PURPOSE: To research if bone substitutes are strictly essential to revive the vertebral physique top and enhance the medical final result, in sufferers with thoracolumbar or lumbar AO kind A post-traumatic vertebral fractures, managed with balloon kyphoplasty mixed with posterior screw and rod system.
METHODS: 105 sufferers with post-traumatic thoracolumbar backbone fracture had been recruited. At baseline, the sufferers underwent a CT and an MRI of the backbone. Medical analysis was carried out, utilizing the Visible Analog Scale (VAS) and the Oswestry Incapacity Index (ODI), at baseline, 48 h after surgical procedure, at Three-month follow-up (FU), 6-month FU, 48 h after the instrumentation removing and at 24-month FU. At every FU, VK, regional kyphosis (RK), central wall (MH/PH) and anterior wall (AH/PH) heights had been assessed on lateral backbone X-rays. At 6-month FU, a CT scan of the backbone was carried out to research the fracture therapeutic. The posterior instrumentation was eliminated 7 months after surgical procedure (vary 6-10 months).
RESULTS: A major discount of imply VAS (p?<?zero.05) and ODI (p?<?zero.05) was noticed after surgical procedure; no impairment of those scores was noticed after the instrumentation removing. A major correction of VK, RK, AH/PH and MH/PH was recorded after surgical procedure; no important modifications of those values had been seen at subsequent FU. After the instrumentation removing, solely an RK impairment was recorded, but it surely was not important.
CONCLUSIONS: PMMA or bone substitutes should not essential to maintain the discount of the endplate obtained with the balloon tamp, when BK is carried out within the affiliation with posterior percutaneous pedicle screws instrumentation.
