The treatment of vertebral burst fractures is still controversial. The aim of the study is to evaluate the purpose ofadditional percutaneous intravertebral reduction when combined with dorsal instrumentation. Methods. In this biomechanicalcadaver study twenty-eight spine segments (T11-L3) were used (male donors, mean age 64.9 ± 6.5 years). Burst fractures of L1were generated using a standardised protocol. After fracture all spines were allocated to four similar groups and randomisedaccording to surgical techniques (posterior instrumentation; posterior instrumentation + intravertebral reduction device + cementaugmentation; posterior instrumentation + intravertebral reduction device without cement; and intravertebral reduction device +cement augmentation). After treatment, 100000 cycles (100–600 N, 3 Hz) were applied using a servohydraulic loading frame. Results.Overall anatomical restoration was better in all groups where the intravertebral reduction device was used (𝑝 < 0.05). In particular,it was possible to restore central endplates (𝑝 > 0.05). All techniques decreased narrowing of the spinal canal. After loading,clearance could be maintained in all groups fitted with the intravertebral reduction device. Narrowing increased in the group treatedwith dorsal instrumentation. Conclusions. For height and anatomical restoration, the combination of an intravertebral reductiondevice with dorsal instrumentation showed significantly better results than sole dorsal instrumentation.
