Fig. 1From: Comparison of monoplanar and polyaxial screw fixation systems in percutaneous intermediate fixation for thoracolumbar fracturesRepresentative images of surgical procedures of a 57-year-old male patient in the MPPS group. a Representative image of MPPSs. b Application of manual forces on the fractured vertebra to correct kyphosis. c Six Jamshidi needles were inserted into the pedicles and vertebral bodies. (d) Six MPPSs were implanted into the thoracolumbar region and two rods with appropriate length and bending were inserted. e TLF was further corrected by applying a hyperlordosing force through the posterior elements before tightening the screws. f The location of internal fixation and correction of kyphosis were confirmed, and the incisions were closedBack to article page
