Percutaneous Dorsal Instrumentation of Vertebral Burst Fractures: Value of Additional Percutaneous Intravertebral Reposition—Cadaver Study

Figure 8

Bar graphs of the spinal canal compromise. The initial midsagittal diameter before fracture resembles 100%. Bars show the results for each of the four groups after fracture, after treatment, and after cyclic loading. Note that the use of an intravertebral reduction device led to clearance of the spinal canal. After cyclic loading the narrowing of the spinal canal increased in the dorsal instrumentation group.
