摘要：
A system for orthopedic repair of bones, the system may include a compression screw. The screw may include a blunt tip on one end with tapped threads to allow for greater bone fixation uniform across a threaded portion of the screw. The screw may also include springs, which may be Belleville washers, which provide appropriate compression and tension and prevent excessive loosening of the screw after surgery. The springs allow the screw to retract without losing pressure on the fracture site. The system may be minimally invasive for multiple fractures on a single bone such as calcaneal fractures, and stabilizing long bone fractures without bone plates.
