Kyphosis, loss of vertebral body height (VBH), and clinical and functional outcomes (including the Visual Analog Scale pain score and Oswestry Disability Index) were assessed. We examined the overall effects of VBH in all patients by constructing a linear statistical model and evaluated whether the efficacy was dependent on the characteristics of the patients or fractures.Results We included 63 patients comprising 44 A3.2 and 19 A2 fractures. No patient had worsening neurological symptoms or wound infection. The average rates of change were 67.1% (95% CI 59.1% to 75%) for kyphosis and 88.5% (95% CI 85.6% to 91.3%) for VBH (both p<0.0001). After 1 year, the VBS treatment was more effective for kyphosis in younger patients and at the L1 level, and for VBH in younger patients and cases of Magerl A3.2 fracture.Conclusions This large reported series on VBS validates this surgical treatment. All patients had improved kyphosis and restored VBH. We recommend using VBS rather than open surgery for A3.2 and A2 fractures at the thoracolumbar junction and in young patients. ER -
