Under the different states, keeping or removing psoas muscle, the extended stress (N/mm^2 )of different segments of spine at the flexed and extended positions of hip joint were measured respectively.

Cases recovered completely, and some various complications occurred in 14 cases. Conclusion Harrington rod is an effective internal fixation device for the reduction of fracture and dislocation of vertebra with its longitudinal stress. This device corresponds to the biomechanics of the spinal column. But during the operation, complications should be avoided or diminished by performing strict aseptic technique, bending of the rod to a proper physiological curvature which corresponds to injured spine, doing posterior bone grafting and using corset support after operation.
