Fulcrum bending radiograph and its applications
Tóm tắt
Assessing flexibility of the deformity has become an integral part of scoliosis management. The fulcrum bending radiograph has advantages over other kinds of flexibility radiographs. It is useful for assessing the flexibility of scoliosis deformity, comparing the efficacy of scoliosis correction with different instruments or surgical strategies, predicting the amount of scoliosis correction with surgery, determining the fusion levels and predicting spontaneous coupling correction of sagittal and rotational spinal deformities. This article focuses on the development and applications of this technique for scoliosis management.
