Introduction: Vertebral column is centrally placed structure in the body providing stability, posture, motility and transmission of weight of the body. Disruption during development leads to congenital abnormalities. Fusion of Fifth lumbar vertebra with first sacral can be a congenital abnormality or acquired.

Materials and Methodology: The present study was conducted on 100 dried adult human sacrum of both sexes obtained from Department of anatomy, Deccan College of Medical Sciences, Kanchanbagh, Hyderabad in May-June 2018.

Result: In the present study out of 100 sacra there were 24 fusion of last lumbar vertebra with sacrum. In all cases sacralisation was found to be complete and bilateral. The body, spines, transverse processes, laminae, pedicles and the articular processes were all fused. All the fused vertebrae observed belonged to males.

Discussion: In the present study there is blocking of vertebrae in about 24% of cases. All the fused vertebrae belonged to males showing higher incidence of blocking of vertebrae in males. Magora and Schwartz in 1978 found sacralisation in 20.8% of cases. 1.7% to 14% of sacralisation was reported by Castellvi et al in 1983.

Key words:  Congenital, vertebrae, Sacralisation, blocking.
