Transpedicular bi?vertebrae wedge osteotomy in treatment of post?tubercular spinal deformity: a retrospective study

Abstract Background In the late stage of spinal tuberculosis, bony destruction and vertebral collapse often leads to significant kyphosis, presenting clinically as a painful gibbus deformity, with increased instability, body translations risk neurologic involvement. Spinal osteotomy is thought be suitable for most patients severe rigid kyphosis. The aim this study was evaluate efficacy transpedicular bi-vertebrae technique in Pott’s kyphosis other post-tubercular deformity. Methods Between January 2012 December 2015, 18 deformity underwent wedge osteotomy, minimum follow up 27.0 months. Preoperative postoperative kyphotic angle, sagittal plane parameters (TK thoracic TLK thoracolumbar LL lumbar deformity) vertical axis (SVA) were measured. Oswestry Disability Index (ODI), Visual analog scale (VAS) modified American Injury Association grading (ASIA) preoperative final follow-up documented compared. Results average operation time 305 minutes (range, 200–430 minutes) mean intraoperative blood loss 425 mL 200-700 mL). angles decreased from 80.3° 28.5°-130.8°) preoperatively 26.1° 7.0°-63.3°) at ( P <0.01). VAS score reduced 5.2(range, 2-9) 0.9(range, 0-2, <0.01) ODI improved 55.3% 46%-76%) 6.3% 2%-18%, At follow-up, there radiographic evidence solid fusion site fixed segments all patients.
