Posterior monoaxial screw fixation combined with distraction-compression technology assisted endplate reduction for thoracolumbar burst fractures: a retrospective study

摘要

. Radiological evaluation using plain lateral radiography. ①:Kyphosis angle, ②:vertebral wedge angle; The anterior longitudinal ligament is curly in fracture region. . Correction of the segmental kyphotic angle was performed indirectly via connecting rods distraction proximally and distally in sequence. The ALL and PLL were straightened as the ligamentotaxis. . Reduction of the endplate collapse was performed directly by longitudinal compression of intermediate screws
