Scoliosis and fibrous dysplasia of the spine.

STUDY DESIGN

This report is an account of three patients with scoliosis and polyostotic fibrous dysplasia involving the spine. The perioperative course of two patients who underwent posterior spinal arthrodesis is described.

OBJECTIVES

The objective of the study was to show that extensive fibrous dysplasia of the spine and scoliosis can be treated by standard methods of posterior spinal arthrodesis with good results.

SUMMARY OF BACKGROUND DATA

Scoliosis developed in three patients, and two patients underwent spinal arthrodesis. No report that discusses the results of this type of operation in this patient population exists in the literature.

METHODS

Three patients with polyostotic fibrous dysplasia involving the spine and scoliosis were located at our institution. Two of the patients underwent posterior spinal arthodesis in situ; their perioperative courses are described. The course of the nonoperatively treated patient is noted briefly.

RESULTS

A stable posterior spinal arthrodesis was achieved in both patients with no major complications. At the time of the last follow-up visit, both patients had radiographic evidence of a solid fusion mass with no signs of pseudarthrosis or graft resorption. Both patients currently are doing well.

CONCLUSIONS

Scoliosis and its treatment has been unreported in patients with this condition, and this report demonstrates that satisfactory results can be obtained with attention to detail.
