Objective To introduce the design of a new type of external fixator and clinical application. Methods The fixator was designed according to biomechanics and made of aluminum and stainless steel, and tested mechanically and used clinically. Results The results of biomechanical test showed that the fixator could meet clinical needs. 86 cases were reported and 82 cases followed up, who were united within standard limits. Conclusion This new apparatus can be used to treat any fracture of long bones and femoral neck,and it can accurately and easily conduct reduction and fixation. Fixation is reliable. Bones can be lengthened or compressed. It is adjusted easily after operation and can be used conveniently.
