Surgical treatment of severe congenital kyphosis in an adult patient: rare clinical observation and a brief literature review

This is the authors' abstract. We don't add key points for this paper.

The paper presents a clinical case of surgical treatment of an adult patient with severe rigid congenital kyphosis developed due to multiple anomalies in the thoracolumbar spine. Surgical intervention included vertebral column resection (VCR) and the deformity correction using segmental third-generation instrumentation with transpedicular fixation. The VCR made it possible to correct the relationship between vertebrae in the anomaly zone, to improve the shape of the spinal canal and increase its volume, and to achieve apparent mobility of the spine at the apex of the kyphosis. Preservation of the anterosuperior portion of the body of the resected vertebra allowed avoiding anterior mesh cage use to support and reconstruct the anterior supporting column of the resected segment. This enabled performing necessary correction of severe kyphotic deformity, reduced the risk of neurological complications, and favored the formation of solid bone block in the long-term period after surgery.
