ABSTRACT
INTRODUCTION:
The sagittal profile of conventionally and surgically treated scoliotic spines is usually analyzed via lateral views of whole-spine X-rays in an upright position. Due to a more hypokyphotic configuration of scoliotic spines, the view onto the upper thoracic vertebrae is often difficult. We investigated whether additional supine MRI measurement supports valid kyphosis angle measurement. PATIENTS ANDMETHODS:
Twenty patients with either short (n = 10, Halm-Zielke, VDS) or long spondylodesis (n = 10, dorsoventral) were assessed 5 years after surgery with standing radiographs and supine whole-spine MRI.RESULTS:
Up to 90% of the upper thoracic vertebrae were invisible on radiographs, whereas MRI allowed visibility of almost many vertebrae. No significant difference in thoracal kyphosis angles could be observed in the comparison of X-ray and MRI data.CONCLUSION:
Thoracal kyphosis measurement of postoperative spines in MRI is a valid diagnostic tool with reliability comparable to that of X-ray. These results cannot be transferred to lumbar lordosis measurement and transferred only partly to coronal COBB angle measurement.
