Fig. 1From: Effect of the short-segment internal fixation with intermediate inclined-angle polyaxial screw at the fractured vertebra on the treatment of Denis type B thoracolumbar fractureThe illustration of three different fixations for the treatment of Denis type B TL fracture. a Inclined-angle screws were inserted into the fracture vertebra via the posterior approach along with SSIF. b Straight-forward screws were inserted into the fracture vertebra via the posterior approach along with SSIF. c Two pedicle screws above and below the fracture vertebra were inserted via the posterior approach by application of LSIF. TL, thoracolumbar; SSIF, short-segment internal fixation; LSIF, long-segment internal fixationBack to article page
