a stress in the shaft that causes the shaft to stretch to less than its elastic limit； and wherein, after the shaft is inserted into a bone, the shaft attempts to foreshorten to its original un-stretched condition, thereby generating and maintaining compression across the fracture line.
