Synostosis Of dorsolumbar spine: An anatomical investigation with emphasis on clinical and embryological details

Research output: Contribution to journalArticlepeer-review


Purpose. The objectives were to study the morphology of fused vertebrae in thoracolumbar region. Materials and Methods. The study included 729 thoracolumbar vertebrae which were macroscopically observed for the fusion and morphological details were observed. Results. It was observed that, there was fusion in three of our specimens. One specimen was having fusion between the two typical thoracic vertebrae. The other one had fusion among the three typical thoracic vertebrae. The third specimen had fusion between the twelveth thoracic vertebrae and the fi rst lumbar vertebra. The average length of body of thoracic vertebrae was 1.8 mms, vertebral foramen diameter was 1.4mms, length of lamina was 1.9 mms and the length of spinous process was 2.6 mms. The same parameters for the fused vertebrae of two typical thoracic was 3.2 mms, 1.1 mms, 4 mms and 4.7 mms respectively. The parameters of fused three typical thoracic vertebrae were 5.2 mms, 1.4 mms, 6.6 mms and 7.9 mms respectively. The average morphometric parameters of the fused thoracolumbar vertebrae were 3.7 mms, 1.4 mms, 4 mms and 3.5 mms respectively. Conclusion. The present study has provided additional information on the anatomy and morphology of dorsolumbar spine synostosis with their embryological basis and clinical implications. We believe that the details are clinically important as they might be associated with neurological signs and symptoms.
