Abstract: Internal fixation is one of the most important treatments for fractures.The stability of screws in internal fixation can be influenced by bone mineral density,quality of pilot holes,improper structure and surface characteristics of screws chosen,insertion torque,insertion angle,and screws unfit for the bone holes.Internal fixation of fractures can fail due to the instability of screws.This paper,on the basis of a comprehensive review of the studies on all the above factors influencing the screw stability,proposes effective methods to enhance screw stability so as to improve surgical outcomes of fracture internal fixation.
