Sacralization: An Anatomical Perspective

Objective: This study examines the gross anatomical features of sacralization of human vertebrae. Methods: Sixty five sacral vertebrae were obtained from the Osteology Section of the Department of Anatomy. The presence of sacralization was noted and the specimen was photographed. Results: Out of 65 bone specimens studied, only one vertebra showed features of bilateral sacralization. Conclusion: Lumbosacral vertebral anomalies are due to segmental defects in the development of the spinal cord. The importance of lumbosacral anomalies lies in the fact, that they weaken the part mechanically and cause instability of the spine. Presence of sacralization may exert pressure on the nerves, muscles, blood vessels and soft tissues of that particular region. Sacralization might result in low back pain and increase the incidence of lumbar disc herniation above the level of sacralization. In the present study, a case of sacralization is demonstrated in a bone highlighting the anatomical features. The presence of such anomalies warrants a careful approach by Orthopaedicians, Neurologists and Radiologists in clinical practice.
