ABSTRACT
Objective To evaluate the efficacy of proximal percutaneous pedicle screw fixation combined with distal open osteotomy for sagittal plane imbalance of adult spinal deformity.Methods From January 2011 to June 2015,23 patients with diagnosis of adult spinal deformity were treated with proximal percutaneous pedicle screw fixation combined with distal open osteotomy,there were 8 males and 15 females,aged from 52 to 67 years old (average,62.1 years old).The operation time,blood loss,drainage and perioperative complications were recorded;standing anteroposterior and lateral radiographs of the whole spine were taken and the following parameters were measuredsagittal vertical axis (SVA),lumbar lordosis(LL),pelvic tilt (PT),sacral slope (SS),pelvic incidence/lumbar lordosis mismatch (PI-LL),the above parameters were compared between preoperation and postoperation.Oswestry disability index (ODI) was used to evaluate the clinical efficacy.Results The mean operation time was 253.9±52.1 min,the mean blood loss and drainage was 1 258.5±272.2 ml and 725.1 ± 135.2 ml.No patient got infected,died or had deep vein thrombosis.All patients were followed up for an average of 21.2 months (range,13-52 m).The SVA was restored from 12.6±1.4 cm to 3.5±0.7 cm.In addition,LL,SS,PT,and PL-LL were improved from 13.5°±2.3°,13.9°±2.3°,29.7°±9.6°,29.5°±13.7° to 38.8°±9.6°,25.5°±5.8°,18.9°±8.2°,7.1°±3.6°.The ODI score decreased from 40.3%±12.5% to 13.6%±2.57% at the time of the last follow-up compared with preoperation.Conclusion Proximal percutaneous pedicle screw fixation combined with distal open osteotomy for sagittal plane imbalance of adult spinal deformity could restore the sagittal balance and improve the quality of life.
