[Transpedicular osteotomy with dorsal wedge osteotomy: treatment of post-traumatic or postinfection kyphotic malalignment of the thoraco-lumbar spine].
BACKGROUND
The purpose of the study was to evaluate the clinical and radiological follow-up of patients suffering from fixed post-traumatic and postinflammatory kyphotic deformities of the thoracic and lumbar spine and treated by posterior transpedicular wedge resection osteotomy of the spine.


METHODS
A total of 28 patients received a posterior transpedicular wedge resection osteotomy. A prospective follow-up was performed preoperatively, postoperatively and after 3, 6 and 12 months. The kyphotic angle of the fractured segment was evaluated as well as the clinical parameters the self-reported visual analog scale (VAS) and the Oswestry score.


RESULTS
The median pain scores (VAS) and the Oswestry disability scores (p<0.05) decreased significantly from pretreatment to post-treatment. Postoperatively a significant correction of the kyphotic angle could be achieved with a mean of 28 degrees (range 14-44 degrees ). In the follow-up after 1 year there was a 7 degrees increase in kyphosis.


CONCLUSIONS
Transpedicular wedge resection osteotomy of the thoracic and lumbar spine offers a safe surgical technique for the treatment of fixed postinflammatory kyphotic deformities.
