Abstract:
Objective To evaluate the standing bending, traction and fulcrum bending radiographies in the prediction of scoliosis correction. Methods 27 patients with thoracic scoliosis with an average of 16.4 years old were selected for the evaluation. All the patients were treated with the posterior correction and bone grafting fusion, and fixed with the third generation system of the segmental vertebral fixation, such as TSRH, CD, or CD+Horizon. Measurement of the Cobbs angle was carried out in the preoperative posterior anterior radiographies with the natural position, standing bending, traction and fulcrum bending and in the postoperative posterior anterior radiographies. Results Mean of Cobbs angle at the thoracic curve after operation was 31 degrees, which decreased significantly in comparison with the preoperative data. Average correction rate was 51.6%. The postoperative Cobbs angle at the thoracic curve was positively correlated with the preoperative Cobbs angle in the standing bending, traction and fulcrum bending radiographies. It was significantly different from the preoperative Cobbs angle in the standing bending and traction radiographies, while no difference was seen with the fulcrum bending radiography. Conclusion The fulcrum radiography can be used to evaluate the flexibility of the thoracic scoliosis, and is better than the standing bending and traction radiographies. The three methods should be used together for the analysis of the scoliosis to predict the result of the scoliosis correction.
